WD Red SA500 1TB 2.5" SATA SSD

The SanDisk WDS100T1R0A-68A4W0 is a Western Digital Red SA500 internal solid-state drive built for NAS caching. It uses 3D NAND flash and a SATA III 6 Gb/s interface in a 2.5-inch, 7mm form factor. Sequential reads reach up to 560 MBps and writes up to 530 MBps.

Suits NAS caching and mixed read/write workloads

This drive targets home and business NAS owners who need a cache tier for frequently accessed files, OLTP databases, multi-user environments or 4K and 8K video editing. Its 2M-hour MTTF and high endurance rating support 24/7 operation. Systems limited to a single drive bay or requiring boot-only storage should consider a larger-capacity model instead.

SATA III 6 Gb/s interface decides compatibility

The drive connects over a standard SATA III port and will not work in M.2 slots wired for PCIe only. Maximum 4KB random performance is 95,000 read IOPS and 85,000 write IOPS. Active power peaks at 3,750 mW during writes and 2,550 mW during reads, with idle slumber at 56 mW.

Questions about this item

Will the 560 MB/s sequential read speed stay constant during long NAS caching sessions?

Sustained throughput is limited by the SATA III 6 Gb/s interface and the drive's 560 MB/s read ceiling; thermal throttling may reduce speeds once the 70 °C operating limit is reached.

How much heat and power does the drive produce when it runs 24/7 in a NAS bay?

Active power peaks at 3,750 mW during writes and 2,550 mW during reads; idle slumber draws 56 mW and DEVSLP only 5–12 mW, so heat output stays modest inside a 0–70 °C rated enclosure.

Does my NAS need a specific drive bay or caddy to fit this 2.5-inch SATA SSD?

The drive uses a standard 2.5-inch 7 mm SATA form factor, so any NAS bay or caddy that accepts 2.5-inch SATA drives will work without extra adapters.
