Optimizing Corsair SSD Windows 7

0

I am currently having a Force Series™ GS 128GB SATA 3 SSD which is supposed to have the following specs:

Sequential Read Write 560 MB/s sequential read — 535 MB/s sequential write

But, instead, I'm only getting: (which is far less from what it should be doing)

enter image description here

I already tried to TRIM the SSD with the Corsair Toolbox
and also I have followed this optimizing guide which explains how to improve perfomance by disabling page-file on the SSD and turning off indexing.

Is there anything else I need to do to reach that speed mark?

The highest real-world benchmark speeds I've ever seen for this SSD are 496MB/s sequential read and 270MB/s sequential write. 467/214 seems about average, so you're just a bit under what other people are seeing. – David Schwartz – 2014-03-11T22:57:57.767

Your SSD uses a SandForce SF-2200 controller, which only gets the high write performance hwen using data which can be compressed fine. In normal usage the values are much lower (as you can see).

SandForce controllers also use a proprietary compression system to minimize the amount of data actually written to non-volatile memory (the "write amplification") which increases speed and lifetime for most data (known as "DuraWrite"). SandForce claims to have reduced write amplification to 0.5 on a typical workload. As a byproduct, data that cannot readily be compressed (for example random data, encrypted files or partitions, compressed files, or many common audio and video file formats) is slower to write.

So, there is nothing else to optimise in it then? – zurfyx – 2014-03-12T07:55:24.533

correct, there is nothing you can improve here. – magicandre1981 – 2014-03-12T19:25:09.373
