Hey guys, im wonering if it is possible to make 1 partision of my iMac 1TB hd and a external Hard drive. The reason i'm asking is because i'm streaming TVshows from my mac and i would like to all my Shows in 1 folder , so i don't have to look for a show on my mac and my external hard drive, i want everything on my mac HD. I know i'm explaining it kinda weird, but please try to understand.
 
HFS+ does not allow partitions to span drives (physical volumes). ZFS would allow it, but apple dropped development due to licensing issues. At the moment, you're limited to partitions that do not span drives.
 
A RAID of 2 1tb drives only yields 1tb of storage, right?
The OP is talking of 500GB internal + 1TB external into a 1.5TB drive.

I used RAID to make each 1Tb drive equal a larger 2Tb... for speed... sadly not safety...

I know of no way to have 1 and .5 equal 1.5 but I am no judge of all known knowledge... also sadly....;)
 
If you have 2 1TB drives in a striped RAID, then you get 2 TB storage. I was thinking you were doing a mirrored RAID, which would only get you 1TB storage.

So I suppose you could set up a RAID striped, but I doubt you could do it with the system already running; you'd probably need to set up the raid first then re-install everything. Also if you do this, if the USB drive dies, your whole system cannot boot. If the external HD is USB, it would be slower than the internal drive, which would lead to some strange performance issues.
