WD Ultrastar SN200 960GB U.2 NVMe Enterprise SSD — 54-91-60013-1024G

Technical Identity
The Western Digital Ultrastar SN200 960GB (P/N 54-91-60013-1024G) is a read-intensive enterprise NVMe solid-state drive in a 2.5-inch U.2 (SFF-8639) form factor, operating over a PCIe Gen3 x4 interface with NVMe 1.2 protocol support. This is a data center class SSD from Western Digital's (originally HGST) Ultrastar NVMe product line, engineered for read-dominant workloads in enterprise servers, hyperconverged nodes, and virtualization hosts. Condition: Refurbished — Tested & Certified by T.E.S IT-SOLUTIONS.

What This Is NOT

NOT a SATA drive — will not be detected by any SATA controller or SATA-only backplane.
NOT a SAS drive — incompatible with SAS HBAs and SAS RAID controllers.
NOT an M.2 SSD — uses 2.5-inch U.2 (SFF-8639), not M.2 2280 or 22110.
NOT a write-intensive drive — 1 DWPD only; for write-heavy or mixed-use workloads see the Ultrastar SN640 (1 DWPD mixed) or SN840 (3 DWPD).
NOT a consumer SSD — this is an enterprise data center drive with PLP, continuous-duty thermals, and full-time error correction.
NOT current generation — direct successor is the Ultrastar DC SN640; current-gen Western Digital replacements are the DC SN650 and DC SN655.


Compatibility
The Ultrastar SN200 requires a U.2 (SFF-8639) NVMe-capable backplane or a PCIe-to-U.2 adapter card (e.g., Supermicro AOC-SLG3-2E4, Dell NVMe enablement kit, HPE NVMe riser). Verified-compatible enterprise platforms include Dell PowerEdge R640 / R740xd / R7525 with NVMe backplane, HPE ProLiant DL360 / DL380 Gen10 NVMe cages, Supermicro X11 / X12 NVMe chassis, and Lenovo ThinkSystem SR630 / SR650 NVMe configurations. The drive negotiates at PCIe Gen3 x4; it will downshift in Gen2 slots with reduced throughput. Verify 15 mm z-height clearance in your drive tray — 7 mm-only trays will not accept this drive. Native NVMe drivers are present in Linux kernel 3.10+, Windows Server 2012 R2+, VMware ESXi 6.0+, and FreeBSD 10+. For airflow-constrained chassis, confirm that the bay can sustain the drive's ~25 W peak power draw under sustained workload.

FAQ
What is the endurance and throughput of the Ultrastar SN200 960GB (54-91-60013-1024G)?
The Western Digital Ultrastar SN200 960GB (P/N 54-91-60013-1024G) has an endurance rating of 1 DWPD (Drive Write Per Day), approximately 1.75 PBW total. It delivers up to ~3,000 MB/s sequential read and ~1,150 MB/s sequential write over PCIe Gen3 x4 NVMe 1.2. Random I/O reaches up to ~300,000 IOPS read and ~80,000 IOPS write (4K). This makes it suited for read-intensive data center workloads.

Can the Ultrastar SN200 (54-91-60013-1024G) be used in a SATA drive bay?
No. The Ultrastar SN200 (54-91-60013-1024G) uses NVMe over PCIe Gen3 x4 with a U.2 (SFF-8639) connector. It requires a U.2 NVMe-capable server backplane or a PCIe-to-U.2 adapter. It will not be detected in SATA-only or SAS-only drive bays. The 15mm z-height should be verified against your drive tray clearance.
