henning Posted April 2, 2013 Share #121 Posted April 2, 2013 Advertisement (gone after registration) Hi Henning, Many thanks. I think your parameters for the M are pretty much optimal. On the M9 DNG compressed was always faster than uncompressed. Please, let me ask again when did you pick up your M? I am curious whether it's from the first or a later batch. Thanks again. I've had it for a month now, so it definitely is from the first batch. The dealer here sells a LOT of stuff; he sold at least 8 large Hermes sets. He got in 2 M's from the first batch.

StephenPatterson Posted April 2, 2013 Author Share #122 Posted April 2, 2013 I used 16Gb Transcend Class 10 cards in my M, formatted in camera for the following: Initial startup: ~3sec Wake w/o LV: next to instantaneous; definitely faster than .5sec Wake w LV: about .5 sec Henning This is really baffling now. Henning is using the same card as I have, and his wake times are significantly faster. Especially the Wake w/o LV: next to instantaneous is so much better than 2.5 seconds. And formatted in camera? What is going on??? Link to post Share on other sites More sharing options...
digitalfx Posted April 3, 2013 Share #123 Posted April 3, 2013 When you use SDFormater to format your cards, do you also format again in camera or use the card as formatted in the software? Link to post Share on other sites More sharing options...
StephenPatterson Posted April 3, 2013 Author Share #124 Posted April 3, 2013 When you use SDFormater to format your cards, do you also format again in camera or use the card as formatted in the software? After formatting my Transcend cards once with SDFormater and then formatting in camera to delete images the start times did not return to their previous slower speeds, but this is with very limited use and not many files written to the card.

erudolph Posted June 14, 2013 Share #125 Posted June 14, 2013 When using SDFormatter and doing the OverWrite, do you use the Options menu? Link to post Share on other sites More sharing options...
malsop Posted June 17, 2013 Share #126 Posted June 17, 2013 ....... if SD formatting is the issue then it is easily solved ...... although the sandisk I formatted with SDF4 seems actually slower than before ...... My test matches yours... I did several tests to see how long the wakeup time was in my M (Typ 240) with a SanDisk (Ex Pro, 95MB/s, 32GB) formatted in the camera. Roughly 2 seconds each time. I then tried using SDF4 (Mac Pro, Lexar USB reader) on the same SD card. That actually slowed the wakeup time enough to notice ...I'd guess that added about a half second making the wakeup time about 2-1/2 seconds. The same card was then formatted again in the M and the wakeup time went back to the original, about 2 seconds. Since my D700 takes about 1 second and my D800 takes about 2 seconds to wakeup it seems the M is in good company. In general I've found using in-camera formatting to be as good or better than can be done directly from a computer. Link to post Share on other sites More sharing options...

I noticed the similar results using the Extreme Pro cards (95MB/s) on iMac (late 2012 w/Kingston USB 3) -- Originally formatted with camera and had 2s startup-to-shot. SDF4 via Mac and quick format slowed the startup to nearly 3s. Reformatting via the camera didn't improve bring back the startup times. Attempting to format it via Mac disk Utility with FAT32 and 1 pass of zero'ing and my startup times jumped to a little over 4s. Using SDF4 with overwrite and logical assignment, my speeds returned to "normal" as 2s startup-to-shot and clearing the buffer is about 4s. Link to post Share on other sites More sharing options...
malsop Posted June 18, 2013 Share #128 Posted June 18, 2013 Garrett, This is puzzling... I wondered if perhaps deleting images from the card and not taking out the trash before ejecting the card might have something to do with this but ...no. My tests showed no difference in wakeup time when (1) the card was formatted by the M, images deleted when in card reader connected to the Mac, ejected but without taking out the trash, and put back into the M or (2) same as 1 but the trash is emptied before ejecting the card. Do they put Boot Tracks on these SD cards? Maybe someone with the appropriate software could compare these on cards that slow the M's wakeup time with ones that don't. The last time I did that kind of low-level analysis of a hard drive was on a Windows NT machine. Link to post Share on other sites More sharing options...
farnz Posted June 19, 2013 Share #129 Posted June 19, 2013 Until today I've been using a Sandisk Extreme III 8 GB card in my M240 and it's been taking about 4 seconds to boot from cold (using the skydiving method of timing: one-one thousand, two-one thousand ... etc). I received a new Sandisk Extreme Pro 95 MB/s through the mail today and it easily halves the boot time. Pete. Link to post Share on other sites More sharing options...
Guest Gilgamesh Posted June 21, 2013 Share #130 Posted June 21, 2013 Quick update. £100 worth of ScanDisc Extreme Pro 64 1/125th second DNG S: 6 actuations in 15 seconds - no improvement over the slower Ultra card. C: 21 actuations in 15 seconds - better. Write speed very good. Red light stays on for 1 second after the last shot in S In C, I get 12 shots in 4 seconds. After the last shot, actuation 21, at 15 seconds, it takes 8 seconds for the red light to cease flashing. Link to post Share on other sites More sharing options...
Lindolfi Posted June 21, 2013 Share #131 Posted June 21, 2013 Also tried an out of the box Sandisk Extreme Pro 64 GB C mode 12 actuations in 4 seconds, 21 in 15 seconds (same as Gilgamesh) Startup time 1.4 seconds (classic lightmeter, no LV). Sometimes 0.4 seconds startup time (actuation before the framelines appear) Formatted with SDFormatter, no differences in startup time and nr. of actuations after 4 and 15 seconds Link to post Share on other sites More sharing options...
pos Posted July 6, 2013 Share #132 Posted July 6, 2013 Apologies if this was already mentioned in this thread, but as a point of reference, i just recorded the sound of my M 240 starting up without an SD card inserted, LV on. Measuring from the recording, the startup time of my M 240 without an SD card inserted is: 1 second, 180ms I then inserted a freshly SDFormatter formatted 32GB Sandisk Extreme Pro 95MB/s card, and measured the sound from startup to LV on: 2 seconds 470ms I did a second recording whilst holding the shutter as the camera boots, and measured the time between the start of the turn on click and where the shutter sound begins: No SD card: 1 second, 155ms SD card: 2 seconds 750ms Link to post Share on other sites More sharing options...
lct Posted July 6, 2013 Share #133 Posted July 6, 2013 Also tried an out of the box Sandisk Extreme Pro 64 GB... Startup time 1.4 seconds (classic lightmeter, no LV). Sometimes 0.4 seconds startup time (actuation before the framelines appear)... Luck guy, i can't seem to get less than 2 secs with a Sandisk Extreme Pro 16GB card. It's 0.5sec less than with my other 16GB cards though (Sandisk Extreme, Mustang, Transcend, Samsung) Link to post Share on other sites More sharing options...
Lindolfi Posted July 6, 2013 Share #134 Posted July 6, 2013 It may be that the 64 Gb Extreme Pro is faster than the 16 Gb, or there are differences between bodies. Link to post Share on other sites More sharing options...

ski542002 Posted July 24, 2013 Share #137 Posted July 24, 2013 Hello: I've had no issues using the 32gb 45mbps SanDisk cards with my M240, although startup using the EVF is somewhat sluggish. In perusing Overgaard's site, he says that using the SanDisk Extreme Pro SDHC [sDXC for 64GB] UHS-I 95mbps memory card cuts the EVF startup in half. This card is quite a bit more pricy than the 32gb 45mbps cards and I don't really need the extra capacity unless I would start shooting a lot of video; somewhat unlikely. Any thoughts on EVF startup with the faster card? Any compatibility issues utilizing a circa 2011 MBPro and iMac running the latest Mac OS 10.8.4; Hoodman raw steel USB-3 reader? My Mac's are pre USB-3. Link to post Share on other sites More sharing options...

It's a pricy card, but compared to everything else we spend money on perhaps not really so much. I have not put a stop watch to this but my startup times seem to be just under two seconds with and without live view, although having live view off is slightly faster. Also I have not had a single lock up (touch wood) whereas with the Transcend cards it was a daily (sometimes hourly) occurrence. The other positive is that my imports into LR on my 13" MBPR are much, much faster. Link to post Share on other sites More sharing options...
