Question : exchange 2010 storage

Im planning  to deploy exchange 2010 for my 3000 users base. I’m going to use SAS 7.2rpm speed drives for storage; thus, taking Microsoft’s word that exch2010 is designed to use these slower speed capacity based drives (thoughts?)
Im thinking of using DAS to an msa60 with 10TB usable storage. Should I cut the 10TB into separate arrays for each database or just create 1 array and make multiple virtual drives for each database?  I want to get the best performance so recommendations are appreciated!

Answer : exchange 2010 storage

Do you have any site from which you can import the currency rate. If yes, then you can use-->data-->external sources and from web and then you can process it from there.
