I know that this may be a stupid question to some but I don't often work with SCSI drives with what seems to be non-standardized sizes compared to SATA drives. I currently have a RAID1 of two drives on an old Dell server and one of the drives has failed.
The current drives are Maxtor 73GB SCSI Ultra320 80-pin 10k (8J073J002075E). When searching for replacement drives of similar specs, it seems that 72.8GB drives are most commonly listed and 73GB drives are more rare.
Is this a case of a manufacturer rounding up on the capacity or is there a real 200MB difference going to cause an issue?
(Note: I realize that the general rule of thumb is to replace with all the same specifications or higher -- this question is whether the difference between 72.8 versus 73 is just labeling versus actual technical difference in size.)
