I was thinking a big raid 10, (8x500= 2tb) but no hot spare is a showstopper , 
as  they do not have any real IT in house, , it does stink that I will lose / 
sacrifice 2 bays for one hot spare.

Decided on RAID 10 (6x500gb ) for a total of 1.5TB and the hot spare

Yeah, I've run into that as well (no hot spare) and I want to smack whoever did 
the design/config.

As for your question, "aside from a losing some space wouldn't a  raid 6 and 
hot spare make MUCH more sense?"

Well, the answer is, "it depends"  (probably, but I like throwing that out 


This site has been around for YEARS, and provides a good overview of the 
differences (pros/cons/uses) for different RAID configurations:



I used it about 7 or 8 years ago to help me decide whether to go with RAID 10 
or 0+1 on an Oracle DB configuration. (and no, I don't remember which option I 
chose, or why).

"but still raid 5? and no hot spare?"  I've seen this more than once, There are 
a lot of people out there that were taught old school and that RAID 5 is the 
de-facto standard RAID setup so they stick with it for years and years!

So I inherited this server , (sitting on site since February) low and behold 
when I fire it up it turns out that whoever set it up used all 8 discs in a 
raid 5 (granted they are only 500gb enterprise ssd's ) but still raid 5? and no 
hot spare?

I'm trying to figure what the purpose of this server is/was, but aside from a 
losing some space wouldn't a  raid 6 and hot spare make MUCH more sense?

I'd like to move some of their VMs to it, as it is a brand spanking new r730 
with 96gb of ram
