Capacity and interface
This 160 GB desktop drive uses a SATA 3.0 Gb/s interface and spins at 7200 RPM with an 8 MB cache. It suits builders who need a basic mechanical drive for legacy systems or secondary storage. Buyers who want more storage or solid-state speed will need a different product.
Thermals and power
The 3-D Defense System and 63 Gs operating shock rating protect the mechanism during normal desktop use. Average latency is 4.16 ms. No acoustic or power-draw figures are supplied, so specific thermal or noise expectations cannot be stated.
Bundled impact
The drive ships as a bare unit without cables, mounting brackets or software utilities. Installation therefore requires a separate SATA data cable, power connector and 3.5" bay hardware. The five-year limited warranty covers the drive itself only.

Questions about this item
How do I install this 3.5" SATA drive and what step is often missed?
Mount the drive in a 3.5" bay, connect the SATA data and power cables, then enable the SATA port in BIOS so the 160GB volume appears.
What maintenance or replacement will this BarraCuda 7200.9 need over time?
No scheduled maintenance is required; the 8MB cache and 3-D Defense System protect the platters, so replacement only occurs if the drive fails.
Which limit appears first during sustained use on this 7200 RPM model?
The SATA 3.0Gb/s interface caps sustained throughput before the 7200 RPM platters reach their maximum transfer rate.
