So I bought a samsung 840, I'll be using it on a single-disk system, 
requiring encryption (luks), and lvm/btrfs.  Might actually try btrfs 
finally now, but this is for work.  Just curious your opinion about the 
firmware side to expect these days losing trim support with fs layers, 
but relying on built-in firmware auto-leveling.

Most of what Lisa suggested to do I normally do already, I just still do 
manual alignment of cylindars of the disk for flash geometry (or plan 
to).  Is that even needed still for non-gpt installs (like ubuntu)?

Longevity seems almost a crapshoot with ssd's at times, so just curious 
to know what enterprise storage systems use on the back end with ssd to 
keep them from dying with layers of raid and such.

I did buy the samsung 840 "pro" disk, just curious what makes it so pro 
vs cheaper 840 (~$50 diff).  Since single disk, I'm hoping it holds up 
longer.

Thanks in advance!
