i have a HDD with my OS on it, and an SSD for my second drive that only holds data. in windows 7 64-bit, it doesn't offer to set-up that second drive in AHCI mode, but only NTFS. is AHCI only available for a main drive SSD?

i checked the BIOS settings and don't see it there either.

thanks.

AHCI or IDE (compatability mode) is for the controller not on a drive by drive basis.

AHCI is a data transfer mode for the drive controller setting
NTFS is how the drive partition is set up. for example, FAT16, FAT32, NTFS, GPT

They are totally different things.

Hope I explained it clearly enough

thanks.

i'm having trouble getting SATA III speeds with my SSD SATA III (Patriot Memory Pyro, 60GB). i have all the drivers for chipset and motherboard. i have a SATA III cable. the SSD is nfilled about 88%. my motherboard is rated for SATA III (Asus M5A88-M). i used HD TubneUp Pro and CrystalDiskMark for testing. 1 said the read speed is 125MB/s, the other 140MB/s.

any idea what is going wrong?

thanks.
