I have noticed that there's such CF card adapter that can allow SD card to be inserted, so if I have a Hi speed 10mbytes transfer rate SD card, inserting into such CF adapter, will it be also allowing full 10mbytes transfer or write speed that is stated accordingly for the SD card? anybody has tried using these CF card adpater? can pls share whether this is a reliable adapter device as a alternative solution if I have a camera that only allows CF type I and I only currently have a SD card and not deciding to sell it off or buy another true CF card. Thank you.
