The synthetic benchmark scores look great but unless your rig is some kind of working server/workstation with massive I/O's or huge amounts of data being simultaneously read and written its kind of pointless to have RAID SSD's really.
If you just want a desktop machine that boots up fast and is snappy you dont need to Raid0 SSD's. Its not going to make your games any quicker and youre likely not going to feel the nanosecond of extra speed it could possibly bring you when opening up your web browser or email client.
What you will do with Raid 0 is spend more money on two drives, run the extra added risk of complications and failure, added latency and on most motherboards a slower bootup time due to onboard raid initialising.
Its your choice
