[nycbug-talk] Raid 5 or 10 with 8 drives?

[Francisco Reyes]

I have a machine with 8 drives and considering the two following 
configurations:

6 drives in RAID 10
2 Hot spares

or

5 drives RAID 5
2 drives RAID 1
1 Hot spare

The machine will be used for NFS storage for IMAP/POP (mail machines). 
Likely will also get a simmilar machine for database in the near future. 

Which of the two above should perform better?
The one with the RAID 5 has the appeal of more space but only if the speed 
will be comparable.
