Lexar rolls out 4GB, 8GB, and 16GB ExpressCard SSDs

We already knew that Lexar had an 8GB ExpressCard SSD up its sleeve, but it seems that the company just can't get enough of that high-speed solid state storage, today announcing 4GB and 16GB cards in addition to officially announcing the 8GB model. From the looks of it, both the 4GB and 8GB models will give a peak data transfer speed of 250 MB/s (we assume the 16GB will be the same as well), with all three coming bundled with Lexar's auto-backup software, and each ready for use with Vista's ReadyBoost feature. While the whole lot of them are supposedly shipping now, there only appears to be pricing details available for the 4GB and 8GB models, with them setting you back $130 and $200, respectively.
