i was told the only drawback is if one hard drvie fails so does the other one. therefore if your really worried about not loosing data raid isnt really what you want. sayin that harddrives dont often fail so its not to much of a concern.

i might get raid, but it will be in a while, at moment i got two harddrives but they are different eg no raid. i have one faster one which has got windows and those types of thing on it. and a larger one that just for storage. eg music work videos. the system works well for me.

You're describing RAID 0, which is used (as you mentioned) for enhanced performance, and you're correct, if one drive fails, the whole array goes down. Raid 1 however, provides data redundancy so that if one drive fails, you still have 1 (or many) backups of your data.
