Moving files around and the transfer speed was slow, around 23-25MB. Normally they transfer between drives between 60-70 MB. I have antivirus turned off. I disabled defender. Checked to see if anything was funny in device manager, and all my sata drives are listed as SCSI drives. Isn't this unusual? I have AHCI enabled in bios, but it has been since I installed 7. I'm just wondering if it is common for sata to be listed as SCSI? Could this be why transfers are slow? everything else seems to be normal, except I've been TRYING to delete (without success) some weird service listings (file not found, although they point to normal windows services).
