Portable storage is getting much more interesting, with USB "thumb" drives now reaching 8 and 16 GB, and even to 32 GB (see the Corsair line for around $229).
The Kingson Technology line of USB drives includes USB memory card readers, some combined with a flash drive, plus the family of DataTraveler USB flash drives that span mini sizes to raw speed to fun styles (see previous posts).
The DataTraveler Mini is a tiny drive that's not much bigger than a USB connector, and also includes Migo software to synchronize your personal workspace to run on public machines (1 GB around $12, to 4 GB $32).
The DataTraveler Mini Fun is a colorful mini drive in stackable blocks (1 GB $12, to 4 GB $37).
The new budget DataTraveler 110 drive has a capless design with a retractable USB connector (1 GB $12 to 8 GB $104).
For faster data transfer, the new ultrafast DataTraveler HyperX has zippy 30 MB/sec. read and 20 MB/sec. write times (2 GB $74 to 8 GB $266).
Or to keep track of your data, the new DataTraveler Style features side insert "skins" to identify and customize your drives (1 GB $19, to 8 GB $116).
