"Six 470-μF capacitors connected in parallel are used to store the
required emergency charge and keep the drive alive long enough to
flush out ongoing operations in the event of a power failure."

Wow ... 470 μF in such a small package!

I remember hearing about a computer that had just enough internal
power to write its brains to disk when it lost the grid.  So ...
really, the SSD is a computer (it has a processor) and hands off cache
to NAND flash before the end comes.  Nice.

Do y'all realize we're talking about a $1300 drive in this case?
(100GB is $400 at NewEgg, but the article discusses the 200GB model,
which I cannot find below a grand.)  The vendors are still able to
gouge "enterprise" customers.  [sigh]
