Positioned in our workstation tier (enterprise/high‑TBW), it exists to maximize storage density and reliability per dollar and per watt in multi‑bay arrays. With SATA 6 Gb/s, 3.5‑inch form factor, 512 MB cache, and about 267 MB/s typical sustained throughput, it suits mass storage pools, large game libraries, and sequential media workflows/scratch in NAS or servers; use SSDs for OS/apps. Notably, the “ALE6L4” variant uses a legacy Pin‑3 layout (no 3.3 V Power‑Disable), improving compatibility with many consumer PSUs/enclosures.
