For example: [URL] Drives should be Dell-certified, but you DON'T have to buy them from Dell. Many resellers carry Dell-certified drives - their selection is often better and their prices almost always are better than buying direct from Dell. As long as the drives are certified, then it doesn't matter which make/model you get ... the drives CAN be larger than the original. They CAN be slower (10K/15K), but that is NOT advisable, as your array will perform according to the specs of the slowest/smallest drive in the array.
