WD800BEVT 80 GB 2.5-inch SATA drive

The Western Digital WD800BEVT is a 2.5-inch internal hard drive with 80 GB capacity, 5400 RPM spindle speed and an 8 MB buffer. It connects via a SATA 3 Gb/s interface and is supplied in new condition. This drive suits older laptops, compact desktops or external enclosures that accept a 2.5-inch SATA device.

Fits 2.5-inch SATA bays and enclosures

The drive requires a standard 2.5-inch drive bay with a SATA data and power connection. Its 5400 RPM speed and 3 Gb/s link draw modest power, leaving headroom in tight thermal envelopes. The SATA interface keeps cabling simple and frees up PCIe or M.2 slots for other components.

80 GB capacity with 5400 RPM throughput

The 80 GB platter stores operating system files, documents and lightweight applications comfortably. Sequential transfers are limited by the 5400 RPM rotation and 3 Gb/s SATA ceiling, so large media libraries or modern game installs will exhaust space and speed quickly. Buyers needing more capacity or faster access should consider larger or higher-speed drives.

Questions about this item

How fast does the 5400 RPM platters and 8 MB cache handle sustained writes before the 3 Gb/s SATA link saturates?

The 5400 RPM rotation and 8 MB buffer feed data at mechanical-disk rates, so the 3 Gb/s SATA interface rarely becomes the bottleneck during long sequential writes.

What noise and heat should I expect when this 2.5" drive runs continuously in a laptop chassis?

At 5400 RPM the Scorpio Blue stays quiet and cool enough for typical notebook bays; no active cooling is required beyond the laptop's normal airflow.

Which SATA revision must my motherboard or caddy support for this WD800BEVT to operate?

The drive uses a standard 2.5" SATA 3 Gb/s connector, so any SATA I or SATA II port will work without adapters.
