Hi Jayney, greetings from France ! An intereting fact about RDX I believe : please check on the video I just found there : https://www.youtube.com/watch?v=65bpj1p26fU and please do not miss the instructive comments among which one understands that RDX is nothing else than a common 2.5'' harddrive (brand is seagate) into a plastic box with a bit of rubber suspension. Do not be cheated ! I believe a bunch of external drives (USB or E-SATA) will do the same job and save your money. Having responsibilies in acquiring and preserving audio data, I usually make use of CF cards, making saves on 3.5'' harddrives exclusively, should they be raid arrays or non-raid, but always with redundant copies stored in different places. If LTO seems to be the best placed for long term preservation of huge archives, I believe it is not convenient for a budget or a single entrepreneur and that redundant hard drives may remain the most reasonable option.
