Crystal Disk Mark 6.0 is our third test. Just a bit of background information; higher capacity drives tend to perform a little better in these tests. The ability of a controller and flash memory to deliver high IOPS will provide huge benefits to the score as well. Looking at the sequential read and write results, this Western Digital Blue SN550 NVMe SSD 1TB was in the bottom half for most of these drives, though this should come to no surprise. The sequential numbers are still better than the preceding SN500 and both of the Crucial P1 drives, as we see the SN550 reach its peak read and write speed here. In the 4K tests, the SN550 stayed in a similar range as the P1 1TB numbers in both read and write. Finally, with a single queue and thread, the WD Blue SN550 was a bit behind for read speeds, though near the middle of the pack for write. These results are not too surprising considering the budget nature of this drive.
