Do I understand correctly that you can add an expresscard SSD drive and
use it as the boot drive, leaving the original spinning drive in place
to use for storage? This might be the best way to go. I could, for
example, put Fedora or Ubuntu, and ~/ home on the SSD drive, and mount
the spinner in a folder in ~/. The expresscard SSD drive wouldn't have
to be more than 32 GB or so.

Another option is a Seagate Momentus which is a hybrid. Evidently it
contains internal software that uses the SSD portion for files that you
are using a lot, and the spinning portion for everything else,
allocating the usage dynamically. It's an intriguing concept, but with
the Momentus the SSD portion is only 4 GB. 

As a second question, is there data anywhere on real-world read/write
speeds of the various SSD drives currently available. Technical specs
are fine, but I'd also like to see customer reviews.
