It's equivalent. Archive Manager is essentially a front-end to a bunch of file compressors. bzip2 will give you plenty good enough compression. > I'm thinking more security than > compression though the better the compression the happier I am You can add passwords, if that's your thing.

Note that sharing a single PATA bus is a mistake, though - the bandwidth has to be shared between both drives. > So what I want is to compress the data (saving copying time) and > encrypt is at the same time. That is only going to work if you compress on the NAS; using an external machine means you have to run all the uncompressed data off the NAS, then run the compressed data back on.

I've used luks for that sort of thing before - I once mounted an encrypted file on a machine in Chicago onto my laptop on the Isle of Wight ferry, with encrypted communications all the way. But I was very bored that day...
