We test all SSDs as our system (OS) disk filled 50% with data. This allows us to closely replicate a typical user scenario. When reading sequential data, the Spectrix S40G 1TB can do it faster than any Gen3 SSD we've ever tested. ADATA specs sequential read/write performance for the S40G as an empty secondary device using CDM set to QD64T1. We do not use that setting or test empty. For our testing, we run at defaults which is likely the reason we come up a bit short of the drive's factory spec of 3,000 MB/s seq. write.

Anvil's Storage Utilities


Anvil's is in our opinion the best synthetic test for evaluating overall performance. We consider overall read performance to be most important. In terms of overall read performance, the Spectrix S40G doesn't score as well as we hoped it would. That said, it's still plenty fast enough for most users and far better than anything SATA can offer. We also need to keep in mind that the XPG Spectrix S40G is designed to be visually dazzling above all else.


We don't place much importance on max IOPS, we are just showing what the drive can deliver while running in our test-state.
