#9. "RE: SD Card speed question" In response to In response to 8
St Petersburg, RU
Actually, the gate array inside the CF card is used for "wear leveling", moving data to less written to sites to even out write cycles totals over time. Since the cell is write limited in life, a concentration in writes to the same cells would shorten the life a great deal for the entire card. Wear Leveling and EC&C slow down data I/O, instead of improve throughput. The CF standard is not getting the development attention that more mass appeal cards like SD due to the gigantic volume potential of the smaller cards. Quite likely the CF cards will be phased out in the not too distant future because it is large and has a small target audience. Most limited distribution items become obsolete due to consumables not being available eventually. When you can't buy recording tape, your $85,000 Studer, built-for-ever, multi-track tape deck is simply a large door stop, for example. The same will occur to 15 year old top pro digital cameras.
