Increments of 80 GB were fairly common. My desktop had an 80 GB Maxtor and my laptop later had 320 GB.

In hindsight, I do not remember if the Maxtor was definitely 80 GB, or if Windows was showing it as 80-something GB. But the laptop was definitely 320. I googled it. Google AI of course said "Based on Ebay listings it seems to be 1 TB", very useful. Spec sheet says 320 GB.

Man, I remember lusting over getting a WD Raptor back in the day. They were so much more expensive and lower data density it I couldn't justify for my low budget.

As was already said, 160 was pretty common, think increments of 20 or 40 is what i remember. Raptor drives had kinda odd size increments compared to other consumer drives. Looks like it would be 36Gb circa 2003.

I once got some retired scsi drives. Man 10,000rpm drives were loud and hot...

Thanks for bringing back some old memories
