Basically I'm installing a Samsung 840 EVO 128gb SSD today, but my motherboard doesn't support SATA 3, only SATA 2. I also have a PCI-E USB 3.0 card installed as the board doesn't support that either (Curse you ASUS! :p ).

Now by reading the specs, I can see that Sata 2 is 3.0Gb/s (Yeah I know, gigabits, not gigabytes :p ) and USB 3.0 is 5Gb/s, meaning USB 3.0 is faster, but would I run into any issues trying to boot my OS from an SSD connected via USB 3.0? (I have a SATA to USB 3.0 adapter, I'd have to run it from behind my Motherboard tray to the back of the outside of the case, but shouldn't be too hard)

Thanks guys :)

bad idea. older mobo doesnt support usb 3.0 natively. so they will only work after OS load its usb 3.0 specific driver

fyi, sata 2 is still super good at around 300 MBps
sata 3 is 550 MBps

Are you sure? I've booted from USB 3 before with a USB installation drive

it ran at usb 2.0 speed before loading driver
which mobo do you have? only recent mobo have native usb 3.0
