Unfortunately at present are 2TB HDD's, 2.5 ", available only with a height of 15mm. Even if this height should be straight so just yet fit flush into the notebook, the resulting heat generated during operation would be somewhere dissipated and will not fry the HD in the heat accumulation ,
The current best price / performance ratio seems the HD-reviewed to offer.
With Acronis True Image 2014 premium clone the process at the external SATA III on USB 3.0 port was not a problem. Further adjustments were made with Acronis Disc Director 11.
The hardware-based disk replacement posed no problem.
The HD is silent in standby and operating and sufficiently fast for a 5.400er plate.
Total will only have to show the time, how reliable is this HD.
