Sign of the times: I go into Walgreen’s the other day to pick up a bag of cashews (they’re quite tasty), and in the photo center I spot 4GB USB sticks for $16. Yes, I know you can pick up these things for cheaper elsewhere, but the fact a business primarily known as a pharmacy carries these things is what got my attention.

The brand Walgreen’s carried was obviously generic and not something you’d recognize. This got me wondering whether there is a true difference quality and reliability-wise concerning the flash memory inside a USB stick from one brand to the next.

Curious, I searched the internet to see if anyone has done any testing of flash memory reliability on a brand level.

One such place is CNET and they have a whole section on it. It includes just about every type of flash memory you can imagine with editors reviews, video and so on. The brand you have right now might be listed there, so you can see how it fared out.

The 2 top-rated brands for USB sticks are Sandisk and Lexar.

For everything else, the two top complaints are usually the same concerning USB sticks, that being "slow write speed" and design complaints (i.e. the plastic cap falls off easily, flimsy covering, etc.)

It would appear that yes, there are notable differences from one brand to the next. While a design flaw may be something most people could live with, slow write speeds would drive anyone bonkers (especially considering USB 2.0 transfer speeds are already slow to begin with).

The advice of the moment I give is this:

If you see some generic brand of USB stick, it’s a crapshoot whether or not the design will be solid or flimsy, and whether or not the data transfer will be speedy or not. It might be a few extra bucks for a Sandisk cruzer, but at least you’ll know what you buy will work optimally as it should.

(And by the way, yes the previous link will show you some 16GB versions of Sandisk cruzers. Pretty neat you can put 16GB in your pocket, eh?)
