Because the characteristics of mobile hard drives, buy 8M cache; it hard to read and write in reducing the number of great help (such as 16M of data, 2M hard to read eight times, and hard-8MDisk read only 2) also can be extended hard drive life. 4. Never buy a 7200 rpm, high speed but will shorten the life of mobile hard disk. More than 5400 speed had little sense - because this time depends on the hard disk transfer speed USB2.0 interface, not speed up5.
