UDMA rating The UDMA rating determines the maximum bus speed at which a card can read, assuming the memory in the card is fast enough to match it. UDMA 1 supports speeds up to 16.7 MB/s. UDMA 7 is ten times that speed, maxing out at 167 MB/s. This is the minimum sustained write speed—the slowest the card will write.
Similarly, Are CF cards obsolete? Is the Compact Flash card obsolete now? – Quora. No, not necessarily! Sure, for me the use of CF cads ended around 2005, when I got to digital cameras that used MMC or SD cards, or xD cards instead of the much larger Compact Flash cards.

Beside above, What is the difference between CF Type 1 and Type 2? The only difference between the CF Type I and Type II memory cards is their thickness. CF Type I card is 3.3mm thick, while CF Type II card is 5mm thick. CF Type I cards can fit into CF Type I and Type II slots, whereas CF Type II cards can only fit into CF Type II slots.
