SSD speed

[Mike57v]

Hi, what tools to use or how to find out what is slowing down SSD?

 

I have MB: GA-Z77-D3H and Kingston SSDNow v+200 120GB. They are connected through SATA 3 (this mother board has only two) and using SATA3 6GB cable (not that the cable matters too much). This should give reasonable read or write around 400+Mb from what I saw around or with similar systems.

 

Unfortunately, my seq is providing 200mb read and 100mb write.

 

Can you point me to right direction where the bottleneck can be?

What software are you using to test it with? Try running CrystalDiskMark and posting a screenshot of results here.

I have the same problem. It boots alot faster than my HDD, but has nearly the same write speeds.
