Desktop Test System
Lenovo W530 - Mobile Workstation
We use two systems for SSD testing. The desktop runs a majority of the tests and the Lenovo W530 runs the notebook power tests as well as the real-world file transfer benchmark.
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.
The ATTO results show the mismatched performance of the 128GB M5 Pro.
We achieved nearly 547MB/s read, but only 334MB/s write performance at QD4. Other manufacturers claim higher write performance on their 128GB capacity size drives, and since ATTO is the standard for making marketing statements, it's fair to do so. Maximum performance is one thing, but the Plextor performs better in real world conditions than what these numbers lead us to believe.
