I have one of these 2GB jobbies:
http://www.pcconnectionexpress.com/1/1/2843759-transcend-information-transcend-2gb-44-pin-vertical-ide-flash-module-ts2gdom44v.htmlI have no idea if they are really any different than a CF card. Mine works great as a hard drive. Other stuff on the page there might look at...
Fast? Well it faster than any moving parts ide drive will ever be, I'd confidently guess.
EDIT
I don't know what this stuff means really:
http://www.transcendusa.com/Press/index.asp?LangNo=0&axn=Detail&PrsNo=529Transcend's IDE Flash Memory Module is small in size, measuring just 59.0mm x 27.3mm x 7.3mm (plastic case included in package) and has strong data retention. The 44-pin IDE Flash Memory Modules is ideal for use in harsher more demanding industrial environments where PCs, Set-Top Boxes and other industrial machines are used. In addition, with built-in ECC (Error Code Correcting) functionality Transcend's IFM ensures highly reliable data transfer and also supports Auto Sleep and Power-Down modes to save on energy.
Transcend insists on only using original SLC (Single-Level-Cell) NAND Flash chips in its IFM's, which have higher write speeds, lower power consumption, and superior durability compared with IDE Flash Memory Modules made with MLC (Multi-Level-Cell) chips. Transcend's 2GB IDE Flash Memory Modules are extremely reliable, have hi-speed data transfer rates and are the perfect choice for use in your industrial machines.
EDIT ...
Found some new kinds, "high speed" supposedly:
