WD Blue 1TB Desktop Hard Drive
1TB CMRSATA 6 Gb/s5400 RPM64 MB cacheQuiet and low power
The WD Blue 1TB (part number WD10EARZ) is a 3.5-inch CMR desktop hard drive running at 5400 RPM with a 64 MB cache and sustained transfers of up to 180 MB/s over SATA 6 Gb/s. It is the entry point of the Western Digital desktop range: quiet, cool and inexpensive, intended as secondary storage or a straightforward replacement disk in a home or office PC. Typically in stock with fast delivery across Cyprus.
Before you buy: this is a bare 3.5-inch internal drive with no mounting screws, SATA cable or enclosure in the box. It needs a desktop chassis bay with a SATA 6 Gb/s port and a SATA power connector, and it will not fit a laptop. Note the part number carefully. In the WD Blue range the EARZ and EZAX suffixes are CMR while the very similar EZAZ suffix is SMR, and SMR drives slow considerably during sustained rewrites. This drive is the CMR one.
Best For
✓ Replacement disk in an older desktop
A straightforward 3.5-inch SATA drive for a machine whose original hard drive has failed or filled up.
✓ Secondary document and media storage
Cheap capacity alongside an SSD that holds the operating system.
✓ Low-noise builds
21 dBA idle is about as quiet as a mechanical drive gets.
✓ Low-power always-on machines
4.0 W during read and write and 2.4 W idle, easy on a small power supply.
Key Features
CMR, not SMR
Western Digital lists WD10EARZ as conventional magnetic recording, unlike the SMR drives that share the WD Blue family.
Very quiet
21 dBA idle and 26 dBA seek, the quietest figures in the WD Blue desktop range.
Low power draw
4.0 W during read and write, 2.4 W idle and 0.3 W in standby.
64 MB cache
A modest buffer sized to the capacity, adequate for general desktop file work.
Advanced Format 512e
Standard modern sector formatting, compatible with current Windows, macOS and Linux installations.
300,000 load/unload cycles
Rated head park cycles for desktop-class duty.

Frequently Asked Questions
Is the WD10EARZ CMR or SMR?
CMR. Western Digital lists this exact part number as conventional magnetic recording in its published data sheet. This matters because some drives in the same family use SMR, which slows badly on sustained rewrites, and the part number suffix is the only way to tell them apart.
Why buy a 1TB hard drive rather than an SSD?
For an operating system an SSD is far better. A 1TB mechanical drive still makes sense as cheap secondary storage, as a replacement for a failed drive in an older machine, or as a local backup target where cost per gigabyte matters more than speed.
Is the WD10EARZ CMR or SMR?
CMR. The EARZ suffix denotes conventional magnetic recording in the WD Blue family, while the EZAZ suffix on other capacities denotes SMR. Western Digital publishes this distinction in its WD Blue product brief.
What do I need to know before buying the WD10EARZ?
It ships as a bare internal drive with no cables, screws or enclosure. Western Digital does not publish a workload or MTBF rating for this consumer line, so if you need those figures for a server or NAS specification, look at WD Red Plus, WD Red Pro or WD Gold instead.
Singular Expert Insight
At 1TB the honest question is whether a hard drive is the right tool at all, since an SSD of the same capacity will transform how a machine feels. Where this drive earns its place is as a second disk or a like-for-like replacement in an older desktop, and the fact that it is CMR rather than SMR is the reason to prefer this part number over its cheaper siblings. Browse our desktop and laptop hard drives or, if the drive is destined for a NAS instead, our NAS hard drives.
Buyer's Guide
Buy this if
You need cheap secondary capacity or a straight replacement disk in an older desktop, and you want CMR rather than SMR.
Skip if
This will be the system drive. An SSD of the same capacity costs little more and makes the machine dramatically faster.
Also consider
An internal SSD for the operating system, WD_BLACK for a faster desktop drive, or WD Red Plus if the drive is going into a NAS.
