I remember when I bought my first SSD(s). I was quite a holdout for some time, while the early-adopters on this forum were persistent in their praise of SSDs.
TBH, I don't run a lot of junk on startup or in the background, like OEM machines do, so I was pretty happy with a decent HDD.
What really sold me on SSDs, was the objective, quantifiable performance difference with things like MalwareBytes scans. Going from 15min where you really can't do much else with the machine due to heavy disk I/O, to 2-3min where you can still web browse and run other programs without much slowdown, was wonderful progress.
And I wasn't even using a "fast" SSD, my first few were 30GB OCZ Agility. I still didn't trust the technology very much, so I wanted drives that were able to be de-bricked by the end-user.
