I switched from just using a bunch of drives to a RAID 5 array in
November. In December, just after I left for 2 weeks out-of-town over
Christmas, one of the drives in my RAID array crashed. The array itself
stayed up, with no loss of data, until I got back to town two weeks
later and was able to replace the drive. 8 hours later, the new drive
was completely synched and the array was again protected from a drive
failure. I am sold on RAID 5, and consider the loss of use of one drive
in the array to be a worthwhile trade-off.

Thanks for answers. As i said, I don't need space for recordings, only
for media (pictures, avis, mp3:s etc). My recordings are on separate
disk, and I don't care loosing them if disk crashes.
As everybody says, there seems to be no other way than LVM or Raid. I
decided to go with Raid5. This was also my original plan, but after
building an array, I did some testing with bad results;
- I plugged one sata disk off when array was running. It behavied
correctly since I rebooted, simulating disk change. After that I could
not activate array anymore, I couldnot remove "broken" disk and couldnot
add new disk. So I lost array contents.
After that I built new array, with --force, (I noticed, that mdadm
creates one failed device as default) and now I hope I can make test and
recover succesfully. I'll test it again tonight...
