Capacity and interface

This Western Digital Scorpio Blue drive provides 80GB of storage over a SATA 1.5Gb/s interface. The 2.5-inch form factor fits standard laptop bays. It suits users replacing an original drive in an older notebook or adding modest capacity to a legacy system.

Thermals noise and power

Spinning at 5400 RPM, the drive runs quietly thanks to WhisperDrive technology with SoftSeek algorithms. Average latency is 4.2ms and average seek time is 12ms. The low rotational speed helps keep heat and acoustic output minimal during normal laptop operation.

Deciding specification

The SATA 1.5Gb/s interface is the single specification that determines compatibility. Systems requiring a faster SATA revision or a different physical interface cannot use this drive. Buyers needing higher throughput or larger capacity should verify their host controller supports this generation.

Questions about this item

How do I install the WD800BEVS in my laptop, and what step is often missed?

Slide the 2.5" drive into the SATA bay, secure it with the caddy screws, and connect the 7-pin data and power cables; the step people miss is ensuring the SATA 1.5Gb/s link negotiates at 1.5 Gb/s rather than falling back to a slower mode.

What maintenance or replacement will the Scorpio Blue need later?

No routine maintenance is required; the 5400 RPM mechanism and 8 MB cache are sealed, so replacement only occurs if the drive fails or you need more than 80 GB capacity.

What limit appears first during sustained use of this 80 GB drive?

The 5400 RPM spindle and SATA 1.5Gb/s interface cap sequential throughput, so sustained transfers hit the interface ceiling before the 12 ms seek time or 4.2 ms latency become bottlenecks.
