Here is an out-of-the-box solution for turning those high capacity Compact Flash memory cards into SATA hard drives. The CF to SATA hard drive adapter is ideal for using CF as a bootable device containing OS or application data.

The adapter is compatible with Compact Flash type I and II and will provide a full functioning SATA interface.

The adapter card is also fully compatible with Windows XP, Vista and Linux - in case the application is something other than embedded.

The CF to SATA adapter is $25 without power supply and $35 with power supply so a reasonable price for what you get.
