ATTO Baseline Performance
Version and / or Patch Used: 2.34
ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.
Using ATTO to check the manufacturers claimed speeds, we see some off results. The AS602 performed quite a bit slower than all of our other SandForce SF-1200 based SSDs. The 277MB/s read is just a little slower than the 285MB/s that we are used to, but the write speed of 225MB/s is quite a bit slower than the 275MB/s we expect.
