WD My Cloud EX2100 – Performance
For our review we received an EX2100 pre-configured with two 4TB WD Red drives, which are WD’s NAS-specific drives that include particular optimisations for low-power usage and error-recovery in a NAS environment.
The EX2100 is a significant step up from WD’s previous efforts with the EX2 and EX4. In our large file (4.27GB) read and write tests it achieved 105.4MB/sec read and 105.7MB/sec write, which compares well to other dual-bay NAS offerings such as the Synology DiskStation DS215j. It also obliterates the 100MB/sec read and 40MB/sec write of the older EX2 unit.
This impressive performance continues when it comes to the more challenging test of transferring a number of small files (1,460 document and image files totalling 827MB) back and forth. It returned figures of 44.4MB/sec read and 34.5MB/sec write, which is comfortably ahead of the Synology DiskStation DS215j.
When you throw a really challenging random read/write test with tiny file sizes (CrystalDiskMark’s 4K test), performance does drop dramatically – 0.6MB/sec read and 1.7MB/sec write – but that’s an unrealistic test for the sort of use a NAS is likely to face.
Should I buy the WD EX2100?
The WD EX2100 is a pretty solid all-round performer. It will easily be up to the task of delivering files at a rapid pace to home and small-business users.
WD hasn’t slipped up when it comes to the overall user experience either. It’s a cinch to set up and use, and has plenty of support for useful network apps. Plus, if you sign up for a My Cloud account, it can give you access to your files the world over.
Crucially, the WD EX2100 is priced reasonably. At around £180 unpopulated and £330 with 4TB preinstalled (2 x 2TB drives), it’s certainly competitive with other leading brands.
However, it does still trail the Synology DiskStation DS215j, which starts at only £130 and is generally around £60 cheaper across the board. However, the EX2100 has a better drive system, includes USB 3.0, dual-Ethernet and a button-release for USB hard drives. Overall, it’s a far more capable unit.

The WD EX2100 is the ideal 2-bay NAS for home and small-business users: it’s well built, feature-packed and performs well. It’s a little more expensive than the most basic 2-bay units – but it easily justifies its cost.
