With existing ML patch allowing us to record raw data to CF card and EDMAC DMA-copy having very high bandwidth (>500MB/sec), it's becoming obvious that it's CF speed that is biggest obstacle in using raw for higher resolutions and/or frame rates.
To circumvent pricey (and often temperamental) CF cards, we need reliable CF-to-SATA transfer interface.
My belief is that such device could be done.
What we need is Bi-Directional converter for serial and parallel ATA that supports UDMA-7 on PATA side. SATA side isn't important as even the lowest speed (rev.1 ) is 150MB/s which is almost as good as UDMA-7 157MB/s.
Quick Google search: here's one for 38 dollars:http://www.cooldrives.com/saidecomisat1.html
Quick check of specs:
Serial ATA 1.0 Specification compliant
Automatic Serial ATA 1.5 Gbps speed negotiation
ATA / ATAPI PIO mode 0 to 4
ATA / ATAPI Ultra DMA of transfer rate 16.7, 25, 33, 48, 66, 100, 133, and 150MB/s.
It supports UDMA-7 on PATA-side!!!
One thing that is left is to interface IDE to CF slot. Electrical specs should be the same, but physical interface differ.
Thus, we need female "faux CF"-to-PATA passive adapter. I don't know if such exist but I could make one by disassembling old CF card and soldering new lines.
Are there any other radio-shack geezers that would like to volunteer for some good-old HW tinkering?
