Kioxia has introduced the CM9-DLC enterprise solid-state drive lineup, adding direct liquid cooling compatibility alongside air-cooling support to its PCIe 5.0 CM9 family. Designed to mount adjacent to server cold plates, the dual-port EDSFF E3.S drives comply with the SFF-TA-1008 rev. 3.0a specification. [1][2]
Targeting AI servers and context-caching workloads, the drives come in read-intensive configurations up to 30.72TB with 1 drive write per day and mixed-use configurations reaching 25.6TB at 3 DWPD. Kioxia reported sequential read speeds up to 14,800MB/s and sequential writes up to 11,000MB/s, noting that performance on lower-capacity tiers matches air-cooled models while the 30.72TB version sees lower random IOPS.

Kioxia is currently sampling CM9 Series drives to select customers, but it has not announced pricing, power consumption figures, or general availability dates. [2]

KIOXIA America announced the CM9-DLC today, a set of direct liquid cooling (DLC) models in its CM9 Series of PCIe 5.0 enterprise SSDs. The E3.S drives mount adjacent to cold plates in liquid-cooled servers and also run just fine in air-cooled systems. Capacities reach 30.72TB in the read-intensive (1 DWPD) version and 25.6TB in the
