RAID 0 vs SSD

[highcountryrider]

I'm thinking about putting together a new i5 2500K system. I would love to use a SSD (SAMSUNG 470 Series MZ-5PA128/US 2.5" 128GB SATA II Internal Solid State Drive) for a boot/program drive and use a regular HDD (Western Digital Caviar Black WD5002AALX 500GB 7200 RPM 32MB Cache SATA 6.0Gb/s) for data storage. Even on sale this combination would be about $270-$300.

Would like to know if using two of the WD drives listed above in a RAID0 setup ($120) and another HDD drive ($60-$80) for data storage would be worth the savings and how much a trade-off in performance there would be. Also, opinions on reliability considerations for both options appreciated.

System not to be used for gaming. Light video editing, Photoshop and internet use. I just want a fast system!

Other components being considered for build:
Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case
GIGABYTE GA-Z68X-UD3H-B3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

here is the WD hard drive you will need to use if you building a RAID

the once you chose are not reliable working in a RAID configuration since they do not support TLER

Thanks for the reply. That drive is about $20 more than the one I had posted so that would bring the cost for a RAID set to about $160. They do appear to be more reliable than the one I had selected. If I add a large (1 TB) HDD for storage I'm looking at about $240 + for that setup. The setup with the SDD would be about $30-$50 more. I would expect that the performance factor would be worth the extra $. Does that sound correct?
