Which HD is right for me: the faster 7200rpm 60gig, the elcheapo standard or even none and then buy the one I want cheaper somewhere else, the 5400rpm 80 or even 100gig that's available in someplaces and is argued to be as fast or faster than the 7200rpm 60gig because of its larger platters and less head travel?
Also, is the speed gained by a Raid0 array worth the extra noise, heat, breakdown potential and increased price? I am also considering the Raid1 array which has the same problems but instead of an increase in speed, you have a decrease. However you do have the advantage of experiencing no down time if one drive crashes. Wouldn't it be better to simply buy an external drive to keep your data backed up on, because with the Raid1 array you just have a duplicate of any mistakes made on the primary drive anyway and an external is cheaper and will probably outlive the notebook?
