(hardware) RAID0 SSD configuration

hi all,
I was wondering if anyone had come across a hardware RAID0 setup for at least 4 Samsung 840 EVO SSD's.  I have a Precision Tower 7910, with a LSI MegaRAID SAS 9361-8i 12GB/s  and having problems w/ this configuration.  

Are there other viable alternatives, perhaps using the built in Intel RAID controller? (the workstation was shipped from the factory with no Intel RAID BIOS configuration, not sure if something can be changed at this point).

thanks much for any insight,

Cos
