People keep saying this about RAID. (it kicks butt! its honking fast!
etc).
Fine, we all know RAID is fast. BUT, has anyone done an apples to apples
comparison of a squid w/RAID to a squid without RAID?
I'm talking about a cache with 5 standalone drives vs a a cache with 5
drives in a RAID array. No fair comparing a RAID setup to a cache with 1
drive.
I haven't either, but I'm guessing you would find that, in this particular
case, RAID is not all that much faster. Squid divides up your cache
between the 5 drives, and statistically there should be enough randomness
in the requests that IO is divided fairly evenly among the drives.
Note I am NOT talking about RAID in general. I am talking about this
specific application (squid cache).
