Most contemporary computer systems now incorporate the 16Gbps PCIe 4.0 standard as the fundamental interface for data transmission and solid-state drive storage.
Although the 32Gbps PCIe 5.0 is gradually replacing Gen 4 in many setups, where both generations coexist, the practical speed gains are often less significant than expected. Much of the available software, including Windows, fails to fully utilize the potential. Moreover, PCIe 5.0 options come with a substantial additional cost.
Regarding pricing, SSD costs were climbing and stock levels dropping when this guide was last updated, largely due to surging demand from artificial intelligence applications. As a result, the current prices listed here may differ from those in the referenced evaluations.
The selections that follow highlight the standout performers from our examinations of almost three dozen PCIe 4.0 drives, tailored to diverse requirements. For expanding storage or upgrading, a suitable PCIe 4.0 NVMe SSD awaits. Continue reading for insights, including key considerations for selection.
PCWorld's credibility in evaluating and advising on PCIe 4.0 SSDs stems from our extensive heritage in PC hardware analysis. Our team has scrutinized components for years, conducting thorough assessments that push products to their boundaries—from benchmark results to everyday functionality. As dedicated PC enthusiasts, we identify what elevates a superior drive. Only exceptional models appear in our curated list.
For those seeking high sequential speeds at a reasonable price, the WD Black SN7100 stands out. It remains listed under that branding but will transition to the SanDisk Optimux GX 7100 name soon, following WD's acquisition and subsequent divestiture of SanDisk.
Our tests revealed impressive results from the 2TB SN7100's host memory buffer (HMB) implementation, though it was edged out by a slim lead from the Lexar Play 2280. That said, the SN7100's availability online at the time of publication secures its position as our primary recommendation.
SSDs employing HMB architecture, like the SN7100, leverage the system's own RAM for main caching, potentially boosting sequential speeds while compromising on random operations. Consequently, drives with dedicated DRAM provide superior random and 4K performance for users prioritizing those aspects.
Enhanced random performance can contribute to a more responsive operating system, though the improvement might be subtle in daily interactions.
The WD Black SN7100 includes a standard five-year warranty and 600TBW endurance per terabyte, positioning it as an ideal PCIe 4.0 choice for general consumers and gamers alike.
Describing any current SSD as truly economical is challenging, yet this DRAM-free HMB model offers notable savings. Previously priced at $150 for 2TB, it's now $285 amid market pressures from AI advancements. The related SN5100, rebranded as SanDisk Optimus 5100, persists on shelves unlike many rivals.
The WD Blue SN5100 replaces our prior value option, the WD Blue SN5000, and outperforms it across most evaluations, especially in continuous and sequential tasks. With identical pricing currently, the superior model is the clear preference.
In benchmarks, the Blue SN5100 placed third overall among HMB drives, dominating the 450GB write test by a wide margin. Modern HMB designs no longer sacrifice sequential capabilities.
It comes with a five-year warranty capped at 600TBW per terabyte of storage.
For compact 2230-sized (22mm by 30mm) NVMe SSDs suitable for Steam Deck or similar gadgets, the Crucial P310 excels as the quickest option tested, surpassing expectations significantly.
The P310 outperformed our earlier 2230 favorite, the WD Black SN770M, in all metrics except the 450GB transfer, where the SN770M faltered after depleting its secondary cache around 85%. Such massive operations are uncommon, particularly on portable devices like the Steam Deck.
In March 2026, the 1TB P310 2230 model remained in stock at $169, a bargain relative to full-size 2280 drives. Its 225TBW per terabyte endurance is modest, yet sufficient for the device's lifespan and the accompanying five-year warranty.
For peak velocity without frequent large data shifts, the P310 is the premier 2230 selection.
Designed for next-generation consoles like the PS5, the Seagate Game Drive PS5 NVMe SSD delivers reliable PCIe 4.0 performance through its DRAM caching, crucial for maximizing Sony's hardware.
Since the PS5 lacks HMB support, DRAM-equipped drives avoid dependency on slower secondary caches. Available in 1TB and 2TB sizes, it offers ample room for game libraries. As of March 2026, supply was limited but accessible.
Though PS5-optimized, the Seagate Game Drive works seamlessly in any PCIe M.2 2280-compatible system. It ranked second in our random operations tests among PCIe 4.0 drives. Backed by a five-year warranty and 1,275TBW rating—exceeding typical standards—it's a fail-safe for PS5 users.
The Corsair MP600 Micro targets scenarios needing drives beyond 2230 but short of standard 2280, specifically the 2242 size (22mm by 42mm).
Lenovo popularized 2242 with devices like the Legion Go and certain ThinkPads, and the Corsair MP600 Micro emerges as the top upgrade choice in this category.
While not the absolute fastest PCIe 4.0 drive overall, it leads among 2242 models and holds its own against many 2280 competitors.
Additional notables include the Orico OS5, promoted for PS5 despite its unsupported HMB setup; the Teamgroup T-Create C47, which shines in extended write tasks; and the Lexar NQ780, holding strong amid tough rivals.
The Orico IG740-Pro provides solid speeds and value with useful accessories; the PNY CS2342 suits Steam Deck as a capable 2230 performer for modest loads; and the Teamgroup MP44Q delivers consistent results for routine use.
Addlink's A93/S93 offers dependable DRAM-less PCIe 4.0 NVMe operation that could cut costs, though its heatsink variant competes against faster, similarly priced alternatives.
Recently added, the WD SN850X 8TB outpaces its 2TB predecessor but commands a steep price; the Samsung 990 EVO Plus refines the hybrid 990 EVO, supporting PCIe 4.0 or 5.0 interfaces, capped at PCIe 4.0 speeds for the latter.
To maximize value in SSD purchases, consider the T-Force G50, a cost-effective PCIe 4.0 option excelling in daily computing.
The Kingston NV3 demonstrates that HMB-based DRAM-less SSDs can match top-tier speeds; the Sabrent Rocket Nano 2242 fits niches like Lenovo's Legion Go and ThinkPads, with compatibility for standard slots.
Testing for most listed drives involved Windows 11 64-bit on an X790 motherboard with an i5-12400 processor, paired with 64GB of Kingston Fury DDR5-4800 RAM. Integrated 20Gbps USB and Thunderbolt 4 were available, using Intel integrated graphics. The 48GB tests employed an ImDisk RAM disk occupying 58GB of RAM, while the 450GB file sourced from a 2TB Samsung 990 Pro hosting the OS.
Recent models used Windows 11 24H2 64-bit booted from a PCIe 4.0 Samsung 990 Pro on an Asus Z890-Creator WiFi board. The setup featured a Core Ultra i5 225 CPU with 128GB Crucial DDR5-5600 RAM. It included 20Gbps USB and Thunderbolt 5, with Intel graphics. Drives were installed via a HighPoint 7604A 16-slot PCIe 5.0 RAID card or an Asus ROG M.2 PCIe 5.0 adapter.
We conducted CrystalDiskMark 8, AS SSD 2, and ATTO 4 for peak potential, followed by 48GB and 450GB transfers via Windows Explorer to mimic typical use, and FastCopy for optimal speeds. A 25Gbps RAID 0 array on the HighPoint 7604A served as secondary storage.
Tests occurred on freshly formatted, TRIM-enabled drives for best results. In regular operation, performance may decline as capacity fills, affected by reduced NAND for caching and other variables. Advanced NAND in newer SSDs mitigates this somewhat.
Note that results reflect the specific sample and capacity evaluated. Variations arise from chip counts impacting parallel operations and caching availability. Manufacturers may alter internals periodically. Report any major deviations from our findings.

Jon L. Jacobi traces his tech journey back to the era of manual switch-based computing and has observed storage evolution from tapes and cards to modern solids. With over 20 years at PCWorld testing HDDs, SATA, and NVMe SSDs, his expertise is extensive. As the saying goes, he's encountered plenty.
When selecting a PCIe 4.0 NVMe SSD, prioritize capacity, cost, and warranty duration. Budget options often feature three years, while premium ones extend to five.
Endurance is gauged by TBW ratings, akin to mileage limits in vehicle coverage, estimating writable terabytes before overprovisioned cells deplete. This factors in NAND type and economic viability for replacements.
Today's SSDs endure typical consumer workloads without failure, as endurance studies have confirmed with petabyte-level writes. QLC NAND typically has lower TBW than TLC.
Connection tech is vital; explore PCIe, NVMe, and form factors below, or consult our comprehensive SSD buying guide.
PCIe serves as the prevailing interface for memory buses, delivering up to 4GBps on Gen 3 and over 10GBps on Gen 5. It complements NVMe in M.2 drives. Most M.2 slots support PCIe, with adapters enabling 2280 drives in PCIe bays. PCIe 4.0 requires AMD Ryzen 3000+ or Intel 11th-gen+ CPUs and motherboards; Gen 5 hits 15GBps for storage.
NVMe harnesses PCIe bandwidth and NAND traits like multi-lane access and caching for rapid SSD speeds. See PCWorld's NVMe overview for details.
Not all M.2 drives are PCIe/NVMe; older ones may use SATA or mSATA. Verify compatibility for legacy upgrades.
mSATA appears in aged systems, and U.2 in enterprise, but consumer boards rarely support the latter.
Velocity is key, yet even entry-level modern SSDs are impressively swift—avoid excess. A drive's speed aligns with the host's PCIe generation; a Gen 5 SSD on Gen 3 won't reach full potential.
Expect caps of 3.5GBps on PCIe 3.0, 7.5GBps on 4.0, and over 14GBps on 5.0 in ideal scenarios like benchmarks or multi-queue apps. Windows' single-queue caps all under 4GBps for file copies.
Tip: For quicker transfers, use FastCopy, which outperforms Windows Explorer by twofold or more.
Our foremost PCIe 4.0 SSD choice is the WD Black SN7100, available up to 4TB. The tested 2TB model ranked second in overall benchmarks and stays purchasable, unlike the marginally quicker Lexar Play 2280.
For affordability, we favor the WD Blue SN5100, trailed by the Kingston NV3—both speedy and economical PCIe 4.0 options.
Gaming consoles share PC architecture, so PC-optimized SSDs suit them too. However, the Seagate Game Drive PS5's strong performance and high TBW make it ideal, with DRAM ensuring top random speeds and PS5 compatibility.
For robust assurances, Seagate's higher-end models offer double or triple TBW plus free data recovery. Samsung and WD also uphold reliable standards.
Most brands source identical controllers and NAND from majors; variances mainly involve support and warranties. Reputable makers produce few underperformers.
SSDs suit extended storage, depending on definition. NAND cells might eventually degrade, but a decade of use shows no widespread issues. Expect decades of reliability, though not centuries.
