chris_tribble Posted September 12, 2009 Share #1 Posted September 12, 2009 Advertisement (gone after registration) I've just ordered some 8GB Sandisk Extreme III cards as these give a 30MBS write time - but I've just noticed on the M9 FAQ that Leica rates the Extreme III 4GB as slower than the Ultra - a mistake? Any thoughts...? Link to post Share on other sites More sharing options...

RobertW Posted September 12, 2009 Share #2 Posted September 12, 2009 Seen some threads indicating the Sandisk Ultra II are considerably faster.... Best Rob Link to post Share on other sites More sharing options...
stevelap Posted September 12, 2009 Share #3 Posted September 12, 2009 There's an ongoing thread on this Chris, with some interesting comments and tests http://www.l-camera-forum.com/leica-forum/leica-m9-forum/98109-sandisk-sd-card-speeds-m9.html Link to post Share on other sites More sharing options...
scott kirkpatrick Posted September 12, 2009 Share #4 Posted September 12, 2009 Maybe not a mistake. You'll certainly be able to upload the Extremes in half the time it takes to upload from the Ultras. (But they cost two or more times the Ultras, which are spec-ed at one-third the upload speed.) The issue is whether Leica will figure out and be able to fix what seems to be anomalously slow write speed to the faster cards. Both Ultras and Extremes are spec-ed to be able to read 38 MB in about 4 sec and 18 MB in 2 sec,l but so far only the Ultras are actually taking data from the M9 at that speed. Recently different people at leica have given different answers (trust the FAQ; buy the faster cards) to different people. I think they are probably still working on this. scott Link to post Share on other sites More sharing options...
HankBar Posted September 12, 2009 Share #5 Posted September 12, 2009 THe M9 seems more picky about cards than the M8. When I bought the M9 I had a card I used in the M8 with me (ADATA, 8 GB). It did not work, so I bought in that shop another one, Lexar 8 GB. It worked. But when I tried to delete all the pictures (only 8 at that time), the red light keeped flashing for a 5 minutes and when I tried to end it, , the camera could not be turned off. Finally, when it stopped, nothing has happened and I had to delete the pictures one by one. I do not know what is going on and will try some other cards.

toke Posted September 12, 2009 Share #6 Posted September 12, 2009 I used sandisk ultra 11 2Gig in M9, with no problems at all....... I can take 6-7 photos before the camera needs to transfer data. I can take 11-12 with M8 and same card. Link to post Share on other sites More sharing options...

I can take 11-12 with M8 and same card. Since you've got a real production model (with 1.002 firmware, right?) would you mind repeating the timing test that I tried with an Ultra II 1GB on my M8.2? Find a clock with a sweep second hand, shoot it close enough so that you can see the elapsed time by reviewing on the LCD afterwards (don't waste your hard disk space on this stuff). Set DNG (uncompressed) and no JPEG, and hold the shutter button down in C mode for about 15 shots. Review to see how long each shot took. You should get the first 6-7 shots in about two per second, so the first question is how many seconds and how many shots elapsed before things slow down. Then see how many seconds elapse between each shot once the buffer is full and you are continuously writing to the Ultra card. If the second hand motion is jerky, you can wait for 5-6 more shots and measure the total time. Finally, when you stop shooting, wait until the red light stops blinking and shoot one more time to record the total time to clear the buffer. If you do this, and save the timings you will have a good baseline for comparing the speed of different cards in the M9 and for telling if new firmware has given us improvements. good luck, scott Link to post Share on other sites More sharing options...

Had the same issue with a Sandisk once, looks like a firmware glitch to me... Best regards, Michael Link to post Share on other sites More sharing options...
