Lexar Media, Inc. has launched its ExpressCard Solid State Drive with auto-backup software. About half the size of a PC card, the Lexar device plugs directly into the ExpressCard slot of a notebook PC.
It comes in capacities of 4GB, 8GB and 16GB. Its auto-backup software allows for automatic regular (daily, weekly, or monthly) backup without user intervention after the initial setup.
The company says the Lexar ExpressCard SSD takes advantage of ReadyBoost, a Windows Vista feature that improves system performance without having to add DRAM to the computer.
The ExpressCard SSD serves as an additional memory cache, which is a reserve section of memory that the computer can access faster than if it were accessing data from the hard disk drive, according to Lexar.
There is a report however that the Lexar SSD reads only at a fair 15MBps and writes at a sluggish 3MBps, compared to one laptop drive that churned about 30MBps for both read and write.
