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.
Western Digital claims a read/write speed of 200MB/s, but they are shorting themselves. In our testing we nearly achieved 230MB/s read and around 210MB/s write speeds.
It's always nice to see better performance than what's listed on the spec sheet.
