raid (was RE: OT: Dell disks)

[Michael Butash]

Agreed - I have a separate nas I rsync important data regularly with 
between my laptop as I often work away from home, here I just use the 
nas.  Problem is I don't always have my laptop on at home, and sometimes 
goes weeks without replication.

I run the ssd's in raid1 as a) i want *some* disk-level redundancy so as 
not to rebuild my desktop from scratch yearly when they puke and b) want 
the speed, so am willing to deal with their questionable nature.

I'd buy some of Rusty's companies industrial ssd's, but they don't seem 
to sell to want to sell them easily anywhere, and what I do find for 
sale is insanely priced ($10-20/gb).  Nor does anyone commonly sell them 
even if i were made of cash.  Kind of annoying to get enterprise stuff 
at home you have to hit secondary markets ala ebay, sorta like a 
crackhead hitting a swapmeet for off the back of the truck goods. 
Definitely not something I want to get "refurbed" after some enterprise 
has run sql db's off it for 2 years already.

I might pay double to avoid the stress of rebulding the os yearly with 
crap ssd's (which seems 98% are), but not 10-20x.
