The bag I have for my "Toshiba STOR.E SLIM HDTD210ES3DA external hard drive 1TB (6.4 cm (2.5 inches), USB 3.0) silver" bought. The hard drive is an excellent fit in the pocket. Between disk and pocket edge is still about 0.5 cm square. The 2nd partition can be used very well for the connecting cable and / or other accessories.
The processing of the bag is good. The bag is my feeling - contrary to other reviews - sufficiently robust to protect the hard disk. A (chemical) smell the bag I could not tell.
All the best and therefore maximum rating.
