Do you know how is this model is called?

Hi! A long time ago a friend of mine bought a Sandisk pendrive which is faster than anything I’ve ever seen before, but he refuses to sell it to me (with good reason) and he even refuses to tell me the model name or anything that helps me to get one. So if any of you knows the model or anything, please help me.

The stick itself is black, with a lightblue-painted metal swivel. I don’t know the exact measures but it’s really tiny, no more than 1 inch long and half inch wide. I didn’t benchamarked it, but I tryed it a few times and windows tells me that it copies at 40MB/s. And that’s it. If I can get a picture of it I’ll post it right away.

THanks in advance!
