Units exchange storage for portability
Storage maker Lexar has announced two upcoming backup drives, the Echo MX and ZX. Although offering less storage than conventional backup options, the drives are essentially USB sticks, making them significantly more portable. Each contains automatic backup software offering 128-bit AES encryption of data.
The ZX is the low-end device, coming in 8, 16 or 32GB capacities. The 8GB model has peak read and write speeds of 28MBps and 10MBps; writing goes up to 15MBps for the 16 and 32GB options. MX buyers can choose between 8, 16, 32, 64 and 128GB sizes, which are limited to 28MBps read and 10MBps write on smaller drives, but offer up to 30MBps read and 17MBps write by the 128GB level.
The MX design also sports an always-on capacity meter. It should arrive sometime in the first quarter of 2011, while the ZX is due in the spring. MX models will range in cost from $45 to $500; ZX prices should fall between $45 and $140.
