Exchange 2010 - Still need fast HD's?

[stoofa]

We're currently sorting out an Exchange Server for our offices in China.
Currently 11 people out there, might grow to 15.

With Exchange it has always beenr ecommended that you use fast HD's.
Our early Exchange 2000 servers all ran on 15k SCSI disks.

Could we get away with a RAID 5 array of 7.2k SATA HD's for Exchange 2010?
Or would we be better off going the SAS route?

Thanks for that.
We're going to kit it out with a 4C Xeon 2.4GHz CPU.
Then 12GB of RAM.
So it looks like we can go for SATA over SAS for the drive array.

Cheers.
