######### Important! The one with the "B" in the name is expandable #########

I have in the heading Extra, the "B" mentioned as the "C" apparently
indicating that the USB connector is soldered to the hard drive.
My plate is the Toshiba HDTB115EK3BA 1.5TB external hard drive (6.3 cm (2.5 inches), SATA, USB 3.0) Black.
Images in the installed condition I set.

There is the Toshiba HDTB115EK3CA Stor.e Basics external hard drive 1.5TB (6.4 cm (2.5 inches), USB 3.0) Black.
I suspect that the difference between the two models of the inserted or soldered USB port.
Stupid, a nameplate at the reviews of "C" plate photographed with "B"
In the peer-reviewed by me "B", the hard disk in every case is expandable, since the USB connector is plugged in.
That struck me as the hard drive from table height struck me the stone floor and thereby laterally opened.
Since they did not run it has this also survived unscathed.

Using the fingernail then I was able to solve the remaining tabs and try if I can remove the plate.
What a blessing in disguise :-)
The opening and resealing went smoothly.
So you would also be used in the notebook.

The built-in hard disk of Toshiba HDTB115EK3BA is the Toshiba MQ01ABC150 with a thickness of 12.5 mm.

The hard drive turns on both the computer as well as on my TV Box VU + Ultimo automatically.
This is extremely convenient.
Just as the fact that it draws so little power to my TV box,
I still can connect a second portable disk plus USB stick simultaneously.
Moreover, it is very quiet and is also on the wooden table no audible vibrations of itself.

The only "downside" was that I found was the unfavorable shaped housing,
which conically tapers toward upward.
This shape was also the reason that they at me raising
has slipped from his fingers and dropped.

The solution is to operate the hard drive on his head
and provided with four rubber feet from the hardware store.
Then, the housing tapers downwards and is in accordance with grip.

In any case, the plate can be removed for the failure of the controller or the socket
continue to be used with a USB adapter, replacement housing or computer.

I am satisfied with the hard disk and advise everyone to "B" to pay in the name.

I can say almost nothing about the speed, since I operate on USB2 (They but is very fast).
