    I want to back up my home folder files in my MBP to a external hard drive. However, I will be carrying the laptop outside the house and leaving the external drive at home.

    So can I still set up a RAID array>

    If not, what other alternatives do I have that is automatic?

    Thanks for any suggestions:)

    If you want RAID in an external drive, you'll need a dual-disk drive (or a bare enclosure with a hardware RAID chipset) that supports it. WD, LaCie, G-Tech, CalDigit, etc. all make models that will do RAID 0 or 1 (or both) internally in hardware. With one of these, you can unmount the drive when you leave the house and its RAID would still be intact for the next time you mount it.

    You can't of course, set up a software RAID internally on the MBP. It only has one internal hard drive. ;)

    Well I just recently bought a Seagate Freeagent Go 320gb. So does that mean I can set that up an array with it (the external drive) and my MBP's internal drive? Thanks

    No you can not.
    To hav eyour internal drive and external drive as one RAID set, you have to erase both drive.

    Let us know the reason for settin up a RAID.
    Speed? Protections? Application requirement?
