250GB NVMe cache drive for NAS

The SanDisk WDS250G1R0C is a 250GB internal SSD built for network-attached storage. It uses the M.2 2280 form factor and a PCI-Express 3.0 x4 interface. The drive targets small-to-medium business workloads such as virtualization, collaborative editing and multi-user databases.

Upgrade from SATA SSD caching

This NVMe SSD replaces a SATA cache device to deliver higher I/O performance and lower latency. Sequential reads reach up to 3100 MBps and writes up to 1600 MBps. Random reads hit 220000 IOPS and writes 180000 IOPS. The jump is worth it when your NAS serves many simultaneous users or runs latency-sensitive applications.

Fits M.2 2280 slots with PCIe 3.0 x4

The drive slots directly into a compatible M.2 2280 connector wired for PCI-Express 3.0 x4. Endurance is rated at 500TB written and MTTF at 1750000 hours. Idle power draw is 70 mW. Operating temperatures range from 0°C to 70°C, while storage temperatures span -55°C to 85°C.

Points forts

  • NVMe caching accelerates NAS responsiveness with up to 3100 MBps sequential read
  • High endurance sustains heavy workloads through 500 TBW and 1,750,000 hours MTTF
  • PCIe 3.0 x4 interface delivers up to 220,000 IOPS random read for multi-user tasks
  • Low 70 mW idle power reduces heat in always-on NAS enclosures
  • M.2 2280 form factor fits standard NAS slots for easy capacity scaling

Questions sur cet article

Does the M.2 2280 form factor fit my NAS slot?

The drive is an M.2 2280 module measuring 22.00 mm wide and 80.00 mm long, matching the standard slot found in compatible NAS devices.

How do I install the PCI-Express 3.0 x4 drive, and what step is often missed?

Align the notched edge with the M.2 key, insert the drive, then secure it with the retention screw; the missed step is forgetting that screw, which leaves the drive unseated.

When will the 500 TBW endurance rating require replacement?

The drive is rated for 500 terabytes written; replacement depends on your actual write volume, which the NAS SMART tools can track over time.
