Re: Raid-5+spare or Raid-10?

I was originally going to only have 3 drives in a raid-5 but then I considered the card would take 4 and could hot-spare the 4th and it wasn't *that* much more to get a 4th drive.  Might as well build this baby properly!

But then with 4 drives I could raid-10 so I was wondering...

The system probably won't be too heavy on either so I doubt I would see
a difference either way I guess.

Yeah I am probably more concerned with reliablity so a raid-5 + hotspare
would be more resilient than a raid-10.

But your first case when you had two failures close together and the
raid-5 + hotspare saved you is the sort of case I am looking for.

Thanks :)
