Klevv CRAS C925 2TB: The Endurance Champion of the Line (2026)

Posted on by Raymond Chen

Quick answer

The Klevv CRAS C925 2TB makes sense for buyers who want a large, single PCIe 4.0 drive and care more about long-term endurance than chart-topping benchmarks; it fits well as a primary laptop drive, a content-creation scratch disk for moderate workloads, or a PS5 storage upgrade with room for a big game library.

The Klevv CRAS C925 2TB tops the DRAM-less PCIe 4.0 lineup with the fastest writes and the highest endurance rating in the whole three-capacity range.

Controller & Memory

Inside the Klevv CRAS C925 2TB is the same Maxio MAP1602 controller and 238-layer 3D TLC NAND used across the whole C925 line, again with no dedicated DRAM chip; the drive relies on Host Memory Buffer (HMB) technology to keep its mapping tables fast. It runs over a PCIe 4.0 x4 link using the NVMe 1.4 protocol, ships in the standard single-sided M.2 2280 form factor, and includes AES 256-bit hardware encryption for data-at-rest protection. The single-sided PCB keeps the drive thin enough for laptops and runs a bit cooler than double-sided designs.

The C925 sits in Klevv's mainstream tier, positioned above the entry-level C910 and below the flagship C930, and comes in 500 GB, 1 TB, and 2 TB capacities. This 2 TB model tops the range on every performance metric: its 6,500 MB/s write speed and 2,400 TBW endurance both beat the 500 GB and 1 TB variants, since the extra NAND dies let the controller spread writes across more parallel channels.

With no heatsink required out of the box, the C925 2TB fits laptops, Mini PCs, and the PlayStation 5's M.2 slot without thermal-clearance issues, while its capacity also suits content creators and gamers who want a large, single-drive library. Klevv positions it against similarly priced DRAM-less PCIe 4.0 rivals like the WD Black SN770 and Crucial P3 Plus; at 2 TB the C925's edge over those rivals is its 2,400 TBW endurance rating and 5-year warranty, both unusually generous for this price tier.

CRAS C925 Performance & Benchmarks

The 2 TB Klevv CRAS C925 is rated for up to 7,400 MB/s sequential reads and 6,500 MB/s sequential writes, with up to 700,000 IOPS on random reads and 1,000,000 IOPS on random writes, the highest figures in the three-capacity C925 range. The 500 GB and 1 TB models share the same 7,400 MB/s read rating but trail on write speed and IOPS, since they have fewer NAND dies to write across in parallel.

Like nearly every DRAM-less, HMB-based drive, the C925 leans on SLC caching to hit its peak sequential-write number; sustained transfers that exceed the cache fall back toward the NAND's native TLC write speed. At 2 TB the cache is the largest in the range, so this capacity holds its peak write speed over the biggest chunk of any large transfer before slowing down, which matters for buyers moving 4K video files or large game installs. For day-to-day use, booting Windows, loading games, general file work, the drive's read speed and random IOPS matter more than sustained sequential writes, and there it performs in line with other mainstream PCIe 4.0 NVMe drives. Independent reviewers have generally found the C925 line delivers competent, if unremarkable, real-world performance for its price bracket rather than class-leading numbers.

Endurance, TBW & Warranty

Klevv rates the 2 TB CRAS C925 at 2,400 TBW and backs it with a 5-year limited warranty, the highest endurance figure in the range and one of the specific things Tom's Hardware called out as a genuine standout in its review. At a realistic 20-30 GB per day write workload, 2,400 TBW works out to several centuries before the drive reaches its rated endurance limit, far beyond both the warranty period and the practical lifespan of the rest of the PC around it. Klevv also lists a 2,000,000-hour MTBF figure, though that's a population-level statistical average across many drives rather than a promise about any single unit's lifespan. Warranty service runs through Klevv's regional RMA process rather than the retailer directly, so keep your purchase receipt on hand.

Verdict: Is the CRAS C925 Worth It in 2026?

The Klevv CRAS C925 2TB makes sense for buyers who want a large, single PCIe 4.0 drive and care more about long-term endurance than chart-topping benchmarks; it fits well as a primary laptop drive, a content-creation scratch disk for moderate workloads, or a PS5 storage upgrade with room for a big game library. Buyers running constant heavy sustained writes, like professional 8K video editors, should still look at a faster DRAM-equipped flagship instead, since the C925 tops out around 6,500 MB/s writes rather than leading its class. If outright sustained write speed matters more than endurance headroom, the WD Black SN770 is worth comparing at a similar price. Overall this is the strongest capacity in the C925 range: not the fastest PCIe 4.0 SSD at its price, but comfortably the most durable one at 2 TB, backed by a genuinely useful 5-year warranty.

+ Pros

  • 2,400 TBW endurance, the best in the range
  • 5-year manufacturer warranty
  • 6,500 MB/s writes, fastest of the C925 line
  • Single-sided M.2 2280 fits laptops and PS5
  • AES 256-bit hardware encryption included
  • 2TB capacity suits large game and media libraries

- Cons

  • Costs more than the 500GB and 1TB models
  • No DRAM cache, relies on HMB
  • No heatsink included out of the box
  • Not built for professional sustained-write workloads

Frequently Asked Questions

Yes. The 2 TB CRAS C925 pairs 7,400 MB/s sequential reads and 700,000 random-read IOPS with enough capacity for a large modern game library, roughly 30-40 AAA titles depending on size. That combination makes it a strong PCIe 4.0 choice for a dedicated games drive on desktop or as a laptop upgrade. Load times track closely with other PCIe 4.0 NVMe drives using similar controllers, so the gain over a comparable rival is mostly about not running out of space rather than raw speed.

Yes. It meets Sony's published PS5 M.2 SSD requirements: PCIe 4.0 NVMe interface, sequential read speed above the 5,500 MB/s minimum (this drive is rated at 7,400 MB/s), and a compact single-sided design that fits within Sony's size limits even without an added heatsink. Klevv doesn't appear on Sony's official compatibility list by name, but the specifications line up with what the PS5 requires, and Klevv itself markets the C925 line as a PS5-ready upgrade.

No, the 2 TB CRAS C925 is a DRAM-less design. Instead of an onboard DRAM chip, the Maxio MAP1602 controller uses Host Memory Buffer (HMB) technology, borrowing a small slice of the host system's RAM to store its mapping tables. This keeps costs down and lets Klevv offer the drive's 2,400 TBW endurance rating and 5-year warranty at a lower price point than a DRAM-equipped alternative, at some cost to sustained random-write consistency under very heavy workloads.

The 2 TB model is rated at 2,400 TBW, the highest figure in the three-capacity C925 lineup; the 1 TB version is rated at 1,200 TBW and the 500 GB version at 600 TBW, scaling roughly linearly with capacity. At a typical desktop or laptop workload of 20-30 GB written per day, 2,400 TBW would take several centuries to reach, so endurance is a non-issue for mainstream use and only becomes relevant for buyers doing constant heavy writes, like running a busy NAS or server workload.

Yes, modestly. The 2 TB model shares the same 7,400 MB/s sequential read rating as the smaller capacities, but its sequential write speed reaches 6,500 MB/s versus 6,300 MB/s on the 1 TB model and 6,200 MB/s on the 500 GB model, and its random IOPS are also the highest in the range at 700K/1000K. The gap comes from having more NAND dies to write across in parallel. For typical desktop use the difference is barely noticeable, but it shows up more in large sustained file transfers.

Not for typical desktop or laptop use. The C925 ships as a bare single-sided M.2 2280 drive without a heatsink, and its DRAM-less design and moderate power draw mean it doesn't run especially hot under normal workloads. A motherboard M.2 heatsink or PS5 heat spreader can still help during long sustained-write sessions, but it isn't a requirement the way it can be on higher-power flagship PCIe 4.0 or PCIe 5.0 drives.

It can handle moderate video editing workloads reasonably well, especially compressed footage or use as a fast scratch disk alongside a larger bulk-storage drive, thanks to its 6,500 MB/s write speed and roomy 2,400 TBW endurance rating. For sustained 4K or 8K RAW editing with constant large sequential writes, a DRAM-equipped flagship PCIe 4.0 or PCIe 5.0 drive will hold its peak write speed longer once the C925's SLC cache is exhausted. Treat the C925 2TB as a capable secondary or budget-conscious editing drive rather than a professional workstation's primary scratch disk.
