We are in the process of ordering a new server and the hardware guys are asking about how we need to setup the arrays / drives. We are moving to Server 2012 and installing SQL 2008 R2. If we are using Solid State Drives do you get better performance having multiple arrays each with their own logical drive or is the performance about the same using one RAID10 array and split that into logical drives for the OS, data logs, etc? Everything I have found says to split it on physical drives, but most are referring to platter drives and not solid state. So if anyone can give some insight on the best setup using SSD that would be great.
