I have 8.9 cm (3.5 inch) HDD gained 2 units Fantec sleeve for my external BackUp plates in a docking station. In principle, make the case that for which they were designed: to protect the HDD against minor impacts and partly also from dust. The execution would in my opinion may be a little more stable. Silicone is suitable for such applications quite well, by the thin wall thickness feels all but very flabby to the "tightening" of hard drives proves to be for this reason as time consuming as one might think. The handling in the docking station can be easily and simply. Therefore, a total of 4 star, 1 trigger there that was saved in the wall thickness and for fumbling when pulled over. Buy recommendation if you know and accept the above points before buying.
