I had decided on the Toshiba 500gb portable hard drive (the red one), but wasn't sure which case to get with it, as there were a few review complaints about the size of the "what do people also buy with this product" recommendation. I won't say which one, but people had said it was much too large for purpose. So after checking out measurements of different cases I settled on the Iomax. It's a neat little case, fits the above device spot on and I think with the two opposing hard shells, will give ample protection. Hope this saves you a bit of time looking.
Don't often move my external hard drive but when I do it's often to other parts of the country and sometimes the world. then I know I need to have the hard drive firmly secured and protected. This does the job admirably. Well priced, great delivery, I would recommend.
I wasn't quite sure that the case would be good enough to protect the hard-drive, but when I got it and saw that it have a protective layer inside, which buffers the hard-drive against any possible accidents, I was pleasantly surprised.
