We test all SSDs as our system (OS) disk filled 50% with data. This allows us to closely replicate a typical user scenario. WD's specs sequential for the SN550 1TB at 2,400 MB/s read and 1,950 MB/s write. We had no issues meeting and exceeding factory sequential specs.
Looking at the random performance, we find the SN550 delivering a bit more than some of the big-name enthusiast favorites. Keep in mind this is a DRAMless SSD.

Overall, read performance is always our primary focus. Were it not for relatively low sequential performance, the SN550 would be near the top of our read chart. The good news here is sequential performance is the least important factor when it comes to delivering a tier-one user experience. We will see this fact demonstrated when we get to our new PCMark 10 storage testing.
We can't quite hit factory specs for max random performance. This is most certainly because we test as system disk 50% filled. We place zero importance on max random performance. We just show what we can attain in our user state.
