Klevv's range of SSDs covers Gen4 NVMe and 2.5in SATA drives and now they have added a Gen5 flagship drive to the range. The GENUINE G560 is available in 1TB, 2TB and 4TB capacities.  Klevv rates the performance of the 2TB GENUINE G560 as up to 14,000MB/s and 12,000MB/s for Sequential reads and writes respectively. The 4TB drive has the same ratings while the 1TB is slower at 13,000MB/s and 9.500MB/s for reads and writes respectively.  As for random performance, all three drives are rated as up to 1,400,000 IOPS for writes with the 2TB and 4TB drives having the same 1,400,000 IOPS figure for reads with the 1TB getting 1,300,000 IOPS.

At the heart of the G560 is a Phison PS5026-E26  8-channel controller. Built on a 12nm process, the PS5026-E26 uses a combination of ARM Cortex-R5 architecture and Phison's own CoXProcessor 2.0 specialised accelerators which support a flash interface running at up to 2400 MT/s. The G560 has the controller and the Micron 232-layer 3D TLC NAND running at full whack, hence the headline 14,000MB/s Sequential read speed. The 2TB G560 is a dual-sided design using four 512GB NAND packages to achieve its capacity.

Using the default CrystalDiskMark 8 tests we could not only confirm the official 14,000MB/s and 12,000 Sequential read/write maximum figures but we got a bit more out of the drive with test results of 14,538MB/s for reads and 12,932MB/s for writes.

When it came to random performance we couldn't get close to the official 1,400,000 IOPS figure with our 4-threaded tests. The best random read figure we saw was 522,889 IOPS at QD16. Writes were even further away from the official figure at 442,926 IOPS at QD16. However, switching over to the default Peak Performance Profile in CrystalDiskMark 8 we could confirm both official random figures and indeed better them by decent margins with a random read test result of 1,782,201 IOPS. with writes at 1,602,801 IOPS.

To help keep the GENUINE G560 cool Klevv uses a well-designed passive cooler (80.5 x 23.35 x 17.8mm) and an advanced thermal throttling algorithm. The two-part cooler consists of a rugged aluminium heatsink that uses an optimised fin design which fits into a cradle that holds the drive. The cradle runs more or less the full length of the drive, the drive is sandwiched between two high-efficiency thermal pads, one at the top of the cradle and one under the heatsink and the two parts are held in place by four small screws. It seems to work well as the hottest the drive got under benchmarking was 61° C when it being pushd hard.

The KLEVV GENUINE G560 The Klevv CRAS C925 comes with an official license for Acronis True Image HD which is downloadable from the Klevv website.

Pros

• Overall performance
• Endurance.
• Well-designed heatsink.

Cons

• Write speeds in some benchmark tests.

KitGuru says: Klevv's first go at a Gen5 drive is pretty impressive with a narrow but useful range of capacities and very good overall performance. The aluminium heatsink works well at keeping the drive cool and although the drive did get hot during prolonged benchmarking we didn't see any sign of thermal throttling.
