Optimally, Yes, you should replace with exact same brand/model etc... but you CAN replace with a different brand/ model drive of the same amount of disk space or more. It isn't recomended (because of different seek times, cache .. etc..) but if you are carefull and do your research, you can get away with it w/o any adverse effects.

Related to that is length of time drive will remain available. A dirty secret of RAID is that when a drive goes it must be replaced you must replace it with the same drive (please..please tell me I'm wrong). So, unless you have a spare in the back you will end up replacing 3 drives (assuming Raid 5). That may be why the WD model has such low capacity compared with the normal IDE drives. Just my 2 cents worth. William R.
