The WD Blue SSD is built on a TLC (triple-layer-cell) technology. It means, it writes three bits of data to one cell. It also has SLC (single-layer-cell) cache technology to boost performance. It also consumes less energy.

Like other SSD’s, it is also compact to take less space. It is lightweight and good in look. It comes with the plastic build. It has the brand logo and model number written on it and blue color represents the series. It also has aluminum base.

WD Blue does not offer encryption but it offers high endurance rating. The 250GB SSD allows you to high endurance rating. You will be able to write up to 100TB data over the lifecycle of this SSD. If you see it closely, it will last for 6 years if you write 50GB daily. Samsung 850 Evo is rated for 75 TB data write.

Western Digital also offers a software SSD Dashboard that lets you monitor your drive’s health. It also gives you detailed performance analysis. You can even sign up for email or SMS alerts when the temperature or health cross normal parameters.

I tested this drive with CrystalDiskMark. Results were good and it recorded 556.7MBps sequential reads and 527.7MBps sequential writes. The random read and write speeds were around 297MBps and 317.7MBps.

Samsung is the leader in SSD and it looks like WD Blue is offering similar kind of read-write speed.

In the Indian market, WD Blue 250GB SSD is available for around Rs. 6500. If you compare the pricing with Samsung 850 EVO 250GB, you get the difference of around Rs. 2000 because Samsung is selling 850 EVO 250GB for around Rs. 8500. It gives WD Blue an advantage. Here, you should also consider that Samsung is offering 5 years warranty while WD Blue comes with just 3 years warranty.


WD Blue is a good option for mid range PC. It performs well with good rear/write speed and comes for the competitive price. If you are on limited budget, this SSD will help you in building your PC. It looks to be SanDisk X400, but WD has re-tuned the firmware to offer better write endurance rating. This is the main highlight of the SSD. WD Blue is designed for users having an entry-level system and looking to update their traditional 7200 RPM hard drive for better performance.
