[nmglug] raid 10 vs 5

[Ken Long]

When my previous employer upgraded their ERP to the latest version, 
the vendor told us they would not support their software on raid 5, 
only raid 10. Their reason was performance. They offered their 
system on both Progress and SQL and both required raid 10.

That was for a lot of simultaneous transactions. For a standard file 
server, I would suspect raid 5 would be adequate.
