Use Case
The CD8-V is the mixed-use member of KIOXIA's CD8 family, positioned between the read-intensive CD8-R and the PCIe 5.0 CD8P-R/G series. 6.4TB U.2 drives at this tier are typically used for caching, logging and database tiers inside 2U and 4U servers where write endurance matters more than raw sequential throughput.
