Hi All,
Ok.. I have a nice collection of external HDD and I think i can improve my general iMac performance by using RAID... but in what configuration?
I have about 1.5 gig of data, some of which could be "quick access" and some library only so slow access is fine.
I have:
250g Lacie firewire
1TB Lacie firewire
2TB Lacie firewire
2TB USB
4TB USB3 (although I have no USB3 ports... just the way the drive came!)
I'm planning on using....
250g as an off-line clone of my iPhoto Library
Via my Airport Extreme and stashed in safe places round the house:
2TB USB as - clone of iPhoto Library+ clone of home movies + 500mg partition as iMac HDD clone.
4TB USB as a time machine.
So that's me backed up.
Then for iMovie, Photoshop, Logic etc I want to use:
1TB Firewire + a 1TB partition of the 2TB Firewire as a RAID for speed.
The other 1TB as slow library storage.
but what RAID do I use?
I want to use stripped for speed but worry about reliability? I'f I'm fully backed up.. am I worrying about nothing? Also, stripping apparently has to be identical disks? Although I went though the first bits of creating the set (without pressing "GO") and it seemed to accept the Disk + Partition as a set?
Or, to be safe, is mirrored better?
Also... will the resulting Stripped RAID be quicker to access than my internal SATA?
Interested in your thoughts/experiences....

Ok... Update.
I have freed up my 1TB and created a RAID0 set with that and 1TB of my 2TB drive.
It works flawlessly and offers absolutely no speed increase whatsoever!
The "slow" half of my 2TB gets 60-70m/s from Drive Speed Test and the RAID drive gets exactly the same?!?!?
What's that all about? - Is it just because my Mac is ancient? My internal only gets 70-80 as well...

P.S. - Am I talking to myself here
