MS Navision & RAID

Hi All,

Would like to get suggestions on using Microsoft Navision on SQL Server and the hardware it can work best on.

Have read several articles that mention RAID-10 being a good choice for Navision & SQL, it improves the read/write speeds.

When database sizes grow (like I have a db upto 44gb, running on an IBM x235/2gb ram, etc); what RAID would you suggest?

Thanks,
Ash.
