Yeah. Buying 128GB USB Drive with USB 2.0 only is like driving with flat tyre. Cold.

Two things, I would say:

(1) As WillPS says, it will afford you a degree of future-proofing.
(2) AFAIK, many USB 2.0 memory sticks do not operate anywhere near the maximum theoretical performance level of USB 2.0. Most USB 3.0 will outperform USB 2.0 sticks, so you will be using a faster memory stick even if you can't necessarily utilise it's full speed.

Basically, using a USB 3.0 memory stick is very unlikely to have any disadvantages and very likely to be beneficial.

Potentially it will be useful in the future. I've bought mine to load with content and stick permanently in the back of a Roku 3 box - it'll be fine for that.

I don't have a USB 3 port on my computer, so what difference will it make buying a usb3 stick?

usb 2 but hot anyway

I have gone off Sandisk products because of:
1. Corruption over time, makes Kingston and Samsung a better choice
2. Slow write, yes 'write' speed, makes generic brands attractive which tend to be reliable too somehow

128gb on USB2. Worth paying the extra £2-4 for USB3 every time at this size.

I'm pretty sure that the my memory sticks are just rebranded lexar sticks. USB 3.0 is the clincher

I did look at that but I'd prefer to pay £1 more and go for a Sandisk product which is guaranteed for 5 years; plus free next day shipping.

...and the USB 3.0 128GB are often around £20

Not a bad deal... But for people who care it is USB2.0

The norm these days is the faster USB3.0

Was looking for one, thanks
