Has the world moved on from CF? I always thought that was supposed to be a bit easier to
interface to - i.e. SCSI->IDE bridge, IDE-CF adapter, done. Maybe there are just
various gotchas that make SD more attractive?
I think CF is the better card by far, from a technical
standpoint. However, SD has the advantages of a
significantly lower pin count and wide support among
modern microcontrollers. Newer industrial designs
that would have used CF in years past are beginning
to migrate to CFast, a newer reimagining of CF that uses
SATA as a transport layer instead of ATA.
You could interface CF with a modern micro's memory bus
(in fact, some have features which facilitate this even
beyond the ATA interface), but it requires a lot more
pins and more legwork on the software side.
