New computers have now been coming with USB 3.0 ports for years. But just how much faster is USB 3.0? Will you see a big speed improvement if you upgrade your old USB 2.0 flash drives?
I have one of the 16GB Sandisk Extreme's and can confirm the rated speeds to be true. Look at Amazon for some of the cheapest pricing on these drives. One thing to remember is even if you don't have usb 3.0 ports this thing will max out a usb 2.0 connection and will STILL be much faster than a usb 2.0 thumbdrive even in a usb 2.0 port. I notice the speed most when installing Windows from my thumbdrive. It seems to take no time at all.
Important to also note the possible issues of driver compatibility of USB 3 ports. I have had two enterprise HP computers (a desktop and laptop) that both had USB 3 but in both cases the HP provided driver caused stability issues in Windows.
My HP laptop running Ubuntu would completely freeze when I tried to transfer documents to a USB 3 device.
I'm sure it'll get better but most of my experiences have been terrible so far.
HP drivers in general have been problematic for me
How to upgrade flash drive USB 2 to USB 3 , possible ? How ?
Buy a new one. You can't upgrade a flash drive directly.
Just a note on some speeds for comparison. I get around 25mb/sec transfer out of my Patriot usb 2.0 thumbrive. I get about 45mb/sec out of my Sandisk Extreme in a usb 2.0 port. I get around 150 mb/sec out of the same Sandisk in a usb 3.0 port.
