The Maxtor OneTouch 4 is sold on Amazon.com and Newegg.com, as of 2016. The OneTouch 4 is a dated external hard disk drive model from 2007 that came in 500GB, 750GB and 1TB variants. It represents the last of the line of external HDDs from Maxtor, succeeding the original OneTouch and its successors, the OneTouch II and III.
The OneTouch line receives its name from the physical, one-touch backup button it sported and the accompanying software that could be used to back up information to the external hard disk on demand. The OneTouch user interface was lauded for being simple and intuitive, making data backup accessible to less-tech-savvy users. The drivers and proprietary software also used to receive periodical updates automatically, although these have since been discontinued by Seagate.
According to CNET, the Maxtor OneTouch 4 was also one of the first external drives to use USB 2.0, enabling faster, bi-directional data transfer speeds. This external drive also featured plug-and-play compatibility with Windows XP and 7, making the installation of drivers via disk or online installation package unnecessary. The simplistic backup utility was a point of contention for power users who desired more robust backup solutions. At the time, Macintosh support for this device was also extremely limited, making it an unattractive option for users of this line of computers.
