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

SanDisk Extreme II 120GB SSD Review
We're starting our SanDisk Extreme II review coverage with the 120GB capacity size. Later today we'll publish reviews of the 240GB and 480GB, but the 120GB size has more talking points and shows why SanDisk now has the most advanced NAND on the market today. (NASDAQ:SNDK)

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.
