Overview
A mechanical disk with NoTouch ramp load technology defines this WD Blue internal drive, which adds bulk storage to a desktop PC over a SATA connection. Acronis True Image is listed among its additional features.
Large capacity makes this drive a bulk storage tier for documents, photos and backups. The spinning disk starts files with a delay, so it suits storage rather than running the operating system.
Who it's for
A desktop tower with a free drive bay and a spare SATA port, used for archives and media libraries. Laptop owners and anyone chasing fast boot times should look at other drive types.
Pros and cons
- Large bulk storage capacity
- SATA connection for desktop PCs
- NoTouch ramp load head design
- Acronis True Image software listed
- Mechanical disk with moving parts
- Slow rotational speed limits access time
- Too large for laptop bays
- Operating noise level not listed
Performance notes
Rotational speed and cache govern the feel. The platters spin at a modest rate, so random file access waits on the head moving across the disk, while large sequential copies run better than many small files. The SATA link has more bandwidth than a spinning disk can fill, and the listing credits the head design for gentler parking.
