The 1TB WD Blue SSD (WDS100T1B0A) Review

Page 10 : ATTO Disk Benchmark Results, Our Verdict

ATTO Disk Benchmark

ATTO Disk Benchmark is a free benchmark that allows you to compare the performance of solid state drives using a variety of transfer sizes. It also allows us to determine if the SSD performs data compression to improve performance, and extend lifespan.


I/O Comparison

Results Compressible Data Non-Compressible Data
Minimum Maximum Minimum Maximum
Read Speed 11.3 MB/s 246.8 MB/s 11.3 MB/s 249.7 MB/s
Write Speed 10.4 MB/s 269.5 MB/s 10.6 MB/s 269.5 MB/s

The Marvell 88SS1074 controller does not perform any data compression, which is why the performance results are the same for both compressible and non-compressible data. The 1TB WD Blue SSD reached its peak transfer rate with a block size of 1 MB.


Multiple I/O Comparison

Results Compressible Data Non-Compressible Data
Minimum Maximum Minimum Maximum
Read Speed 26.6 MB/s 286 2 MB/s 26.6 MB/s 285.6 MB/s
Write Speed 24.5 MB/s 273.9 MB/s 24.8 MB/s 274.5 MB/s

With just 8 simultaneous transactions, the 1TB WD Blue SSD reached its peak transfer rate with a block size of 64 KB.


Our Verdict

The 1TB WD Blue SSD offers extremely quick random access times like other modern solid state drives. But it is no race car. Due to its 4-channel design, it was half as fast as comparable SSDs at transferring large files. On the other hand, it offers a tremendous amount of space at an affordable price point, and boasts enterprise-class endurance levels. So what does this mean for you, the user?


If you are looking for the absolute fastest SSD in the market, then the 1TB WD Blue SSD is not for you. You can find much faster SSDs in the market, albeit at much higher price points.

But if you are looking for a decent solid state drive with a large storage capacity, and don’t want to sell an arm and a leg for it, the 1TB WD Blue SSD is worth considering. More so if you want something that will last you for many years to come.

The 1TB WD Blue SSD works well as a boot drive, booting up the operating system and applications much faster than any hard disk drive can. It may be much slower than comparable SSDs in certain benchmarks but in real life, it will only mean the operating system and applications start up a bit slower. In fact, you are unlikely to notice any difference unless you compare two systems side-by-side.

The WD Blue SSD‘s large storage capacity is a great boon to laptop users who cannot add a second hard disk drive for more storage. It would obviate the need to use a portable hard disk drive for extra storage. It also allows for an intriguing possibility – install it into a USB enclosure and you have a spacious portable drive that is impervious to shock and vibration!
