Review Image by Arron Lara
I've had this external hard drive going on about 2 months at this point and it's been an absolute life saver! My laptop was running low on storage space, and a friend had recommended I purchase this exact product and I'm very glad I decided to do so. It's incredibly simple to use, just plug it into any free USB slot you've got on your device, and it immediately starts working. The drive itself feels sturdy, and is pretty lightweight, I personally keep it underneath my laptop stand so it takes up zero desk space. It's fantastic for keeping things like videos, photos, music, and documents stored without them cluttering up my main laptop drive. Good for backing things up essentially. However, it is not great for running games or applications, whilst it is possible, applications run very slowly on it. That hasn't been much of a problem for me as I typically just use the drive for the first aforementioned uses (storing files). Overall, a great purchase, and it totally saved me from having to deal with storage shortages on my current device, would recommend! ... show more

    • NOT 1Tb and NOT RELIABLE
Capacity: 1TB Color: Black
Not only is it 70 gb short of one TB it also stops working after one day of use. It is severely corrupted even after getting a replacement from the company. The connection disconnects randomly so even trying to download a game. You will constantly get a disk error if you are installing to that drive. also judging by the connection cable it won't last very long its cheaply made. do yourself a favor and don't cheap out. buy something a little bit more expensive for a better product. ... show more
