Lexar Media has announced that it will release the largest CompactFlash memory card yet, with a whopping 4 GB storage capacity. It has also created a 2 GB one which will be available much sooner. These cards are capable of a minimum sustained read and write speed of 4.8 MB per second. The 2 GB CF card will be Type I and expected to retail in March for $700. The 4 GB card will be Type II and is expected to ship in the second quarter for $1,500. On a related note, Soft Pocket Solutions has announced that it is developing a driver that will allow the Sony Clie NX series and the NZ90 to use CompactFlash memory cards. This driver will allow a CF card to essentially act the same as a Memory Stick does.
