I would tell him to go for the random, which is what most DBs would be by
nature. What you need to understand will be the cache parameters, read/write
cache amount, and stripe size, depending on your controller type and whatever
it defaults to on these things.

Subject: [PERFORM] seqential vs random io
I just got a question from one our QA guys who is configuring a RAID 10
disk that is destined to hold a postgresql database. The disk configuration
procedure is asking him if he wants to optimize for sequential or random
access. My first thought is that random is what we would want, but then I
started wondering if it's not that simple, and my knowledge of stuff at the
hardware level is, well, limited.....
If it were your QA guy, what would you tell him?
