The 'hardware' modem is not a true hardware modem, in spite of many vendors advertising it as such. It uses the Intel (Ambient) 536EP "Controllerless" modem chipset with on-board DSP. A hardware modem would have both the controller and DSP (with ROM) on-board. The controller functions for this modem are handled by the CPU, which makes it sort of hybrid between a software and hardware modem. Lower CPU utilization than a software modem but higher than a true hardware modem.
I would recommend it over the NetoDragon, which is a true softmodem. The Intel modem has a coupling transformer instead of a silicon DAA/hook/switch like the NetoDragon has, the latter being much less reliable or fault tolerant (surges and ESD). Intel has
recent drivers for Windows (12/8/2003) and driver support for Linux (Mandrake, Red Hat, Suse).
I'd be careful with those Foxconn readers at Compgeeks. I almost bought one last week, but in doing a little digging around, they appear to be be USB 2.0 full speed (11Mbps) not USB 2.0 high speed (480Mbps). The compgeeks description of 1.5MBps read/write rates seems to bear this out.
Indeed, good catch. Although, flash cards have relatively slow transfer rates, excepting the high performance cards. My Viking and Sandisk Compact Flash cards do about 4~6 MB/sec through a USB2.0 high speed interface, according to Sisoft Sandra's Removable Storage Benchmark. I'm not sure how other card types would fare.
1.5MB/sec will be a bottleneck, but to what extent and is it tolerable...
