I'd say there's not enough data about this particular model to make a confident purchase. Anandtech reviewed a new Sandisk model [anandtech.com]
with a Marvell controller and this one seems to be a lower speed version of the same (look at the size of the PCB inside the case, then read the Newegg reviews of this particular model).
dude, did you see how tiny
that thing is?? would it be bad if you use it like that?
