Type 1 and type 2 normally refers to the thickness of the CF card (3.3mm vs 5mm) so is probably the wrong term to determine if its a burst mode type card or not. Testing and reporting the results here may be our only way to tell what cards work and don't. Most manufacturers don't even report that.
Good points about card types, so no easy way to identify use of 'acceleration' schemes. Maybe a card's lack of minimum sustained write speed specification is a better indication of using burst protocols that may not work well with all audio decks.
By reading all the articles referenced so far, camera write and file-to-file transfer speeds in various readers is what has been well researched, not continuous real-time write ability typical of recording audio to flash.
And it's becoming clearer that various audio decks, like the flash cards, use variations of controller protocol, so NO WAY to generalize on what type of flash card will always work for specific audio recording purposes. As suggested, only by testing individual deck models running in the low-to-high resolution modes with particular flash models can any conclusions be made on full compatibility.
Audio recording to flash is relatively new, and unless deck makers get more responsible in flash testing for compatibility, we may need to continue to post personal experience with deck/flash card models to get a handle on what works reliably, and what combination is problematic.
Suggest we start posting experiences including the following (needed) information:
1. deck model and firmware version
2. file type recorded (bit depth/sample rate of mp3/wave)
3. flash make/model and capacity
4. freshly formatted flash or not
5. type of audio input (analog or digital)
6. Does the card always work, or not?
Example:
My current experience is limited to MT deck model:
running version 1.2.3, and freshly formated 'regular' Toshiba CF 2-GIG card seemed to worked great for <24bit/48K analog input recording, but caused severe stuttering at higher definition rates. MT v1.2.3 had trouble formatting (too slow?)Toshiba CF giving error in system memory capacity, but v1.4.0 seemed to solve reported formatting problems.
Regular Kodak 1-GIG CF seemed to do everything right regardless of audio file type or firmware version on this deck.
Much experience with Sandisk Ultra II 8-GIG; seems quite reliable regardless of audio file type, after successful format. Initial format failed as the deck would not recognize the card until a few boot and flash insertion cycles resolved some kind of conflict; using version 1.4.0.
So far, I have not heard of anyone running at least MT deck having compability problems with Kodak or Ultra II flash.
It would really be nice to have a list of NEVER A PROBLEM FOR AUDIO IN ANY MAKE/MODLE TYPE OF DECK list of flash memory products.
Maybe we should start a list with check boxes, or something like that, where (non-defective) make/models of flash could be polled to be trouble-free from virtually everyone's experience regardless of deck and audio file type?
Something like this:
Sandisk Ultra II; anyone had a problem?
YES NO
ONCE FEW TIMES OFTEN NEVER WORKED
DIGITAL ANALOG (input)
MP3 <24BIT/48k >24BIT/48k (check all that apply)
R-1 R-4 R-09 MT2496 SD702T (partial list of deck models)
With tapers reporting experiences on the various models of decks and flash in an organized manner, it may not take too long on getting a handle on what's important to know for having flash work just as reliably as analog cassette, digital DAT, and the more recent hard disk decks.
