First OCZ Core Series SSD results!

My controller card is the ARC-1231ML

Yep, my guesses are correct then. The sequential read and write are almost only the cache speed. I did a try with my HDDs with crystal and where i test the scsi drives under my PERC 4e (250mb of cache), the speeds are over what they should be for the drives.

But the good thing is that a part of that speed is true in the real world, because the controller cache is indeed used in sequential reads.
See my test with 2x 15k scsi disks in raid0.
In your case because of the greater cache (i think 1gb) also the sequential writes are influenced.
