[EX Q]: Used card to replace the hard drive in my iPod. Worked perfect and the price was great.
[EX A]: Great item for the job.

[EX Q]: A very nice USB 3.0 enclosed drive that is quiet and actually works. Much better than the USB 3.0 "toasters" that I had continuous connectivity issues with. A+!
[EX A]: Great drive, high quality

[EX Q]: This is a perfect fit for the common 20W/30W/50W high-power square LED panels you see here and on other sites. Mine came with screws and thermal paste for attaching the LED. It's a little bulky but not way out of proportion to the LED.<br /><br />Unfortunately, it doesn't seem to provide enough heat dissipation for a 50W LED. It might be more suitable for a 20W or 30W. With the 50W, after a few minutes of continuous operation at full power, I'm seeing the temperature at the top surface of the heat sink (nearest the LED) at about 120C, and the temperature on the LED emitter surface at 140-150C. That's too hot - the LED really needs to stay below about 50C. I think I'm going to have to look into active cooling with a fan.
[EX A]:
Good fit, but doesn't seem to be enough cooling for a 50W LED
