Baseline Performance with ATTO





I started testing of the 12Tb IronWolf by running the drive through ATTO Disk Benchmark and recording the results in our charts. For comparison, I have the 10TB IronWolf from last years review in the charts too. Performance has improved on the bottom end quite a bit with the 12TB, especially in read operations taking off at 4K and maintaining a steady 225 MB/s read throughout.




Write performance takes off at 8K and maintains 225 MB/s through 8M.
