Use Case
6.4 TB is the middle capacity of the CD8-V line and the one most often specified for hyperconverged nodes, where each host carries its own write-heavy data set rather than streaming to shared storage. 3 DWPD over five years covers the sustained write rate of a database or virtualisation workload without over-provisioning to write-intensive 10 DWPD drives.
