Are you talking here about SD cards or about USB flash discs?

Re brands, I already gave you one such brand: Corsair, but there is 
another one - do a search on reviews of flash discs/memory sticks.

This of course applies here in Australia and where you are it will be 
different but you will get the general picture about the prices of 
things. This is from the shop I normally do my buying so have a look 
around re SD cards, USB flash discs and whatever:

Now, I think that you ought to break up your needs into the 2 
categories: CDs with music on them and then the DVDs with movies on 
them. Reason: how many DVDs do you think you can get onto, say, a 32GB 
USB flash? Let's say 8 single layer DVDs which works out at around $16 
for each DVD (using the price list I just supplied above). For that 
money you'd be better off going out and buying another copy of the DVD 
from a DVD rental shop which always sell pre-loved DVDs. Compare this to 
using another blank DVD to burn the original. The cost is even more if 
you talking dual-layer DVDs- half as many as the single layer making 
each DVD cost around $32 each.

With CDs on the other hand it's a different story. The CDs are less than 
700MB each so you can store quite a few bits of music on a memory stick.

But....you did read the article about ReRAM (memristors) which are due 
out in 2013, that's only 2+years away? Use some interim measures to 
backup your CDs/DVDs and then splurge out in 2013! :-)
