We have purchased five Seagate one-touch portable hard drives, to date and will ONLY buy Seagate. WD has been reliable but the others we have bought have failed, losing us much content and causing much grief. The Seagate drives are very affordable, although a trifle more expensive than some competitors but they do ship with their own cable some do not. Overall, the most VALUABLE feature of the Seagate drives is their consistent reliability. Hands down.
