It wasn’t. IMHO the best feature and only real reason I hang around HN is exactly because I get to interact with others who know more.
The magic is in knowing how the trick works.
A bit further down the comment chain, martinald has a great succinct explanation:
I grew up in the 90s, on 56kb modems and PCs that rumbled and whined when you booted them up. I was at the tail end of using floppies.
I never said I didn't love the speed of SSDs, and when they just started to become mainstream it was an upgrade I did for everyone around me. I made my comment in part because you mentioned dumping 4K into the SSD and/or editing it. It can be a nasty surprise if you're doing something live, and suddenly your throughout plummets, everything starts to stutter and you have no idea why.
