Today we are taking a look at what might be the best SSD on the market today. The Kioxia CM7 has one thing that other mainstream enterprise drives do not have. It is a PCIe Gen5 NVMe SSD. With that said, it is also a first-gen NVMe SSD launching a year before many of its competitors that have still not shown up. In this review, we are going to take a look at the Kioxia CM7 to see what it has to offer.
Kioxia CM7 PCIe Gen5 NVMe SSD Overview
The Kioxia CM7 is the “CM” series SSD which means it is the company’s enterprise offering. On the other hand “CD” is the company’s “data center” series of drives. We expect more performance per drive from the CM series at this point.
We previously covered the Kioxia CM7 as it was one of the first PCIe Gen5 NVMe SSDs we saw on the market. Even today, Solidigm and Micron, as examples, do not have PCIe Gen5 enterprise SSDs out. There is a good chance that those companies will see their first generation PCIe Gen5 NVMe SDDs launch around the time of a second-gen drive from Kioxia at the rate we are going.
This is a 3.2TB capacity point that puts it in the CM7-V series for mixed workloads at 3 DWPD. On the other hand, CM7-R is the company’s read-optimized 1 DWPD option. The big difference is the amount of overprovisioning.
The 2.5″ drive we are looking at today (there is also an EDSFF E3.S version) is only 3.2TB, one of the smaller drives we have looked at recently.
Here is the other side of the drive.
Next, let us take a look at performance.
