Looking for more storage, I came in various forums on the Hitachi. Particularly quiet operation and a fast access time was me with this important and draw the panel according to various test results and user opinions.
Because in my computer from Apple a Hitachi was also installed and these my criteria corresponded to the capacity, I ordered without reservations.
The disk came amazon typically after about 2 days with me and was installed directly. The Macbook recognized without problems and "Mountain Lion" Read to install smoothly. So far so good.
But what struck me in direct comparison to smaller Hitachi, is the louder operating noise of the 750GB version. It is far from being loud pottering as with some other manufacturers, but as sums, similar to a small fan to perceive. In everyday life, almost silently, in a quiet environment or night but already audible.
Probably the noise level is within the normal range and is bleating at a high level, but who is keen to work given by his silence Macbooks, could be somewhat disappointed.
Nevertheless, the Hitachi does a good job, is fast and large memory an absolute blessing.
So if you can overlook a slight increase in volume, in favor of speed and space, is served here well.
