KIOXIA CM7-V E3.S KCM71VJE12T8 — PCIe 5.0 Value Data Center NVMe SSD

Specifications

Overview

The KIOXIA CM7-V is the value tier of the CM7 generation — the same PCIe 5.0 controller, firmware stack and BiCS FLASH TLC media as the CM7-R read-intensive family, but tuned for cost-sensitive mixed-workload deployment where peak random-write endurance is less important than sequential throughput per dollar.

KCM71VJE12T8, KCM71VJE6T40, KCM71VJE3T20 and KCM71VJE1T60 are the E3.S 7.5 mm base model numbers at 12.8 TB, 6.4 TB, 3.2 TB and 1.6 TB. Sequential read reaches 14,000 MB/s and random read 2,450K IOPS — in the same band as the read-intensive CM7-R, which is what makes the V tier attractive for AI data-loading tiers where the drive is read-dominated but the workload mix is unpredictable.

E3.S is the density play: 7.5 mm thickness, 76 mm wide, 112.75 mm long, with the SFF-TA-1001 pinout that the current generation of PCIe 5.0 backplanes expect. Power Loss Protection and end-to-end data protection are standard, so the drive is safe in write-cache-enabled hosts, and the 2,500,000-hour MTTF with a 5-year warranty matches the rest of the KIOXIA enterprise line.

Key Benefits

14,000 MB/s sequential read on PCIe 5.0 for AI dataset loading and media pipelines. Four capacity points from 1.6 TB to 12.8 TB allow one qualification to cover edge and core. E3.S 7.5 mm density doubles drives per rack unit versus 15 mm U.2. PLP and end-to-end protection on every model. Dual-port capable controller supports high-availability x2/x2 topologies.

Applications

AI training data load and checkpoint scratch tiers; content delivery and streaming edge caches; virtualized server boot and VM datastores; cost-sensitive cloud block storage pools; log and telemetry ingestion; HPC scratch on PCIe 5.0 head nodes; tiered storage between SSD cache and nearline HDD.
