The Klevv CRAS C925G ships in a compact box with a clear image of the drive in the centre. Above this image, in the top right-hand corner, is a sticker which holds the drive's capacity (2TB) and maximum Sequential read speed (7,400MB/s). Under this, we find two more icons for the graphene heatsink and the fact that the drive works with PS5. Below the drive's image is a row of five icons for 3D NAND, NVMe 2.0, SLC Caching, Backup software and a 5-year limited warranty.
The rear of the box has a detailed feature list under which is a multi-lingual statement about transmission speed, stable performance and what the drive is good for. Under this is a performance table for all three drives in the range, displaying Sequential read/write speeds. To keep the drive cool, Klevv has used a thin graphene-copper composite heatsink, thinner and lighter than the heatsink supplied with the original CRAS C925.
The 2TB CRAS C925G is built on a single-sided M.2 2280 format. The drive uses a DRAM-less design, Maxio MAP1602 4-channel controller. The MAP1602 is built on a 12nm TSMC process and has a very small footprint with just a 7.1mm x 11mm package. It uses ARM Cortex-R5 architecture; the MAP1602 supports up to 4TB of 2D MLC/TLC or 3D MLC/TLC/QLC with an interface speed of up to 2400MT/s, which is faster than some of its DRAM-less competitors. Error correction is provided by MAXIO Agile ECC 3 Technology, which provides error correction, and the drive also supports AES 256-bit encryption.
Maxio quote Sequential read / write performance figures for the controller of up to 7,400MB/s and 6,500MB/s, respectively. 4K random performance is rated as up to 1,000K IOPS for both random reads and writes.
For the 2TB CRAS C925G Klevv has matched the controller with two packages of Essencore ENFGGP8NC5LR-HR (rebranded SK Hynix) 238-Layer 3D TLC NAND.
