It's amazing how cheap memory has gotten. They have excellent read/write speeds and as far as I can tell they are built to standard and have good durability. The price is cheap enough to consider them expendable or to lend them (even to less reliable friends). Color coded but you can attach a small sticky label for identification if you wish. Highly recommended. I just bought a small bag.
