Is there any reference sites or configuration to run SQL DB in PCI-E flash cards only?

Hi experts,

  I run our SAP/SQL in HP EVA 8400 now but the MA will be expired soon. I plan to migrate to an ex: P7400 mid-range storage.

  However, a consultant give me a very interesting idea. Our database is about 6.1TB now and we expect it may grow to about 10TB in three years. If we bought sixioDrive2 Duo 2.4 TB PCI Express 2.0 x8 MLC Solid State Drives and create a RAID 5 disk group, we will get a 12TB disk volume stored in SSD. According to this link(

   So the question is: is there any reference site or configuration to prove that this idea is applicable?
