Today we are comparing the PhotoFast G-Monster - PROMISE PCIe SSD to other recent solid state drives that we have tested.

The G-Monster - PROMISE PCIe SSD uses a Promise EX6850 RAID controller. You can see the controllers information in the image above.

There are four 32GB solid state drives inside running in a RAID 0 array. I left all of the controller settings as they ship from the factory.

 

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.

ATTO gives us all kinds of information this time around. The most obvious comes in the middle of the graph where we see the RAID controller's cache really helping out quite a bit with the write speeds. This is a reversal of what we would normally see. With most solid state drives the read speed is quite a bit faster than the write in this area.

 

ATTO is used by many companies to come up with a product's advertised speeds, but PhotoFast must have either used a different program or a model with larger drives, because we only achieved right around 530 MB/s for both read and write speeds. Let's move on so we can get to some real performance numbers.
