WD Blue 250 GB SSD with 3D NAND Reviewed

Since the acquisition of SanDisk, Western Digital has been offering SSDs in its own portfolio. With the WD Blue Western Digital wants to offer an SSD with the flash memory 3D NAND for the normal user. This test will show whether the SSD can stand out against the competition.


The SSD comes without physical accessories. However, various software can be obtained from the WD website. On the one hand the program “WD SSD-Dashboard” is offered, which can display the available capacity, the operating temperature and the SMART attributes. On the other hand, “Acronis® True Image™ WD Edition” can be downloaded.

Technical Data of the WD Blue 250 GB SSD

The WD Blue is available in four different memory sizes and in a 2.5-inch or M.2 2280 form factor. In any case, SATA III 6 Gbit/s is used as the interface. Technically, the WD Blue is identical to the SanDisk Ultra 3D.

Test System

All tests are performed with the following hardware:

Benchmark Results

AS SSD Benchmark

AS SSD Compression Benchmark

AS SSD Copy Benchmark

CrystalDisk Benchmark

ATTO Disk Benchmark

HD Tune

Access Times

Everyday Experience

After formatting under Windows, the WD Blue has 232 GB of usable storage space.

WD Blue – Space

As the benchmark tests show, the SSD is very fast in every situation and is limited in some places by the SATA interface. The 250 GB version of the WD Blue tested here uses a 6 GB cache. If this cache is full, the write speed of the SSD decreases.

WD Blue – Copy test

In our test case an approx. 20 GB zip file was copied to the WD Blue. After 6 GB the write rate drops to approx. 200 MB/s.

Result of the WD Blue 250 GB SSD Review

The WD Blue with 250 GB tested here is a very good SATA SSD. The SSD’s long stated durability of 100 TB as well as its convincing write and read rate speak for themselves. Only the maximum transfer rate of the SATA port and the cache limit the SSD.

However, the price of the WD Blue is unfortunately quite high in relation to the strong competition like Samsung and Crucial. In order to be able to stand up to them, the price of WD Blue would have to be adjusted.

Value for Money

The WD Blue is a fast and expensive SATA SSD that performs very well in the test. Technically, only the write speed after the cache can be improved.
