Is there a big difference?

post #1 of 5

Is there a big difference between usb2.0 and usb3.0

Also is there a big difference between SATA3gb/s and Sara 6gb/s ? For SSD's not only HDD's

Theoretically, USB 3 is 10x faster than USB 2, however, In my case, it's more like 4. I have a USB 3 external hard drive that can transfer at 80MB/s whereas my other hard drives usually go around 20MB/s. I'm sure there will be devices that can take advantages of the full USB 3 speed.

HDDs don't even fully utilize SATA 3Gb/s, so the new SATA is rather useless. However, there are new SSDs that can utilize the new SATA.

I have my SSD plugged into a SATA6 port but have never tried it on a 3 to check for any speed differences, if any.

USB3 does transfer faster.

Nice future features to have but nothing major at this time.
