elliot1 Posted December 27, 2014 Share Posted December 27, 2014 <p>Have you used both? Do you find a noticeable difference between the write speeds of the two with the OMD-EM1?</p> Link to comment Share on other sites More sharing options...
chrisnielsen Posted December 29, 2014 Share Posted December 29, 2014 <p>Hi</p> <p>I have the E-M1 and was having trouble with it locking up for extended periods after shooting continuous, so I checked out my SD card and found it was only rated at 10 mb/s. I bought the Sandisk 95 MB/s card you are talking about and ran some tests. I don't have the 45 mb/s card but you can draw your own conclusions.</p> <p>Apacer 10mb/s card: 35 RAW images captured in 5.5 seconds before it slowed down, then continued at 0.69 fps. Burst was approx 10 mb/s.<br> Sandisk 95 mb/s card: 53 RAW images captured in 7.8 seconds before it slowed down, then continued at 2.9 fps. Burst was approx 90 mb/s.</p> <p>From this, you can see that the camera is well able to make full use of the rated transfer speed, I would guess the 45 mb/s card would be somewhere inbetween the above two figures. I understand the camera can not support >90 mb/s so buying a fancy 280 mb/s card would be a waste of time. I also see even the 90 mb/s card can not sustain that speed for long - once it drops to 2.9 fps that is pushing through a constant 30 mb/s according to my calculations - does that mean the fast card just has a fast cache?</p> <p>Also I noted in the test that the time to clear a burst went from 48 seconds to 12 seconds, and of course the E-M1 prevents you from entering playback mode while it is clearing the buffer - good enough reason to get the fast one IMHO. Also, 2.9 fps is how fast my first airshow camera was, so in my situation it's fast enough even after burst mode has been expended, to continue shooting at 2.9 fps - it's quick enough for me that I have effectively an unlimited 3 fps RAW recording capability which makes me jump for joy compared to my old 30D in particular</p> <p>Hope this helps.</p> <p>Cheers,</p> <p>Chris</p> Link to comment Share on other sites More sharing options...
elliot1 Posted December 29, 2014 Author Share Posted December 29, 2014 <p>Thanks, that is the info I was looking for. Your results do show improvement over my older cards. I guess I will be buying some new cards. Much appreciated!</p> Link to comment Share on other sites More sharing options...
elliot1 Posted January 1, 2015 Author Share Posted January 1, 2015 <p>I am expecting the new cards next week and will do some testing and report the results.</p> Link to comment Share on other sites More sharing options...
elliot1 Posted January 10, 2015 Author Share Posted January 10, 2015 <p>I received the cards I ordered and they are indeed twice as fast as my older extreme cards with speeds in line of what Chris reported. Highly recommended!</p> Link to comment Share on other sites More sharing options...
