USB 3.0 Speed question

post #1 of 4
Thread Starter 
First time using USB 3.0 here. (i am kinda late on this lol)

I have two USB 3.0 drives. Both of them transfer files TO my computer at a rate of 120MB/ second. Does this about sounds right?

Also if I plug both USB 3.0 drive into the computer (both are USB 3.0 enabled ports) and copy paste files direct from one External Drive to the other External drive, I only get a speed of about 20MB/second.

What is the cause of this? thanks for the help! biggrin.gif

thanks for the reply.

When you transfer from external to external it drops from 120MB to 20MB....that's normal?

It all depends on speed of the drives, how fast/good the USB3 chipset is, and how big the files are (smaller files = slower speed)

Also generally READ speeds will be faster than writing, so external to external may be sightly slower?
