PIO modes 5 & 6 were added to the CF Specification as host system designers were asking for faster PIO mode transfer rates. Current technology allows for the faster timing that is required. Currently the CFA does not intend to bring a proposal for PIO modes 5 & 6 to the T13 committee. The CF Specification does include UDMA 33 & 66.

This message is from the T13 list server. T13 has no plan to add PIO modes 5 and 6 to ATA8. This was discussed during the last year, and the group saw no need to add it. If, on the other hand, the CFA wants to bring a proposal to T13, we would look at it. Please also remember that CFA does not have UDMA, and is based on ATA/ATAPI-5.

I've recently downloaded a document for a Compact Flash card that shows operation in PIO mode 5 (20MB/sec) and mode 6 (25MB/sec). Is there a proposal to increase the PIO transfer rates for the IDE interface? Was there a proposal at one time? Am I a victim of marketing? :-) Thanks, John Sherman Astek Corporation
