Your methods are not sufficient.  Newegg doesn't provide the necessary
information in it's product database.

SandForce 1000/2000 series controllers do automatic transparent AES-128
or AES-256 encryption depending on controller model, and do so while
achieving much higher performance than all other SSD controllers on the
market.  They also support a boot time disk password.


This $45 40GB Mushkin drive has an SF-1200 controller:

This $90 120GB OCZ Agility3 has an SF-2281 controller:

Thus cost isn't really a factor.  The $45 is current regular price on
Mushkin, not after rebate, etc.  Frankly I'd be surprised that anyone
would be anything but a SandForce based SSD today, given the
price/performance/capacity ratio.  The OP's SSD may in fact be a
SandForce model, and he may simply not be aware of it, or the features I
mentioned above.
