Hi,
Just some friendly advice.
You really shouldn't RAID SSDs. This will more than halve the amount of bytes that can be written to the SSD in its lifetime as you're wearing out the flash memory. You're also maxing bandwidth on internal IO instead of using them on read/write IOPS. I'll give your SSDs max 3 years until they die abruptly. 3 months until you start losing performance.
The only supported RAID format for SSDs is RAID 0. Any other RAID format will severely impair the internal maintenance protocols built into the SSD BIOS. The protocols or plans rather, include Garbage Collection and TRIM command compatibility. Garbage Collection takes care of data that can be deleted (data can not be overwritten on SSDs, unlike on spindle disks. Instead they need to be moved to an empty block on the SSD). TRIM is an OS side command that forces the data to be nulled and by doing so, allows IO operations to continue without having to wait for Garbage Collection to complete. This spares your internal SSD IO capacity. RAID controllers nowadays still do not support TRIM commands passed on by the OS (unless RAID 0 is in use) Furthermore, for successful Garbage Collection and TRIM commands to be passed on to the SSD you'll need at least 10% of unpartitioned space on the SSD. Using 100% of SSD capacity is the worst you can do, whether using it as a single drive or not.
If you're going to use SSDs on an SQL server then use it for transaction logs which writes and reads data sequentially. This is where SSDs shine, in sequential data access, NOT random data access. Random data access performance is actually the benefits of raiding multiple disks.
Only use 1 SSD for logs or 2, but only if they are in RAID 0.
Use traditional spindle disks for Data. Hybrid disks are better, though.
