Hi, Raony.<br>
<br>
RAID0 is quite risky because if *any* of your disk fail you will lose<br>
everything!<br>
<br>
I would use RAID10 instead or use two of your disks in RAID1 and backup<br>
onto the third single disk. Disk capacity is important, of course, but<br>
you risk losing everything unless you are backing up your RAID0 onto<br>
external or network disks.<br>
<br>
If you *really* want to live dangerously, you might try out Btrfs!<br>
<br>
I'm running Bio-Linux 8 on an 8-disk Btrfs RAID10 on my personal<br>
Bio-Linux workstation and it performs very well. I've been doing<br>
disaster-recovery testing and it all seems to work very well. The only<br>
real problem is that you can't swap on a Btrfs filesystem, but you can<br>
mount a file on a loop device and swap on that instead.<br>
<br>
I think Btrfs is the future :-)<br>
<br>
Bye,<br>
