What many people (not quite accurately) call raid 10 ... Also not
accurately
called stripe of mirrors ... More accurately, a concatenation of
mirrors.
Get the capacity of 5 disks when you bought 11 (assuming you
dedicate a
hotspare).
wouldn't a concatenation of mirrors imply that you write sequentially
to a mirror until full before using the next mirror? where's the
benefit in that? io to my raid10 is striped thank you very much.
as to why people would use other raid levels: sometimes you need
performance, sometimes space, sometimes redundancy. I'm grateful for
the plethora of raid levels at my disposal jefe.
