WD Blue 10TB CMR desktop drive

The WD Blue WD100EAGZ is a 3.5-inch internal hard drive built for everyday desktop use. It offers 10TB of storage on a SATA 6.0Gb/s interface with a 7200 RPM spindle speed and 512MB cache. Conventional magnetic recording (CMR) provides consistent performance for general workloads.

Suits office PCs and bulk storage.

This drive fits standard desktop bays and works well for office applications, web browsing and expanding local file libraries. The included Acronis cloning software simplifies migration from an older drive. Systems that lack a SATA data and power connection cannot use this drive.

10TB CMR capacity on SATA 6.0Gb/s

The single specification that decides fit is the 10TB CMR capacity delivered over a SATA 6.0Gb/s interface. Buyers needing a different capacity, a different recording technology or a non-SATA interface should select another model.

Questions about this item

Will this 3.5-inch, 26.10 mm high drive fit my desktop's standard drive bay?

Yes — the drive measures 147.00 mm long, 101.60 mm wide and 26.10 mm high, matching the standard 3.5-inch desktop form factor used in most PC cases.

What is the common mistake when connecting this SATA 6.0Gb/s drive to the motherboard?

Using a SATA 3.0Gb/s port or an old cable limits the drive to half its rated interface speed; plug it into a native 6.0Gb/s port with a good-quality cable.

Does the 512 MB cache or the CMR recording technology require any periodic maintenance?

No scheduled maintenance is needed; the NoTouch Ramp Load technology keeps the heads off the platters during idle and power cycles, reducing wear over the drive's life.
