Well the drives certainly don't feel slow, but the benches tell me there is an issue somewhere. Fresh install of Win7 Premium after a secure erase on both drives. System specs in the sig. What is could be causing this and how would I go about fixing it?

To me this result is expected / good. Its pretty much double the single drive speed.

I suppose I was looking to see something higher than the advertised max sequential write speed of 500 MB/s.
 
You are absolutely right. I knew the Sandforce drives didn't play well with non-compressible, I just didn't realize how bad it really was, or that as ssd/crystaldisk benched with so much non-compressible data.

Now I know, and knowing is half the somethingorother...

...there is also the issue of sandforce controllers and writing large amounts of data (ie. benchmarking), which is kind of a catch 22. not sure how RAID /TRIM and all figure into that.

I did not know that about the large amounts of data either.

To what do you refer to with RAID/TRIM?
