Disappointing V1 writing speed test

I have tested two of my SD cards in my V1.

Card: Sandisk Extreme Pro 95MB/s 16GB
RAW:

  1. Took 45 RAW in 8,8s before slow down, finished writing to card in 39,6s., 320.303.703 byte ~ 305,5MB ~ 7,71MB/s

  2. Took 45 RAW in 8,4 s before slow down, finished writing to card in 47,1s., 377.551.822 byte ~ 360,1MB ~ 7,64MB/s

JPG:

  1. Took 62 JPG in 12,1s before slow down, finished writing to card in 38,8s., 254.853.590 byte ~ 243,0MB ~ 6,26MB/s

  2. Took 60 JPG in 11,9s before slow down, finished writing to card in 37,2s., 245.876.017 byte ~ 234,5MB ~ 6,30MB/s

Card: Sandisk Extreme Pro 45MB/s 8GB
RAW:

  1. Took 45 RAW in 8,8s before slow down, finished writing to card in 48,38s., 376.643.401 byte ~ 359,2MB ~ 7,42MB/s

  2. Took 44 RAW in 8,5s before slow down, finished writing to card in 48,93s., 368.736.073 byte ~ 351,7MB ~ 7,19MB/s

JPG:

  1. Took 60 JPG in 11,6s before slow down, finished writing to card in 39,58s., 245.546.639 byte ~ 234,2MB ~ 5,92MB/s

  2. Took 60 JPG in 11,4s before slow down, finished writing to card in 39,64s., 246.490.392 byte ~ 235,1MB ~ 5,93MB/s

So you only gain very little using 95MB/s instead of 45MB/s SD cards, of course you can read faster at your computer if it's supported. Really disappointing results for the V1. Nikon have probably used a slow memory controller for the writing to card operation. We could hope for an improvement through a firmware update, but I doubt Nikon will/can do it.

It should be noted that the V1 is only locked 1-2 seconds after you release the shutter button after the first series of 45/60 pictures is taken, and can take at full speed again until the buffer is filled again. Also the buffer size is excellent.

As a comparison my D300 writes 30,3MB/s (RAW) and 27,2MB/s (JPG) with Sandisk Extreme Ducati CF cards which is a 45MB/s card AFAIK.

Ole,

I opened up a support call with Nikon last friday on this issue. It is already forwarded to the development team for feedback. I'll share when something comes back.

Excellent Andy, it's so nice to have some proactive Nikon 1 users instead of the usual grumblers like me

Not surprising

I don't know of any cameras yet that supports the full speed of 95mb/s. The D7000 and X100 have the same issue where there is less than a 10% gain going from the 45mb/s card.

Basically don't bother spending the money on the higher speed card until the camera manufacturers catch up.

Thanks Ole and Andrea

That must explain the lock up.

Re: Thanks Ole and Andrea

Can you try this.

Go to any online timer that generates time in secs. Synchronize the time with V1.

Focus on the computer screen, fire at continuous until the camera locks. Record the files creation date in exif.

Plot this on a chart.

Vary the test using a cheap card and shooting with electronic shutter.

Its unscientific but the results should be interesting.

LOL ! that's why I followed...

...what you answered to me in the "fastest SD card" thread I wrote last week !

I got myself 2 Sandisk Extreme Pro 45MB/s 8GB instead of 1 95Mb/s 16Gb. !!!

...but I haven't had the guts to compare with the first Sandisk ULTRA 15MB/s 4GB I had bought together with my J1 !

Thanks again for the tests !

J-P.
