I need to build a new server for our ERP database system I good with all of the parts I want but I'm pondering the storage. The current server uses less than 20GB on the OS drive and less than 40GB on the database drive. Both are RAID1 pairs. DB only has about 10-12 concurrent users/processes running at any given time. I was pondering going to SSDs for the OS drive and 7200s for the database, but I'm wondering if I might see better performace if I leave the OS on 7200s and put the database on SSDs. The database probably has a 60/40 read/write ratio when you look at usage. Looking at using a 6-core Xeon with 24GB of RAM. Thoughts?
