Klevv CRAS C925 1TB: The Sweet Spot of the Lineup (2026)
Quick answer
The Klevv CRAS C925 1TB makes sense for anyone who wants a PCIe 4.0 drive with real day-to-day capacity and cares more about long-term endurance than chart-topping benchmarks; it's a solid fit for a primary laptop drive, a Mini PC, or a PS5 storage upgrade with room for a real game library.
Read: 7400 MB/s Write: 6300 MB/s Endurance: 1200 TBW Warranty: 5 years Interface: M.2 4.0 x 4
At 1 TB, the Klevv CRAS C925 hits the sweet spot of the DRAM-less PCIe 4.0 lineup, enough capacity for a real game library without giving up its class-leading endurance rating.
Controller & Memory
Inside the Klevv CRAS C925 1TB 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 1 TB model is the middle ground of the range: its 6,300 MB/s write speed and 1,200 TBW endurance both land squarely between the 500 GB variant's lower figures and the 2 TB variant's higher ones, since more NAND dies allow more write parallelism as capacity grows.
With no heatsink required out of the box, the C925 1TB fits laptops, Mini PCs, and the PlayStation 5's M.2 slot without thermal-clearance issues. Klevv positions it against similarly priced DRAM-less PCIe 4.0 rivals like the WD Black SN770 and Crucial P3 Plus; at 1 TB the C925's edge over those rivals is its 1,200 TBW endurance rating and 5-year warranty, both unusually generous for this price tier.

CRAS C925 Performance & Benchmarks
The 1 TB Klevv CRAS C925 is rated for up to 7,400 MB/s sequential reads and 6,300 MB/s sequential writes, with up to 670,000 IOPS on random reads and 980,000 IOPS on random writes, identical random-IOPS figures to the 500 GB model since both use the same controller configuration. The 2 TB model edges ahead on writes at 6,500 MB/s and pulls further ahead on IOPS (700K/1000K) thanks to greater NAND parallelism.

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 1 TB the cache is larger than on the 500 GB model, so this capacity holds its peak write speed over a bigger chunk of any large transfer before slowing down. 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 1 TB CRAS C925 at 1,200 TBW and backs it with a 5-year limited warranty, generous for a budget-tier DRAM-less drive, 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, 1,200 TBW works out to well over a century 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 1TB makes sense for anyone who wants a PCIe 4.0 drive with real day-to-day capacity and cares more about long-term endurance than chart-topping benchmarks; it's a solid fit for a primary laptop drive, a Mini PC, or a PS5 storage upgrade with room for a real game library. Buyers who move huge files constantly, like 4K video editors working directly off the drive, may still want a faster DRAM-equipped model, since the C925 tops out around 6,300 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 a dependable mid-capacity pick: not the fastest PCIe 4.0 SSD at its price, but one of the more durable ones, backed by a genuinely useful 5-year warranty.
