[ale] SSD for CardBus

[Greg Freemyer]

I don't have an answer for you, but I've been researching SSDs a lot
in the last few weeks.

AIUI:

Most are SATA devices meant to replace your laptop's main drive.  ie.
Same form-factor as a laptop drive.

There are 2 basic implementations at the hardware level.

A) Implement a i/o queue in the SSD and process multiple i/o requests
simultaneously on various parts of the SSD.  This is similar in
concept to how raid works.

B) Process all the i/o sequentially.

For random writes, A) outperforms B) drastically.  In fact B) seems to
perform random write activity as slow or slower than a rotational
disk!!

A) is the future, but only Intel is selling it today.

SanDisk has announced some SSDs that seem to implement A).  The
spec'ed them near the intel's, but at 1/3 the cost.  About $2/GB for
the 120GB iirc.
