Hi All...

Using my logic analyzer (I love this thing) I measured the time required to close three files, including the overhead of a function call, at 13 uS. This is using SDFar on a 12MHz 1284P and Arduino 1.0.

Does that sound right? It seems pretty quick.

Depends how the driver's written - you have the source code so you can go and have a look if you like.

I think its more likely to depend upon the card. I am thinking in any case, its plenty quick so that if i can keep the board up for something like 100 or 200 ms I should be fine.
