Product overview
The Water Panther WP Expanse 10TB (WESA5SLC0100D) belongs to the Expanse SAN HDD family; the series datasheet is dated July 2022. It’s a 3.5-inch enterprise hard drive using SATA 6 Gb/s, 512e sectors, CMR recording, 7200 RPM, and a 256 MB cache, with ECC and non‑volatile write‑cache power‑loss protection documented for the line. Discontinuation status for this exact SKU is unconfirmed.
Positioned in the workstation tier, it exists to provide high‑duty, 24/7 bulk capacity for arrays where integrity and compatibility matter. Expect ~240 MB/s class sequential throughput typical of 10 TB 7200‑RPM CMR drives. Good fits include NAS/RAID mass storage and cold game libraries.
Unique: this SKU’s code indicates Legacy Pin‑3 power (no SATA power‑disable), improving compatibility with consumer PSUs and older backplanes.
