You might wonder why we're testing two solid state drives in the one review? Well, it's because WD is being a little tricky with its marketing for these two products. The WD Blue 3D range of drives is aimed at resellers and system builders, while the SanDisk Ultra 3D drives are being marketed to...

Having arrived at the third generation of the BiCS 3D NAND, developed by Sandisk and Toshiba, WD thinks the time has come to base consumer products on the new technology. The performance of the WD Blue 3D and Sandisk Ultra 3D are on-par with the 3D NAND-based Micron SSDs and only slightly worse than...

We have been nothing but impressed by both the WD Blue 3D SSD and the SanDisk Ultra 3D in today's review. Bombarding these twins with benchmark after benchmark only helped to establish their rank as some of the best performing SATA 6Gb/s SSDs out.

In our benchmarks tests, we managed to get a maximum read speed of around 557.8 MB/sec and write speed of up to 520 MB/sec. This is very good, all thanks to the super fast Marvell 88SS1074 controller inside. If you've noticed lately, I've started to do a lot of videos, unboxings and vlogs.

1TB capacity; 3D NAND Technology; Very good performance; Fast Marvell 88SS1074 controller; Cheaper than the WD Blue 3D NAND SSD

1TB Drive from SanDisk – one could only dream of a 1TB SSD back in the past but now it seems that it is a reality but at quite a high cost but that's the price you pay to get high-speed fast storage, especially for notebook computers when you're working on the go.

aawsom thing to buy make my latop super fast

upgrading from old samsung ssd(great p&p for 4 years).

nice paperweight

shows up in bios- not device or disk man

I purchased this to replace an existing SSD and the speed improvement is clearly noticeable. In my opinion this is an excellent drive and worth consideration if you seek a 2.5 SSD.

No matter how ingenious the manufacturers' R&D departments might be, a SATA SSD can only go so fast: throughput limits mean that it's only going to get harder for a SATA-based SSD to innovate.

High write speeds; Good durability

Inconsistent in everyday use

This SSD uses SLC caching trickery to keep write speeds high, but don't expect industry-leading performance
