I recently got a mac mini and upgraded the ram to 512. the one thing I still want to do is upgrade the internal hd to a faster drive but I would also like to gain some space. the original drive is only 40GB and 4200rpm. I would like some opinions on whether to buy a samsung 80GB 5400 with 8mb buffer or an ibm/hitachi 40GB 7200rpm with 8mb buffer. I have narrowed it down to these 2 as they both come closest to my needs and are also in my budget. I have to admit that the extra space would be nice on the 5400 but the speed of the 7200 would be nice also. with the 7200 I gain no space though ideas?
