What's times X in MB / how to set requirements for a card
Hi -
I'm too looking for a 1GB SD card for my new X30H. Locally it's best for me to get a TwinMOS Media Store Ultra-X 1GB. There are two versions:
1) part FSD 1GBU - cheaper, R/W speed is 6/4.8 MB
2) part FSD 01GU - 25% more, R/W speed 11/7.5 MB
Firstly, can anyone tell me when someone says x times speed, what the relationship is to MB, e.g., what does 40X mean in MB R/W speed?
Secondly, what is a reasonable requirement to set for reading/writing mp3s, without a card reader, using Activesync with USB2? Perhaps the first one is good enough for me?
I suppose it's possible I might buy a new digital cam in the near future, about 5 megapixels. If I might want to use the card in that, would it be better to get the faster one now?
Basically, I'm looking for ideas on how to set requirements :) TIA.
