Built on V-NAND 3-bit MLC technology over a PCIe Gen 3.0 x4 NVMe interface, this SSD reaches sequential read/write speeds up to 3,500/3,300 MB/s, roughly 53% faster than the original 970 EVO. It's rated for up to 1,200 TBW (terabytes written) at the 2TB capacity tested here.
- Capacity: 2TB
- Sequential read/write: up to 3,500/3,300 MB/s
- Endurance: up to 1,200 TBW
- Interface: PCIe Gen 3.0 x4 NVMe, M.2 form factor
Voltage draw is specified at 3.3V with a 5% allowable tolerance for standard PC power delivery.
This drive requires an M.2 NVMe slot on the motherboard; it isn't a drop-in replacement for SATA-only 2.5-inch bays. Samsung's Dynamic Thermal Guard and a nickel-coated controller with heat spreader work together to manage heat during sustained transfers, which matters most in tighter laptop or small-form-factor builds.
- Form factor: M.2 2280, NVMe protocol
- Thermal management: nickel-coated controller plus integrated heat spreader
- Software: Samsung Magician for drive health monitoring and firmware updates
- Platform support: PC systems with an available NVMe M.2 slot
Systems without a native M.2 NVMe slot would need a PCIe adapter card to use this drive.
With 2TB of capacity and up to 1,200 TBW of endurance, this drive suits both a primary boot/game drive upgrade and long-term heavy read/write workloads. A 5-year limited warranty backs the drive for peace of mind on sustained use.
- Capacity tier: 2TB, suited for large game libraries or creative work files
- Endurance: up to 1,200 TBW before reaching wear limits
- Warranty: 5-year limited coverage
- Samsung Magician software can track drive health and remaining endurance over time
Builders planning future upgrades to PCIe Gen 4 speeds should note this drive is capped by its Gen 3.0 x4 interface.
Pros
- Sequential read speeds up to 3,500 MB/s and sequential write speeds up to 3,400 MB/s over PCIe 4.0
- Random read performance up to 690K IOPS on the 500GB and 1TB capacities
- Backward compatible with PCIe 3.0 slots, so it still functions in older motherboards at reduced bandwidth
- Compact M.2 2280 form factor fits standard laptop and desktop M.2 slots without an adapter
- Nickel coating on the controller paired with a heat spreader label manages heat for more consistent sustained performance
Cons
- Full-rated PCIe 4.0 speeds only apply on PCIe 4.0-capable motherboards; PCIe 3.0 systems cap throughput lower
- No heatsink is bundled, so PS5 or tight-clearance installs may need to add one separately
- 1TB capacity may fall short for users storing large game libraries or 4K video libraries without an additional drive
This 1TB SSD runs over PCIe 4.0 NVMe, rated for sequential speeds up to 3,500 MB/s for reads and up to 3,400 MB/s for writes. Random performance reaches up to 690K IOPS for reads on the 500GB and 1TB capacities, figures aimed at hardcore gamers and tech-focused users running gaming, graphics, and data-analytics workloads that benefit from high throughput.
The drive uses a compact M.2 2280 form factor, optimizing power efficiency for both desktop builds and laptops with M.2 slots. Thermal control is handled through a nickel coating on the controller along with a heat spreader label on the NAND chip, intended to manage heat buildup and help sustain performance during longer read and write operations.
Because this drive uses the NVMe protocol over PCIe 4.0, it requires a motherboard M.2 slot that supports NVMe; it is not a SATA-based drive and won't work in SATA-only M.2 slots. It is also backward compatible with PCIe 3.0 motherboards, meaning it will still function on older systems, though throughput will be capped at PCIe 3.0 bandwidth rather than reaching the full 3,500 MB/s rated speed.
The M.2 2280 form factor is the standard length supported by the vast majority of consumer desktop and laptop motherboards. Buyers should confirm their specific system supports NVMe boot and has adequate clearance, since no bundled heatsink is included with the drive itself.
For systems currently running a SATA SSD or an older PCIe 3.0 NVMe drive, moving to this 1TB PCIe 4.0 drive offers a meaningful jump in both sequential and random performance for gaming load times, video editing, and general application responsiveness. Because it's backward compatible with PCIe 3.0, it also works as a straightforward upgrade path for systems that haven't yet moved to PCIe 4.0 hardware.
Buyers managing large game libraries, extensive photo or video archives, or heavy multitasking workloads may find 1TB tight and should plan for a second drive or a higher-capacity model in the same series down the line. Confirming BIOS support for NVMe boot before installing as a primary boot drive helps avoid setup issues.
Pros
- PCIe 4.0 interface reaches up to 7,000 MB/s sequential read, close to double a PCIe 3.0 drive's throughput
- Endurance rated to 600 TBW, enough for years of daily gaming and video editing workloads
- Nickel-coated heat spreader with Dynamic Thermal Guard limits throttling during long sustained transfers
- Compact M.2 2280 form factor slots into desktop motherboards and the PS5 storage expansion bay
- DirectStorage support on Windows 11 speeds up game asset loading
Cons
- Needs a PCIe 4.0 motherboard such as an X570, B550 or TRX40 chipset to reach its rated speeds; PCIe 3.0 boards cap throughput near half that
- M.2 2280 only, with no shorter 2242 option for compact laptops that use a smaller M.2 bay
- Sustained write speed can drop once a transfer outpaces the drive's cache on very large file copies
The 980 PRO runs on a PCIe 4.0 x4 interface paired with Samsung's own Elpis controller, delivering sequential read speeds of up to 7,000 MB/s and fast sequential write speeds to match. It ships in a 1TB capacity built into a compact M.2 2280 form factor, the standard size used by most desktop motherboards and many slim laptops with a free M.2 slot.
- Interface: PCIe 4.0 x4, NVMe protocol
- Form factor: M.2 2280
- Endurance: rated up to 600 TB total bytes written
- Thermal control: nickel-coated heat spreader plus Dynamic Thermal Guard
That endurance figure means the drive is built for repeated large file writes, not just light everyday use, so it holds up under demanding creative or gaming workloads over time.
This drive is confirmed compatible with the PlayStation 5 storage expansion slot as well as PC motherboards. To hit its full rated speed on a PC, the board needs a genuine PCIe 4.0 M.2 slot, commonly found on AMD X570, B550 and TRX40 chipsets and current-generation Intel boards.
- Backward compatible with PCIe 3.0 M.2 slots, though throughput is limited to roughly half the rated speed
- Uses the NVMe protocol, not SATA, so it will not fit a SATA-only M.2 slot
- Windows 11 systems can use DirectStorage to shorten game load times
- Samsung Magician software manages firmware updates and drive health from the desktop
Check your motherboard's M.2 slot specification before buying if hitting the full PCIe 4.0 speed is the goal.
Moving from a SATA SSD to the 980 PRO is a meaningful jump, since PCIe 4.0 throughput can run many times faster than a SATA III drive's ceiling. That difference shows up most in 4K and 8K video editing, where large clips load and scrub more smoothly, and in 3D rendering workflows that read and write large project files repeatedly.
- Gaming: faster level loading and asset streaming, especially with DirectStorage titles
- Video editing: quicker scrubbing and export on high-resolution footage
- 3D and creative work: reduced wait time when saving or reopening large project files
For anyone still on a hard drive or an older SATA SSD, this is a straightforward single-drive upgrade rather than a full system rebuild.
Pros

- Random IOPS: 1550K read / 1200K write
- Endurance rated for 600TBW
- MTBF: 1.5 million hours
Samsung's Magician software helps keep firmware current and provides performance monitoring after installation, though it does not change the drive's underlying rated specifications. These figures represent maximum performance under ideal conditions — actual throughput will vary based on system hardware and workload type.
Built for mainstream PCs, laptops, and consoles that support the M.2 NVMe form factor.
- Requires a PCIe Gen4 M.2 slot to reach full rated speed; still functions on Gen3 slots at reduced throughput
- Compatible with the PS5 for console storage expansion, subject to the console's own drive requirements
- Designed for personal, gaming, and business desktop or laptop use
Because no heatsink is confirmed included in this listing, sustained heavy workloads — particularly console use — may benefit from adding a compatible heatsink to manage temperatures during extended read/write sessions. Checking motherboard or console M.2 slot specifications before purchase avoids a bandwidth mismatch.
Endurance and warranty figures give a sense of how long the drive is built to last under typical use.
- 600TBW endurance and 1.5 million hour MTBF
- 5-year manufacturer warranty
- 1TB capacity for the OS, applications, and a portion of a game or media library
For users with large 4K video libraries or extensive game collections, 1TB can fill up faster than expected, making this better suited as a primary boot drive paired with secondary storage than as sole storage for a heavy media workflow. Samsung Magician software helps track drive health and remaining endurance over the warranty period.
Pros
- Sequential reads up to 7,000 MB/s and writes up to 5,300 MB/s on the 1TB model, well ahead of SATA-based drives
- Up to 1,000,000 IOPS on the 1TB and 2TB capacities for fast random access to game files
- Gen4 PCIe interface in a compact M.2 2280 form factor slots into standard laptop and desktop bays
- Bundled dashboard software lets you monitor drive health and tune game-mode settings from the desktop
- Capacities run up to 2TB, enough headroom for a large modern game library
Cons
- WD states this drive is not intended for NAS or server environments, so it is built for single-PC gaming use only
- Ships without a heatsink, so cases with weak airflow around the M.2 slot may see the drive throttle under sustained transfers
- Full 7,000 MB/s speeds only apply to the 1TB capacity; other capacities post different read/write numbers
The SN850 uses a Gen4 PCIe, M.2 2280 interface built on 3D NAND, giving it a compact footprint that fits both desktop motherboards and most gaming laptops with an open M.2 slot.
- Sequential read up to 7,000 MB/s and write up to 5,300 MB/s (1TB model)
- Up to 1,000,000 IOPS on the 1TB and 2TB capacities
- Capacities available up to 2TB
- M.2 2280 form factor, single-sided
These numbers come from internal WD testing and can shift with the host system, drive capacity, and how full the drive already is, so treat them as a ceiling rather than a guarantee on every machine.
Getting full Gen4 performance requires a motherboard M.2 slot that supports PCIe Gen4 x4; installed in a Gen3 slot, the SN850 still works but tops out at Gen3 speeds instead of its top ceiling.
- M.2 2280 socket required, keyed for NVMe (not SATA M.2)
- No adapter bracket included for PCIe expansion-card installs
- Compatible with desktop PCs and NVMe-capable laptops with a free M.2 slot
Because it ships bare with no heatsink, cases or laptops with limited airflow around the M.2 area benefit from adding a separate heatsink or thermal pad before long gaming sessions.
WD positions the SN850 specifically for gaming rigs, not sustained enterprise workloads. The included WD_BLACK Dashboard software lets you check drive temperature, remaining lifespan, and toggle a game-mode profile from the desktop.
- Not intended for NAS or server environments per WD's own spec sheet
- WD_BLACK Dashboard requires a separate download to access health and tuning tools
- Best suited to a primary game/OS drive rather than 24/7 write-heavy storage
For a single gaming PC or laptop needing fast load times, that focus is a feature; for anyone shopping for constant-write NAS storage, it points toward a different drive line.
Pros
- Sequential read speeds up to 7,100 MB/s and write speeds up to 6,000 MB/s on a PCIe Gen4 NVMe interface
- 2TB of capacity in a compact M.2 2280 form factor leaves room for AAA game libraries and large media files
- Backward compatible with PCIe Gen3 systems, so it still installs in older laptops and desktops
- Confirmed compatibility with handheld consoles including ROG Ally X, Lenovo Legion Go, and AYANEO Kun
- Built with G8 NAND and thermal control aimed at sustained performance under extended read/write loads
Cons
- Full 7,100 MB/s speeds only apply on PCIe Gen4-capable motherboards; Gen3 systems cap throughput well below that figure
- No heatsink is included on this base model, so sustained heavy workloads may need a separate cooling solution or a case with airflow
- M.2 2280 form factor will not fit older 2242 or 2260 slots without an adapter
The P310 uses a PCIe Gen4 NVMe interface in the M.2 2280 form factor, rated for sequential read speeds up to 7,100 MB/s and write speeds up to 6,000 MB/s. It ships with 2TB of storage built on G8 NAND, giving room for large game installs, applications, and media libraries on a single drive.
- Up to 7,100 MB/s sequential read, 6,000 MB/s sequential write
- 2TB capacity, M.2 2280 form factor
- G8 NAND with thermal control for sustained transfers
Crucial lists this generation as roughly twice as fast as the previous Gen3 lineup for everyday tasks such as booting Windows, launching Photoshop or Illustrator, and working across Excel and PowerPoint files.
The drive is confirmed to work with laptops, desktops, and select handheld gaming consoles, including the ROG Ally X, Lenovo Legion Go, and AYANEO Kun. It is also backward compatible with PCIe Gen3 motherboards, though full Gen4 speeds require a Gen4-capable slot to be reached.
- Works in laptops, desktops, and listed handheld consoles
- Backward compatible with PCIe Gen3 systems
- M.2 2280 slot required; not compatible with 2242 or 2260 slots without an adapter
Because top-end speeds depend on the host system's PCIe generation, buyers on older Gen3 boards should expect noticeably lower throughput than the rated Gen4 figures, even though the drive still installs and functions normally.
The P310 works well as either a primary boot drive replacement or a second drive added alongside an existing SSD for extra game and media storage. It includes an Acronis data recovery software offer to help clone an existing drive or back up files during the swap.
- Suited to both primary boot drive upgrades and secondary storage addition
- Includes Acronis cloning and backup software offer
- No included heatsink on this base SKU
For systems running sustained heavy workloads, such as prolonged large file transfers, a separate heatsink or a case with active airflow is worth pairing with the drive to help sustain peak transfer speeds.
Pros
- Sequential read/write speeds up to 7,150/6,300 MB/s on PCIe Gen 4x4
- Also runs on PCIe 5.0 x2 lanes, giving flexibility across different motherboard configurations
- Nickel-coated controller is built to cut power draw while managing heat under sustained transfers
- Samsung Magician software handles firmware updates, encryption, and ongoing drive health monitoring
Cons
- Rated top speeds apply with Intelligent TurboWrite active, and performance can vary once the write cache is exhausted on sustained large transfers

- 1TB capacity sits at the lower end of the 990 EVO Plus lineup, with less headroom for large game or media libraries than the higher-capacity models
The Samsung 990 EVO Plus 1TB is built around the latest NAND memory, rated for sequential read and write speeds up to 7,150 MB/s and 6,300 MB/s respectively when running over a PCIe Gen 4x4 connection. Intelligent TurboWrite 2.0 manages large-file transfers to sustain that performance for bigger workloads rather than just short bursts.
- Up to 7,150 MB/s sequential read
- Up to 6,300 MB/s sequential write
- M.2 2280 form factor, NVMe interface
A nickel-coated controller is designed to reduce power draw while maintaining thermal control, aimed at keeping sustained transfers stable without excess heat buildup.
This drive is built to run on PCIe 4.0 x4 for its full rated speed, but it also supports PCIe 5.0 x2 lanes, giving it flexibility across newer and older motherboard chipsets. Checking whether your motherboard supports PCIe 4.0 or 5.0 through the Intel or AMD chipset documentation is the main step before installing.
- Compatible with PCIe 4.0 x4 and PCIe 5.0 x2
- M.2 2280 slot required
- NVMe protocol for direct CPU-lane data transfer
Because top speeds depend on the PCIe generation available on the motherboard, a PCIe 3.0 system will still work but will not reach the drive's full rated throughput.
Samsung Magician software handles firmware updates, encryption settings, and continuous monitoring of drive health, which keeps the SSD current without manual firmware hunting. For anyone upgrading from a SATA SSD or hard drive, moving to this NVMe drive is a step up in both interface speed and sustained write performance.
- Magician software for firmware and health monitoring
- HMB technology for efficient memory management
- Available in higher capacities within the same product line for future upgrades

- Rated speeds of 7,250/6,900 MB/s apply specifically to the 1-2TB models; other capacities in the line perform differently
- 2TB capacity will fill quickly for gamers stacking multiple large modern titles alongside downloadable content and updates
The SN7100 reaches up to 7,250 MB/s read and 6,900 MB/s write on 1-2TB models, a roughly 35% performance increase over the previous-generation WD_BLACK SSD. It runs on a PCIe Gen4 interface paired with SanDisk's next-generation TLC 3D NAND, aimed squarely at reducing load times during heavy gaming sessions.
Because the drive is purpose-built with laptops and handheld gaming devices in mind, it is engineered to deliver that performance without the higher power draw that can shorten battery life on portable gaming hardware.
Compared with the previous generation, this drive delivers up to 100% better power efficiency, which matters directly for laptops and handheld gaming devices where battery runtime is limited. The WD_BLACK Dashboard software, available for Windows only, lets performance and drive health be monitored and optimized after the SSD is installed, though Mac and Linux users will need a third-party tool for equivalent monitoring.
The drive is manufactured by SanDisk Technologies and distributed under license from Western Digital, continuing the WD_BLACK line's focus on gaming-oriented storage rather than general-purpose enterprise use.
This 2TB model gives space for a sizable game library alongside downloadable content and updates, though heavy gamers who install several large modern titles at once may find that fills up faster than expected. The SN7100 line is also offered in capacities up to 4TB, with the largest model rated for up to 2,400TBW of write endurance, giving an upgrade path within the same drive family for anyone who needs more room later.
Its M.2 2280 form factor and PCIe Gen4 interface make it a straightforward drop-in for laptops and handheld gaming devices that already support Gen4 NVMe storage.

How We Picked the Best SSDs Under $300
Not every fast-looking drive is actually a good buy. We weighed real read/write speeds, endurance ratings (how many terabytes you can write before the drive wears out), price per gigabyte, and how consistently each model holds up in owner reviews rather than just headline marketing numbers.
We also grouped drives by form factor, since an internal M.2 stick and a pocket-sized portable drive solve very different problems even when they cost the same. That distinction matters more than most buying guides admit.
NVMe vs. Portable SSDs
An NVMe SSD plugs directly into your motherboard’s M.2 slot and talks to your system over PCIe, which is why it can hit sequential speeds past 7,000 MB/s. That kind of speed matters for booting your OS, loading large game worlds, and scrubbing through 4K footage without stutter.
A portable SSD, like the Samsung T7 Shield, connects over USB instead. It tops out closer to 1,050 MB/s, but you can carry it between a laptop, a game console, and a friend’s PC without opening a case. If you need speed at your desk, go NVMe. If you need speed you can put in a bag, go portable.
How Much Capacity Do You Actually Need
1TB is the sweet spot for most people — enough for an OS, a handful of AAA games, and everyday files without constant cleanup. If you edit video, shoot RAW photos, or keep a large Steam library, the 2TB drives on this list stretch your budget further per gigabyte.
If you’re planning a fuller upgrade around a similar budget per part, our guide to the best PSUs under $300 covers the component that keeps everything else running reliably once you add faster storage.
Top SSD Picks by Use Case
Once you know NVMe or portable, and roughly how much space you need, the next step is matching a drive to how you’ll actually use it. Here’s how the lineup breaks down by real-world use case rather than raw specs alone.
Best for Gaming Rigs
The WD_BLACK SN850 was built with gaming in mind, and it shows in how consistently it holds peak speed during long load sequences instead of throttling under sustained reads. Its game-mode firmware helps keep frame pacing smooth on drives that also handle background downloads.
If gaming performance is your only priority, our dedicated best SSDs for gaming roundup narrows the field even further by benchmark and price.
Best for Laptops and Handhelds
Thin laptops and handheld gaming PCs run hotter in tighter spaces, so heat-conscious design matters as much as raw speed. The Crucial P310 2TB uses a single-sided design that fits handheld consoles and slim laptops where taller drives simply won’t clear the chassis.
You also get included data-recovery software, which is a nice safety net if you’re moving irreplaceable files during the upgrade.
Best Budget Pick
Not everyone needs the fastest drive on the shelf. The Samsung 990 EVO Plus lands well under $250 while still delivering PCIe 4.0-class speeds most people can’t fully tell apart from pricier options in daily use.
It’s the pick worth checking if your build budget is tighter than $300, but you don’t want to give up brand reliability to save money.
Best Portable SSD for Creators
Photographers and video editors who shoot on location need a drive that survives drops, dust, and the occasional spilled coffee. The Samsung T7 Shield is rated IP65 water- and dust-resistant, with a rubberized shell that shrugs off the bumps a bare internal drive never has to face.
Trade-off: it’s noticeably slower than the internal picks on this list, so treat it as a field and backup drive rather than your primary boot volume.
Best High-Capacity Value
If you want maximum room without stretching past $300, the Samsung 970 EVO Plus 2TB remains one of the most reviewed drives in this category for a reason — proven speed, a mature driver, and enough headroom for a large game or media library.
It’s a slightly older PCIe 3.0 design, so it won’t match the newest PCIe 4.0 drives on paper, but real-world load times are close enough that most people won’t notice the difference.
Best Budget 2TB Option
The Kingston NV3 2TB keeps you under $300 while still offering PCIe 4.0 speeds and a 5-year warranty, making it a solid choice if capacity matters more to you than chasing the absolute fastest benchmark.
For a broader look at how NVMe options compare across price tiers, our best NVMe SSDs guide is worth bookmarking too.
PCIe Gen 4 vs Gen 5: What Actually Matters in 2026
Every drive on this list uses PCIe 4.0, and that’s intentional — Gen 5 SSDs exist, but they run hotter, cost more, and require a Gen 5-capable motherboard slot that most systems still don’t have. Unless you’re doing professional video work that saturates 10,000+ MB/s transfers daily, Gen 4 remains the better value in 2026.
Check your motherboard’s manual before buying any NVMe drive. A Gen 4 SSD will still work in a Gen 3 slot, but it’ll run at Gen 3 speeds, which changes which drive on this list makes the most sense for your build.
Common Mistakes When Buying an SSD Under $300
The most common mistake is buying a SATA SSD by accident, thinking any “SSD” listing is equally fast. SATA drives cap out around 550 MB/s — a fraction of what the NVMe drives here deliver — so always confirm the interface before you buy.
Another frequent error is ignoring the TBW (terabytes written) endurance rating. A drive with a low TBW might be fine for casual use but wear out faster under heavy video editing or constant game installs. Finally, buyers often skip checking PS5 or console compatibility requirements, like heatsink clearance, before ordering.
Installation and Setup Tips
Ground yourself before handling any internal drive to avoid static damage, and make sure your motherboard’s M.2 slot supports the PCIe generation you’re buying. Most modern boards ship with a small heatsink or thermal pad pre-installed over the primary slot — use it, since these drives can throttle under sustained heavy writes without one.
If you’re cloning an existing drive rather than doing a fresh Windows install, use the manufacturer’s free migration software first. It’s faster and less error-prone than a manual file copy, and most of the brands here include a download link with registration.
Once storage is sorted, the next upgrade most people notice is their display. Pairing fast storage with a sharper screen makes load-time improvements easier to actually see — our best monitors under $300 picks cover that side of the build.

Is 1TB or 2TB better for an SSD under $300?
1TB fits most budgets and everyday use, while 2TB makes more sense if you edit video, shoot RAW photos, or keep a large game library. Compare specs and price per gigabyte before deciding.
Do I need PCIe Gen 4 for gaming?
Gen 4 is the current sweet spot for gaming performance and price. Gen 5 offers little benefit for games specifically and often costs significantly more per gigabyte.
Can I use these SSDs in a PS5?
Many NVMe drives on this list work in a PS5 if they meet Sony’s speed requirement and include or support a compatible heatsink. Always check the console’s official compatibility list before installing.
What’s the difference between NVMe and portable SSDs?
NVMe drives install inside your PC or console for maximum speed, while portable SSDs connect over USB for easy transport between devices. Portable drives are slower but far more flexible for backups and travel.
How long do these SSDs typically last?
Most modern NVMe drives are rated for hundreds of terabytes written and carry warranties of three to five years under normal use. Heavy, constant writing shortens lifespan faster than typical gaming or office use.
Picking the right drive comes down to matching the format — internal NVMe or portable — to how and where you’ll actually use it, then sizing capacity to your real files instead of guessing high. Start with the use case that matches your setup, confirm PCIe compatibility with your motherboard, and see current pricing on the models above before you commit. Whichever drive you choose, moving to a faster SSD under $300 is one of the more noticeable upgrades you can make to an aging PC.
