Your ATTO numbers look pretty close to what OCZ list on their specifications for a SATA II drive. I won't worry too much, since you are now running in AHCI mode. Your drive seems fine to me.
Ahh, thanks alot for that :3
Is it worth upgrading mobo to Sata 3 for the extra performance (twice as fast?)
and when I start the computer it says scanning drives which takes 10 seconds, is this because of my normal HDD's? anything I can do about it? SSD appears fast but comp boots in 70-80seconds?
