wow there very old ,do yourself a favor and get the LATEST intel ICHR10 driver 9.6 driver!
yes man i know its very old drive , but it was the latest drive when i install my OS
I don't know if i can upgrade to 9.6 driver without format my system ?

Intel recommends choosing RAID mode on their motherboards (which also enables AHCI)
So. my hard drives benefit from AHCI when i use raid0, nice


Unfortunately, it is not possible to trim drives that are setup and used with RAID , but i think Intel release TRIM for RAID
Thankfully, Intel has solved the problem with the release of a TRIM-compatible driver which finally brings the technology to SSDs in RAID arrays
