what is the Dell recommended RAID settings for SSD such as (read ahead/no read ahead) (write back/write through) (virtual drive cache enabled/disabled)
currently we are running new R730s with LITEON SSDs in RAID-1 with No Read Ahead, Write Back and no caching on the virtual drive. This was the best settings we could find in trolling google and using an SSD benchmark utility.

Hello Arjan
Yes, you can use SSDs in a RAID 1.
The controller supports TRIM and unmap commands. MLC SSDs are consumer grade SSDs that will not have the life expectancy of SLC.
