From what I have read, SanDisk (and others) are using a new rating system, reflecting the minimum rather than the average or maximum trasfer rate of the memory cards. So they are saying the new 16GB cards, rated as Class 2 will have a minimum transfer rate of 2mb/sec, but can (and usually) transfer at a much higher rate, making it comparable to the previous Class 4 card. There hasn’t been any rumors that I’ve heard or read that indicate that a faster card is in the works (but who knows, SanDisk plays it pretty close to the vest).
Also the refresh time it takes is dependent on the number of files, not the size of the content. If you have 1000 songs, it’s going to take much longer to refresh than if you have for example 4 movies.
The refresh happens when there is any change in the file structure residing on the card. This includes changing cards, but more importantly to the majority of users (myself included), everytime you un-plug your device from the computer after adding, deleting, or changing files.
I don’t have a card in my Fuze, but with my e280v2 (8GB) and an 8 gig card making 16GB total, it takes a full 5 minutes for a DB refresh everytime I disconnect from the computer after changing something on either the player or the card. Adding a playlist, swapping files from one memory to the other, diagnostics trying to help someone here on the forum, etc. Both my player’s memory and card are virtually full (less than 20 MB on both combined).
I can only imagine the time it will take when I get a 16GB card and have to wait for a 20-24GB refresh! Not something I’m looking forward to. I’ll probably have time to call Dominos for a pizza while I wait! :smileyvery-happy:
