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)
| Test | 1 TB WD Blue 3D NAND SSD | 1 TB WD Blue SSD | Difference |
| 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.
Sequential Access Time
| Test | 1 TB WD Blue 3D NAND SSD | 1 TB WD Blue SSD | Difference |
| 512 KB Read | 1.03 ms | 2.10 ms | – 51.2% |
| 512 KB Write | 1.06 ms | 2.05 ms | – 48.3% |
| 4 KB Read | 0.05 ms | 0.07 ms | – 26.7% |
| 4 KB Write | 0.05 ms | 0.07 ms | – 22.4% |
Sequential CPU Utilization
| Test | 1 TB WD Blue 3D NAND SSD | 1 TB WD Blue SSD | Difference |
| 512 KB Read | 29.61 % | 8.69 % | + 240.7% |
| 512 KB Write | 29.11 % | 5.76 % | + 405.4% |
| 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.
