Use Case
7.68 TB is the volume point in the CD8-R line: a single 2.5-inch 15 mm drive carries the capacity of four 1.92 TB units, so a 24-bay 2U chassis reaches 184 TB raw without changing the platform. Read-intensive endurance suits analytics, object storage and CDN tiers, where the write stream is small relative to reads. The SIE and SED variants are the same hardware with sanitize-instant-erase or TCG Opal self-encryption firmware.
