Western Digital My Book Thunderbolt Duo dual-drive external storage 4 TB (Personal Computers)

Customer Review

This outer casing My Book Thunderbolt Duo Western Digital is a true backup center at home, due to its large size (not counting the take with your MacBook!) And capacity: 2 hard drives 3 "5 2TB !
Note that it is possible to replace these 2 hard drives at any time without the need for screwdriver (a hatch allows to do very easily).
To store as many files, it is imperative that the transfer takes place quickly. This is the case here, thanks to the Intel technology: Thunderbolt. This port provides data rates in input / output 10Gb / s. The housing has two Thunderbolt ports to connect other devices 5 "Thunderbolt" series. So do not expect to use it with an Apple computer released before February 2011 or a PC, as the case does not have USB or FireWire port (there are still adapters, but expensive). However, Intel announced earlier this year that the Thunderbolt would spread to non-Apple computers.

Operating side, nothing really revolutionary. You just have to connect the adapter to the power of the house (the power supply is provided UK!) And connect the device to the Thunderbolt port on your Mac (tested here with a MacBook Pro 2011 - 13 inches - OS Lion) with a Thunderbolt cable, kindly supplied by Western Digital for the purposes of this test, but usually not provided (count 50 still this official cable).
When first starting, it is proposed to install a small software that helps manage 2 hard drives, to prevent possible failures - either in hardware (eg overheating) or computer - or format hard drives. And it is here that reveals the true value of this case: it is possible either simply using 2 separate hard drives (JBOD - as if they were two 2 terabyte hard drives); either to use one partition for the 2 discs (in this case the computer considers this a 4 terabyte hard drive!) (RAID 0); or whether to use the 2 hard drives to backup your data 2 times (1 each!) for safety (RAID 1).
We must emphasize the value of the first solution that allows the use of a disc recording format of the Mac and on the other drive Windows size (provided of course that Windows is installed on a Mac, Thunderbolt requires).

Recently, Apple offers the Time Machine application. This application provides a copy of all your computer (in one click), updated regularly (several times a day, by default) at the option of deletions / Data creations. The great interest is the possibility to go back at any time (without saving each time the entire computer!).
The housing offers this application at the first startup. If the application already has a hard drive of reference, simply go into TimeMachine and click "select disk".

I personally use TimeMachine with the housing in safety mode (1 copy on each disk). During the first backup, the system has copied 280 giga (x2!) In just over 3 hours (I used the Mac at the same time to do other things).

Hardware side, the housing does not heat at all, even after intensive use, and it makes no noise. A small LED on the front lets you know if it is on, off, or in sleep. It should also be noted that there is no switch over. To turn it off, cut the power supply (after removing it properly on the Mac obviously).

A guide "paper" quick start is provided, and a more detailed digital guide (thirty pages, multi-languages ​​including French).
