# KLEVV CRAS C925G 1TB: mid-capacity value done right (2026)

The KLEVV CRAS C925G 1TB hits near-ceiling Gen4 speeds of 7,400 MB/s while carrying an unusually generous 1,200 TBW endurance rating and five-year coverage.

Quick answer: The C925G 1TB earns its place as the default pick of the lineup: it pairs near-ceiling 7,400 MB/s reads with double the endurance of the smaller tier, all under a five-year warranty at a value price. Buyers running constant sustained-write workloads should still look at DRAM-equipped alternatives, because HMB designs eventually fall behind during endless transfers. Against the Lexar NM790 the choice is nearly a coin flip on internals, with KLEVV countering through its higher official endurance rating and pre-fitted graphene heatsink. For gaming rigs, general upgrades, and anyone wanting maximum specification per dollar at 1 TB, this drive belongs on the shortlist.

## Performance

Rated figures reach 7,400 MB/s sequential reads and 6,300 MB/s sequential writes over PCIe 4.0 x4, alongside 670,000 random-read and 980,000 random-write IOPS. Independent testing of the platform supports the claims: Tech4Gamers measured around 7,378/6,383 MB/s peak sequential on the 2 TB sibling and singled out its class-leading 4K latency, while Basic Tutorials found their sample slightly below rated numbers yet ahead of the Crucial P3 Plus sequentially. At 1 TB the pseudo-SLC cache grows large enough that ordinary desktop workloads never approach its edge; only continuous multi-hundred-gigabyte transfers reveal the drop toward native NAND throughput once caching ends.

In practical terms: operating systems boot almost instantly, game levels stream without hitching, and large media copies run at near-interface speed until the cache gives way. The L1.2 ultra-low-power state benefits laptop battery budgets. Sustained professional writing remains the one workload category where DRAM-equipped competitors hold an advantage, as mapping operations must share system memory bandwidth through HMB instead of dedicated silicon.

## Endurance, TBW & Warranty

KLEVV covers this drive with a five-year limited warranty and rates endurance at 1,200 TBW - twice the allowance of the 512 GB tier and enough for roughly 65 to 160 years of typical 20-50 GB daily writing. Coverage terminates at whichever limit arrives first, terabytes or years. Underneath those headline figures sits a full protection stack: hardware LDPC error correction, global wear leveling, end-to-end CRC data path protection, thermal throttling safeguards, and sudden power-loss protection noted in detailed reviews of the platform. AES-256 hardware encryption support is included, though reviewers caution it is not always enabled on retail units. No MTBF figure appears in the official product sheet.

## Pros and Cons

**Pros:**

- 7,400 MB/s reads sit near the Gen4 ceiling
- 1,200 TBW endurance doubles the entry tier
- Five-year limited warranty across capacities
- Graphene-copper heatsink fitted at the factory
- Strong 4K latency reported by independent testers
**Cons:**

- Writes trail the 2 TB flagship by 200 MB/s
- DRAM-less design borrows system memory via HMB
- Sustained transfers slow after cache exhaustion
- Brand has thinner retail presence than major rivals


## Verdict

The C925G 1TB earns its place as the default pick of the lineup: it pairs near-ceiling 7,400 MB/s reads with double the endurance of the smaller tier, all under a five-year warranty at a value price.

## Frequently Asked Questions

### Is the KLEVV CRAS C925G 1TB good for gaming?

Very much so. Rated 7,400 MB/s sequential reads place load times among the fastest PCIe 4.0 can deliver, 1 TB holds Windows plus a substantial modern library, and reviewers praise the platform's low 4K latency for smooth level streaming. Being TLC-based, it also avoids the write-endurance worries attached to QLC budget rivals. Installing several massive titles consecutively will eventually saturate the pseudo-SLC cache and slow later copies, but gameplay itself never touches that limitation.

### Is the KLEVV CRAS C925G 1TB compatible with the PS5?

It meets Sony's stated requirements: PCIe 4.0 NVMe with sequential reads above the recommended 5,500 MB/s - this drive rates 7,400 - inside dimensions of roughly 110 x 25 x 11.25 mm including heatsink. Single-sided construction and 2.8 mm total height fit easily, and the thin graphene-copper plate can remain attached inside the console. KLEVV is absent from Sony's official compatibility page, but drives satisfying the published criteria are widely used in PS5 expansion slots without issue.

### How does the C925G 1TB differ from the 512GB version?

Three measurable differences. Write speed rises from 6,200 to 6,300 MB/s under KLEVV's official ratings. Endurance doubles from 600 to 1,200 TBW, which matters if you keep drives for years or write heavily. And the pseudo-SLC cache grows with capacity, extending how long large copy jobs hold peak speed before dropping toward native NAND rates. Read speed, IOPS ratings, warranty length, heatsink, and controller hardware stay identical across both tiers.

### Does the KLEVV CRAS C925G have a DRAM cache?

No - the MAP1602 controller is DRAM-less, storing mapping tables in system memory through Host Memory Buffer rather than on a dedicated chip. This trims cost and power consumption, and independent reviewers describe everyday responsiveness as excellent nonetheless. The compromise surfaces during heavy sustained writes or when system RAM runs tight, scenarios where a DRAM-equipped controller maintains steadier performance. For gaming, office work, and content consumption, most users will never notice the distinction.

### What makes the C925G different from the older CRAS C925?

The G suffix marks the 2025 revision centered on cooling: a new copper-graphene composite heatsink that KLEVV claims drops temperatures about 15 percent below the previous aluminium design, improving thermal headroom for sustained loads. Funky Kit, which reviewed both generations, describes the update as retaining the original's strengths while improving power management and performance. Core architecture - MAP1602 controller, Hynix 238-layer TLC, DRAM-less HMB design - carries over largely unchanged between versions.

### How does the KLEVV CRAS C925G compare to the Lexar NM790?

They are close cousins: both pair Maxio's MAP1602-class DRAM-less controller with SK Hynix 238-layer TLC NAND, delivering similar 7,400-class read speeds and strong efficiency. Distinguishing factors sit in the details - KLEVV fits its graphene composite heatsink at the factory, advertises very high endurance tiers, and includes an Acronis True Image license, while the NM790 typically counters with broader availability and established retail recognition. Performance differences between them fall within run-to-run variance according to published reviews.
