I need a USB external hard drive for my computer and I am looking for a reliable company which comes with the best USB external hard drive. I need to carry some more data with me and it is not possible to carry in data traveler. I am looking for some more details about the USB external manufacturers. Though I have gathered some details about the Seagate and Western Digital which all are offering the device at very smart prices, but it is not sufficient to compare the devices. So guys, please make the USB external hard drive detailed with more words. Thanks.
