If you have got a necessity for pace within the knowledge middle, Kioxia hopes to satiate your starvation for blazing quick storage with its new CM7 collection, which is now delivery to prospects. Designed across the PCI Express 5.0 bus and supplied in Enterprise and Datacenter Standard Form Factor (EDSFF) E3.S and a couple of.5-inch kind elements, these newly minted drives serve up dense capacities and 14GB/s of learn throughput.
That’s additionally a notable metric as a result of it approaching the saturation stage of the PCIe 5.0 x4 interface that is on faucet right here. These are NVMe drives, and with out accounting for overhead, the utmost theoretical throughput is round 16GB/s. There’s nonetheless room to ship even quicker throughput than what the CM7 collection delivers, however not an entire lot.
The different notable bit is the continued push in the direction of to the EDSFF E3.S kind issue within the knowledge middle. Kioxia launched the primary EDSFF drives final yr and is now increasing these choices with its CM7 collection.
“PCIe 5.0 will deliver new levels of performance and will usher in a wave of EDSFF form factor SSDs, helping to replace the 2.5-inch form factor for servers and storage,” stated Jeff Janukowicz, analysis vp at IDC. “We expect the EDSFF form factor to grow to over 50% of enterprise SSD unit shipments by 2026. With the new CM7 Series family of SSDs, KIOXIA is well positioned to capitalize on the transition to EDSFF.”
There are literally two variations of the CM7 collection being supplied. One is a mixed-use variant (CM-V) rated for as much as three drive writes per day (DWPD) and supplied in capacities starting from 1.6TB to 12.8TB, and the opposite is a read-intensive model (CM-R) rated for one DWPD and supplied in capacities starting from 1.92TB all the best way to 30.72TB. So it comes right down to a selection between larger endurance or larger storage capability.
Both fashions pair fifth era BiCS Flash 3D triple-level cell (TLC) reminiscence chips with a proprietary Kioxia controller. They’re additionally each constructed to face up to 24/7 enterprise workloads, whereas doubling the efficiency of the earlier era drives.
