I asked a related question elsewhere (Hardware?) and the one respondent much preferred IDE (for sata mode) for their SSD.
I considered IDE sata mode was a backward step initially. But driver updates wouldn't stop Windows device manager seeing the Sata HDD & DVD as Scsi. Generally not a problem but the odd program wouldn't see the drive:
- Seatools wouldn't see a Seagate sata HDD
- Hirens boot CD wouldn't see it.
Changed to Native IDE mode and windows sees HDD & DVD as ATA devices. Above programs now work fine.
What about speed? CrystalDiskMark benchmarked sequential reads better. Informal testing suggested better speed performance!
So that's why I changed.
