Just a quick test to see how USB 2 and USB 3 memory stick compared in various ports.

Comparing USB 3 to USB 2, across a few different sticks:\u00a0

The sticks:
OCZ rally 2 (USB 2)

Adata S102 (USB 3)

Adata UE700 (USB 3)

Sandisk Extreme (USB 3)\u00a0

The test:
\u00a0not particularly sophisticated, but the results bear out my general impression. Copy and read back a\u00a01.52 GB video file.<\/p>\n
USB 2 ——
For comparison, a mid-range USB 2.0 stick:
OCZ rally 2\u00a0\u00a0(no practical difference between hubs)<\/p>\n
in USB 3 hub
W: 2:09 \u00a0(that’s 2 minutes and 9 seconds)
R: 0:55 (that’s 55 seconds)
In USB 2 hub:
W:\u00a02:11
R: 0:52\u00a0<\/p>\n
USB 3 sticks in USB 3 & 2 ports——<\/p>\n
Adata S102
in USB 3 hub
W: 1:10
R: 0:22<\/p>\n
In USB 2 hub:
W: 1:10
R: 0:36

Adata UE700
in USB 3 hub
W: 0:35
R: 0:07<\/p>\n
In USB 2 hub:
W: 0:36
R: 0:37

Sandisk Extreme
in USB 3 hub
W: 0:17
R: 0:05<\/p>\n
In USB 2 hub:
W: 0:37
R: 0:36<\/p>\n
Looking at this, several things pop out:<\/p>\n
USB 3 is faster
USB 3 sticks are faster in both USB 3 and USB 2 ports
USB sticks do have different speeds, by a lot
If you have a USB 2 port, there is a point at which getting a faster USB 3 serves no purpose.
Write speeds are surprisingly similar within the same port type… unless you get a really fast stick and are\u00a0using USB 3.<\/p>\n
Of course I’m generalizing here from a -tiny- sample of a simple test. No doubt these things vary with random\u00a0access and so on.<\/p>\n
What does seem to stand out is that USB 3 sticks perform significantly better in USB 2 ports than sticks\u00a0marketed as “USB 2”.<\/p>\n
