160 GB desktop hard drive
This Western Digital Blue WD1600AAJS is a 160 GB, 7200 RPM desktop drive with 8 MB cache and a SATA 3.0 Gb/s interface. The 3.5 inch form factor fits standard drive bays in older towers or secondary storage arrays. It is sold as a bare drive without cables or brackets. Average seek time is 8.9 ms and average latency is 4.2 ms.
Who this suits and who it does not
This drive suits users needing a direct replacement for a legacy SATA boot or data drive in an older desktop or DVR. It is not for builders who need higher capacity, faster throughput, or a modern SATA 6 Gb/s interface for current platforms.
Deciding specification — SATA 3.0 Gb/s interface
The SATA 3.0 Gb/s interface is the single specification that decides compatibility. Verify that the host controller or motherboard supports this generation; a SATA 6 Gb/s port will negotiate down, but an older SATA 1.5 Gb/s port will limit throughput.

Questions about this item
How do I install the WD1600AAJS 3.5" SATA 3.0Gb/s drive and which step do people often miss?
Mount the 3.5" drive in a desktop bay, connect a SATA data cable to the motherboard and a SATA power connector from the PSU; the step often missed is setting the BIOS to AHCI mode for the SATA 3.0Gb/s interface.
What maintenance or replacement will the WD1600AAJS 7200 RPM 8MB cache drive need later?
No routine maintenance is required; the mechanical 7200 RPM motor and bearings will eventually wear, so plan to replace the drive when SMART reallocated-sector counts rise or seek times exceed the 8.9ms spec.
What limit appears first on the WD1600AAJS 160GB drive under sustained use?
The 8MB cache fills quickly during long sequential writes, forcing the 7200 RPM platters to throttle to the native 4.2ms latency and 8.9ms seek time, which becomes the throughput bottleneck.
