The 1TB WD Blue 3D SSD (WDS100T2B0A) Review

The 1TB WD Blue 3D NAND SSD IO Meter Benchmark Results

IO Meter

We compared the 1TB WD Blue 3D NAND SSD (Price Check) against the 1TB WD Blue SSD. If you wish to see how the SanDisk Ultra 3D SSD compares to other solid state drives, take a look at our Solid State Drive Performance Comparison Guide, which we will be updating shortly.

 

Throughput (Random Access)

512 KB Read 371.71 MB/s 239.84 MB/s + 55.0%
512 KB Write 488.55 MB/s 257.09 MB/s + 90.0%
4 KB Read 32.48 MB/s 24.93 MB/s + 30.3%
4 KB Write 75.94 MB/s 53.31 MB/s + 42.4%

The small random reads and writes are the most important tests for applications that make a lot of random accesses, so these would be key performance indicators for SSDs that are often used as boot drives.

The 1TB WD Blue 3D NAND SSD (Price Check) did incredibly well in this test, solidly beating the 1TB WD Blue SSD. Thanks to its built-in nCache 2.0 technology, it delivered almost twice the large random write performance of the 1TB WD Blue SSD!

 

Random Access Time

Test 1 TB WD Blue 3D NAND SSD 1 TB WD Blue SSD Difference
512 KB Read 1.41 ms 2.19 ms – 35.5%
512 KB Write 1.07 ms 2.04 ms – 47.4%
4 KB Read 0.13 ms 0.17 ms – 25.1%
4 KB Write 0.05 ms 0.08 ms – 29.8%

The random write performance of the 1TB WD Blue 3D NAND SSD (Price Check) was truly stellar, in comparison to the 1TB WD Blue SSD.

 

Random CPU Utilization

Test 1 TB WD Blue 3D NAND SSD 1 TB WD Blue SSD Difference
512 KB Read 29.50 % 7.16 % + 312.0%
512 KB Write 30.12 % 7.31 % + 312.3%
4 KB Read 32.53 % 9.94 % + 227.2%
4 KB Write 35.72 % 11.91 % + 199.9%

The only downside – the 1TB WD Blue 3D NAND SSD (Price Check) uses up a lot more CPU performance than the 1TB WD Blue SSD. About 3X more CPU performance, on average!

 

IO Meter (Sequential Accesses)

We compared the 1TB WD Blue 3D NAND SSD (Price Check) against the 1TB WD Blue SSD. If you wish to see how the SanDisk Ultra 3D SSD compares to other solid state drives, take a look at our Solid State Drive Performance Comparison Guide, which we will be updating shortly.

 

Sequential Throughput

Test 1 TB WD Blue 3D NAND SSD 1 TB WD Blue SSD Difference
512 KB Read 510.62 MB/s 250.14 MB/s + 104.1%
512 KB Write 494.55 MB/s 255.54 MB/s + 93.5%
4 KB Read 84.74 MB/s 63.35 MB/s + 33.8%
4 KB Write 75.98 MB/s 59.15 MB/s + 28.5%

The sequential read and write performance indicators determine how fast you can copy and move files. This is also important in determining how fast you can launch an application or game.

The 1TB WD Blue 3D NAND SSD (Price Check) did marvellously in this test, coming in twice as fast as the 1TB WD Blue SSD in large, sequential reads and writes.  It also had a large boost in small sequential read and write performance.

4 KB Read 36.38 % 15.93 % + 128.4%
4 KB Write 35.69 % 15.42 % + 131.5%

Again, the 1TB WD Blue 3D NAND SSD (Price Check) took up a significant amount of CPU processing power.
