Alright, based on performance, what's better:

6gb SAS drive with 15,000 rpm and 16MB of cache

--------------or-------------

6gb SAS drive with 7,200 rpm and 64MB of cache

I'm betting each one has its pros and cons, but I don't know much about server hard drives.

Thanks in advance,

Solution
the 15000rpm card will outperform the first card in all scenarios (all things being equal) apart from scattered but consistent small reads/writes.
