I have a positive experience with Western Digital, I use MyPassport, Elements, MyBook and some older ones can't even recall the name. So far I had no faulty device. My friend had one, the external case and the electronics failed, the disk inside still worked -- that was a dual disk one with some kind of hardware dual raid and eSata plus Firewire ports as well as the usual USB 2.0. He gave that case to me if I want to fix it for myself, but I had not got the time to see if repairable. By the way, I have never used the internal software as that is for Windows, andI use Linux and Mac. Mac has a very nice automatic backup system coming with the operating system, so that's fine, whereas with Linux you have million plus one choice of free and commercial solutions, and if you do not like any of them you can still do that by yourself using few command lines. Anyway, as with the port choice, USB 3.0 is way faster than 2.0, so if you have a chance to place a new card into your dekstop then I would do that if I were you. Other option could be a network drive - it has a gigabit ethernet, so you can use it from many computers using the network, plus faster than USB 2.0. Some also supports Internet access, for example WD Personal Cloud Storage is like that, you will be able to use your own storage from anywhere even from your mobile devices. http://www.wdc.com/en/products/network/networkstorage/ if not, you might can consider an external disk with Firewire port in it. One of the MyBook I have had a FW-800 port, but my old laptop only supported FW-400. 400mbps vs. the USB 2.0s 480mbs, still 50% faster when you copy large data, and FW-800 would double that speed. Oh, and FW is daisy chainable, no need hubs to attaching more disk. That MyBook of mine with the FW port on it also has eSata, many laptops and desktops has that too. That is even better meaning faster. I think that is called Studio II. Btw: If you had a newer Mac, you could consider the Thunderbolt which is also can be used in daisy chain. http://www.wdc.com/en/products/external/desktop/ If you select the "Portable" ones from the menus, those are the small ones that does not require external power source, only the USB. Apart from the portability I can't see any advantage for those plus more expensive.
