SanDisk Extreme II 120GB SSD Review - Benchmarks - Test System Setup and ATTO Baseline Performance

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.




Our ATTO test shows a maximum read speed of 553MB/s and a maximum write speed of right around 340MB/s. Even though we use a different method than SanDisk, our numbers are in line with their marketing numbers.


The 340 MB/s write number may seem low, but it's important to remember we are working with next-gen flash and not 24/25nm. To put Extreme II's write performance into perspective, the Crucial M500 with the same controller, different firmware and different flash only managed to product 140MB/s write speed in ATTO.
