This hard drive can be easily connected to a USB port and install runs quietly (because very quietly) alongside. So far I have two of them put into operation and both work wonderfully. The only drawback is the fact that they can not be boot up with at boot time (what works in other MyBooks). In my case, the plate prevents even that my PC (Windows XP Professional) can boot at all. Therefore only 4 stars. Does the computer, however, and then closes it to them, they will be quickly recognized and working properly.
Although it is not the fastest drive of this capacity, but is not as hot as other HDDs in operation. Two 500GB Trekstor plates are my quasi "blown", because they were too hot and the cooling of the heat generated was not enough, although each disk was in itself so freely in space with 5 cm space around the device.
Conclusion: Although slightly more expensive than other HDDs, but not equal to the "large" storage solution (such as Drobo or other RAID systems), which would be recommended for very sensitive data and for me even in the medium in question is (prices for fall constantly). The WD will serve me later as backup disks for non-current data.
