Kioxia CD8-R model number breakdown

KCD8DRUG3T84 is the Kioxia self-encrypting (SED) model number for the CD8-R 3,840 GB. CD8-R ships three parallel model strings for the same drive: KCD81RUG3T84 (base / SIE — sanitize-instant-erase), KCD8XRUG3T84 (SIE, crypto-erase) and KCD8DRUG3T84 (SED, TCG Opal 2.0 with a security controller). Field by field: KCD8 = CD8 series / D = SED security variant (1 = base, X = SIE) / R = 2.5-inch read-intensive / UG = PCIe Gen4 U.3 dual-port class / 3T84 = capacity.

Quote the full KCD8DRUG3T84 where a self-encrypting drive is a procurement or compliance requirement: the base and SIE strings have no Opal security controller and cannot be enabled in software afterwards.

Application

The CD8-R is Kioxia's read-intensive PCIe 4.0 data center SSD, used for scale-out cloud storage, big-data and IoT ingest, online transaction processing and virtualisation hosts. 3,840 GB SED drives are specified where data-at-rest encryption must be enforced in hardware — government, healthcare, financial and multi-tenant cloud environments — because the TCG Opal controller performs instant crypto-erase on decommissioning instead of a slow block overwrite. The 1,250K IOPS random read and 7,200 MB/s sequential read keep read-heavy mixed workloads within latency SLOs.

QS Compute supplies Kioxia CD8-R and CD8-V data center SSDs — base, SIE and SED variants — for cloud storage, AI data pipelines and virtualisation platforms, with B2B pricing and short sample lead times.
