    With apologies if this is a dumb question, but once a HD (a LaCie TB drive with two 500GB HDs) is set up as a mirrored RAID using Disk Utility, can I use it with two different Macs (both will be running Yosemite) or only on the Mac that I've used to create the RAID? On top of TM and BackBlaze, I want to use it to back up critical files from time to time on both machines and store it separately from where the computers are located. 500GB is enough storage (mainly want to preserve photos and some docs; everything else is replaceable) for both computers, and I thought that a mirrored RAID would be most secure.

    I thought about encrypting the HD, but not sure how to do that if I'm using it on two different computers, unless there's a program outside of OS X that can do that. If anyone has a recommendation, I'd appreciate that, too.

    Thanks in advance.

    You can use the RAID set on any mac running any version of OS 10 (pretty sure, but certainly any OS since mtn lion). In fact you can set up a mix of drives on different interfaces... as long as all drives of the set are available, the OS will take care of mounting the RAID volume for you.

    Encryption is the same story if you use disk utility, at least since mountain lion, as that is based on the passphrase you set.

    If there are different user accounts (log ins) on the different machines, you will need to think about if you want all users access to all files, or set it up similar to a machine with several users, each with their own space.

    Thanks very much! I'll do a little experimentation to figure out the best solution for me.
