Kioxia CM5-V 800GB U.2 NVMe Enterprise SSD (SDFMC06GEA01 / KCM51VUG800G)
Technical Identity
The Kioxia CM5-V SDFMC06GEA01 (also marketed as KCM51VUG800G) is an 800 GB write-intensive enterprise NVMe SSD in the 2.5" U.2 (SFF-8639) form factor with a 15 mm z-height. The drive presents a PCIe 3.0 x4 host interface speaking NVMe 1.3 and is built on Kioxia 64-layer BiCS3 3D TLC NAND paired with an in-house controller. Kioxia is the brand that replaced Toshiba Memory Corporation in October 2019, so drives labeled "Toshiba CM5-V" and "Kioxia CM5-V" are the same product family with identical firmware lineage. This unit is sold refurbished by T.E.S IT-SOLUTIONS, lab-tested and SMART-verified before dispatch.

What This Is NOT
NOT a SATA or SAS drive — it is a native NVMe device and will not initialize in a SATA/SAS backplane.
NOT an M.2 SSD — the form factor is 2.5" U.2 (SFF-8639), and the 15 mm z-height does not fit a standard 7 mm SATA tray.
NOT a read-intensive drive — for ~1 DWPD read-centric workloads, use the CM5-R variant, which offers higher capacity per dollar.
NOT a PCIe 4.0 or PCIe 5.0 drive — the CM5 family is PCIe 3.0 x4; PCIe 4.0 is the CM6 successor and PCIe 5.0 is the CM7.
NOT a consumer SSD — capacitor-backed PLP, TCG SSC, and DWPD-class endurance target 24/7 enterprise duty cycles.
Compatibility
The Kioxia CM5-V SDFMC06GEA01 drops into any server or storage chassis that exposes a U.2 (SFF-8639) NVMe-capable bay — for example, Dell PowerEdge R740xd / R7525, HPE ProLiant DL380 Gen10 with the NVMe-enabled backplane, Supermicro Ultra and BigTwin NVMe slots, and Lenovo ThinkSystem SR650 NVMe configurations. Use a U.2 host bus adapter or a tri-mode HBA (Broadcom / LSI) when bridging to a standard PCIe slot. Operating systems with native NVMe 1.3 support — Linux kernel 4.x and newer, VMware ESXi 6.5 and newer, Windows Server 2016 and newer — recognise the drive out of the box. Standard Kioxia / Toshiba CM5 firmware update utilities apply.
FAQ
Is SDFMC06GEA01 the same drive as KCM51VUG800G?
Yes. SDFMC06GEA01 is the OEM factory part number and KCM51VUG800G is the marketing SKU for the same 800 GB CM5-V U.2 drive.
Is the Kioxia CM5-V the same as the Toshiba CM5-V?
Yes. Toshiba Memory Corporation rebranded to Kioxia in October 2019; the CM5-V product, firmware, and warranty lineage are identical.
What is the difference between CM5-V and CM5-R?
The CM5-V is the write-intensive variant rated at ~3 DWPD with capacities up to 3.2 TB. The CM5-R is the read-intensive variant rated at ~1 DWPD with higher top capacities (up to 7.68 TB) at a lower price per gigabyte. Choose CM5-V for OLTP, journaling, and write-cache tiers; choose CM5-R for read caches, CDN nodes, and content libraries.
Will this drive work in a SATA backplane?
No. The CM5-V is a native NVMe device using the U.2 (SFF-8639) connector and PCIe 3.0 x4 lanes. It requires a U.2 NVMe-capable bay or a U.2-to-PCIe adapter; it will not be detected in a SATA or SAS-only slot.
What is the warranty status on a refurbished CM5-V from T.E.S?
Each refurbished unit ships with the T.E.S IT-SOLUTIONS test-and-verify warranty. SMART data, remaining endurance percentage, and full I/O functionality are validated before dispatch. Contact T.E.S for the exact warranty term applied to your order.
