ATTO Disk Benchmark

In our ATTO Disk Benchmark test, the WD Blue 1TB SSD delivers very consistent performance between 128KB and 64MB file transfers, making this drive particularly useful for workload environments where users need to consistently transfer large files such as media, compressed file formats and databases, to name a few scenarios.

The drive tops out at 559MB/s read speeds for 2MB files and 534MB/s write speeds for 256KB files, both of which are above the rated 545MB/s sequential read and 525MB/s sequential write specs. The drive still does not quite approach the 600MB/s limitation of the SATA III interface, though we have yet to see any TLC NAND drive capable of doing this for now. The M.2 version of this drive is rated at the same speeds and also uses the SATA III interface, so there should be little to no performance difference between the two form factors in regards to SATA 6Gbps standard limitations.
