Having had my one and only experience with an SSD that lasted just under 1
year, I'm not very fond of them now. Or at least consumer-grade MLC SSDs.
On the plus side, I've closed a gap the SSD failure happily found in my home
server backups and I have a never-opened replacement Kingston SSD from the
warranty. Maybe I'll donate it to a museum in 10 years.
Thought someone should add a little "Paranoid DBA" rain on the SSD parade...
;)
With the number of drives you're talking about, it sounds like a desktop
tower instead of a laptop. My next purchase for the home server will
probably be an Intel SASUC8I RAID card (LSI controller). It's "only" 3Gb/s,
but that should be just fine for a home/lab environment, no? My fast/noisy
10K Raptors should work well and still be cheaper than equivalent SSD
storage.
Power? Noise? Well...not too sure on the power...

Disclaimer: Newegg has the RAID controller for ~$160 and 250GB Raptors for
$110 (500GB $150).
