For Mac last generation - and for them alone.

No need to whine about the lack of connections and compatibility: this drive exclusively target Mac users last generation (post-February 2011 for the MacBook Pro, in May 2011 for iMac, MacBook Air in July 2011) and thus equipped with a Thunderbolt connection. If this is not your case, go your way. And if this is your case, this drive is ideal. Perfectly designed, it is very simple to use, powerful, and its configuration possibilities can satisfy both fans demanding that the professionals concerned to protect and safeguard their data - ideal for a photographer or videographer, for example.
The MyBook 4TB is actually composed of two 2TB hard drives.
Regarding the use: the first use, when the DD up on your desk, it is a .dmg file just unzip and install in your Applications folder in order to have the program that Drivera SD. This program is very simple and offers three possible configurations:
- Stripe (maximum capacity and performance: you have the start of 4TB)
- Mirror (maximum protection of data: the second hard disk works as a mirror and always saves the data of the first Once the My Book capacity is reduced to 2TB, but this solution is that of those who want to protect sensitive data. particularly in the context of a professional use.)
- Individual hard disks (you have two 2TB HDD - the My Book Thunderbolt with two outputs, you can drive the independently - this option is only available to owners of iMac, which have two outputs Thunderbolt , the MacBook does have one).
Finally, the two hard drives are removable and can be recovered easily.
It is recommended that this drive in a stable place, flat and airy - like many hard disk, it gives off a substantial heat when operating.
Regarding the connection Thunderbolt, its capacity is 10 Giga / sec. But beware, do not dream it's a theoretical capacity which is obviously limited by the velocity of the My Book DD (one would like DD faster to the extent of this new technology) or that of your computer and your other hard drives (if you transfer their data to it) - the strength of a chain is that of its weakest link, and your computer certainly can not deliver 10 Giga data in a second, no more than the DD the MyBook can not burn as much information per second. Thus, if DD is perfect for Time Machine, the backup is not done in 10 seconds either! The 250GB I had to back up via TimeMachine for my first use took nearly two hours. Still, the connection Thunderbolt, being twice as fast as USB 3.0 and 10 times faster than FireWire800, offers a speed much higher than any currently existing standards.
Important detail - and negative: the indispensable Thunderbolt cable is not supplied with the HDD. Therefore include the purchase - and this is an expensive connector (almost 50 euros for the one Apple sells).
Finally, little more enjoyable: with its discreet witness and his trim gray aluminum, the design is clean and simple, elegantly designed to marry with that of Apple.
