Go.

Basic file server. I've always done RAID 5 w/ hot spare or RAID 6. What is the advantages/disadvantages of 1+0?

I know, Google motherf*cker. Just looking for personal experiences.

Raid 10 is much faster but you literally lose half of your storage capacity.

If you only have 4 drives, raid5. You're "losing" a lot of storage by going raid10. Critical databases that need faster read speeds for big companies need raid10.

Raid 5 is a sucker bet. Mirror them. Drives are cheap.

Drive failures in a Raid 5 are NOT independent events. Too many people too many times have seen a second failure during a parity rebuild.

Whatever you do, back up anything on the array that you care about. Back it up religiously, and practice restoring once in a while. Raids will fail. They really will.
