I've never set-up a raid configuration of hard drives before, although I did study the advantages and overheads etc of the different raid configurations in computer science, but in the examples we did, the hard discs were the same size. Was this just for ease of explinaiton or is this a requirement of a raided hard drive configuration?
Also, in terms of card readers, whats the advantages/disadvantages of the smargo/omnikey? as in which should i buy and why.
