For now, he does what I ask him back up my data and that's it! By cons I will not use this disk as a single storage medium for the following reasons: - An external hard drive is made to be lugged, may take shocks = reduced life! - Without going into the controversy marks, inside there is a Seagate drive. To recall this brand bought the hard drive division of Samsung in 2011. Now Seagate is not necessarily synonymous with reliability, this may be why they are selling it under the Samsung brand ...
Regarding the cable, it is a bit short it's true but I live with that very well. For others, it will put their hands in the pocket and bought a USB cable type A to 3 micro-USB3 b. The cable is standard.
For reliability, I'll see in time and will not fail to inform you of any problems. Next, we must not go overboard, Seagate is not as bad products!
