Leading PCIe 4.0 SSDs: Expert Selections for 2026

· 5 min read
The SSD market is a bit of a mixed bag right now. While next-gen PCIe 5.0 drives boast impressive 32Gbps speeds, the reality is that PCIe 4.0, with its 16Gbps baseline, remains the practical choice for most systems. You’ll find that today’s computing equipment largely supports PCIe 4.0 as its standard for data transfer and storage. And here's the thing: while PCIe 5.0 is slowly making inroads, often coexisting with PCIe 4.0 in newer machines, the jump in real-world performance isn’t as dramatic as the spec sheet suggests. A lot of current software, including Windows, simply isn’t optimized to truly exploit those higher Gen 5 speeds. Plus, if you’re looking at a PCIe 5.0 drive, you’re still going to pay a premium. That premium is particularly relevant because, let's be blunt, SSD prices are out of control. As we’ve been updating this article, we’ve seen prices surge and availability dwindle, largely a side effect of the AI gold rush gobbling up NAND flash. So, don't expect the prices you see here to align with older reviews; we’re working with the latest, often higher, figures.

Why Our SSD Picks Matter

We've been putting PC hardware through its paces for decades here at PCWorld. Our storage evaluations are exhaustive, pushing every product to its limits, from raw performance benchmarks to the everyday practicalities of actual use. We're PC users ourselves, so we know exactly what makes a storage solution truly stand out. This list isn't just a collection of drives; it’s a distillation of the top performers from nearly three dozen PCIe 4.0 SSDs we’ve tested. Whether you’re planning a system upgrade or simply need to expand your storage, we’ve got a PCIe 4.0 NVMe SSD worth your attention.

WD Black SN7100 SSD/SanDisk Optimux GX 7100: The Smart Sequential Performer

If you’re chasing solid sequential performance without breaking the bank, the WD Black SN7100 should be on your radar. While it's still sold under the SN7100 branding, WD recently divested SanDisk, so expect to see it eventually transition to the SanDisk Optimux GX 7100 name. This drive truly impressed us with its host memory buffer (HMB) performance, particularly the 2TB version. While the Lexar Play 2280 edged it out by a razor-thin margin in some tests, the SN7100’s continued online availability makes it our top pick, which isn’t something we can say for all its competitors. HMB drives like the SN7100 make a trade-off. They use your system's main memory for caching, which can actually lead to faster sequential transfers. However, you'll generally see weaker random performance compared to traditional DRAM-based designs. For most users, especially gamers, this is a minor point; the difference in everyday OS snappiness is often imperceptible. What you get instead is an affordable drive with top-notch HMB capabilities and a five-year warranty, rated for 600TBW per TB of capacity. **Pros:** * Top-notch HMB performance * Affordable * Sexy name **Cons:** * Slower random performance than DRAM designs

WD SN5100/SanDisk Optimus 5100: Best Budget PCIe 4.0 SSD (Relatively Speaking)

Calling any SSD "budget" feels a bit optimistic these days. Case in point: the 2TB version of the WD Blue SN5100, which was once $150, now sits at $285. Thanks, OpenAI. Even so, this DRAM-less (HMB) design offers significant savings compared to many rivals, and crucially, it's still available, unlike much of the competition. You can find it under its current name or as the SanDisk Optimus 5100. The SN5100 is the successor to our previous budget favorite, the WD Blue SN5000. We found the newer drive excels in most tests, particularly with sustained and sequential throughput. If you find both at similar price points, the SN5100 is the clear choice. It also ranked third among all HMB SSDs we've tested, performing exceptionally well on our 450GB file write test. The truth is, with modern HMB designs, you're not sacrificing sequential performance. This drive boasts a five-year warranty, limited by a 600TBW per 1TB capacity rating, and its single-sided 2280 design makes it highly compatible. **Pros:** * Very good PCIe 4.0 performer for most workloads * Single-sided design fits in just about any 2280 slot * Reputable vendor **Cons:** * QLC slows down during very long writes

Crucial P310 (2230): Tailor-Made for Steam Deck

For those of you with a Steam Deck or any other device demanding a compact 2230 NVMe SSD (that’s 22mm wide, 30mm long), the Crucial P310 is genuinely in a league of its own. It’s simply the fastest 2230 SSD we've tested, and by a considerable margin. This drive is available with capacities up to 2TB, a significant plus for handheld gaming devices or mini-PCs. The one drawback is its relatively low TBW endurance rating, something to consider if you're writing vast amounts of data constantly, but for its intended use cases, it's a stellar performer. **Pros:** * Fastest 2230 SSD we’ve tested * Available with up to 2TB of capacity **Cons:** * Low TBW endurance ratingHere's how things shake out with some of the more niche — and some specialized — PCIe 4.0 SSDs we've been looking at.

Crucial's P310: A 2230 Contender for Handhelds

If you're in the market for a 2230 drive, particularly for something like a Steam Deck, the Crucial P310 has pretty much set the benchmark. It consistently outperformed our prior top pick in this form factor, the WD Black SN770M, across nearly all our tests. The one exception? A massive 450GB file transfer, where the SN770M choked at the 85 percent mark, clearly hitting its secondary cache limits. But let's be realistic: who's regularly pushing a 450GB transfer on a handheld? That's just not a typical workload. As of March 2026, the 1TB P310 2230 was still available, and its $169 price tag made it surprisingly affordable, especially compared to its larger 2280 brethren. Its endurance rating, at 225TBW per terabyte, might seem low on paper. However, for a device like a Steam Deck, that's likely more than enough to last the console's lifespan, and it certainly falls within the drive's generous five-year warranty. So, if pure speed is your primary goal for a 2230 drive, and you're not planning on routinely shuffling colossal data sets, the P310 remains the smart pick.

Seagate Game Drive: PS5 Performance, But Check the Price

Next up, we've got the

Seagate Game Drive – Best PCIe 4.0 SSD for PS5

Seagate Game Drive, specifically marketed for the PS5. It’s a very strong contender, boasting overall solid performance and particularly excellent 4K speeds. A low-profile heatsink is a welcome touch for console integration. The biggest selling point, however, might be its astounding 1,275TBW rating, which is more than double the industry average for similar drives, backed by a five-year warranty. What really matters for PS5 owners is its use of DRAM for primary caching. Sony's console doesn't support Host Memory Buffer (HMB), so a DRAM-equipped SSD is essentially mandatory to extract maximum performance. Available in 1TB and 2TB models, this drive ensures you won't run out of space too quickly. Pricing can be a bit steep, and as of early 2026, supply has been tight. Even so, it secured its place as our second-fastest PCIe 4.0 SSD to date in random operations. It's a no-brainer for serious PS5 users, and it'll work just fine in any PC with a standard PCIe M.2 2280 slot. Read our full Seagate Game Drive review for more.

Corsair MP600 Micro: Carving Out the 2242 Niche

The

Corsair MP600 Micro – Best 2242 form-factor SSD

Corsair MP600 Micro is an intriguing option for a more specific form factor: the 2242. This isn't your standard 2230 for handhelds or the ubiquitous 2280 for most PCs. Instead, it targets devices like Lenovo's Legion Go and various Thinkpad portables, which specifically use M.2 slots that are 22mm wide and 42mm long. It's a direct fit, which is crucial for these systems. While it isn't the absolute fastest PCIe 4.0 SSD we've put through its paces, the MP600 Micro punches above its weight. It delivered the best performance among 2242 drives and held its own against many larger 2280 SSDs. Add in its affordable pricing, and you've got a compelling upgrade for that particular hardware segment. Just remember: it's designed for 2242 slots, so don't expect it to squeeze into a smaller 2230 bay. Check current prices, and see our full Corsair MP600 Micro review for the deep dive.

Other Noteworthy PCIe 4.0 SSDs on Our Radar

The PCIe 4.0 SSD market is broader than ever, with drives catering to almost every need and budget. We've seen some interesting entries that don't quite make the top tier for specific categories but still deserve mention. Take the Orico OS5, for instance; it’s marketed for the PS5, but its HMB design isn't actually supported by Sony's console, so that's a pass. On the flip side, the Teamgroup T-Create C47 truly shines when it comes to sustained, super-long writes, a niche that matters for specific workloads. The Lexar NQ780 also put in a surprisingly strong performance against some tough competition, making it a solid, if less talked about, option. For value-conscious buyers, there's the Orico IG740-Pro, a decently priced, fast-enough SSD that even includes some useful extras. Another 2230 option, the PNY CS2342, targets the Steam Deck crowd and performs admirably with lighter workloads. Then there's the Teamgroup MP44Q, a solid choice for everyday computing. If you're willing to save a few dollars and can manage without DRAM, Addlink’s A93/S93 offers decent performance, though the A93 (with its heatsink) faces fierce competition from faster, similarly priced drives. For those at the very high-end, the WD SN850X 8TB SSD is significantly faster than its 2TB sibling, but that performance comes with a staggering premium. Samsung's 990 EVO Plus is a curious hybrid, updating the 990 EVO with support for both PCIe 4.0 and 5.0, though its PCIe 5.0 performance is effectively capped at PCIe 4.0 bandwidth. For stretching your SSD budget without sacrificing too much performance, the T-Force G50 is a strong candidate for everyday PCIe 4.0 tasks. And if you're still skeptical about DRAM-less drives, the Kingston NV3 is a clear example that Host Memory Buffer (HMB) designs can indeed deliver competitive speeds. Finally, the Sabrent Rocket Nano 2242 also hits that specialized 22x42mm form factor, a bespoke fit for Lenovo's Legion Go and Thinkpads, though it’s adaptable to standard slots too.

How We Put PCIe 4.0 SSDs Through Their Paces

Understanding how we benchmark these drives is key to interpreting our recommendations. For most of the SSDs reviewed here, our testing environment runs on Windows 11, 64-bit. The core hardware consists of an X790 motherboard, capable of both PCIe 4.0 and 5.0, paired with an Intel i5-12400 CPU. We equip this system with a generous 64GB of memory, specifically two Kingston Fury 32GB DDR5 4800MHz modules. For connectivity, we're using integrated 20Gbps USB and Thunderbolt 4. Graphics are handled by the Intel CPU/GPU. When it comes to large file transfers, our methodology is precise. For 48GB tests, we utilize an ImDisk RAM disk, dedicating 58GB of our total 64GB memory for this purpose. The even larger 450GB file transfers originate from a 2TB Samsung 990 Pro, which also serves as our operating system drive. This robust setup ensures consistency and provides a clear picture of how each SSD performs under demanding, real-world-simulated conditions.Here's the thing about storage reviews: a lot of it comes down to the rigor of the testing. Without a solid foundation, all those speed numbers are just… numbers. So, before diving into recommendations, it’s worth understanding the environment we used to put these SSDs through their paces.

Inside Our SSD Test Lab

We don’t just plug drives in and run a quick benchmark. Our testing platform for newer SSDs is built around a modern, high-performance setup. We’re talking about Windows 11 24H2, 64-bit, booting from a PCIe 4.0 Samsung 990 Pro. This system runs on an Asus Z890-Creator WiFi motherboard, which supports both PCIe 4.0 and 5.0, ensuring we’re not bottlenecking anything right out of the gate. Processing power comes from a Core Ultra i5 225 CPU, backed by a generous 128GB of memory – specifically, two Crucial 64GB DDR5 5600MHz modules. Integrated 20Gbps USB and Thunderbolt 5 support, coupled with Intel’s CPU/GPU graphics, round out a workstation-grade environment. For mounting the SSDs under review, we use either a HighPoint 7604A 16x 4-slot PCIe 5.0 RAID adapter card or a single-slot Asus ROG M.2 PCIe 5.0 adapter. This setup ensures that we can handle the fastest drives on the market, giving them every chance to show their full potential. Our testing isn't just theoretical; it’s grounded in decades of experience. Jon L. Jacobi, who has personally tested HDDs, SATA SSDs, and NVMe SSDs for PCWorld for over twenty years, brings an unmatched perspective, having seen storage technology evolve from punch cards to solid-state drives. When it comes to benchmarks, we rely on a mix of synthetic and real-world applications. Synthetic tests like CrystalDiskMark 8, AS SSD 2, and ATTO 4 reveal a drive's peak theoretical performance. But we also simulate real-world usage with 48GB and 450GB drag-and-drop transfers via Windows Explorer, and then push the limits with the much faster FastCopy. Our secondary source/destination for these transfers is a two-drive 25GBps RAID 0 array on a HighPoint 7604A 16x PCIe 5.0 adapter card, ensuring we’re testing bottlenecks at the drive level, not the source. Every test starts with a newly formatted and TRIM’d drive to guarantee optimal results. A word of caution, though: our numbers reflect this ideal state. As a drive fills up, performance can degrade because there's less NAND available for secondary caching. However, current generation SSDs, with their faster NAND, tend to be less affected by this. And, crucially, these performance figures are specific to the exact drive and capacity we tested. SSD performance varies, sometimes significantly, with different capacities due to the number of chips available for parallel reads/writes and the total NAND for caching. Vendors also tweak components without much fanfare. If your experience doesn’t align with our reports, let us know. For a more exhaustive explanation, check out PCWorld’s article on how we test internal SSDs.

Navigating the PCIe 4.0 SSD Market

Choosing a PCIe 4.0 NVMe SSD doesn't have to be a headache, but you'll want to prioritize capacity, price, and warranty. While many budget drives offer a standard three-year warranty, you’ll typically find better models backed by a five-year guarantee. A key indicator of long-term reliability is the drive’s TBW (terabytes written) rating. Think of it like a mileage limit on a car warranty; it's the amount of data the vendor believes you can write before the drive’s overprovisioned cells—which replace worn ones—are exhausted. This figure is a calculation based on the NAND type and a dose of financial planning from the manufacturer. That said, it’s worth noting that modern SSDs are remarkably durable. Tech Report’s grueling endurance tests years ago proved that drives can handle petabytes of writes, meaning most consumers won't hit these limits under normal use. Still, if you're comparing, QLC NAND typically has a lower TBW rating than TLC NAND. The connection technology is another detail to watch. We’ve covered more in-depth buying advice in our guide on which type of SSD you should buy, but here are the essentials:

Essential SSD Terminology

* **PCIe**: This is the backbone of modern storage. It’s a high-speed bus that enables memory transfer at incredible speeds – nearly 4GBps for PCIe Gen 3, and over 10GBps for PCIe 5.0. It's the perfect partner for the NVMe protocol used by most M.2 PCIe SSDs. While many M.2 slots are PCIe, some older ones are SATA. You can also pick up adapters to put "gumstick" (2280) M.2 drives into standard PCIe slots. PCIe 4.0 drives are a significant upgrade over 3.0, but they demand an AMD Ryzen 3000-series or Intel Core 11th-gen (or newer) CPU and a compatible motherboard. PCIe 5.0 pushes even further, hitting up to 15GBps for storage. * **NVMe**: Short for Non-Volatile Memory Express, this protocol exploits PCIe’s vast bandwidth and NAND’s unique properties, like multiple lanes and caching, to deliver exceptional SSD performance. For the full technical breakdown, check out PCWorld’s “Everything you need to know about NVMe.” * **M.2**: Don’t assume all M.2 drives are PCIe/NVMe. Before NVMe became prevalent, some M.2 slots and SSDs were mSATA. If you’re upgrading an older machine, confirm whether you need an NVMe or SATA M.2 drive. * **mSATA and U.2**: You might encounter mSATA in older gear, while U.2 SSDs are mostly found in enterprise servers. Consumer motherboard support for U.2 is practically nonexistent. Here's a crucial point: speed matters, but don’t get carried away. Most contemporary SSDs, even the slower variants, are incredibly fast for typical use. A PCIe SSD will only perform at the speed supported by its host device. A PCIe 5.0 SSD, for instance, won't hit its rated speeds on a PCIe 3.0 system. To put some numbers to it: expect around 3.5GBps max from PCIe 3.0, 7.5GBps from PCIe 4.0, and just north of 14GBps with PCIe 5.0. These are optimal speeds, usually seen in synthetic benchmarks or software that fully exploits NVMe's multiple queues. In everyday Windows transfers, however, single-queue limitations often cap all flavors at under 4GBps. So, for most users, there's no need to overspend on the absolute fastest drive. If you *do* want to boost your transfer performance beyond Windows Explorer, try FastCopy—it can be two to three times quicker.
