that sounds awesome!
you mean i can plug a sata drive to my computer while its on and itll just detect it as if im connecting a usb storage device?
isnt it a big risky though? unplugging/plugging a delicate mechanical like a hardrive while its working ?
This is best done with caddies rather than reaching in there and yanking cables. But yes, it is just the same as USB & firewire.
Note: the correct SATA power cable has a longer earth to prevent sparking when being hot pluged/swaped, in other words it is designed for it.
SATA devices are usually optimise for performance, it you want to hot plug I suggest you set it for fast removal. I dont believe any intel chipset support this feature.
