Horrible SSD Raid 0 Performance

So to sum up the issue. New Mobo & CPU, Went from a Core i3 with an h57 chip set to a new Phenom II x6 1055t with the MSI 890gxm board. On the old system I was lacking in CPU horse power & with fry's Anniversary sale I couldn't pass up the change (225 for the pair).

I have a Pair of Intel x18m 80gb in raid 0 (gen 1 drives). They were performing awesome before, very very snappy & pulled a 7.8 on the WEI score. Now nothing hard drive intensive is anything other then slow & they pull a whopping 5.9 on the wei score. At 1st install I had them setup at the default 64k & then resetp using 128k. But no change.

Any insight would be appreciated.
 
Did you reserve 25% space on the RAID0 volume, or did you use up all space?

In that case, you've probably fragmented the SSD all over. I would suggest a secure erase on both SSDs, recreate the RAID, then install Windows 7 and create a single partition that is smaller than the full capacity. So with 160GB/149GiB with 2x80GB in RAID0 you would make a 115GiB partition, leaving the rest unused.

This is the cost of not having trim and keeping your SSDs fast and have a much longer lifespan as well. It would require you to backup anything currently on the SSD RAID0, though.

Actually I partitioned it short 10gb the 2nd time around.. This was not done on the old system that performed great. the Drives were wiped & they are not old enough to be a issue where trim would even potentially be effecting them.
 
Prove it: show us the benchmarks.

That would enable us to judge whether you SSD has degraded in performance.

You should use:
- CrystalDiskMark (latest version)
- AS SSD (latest version)
