I bought a 40GB SSD back when they were $300. It was the main drive in a Mac Pro G5, then a Mac Pro Intel, then a Macbook, and for the past three years a Mac Mini. Drive Genius gets pissed off at it every couple months but other than that it just keeps on truckin'.

I've heard nothing but bad news about fusion drives (seems kind of like the worst of both worlds to me: all the expense of SSD with the unreliability of spinning platters) but I'm sold on SSDs, at least for fast access shit.

Vaguely related note: One of my drives in my NAS started throwing errors about a month ago. By last week it had Xd out 60 bad blocks. So I called up Western Digital, waited two days, and had a new drive. Then I powered the array down, pulled the drive, swapped it out, listened to beeping for 30 seconds while I configured the wizard, and then 27 hours later it had rebuilt a 16TB array with 12TB of data on it.

No data loss. No availability loss. The thing was inaccessible to my machines for a whopping 5 minutes. Four different boxes wrote AFS and chron jobs to it while it rebuilt. I'n'I am fuckin' sold on Synology and fuckin' sold on Western Digital. The fact that I was able to see the drive going south before it actually did anything, combined with the fact that I could yank it like a bad tooth and put it back together again without ever once encountering any drama is exactly what I wanted out of a backup solution.
