Hi all,
Every now and then somebody asks about the possible speed advantages of Sandisk ExtremeIII cards with the E-1, and always somebody quickly points out that the E-1 cannot take advantage of the ExtremeIII's speed advantage over the UltraII.
However, has somebody ever tested this? Or is this just 'common knowledge' that is repeated so often that it has become the truth?
I cannot not remember seeing any concrete evidence for this statement, at least not using firmware 1.4, which specifically addresses support for 'New high speed CompactFlash cards' (from Olympus documentation). In fact, the only measurements that I have found using the search function of this forum indicate that ExtremeIII cards are indeed faster! The measurements were taken from a magazine test, duplicated in this post: http://forums.dpreview.com/forums/read.asp?forum=1022&message=15225022
Those results indicate a writing speed of approx 4.6MB/s, significantly higher than the 3.3MB/s figure that is obtained with UltraII cards.
So, all we need now is somebody on this forum with E-1 (firmware v1.4) and an ExtremeIII card to verify these results. The easiest procedure is as follows:
1. Set the E-1 to continuous drive mode, manual focus and manual exposure with a fast shutter speed.
2. Press down the shutter release button until the buffer is filled (12 shots)
3. Measure the time between the intial button press and the moment the CF-write light turns off.
4. Calculate the write speed as 12*10.1MB/T sec, where T is the time measured in (3).
I would be happy if someone could perform this simple test to settle this issue once and for all. Thanks in advance!
