I have 2xWestern Digital 800BB drives in RAID 0, they see heavy constant use as they hold my movie server space, I have never had problems, very fast, no data corruption, i have had one for 6 months, the other for 4, love them both. Oh and btw, many (i am not implying all so please don't start flaming) hard drives fail due to poor cooling or devices piled on top of one another, I see it all the time here at school, someone's drive dies, I take one look in their box and touch the case and almost burn my hand. Hard drives need to be babied, as much as your processor as they're pretty damned important, I run 4x80mm fans over mine and they stay chilli to say the least and I never have problems. I reccomend looking into hard drive cooling options, it does help, especially if you're in an unaircondiditoned place.
