Hi all, I recently bought a G5 and like my old G3, the buffer is fairly limited. I was wondering whether the G5 would support the newest 95mb/s cards, or whether it was limited to slower cards. I haven't been able to find out for sure using Google so I've done some unscientific testing of my own. I did find tests done by Imaging Resource.com (link) and compared them to the cards that I own. The camera definitely benefits from using 45mb/s SD cards, and it appears to benefit from the 95mb/s cards as well. I also compared to my older 20mb/s cards. I thought I'd post in case others were wondering the same thing. This is the buffer clearing time shooting 20 JPEGs (super-burst mode), timed with a stopwatch. 20mb/s card = 27sec to clear buffer 45mb/s card = 18sec to clear buffer 95mb/s card = 12sec to clear buffer It was difficult to test RAW write speed because when you use faster cards you get more images into the buffer. The benefit I extrapolated looks like this: 20mb/s card = 7 RAW file buffer hard limit. 45mb/s card = 8 RAW file buffer hard limit 95mb/s card = 9 RAW file buffer hard limit. My conclusion is that the G5 does support the 95mb/s cards. Hope this helps somebody out there.
