Purpose-built enterprise drive
The Western Digital Caviar RE WD1600YS is a 160GB 3.5-inch internal hard drive built for 24x7 operation in servers and RAID arrays. It spins at 7200 RPM with a 16MB cache and connects via a SATA 3.0Gb/s interface. The drive targets system integrators and IT professionals who need proven reliability in high duty-cycle environments rather than maximum capacity.
Bare drive changes the setup
Supplied as a bare drive without cables, mounting screws or software, the WD1600YS requires the installer to provide a SATA data cable and a compatible power connector. The FlexPower connector accepts both legacy Molex and native SATA power plugs, simplifying power-supply compatibility. No bundled utilities or drivers are included; the drive relies on native operating-system support for SATA.
Straightforward mechanical install
Installation follows standard 3.5-inch drive bay procedures: secure the unit with four screws, attach the data and power cables, and configure the BIOS or RAID controller. The 4.2ms average latency and fluid dynamic bearing motor keep vibration low, but the bare packaging means no anti-static bag or rails are provided. Builders should verify that their chassis has a free 3.5-inch bay and that the RAID controller supports time-limited error recovery to avoid drive fallout.

Questions about this item
Will the 16MB cache need replacement later?
The 16MB cache is built into the drive and does not require separate replacement; the whole unit is serviced if it fails.
What limit appears first during continuous 24x7 operation?
The SATA 3.0Gb/s interface caps sustained transfer rates before the 7200 RPM platters reach their own ceiling.
How much noise and heat does the fluid dynamic bearing motor produce when running all day?
The fluid dynamic bearing motor reduces vibration and noise while the improved power controller keeps heat and power draw low during 24x7 use.
