Changing PS4 HDD -> Help!

[Conina]

Here are some comparisons between the standard HDD and a Samsung SSD 840 Evo:

boot time: 6 seconds faster
installing a game: 6 - 7 seconds faster
starting a game: 1 - 5 seconds faster
loading a level: 3 - 4 seconds faster

These few seconds faster loading times aren't worth several hundred bucks (IMHO).
I will get a 2TB-HDD, when they are available.
