Nikon D7000 Memory speed tests, SDHC Memory Cards: including Sandisk Extreme Pro UHS Speed Class 1 45MB/Sec and Several Popular Class 10 SDHC Cards

Sandisk Extreme Pro SDHC 45GB-Sec 8GBSo, the D7000 DX sensor format camera body has a hundred shot built in memory buffer, right?

Not exactly, this buffer size, in number of pictures depends on photo quality.

When shooting High Resolution RAW Nikon NEF images in 14 Bit depth, the D7000 can only story 10 shots in its built-in buffer.

Memory Buffer Capacity:

  • 1o shots, NEF RAW 14 Bit Lossless Compressed
  • 11 shots, NEF RAW 12 Bit Lossless Compressed
  • 12 shots, NEF RAW 14 Bit Compressed
  • 15 shots, NEF RAW 12 Bit Compressed
  • 31 shots, JPEG Fine Large
  • 100 shots, all other JPEG  qualities and file sizes

For me, it’s the highest resolution available of 14 bit lossless compressed I am shooting in.

Why some may shoot in most of these other modes with such a high end camera is beyond me.

Using 3 different memory cards I ran the following side by side tests:

  • Set camera on high speed burst mode
  • Set focus on AF-C, no time needed to focus, camera shoots when shutter button is depressed
  • Press in and hold shutter release for 20 seconds

What was measured:

  • Total number of shots taken
  • Total time to write the total shots taken to memory cards

TEST PERFORMANCE RESULTS

  • Transcend 32 GB Class 10Transcend 32GB SDHC Class 10
    • 20 images total
    • Total time to write 42 seconds
      • 20 seconds shooting
      • 22 seconds to write final 10 images to memory
    • Buffer fills in about 2 seconds
    • Shutter freezes for about 3-4 seconds, then two more shots are taken by camera, and so on
    • Currently $55.42 (May, 2011) [WAS $50.55 Feb, 2011]
  • 8 GB Sandisk Extreme Pro 45MB/Sec UHS Speed Class 1
    • 34 images total
    • Total time to write 27 seconds
      • 20 seconds shooting
      • 7 seconds to write final 10 images to memory
    • Buffer fills in about 2 seconds
    • Shutter freezes for less than 2 seconds, then two more shots are taken by camera, and so on
    • Currently $36.29 (May, 2011) [WAS $42.76 Feb, 2011]
  • ATP ProMax 16 GB Class 6  (No Longer Available Nov, 2011)ATP Pro Max Class 6 SDHC
    • 20 images total
    • Total time to write 42 seconds
      • 20 seconds shooting
      • 22 seconds to write final 10 images to memory
    • Buffer fills in about 2 seconds
    • Shutter freezes for about 3-4 seconds, then two more shots are taken by camera, and so on
    • Currently UNAVAILABLE (May, 2011) [Was $79.99 Feb, 2011]

Let’s review:

  • The Class 6 ATP ProMax versus the Class 10 Transcend had same performance results in this testing.
  • The difference between the Class 10 Transcend and the UHS-1 Sandisk Extreme Pro 45GB/Sec was mainly in time it took to clear the camera buffer.

Once the internal camera buffer was totally full, the Sandisk was able to totally empty the buffer and be ready to reshoot the entire camera buffer after only 7 seconds, and could shoot a couple more frames after only 2 seconds of writing out the buffer…

The other two cards needed 22 seconds to fully clear a full camera buffer and would require 4 seconds before any further shots could be taken at all, once the camera buffer became full.

There is a max continuous release setting in the Shooting Display – item d7 on the Nikon D7000 menu.

If one were to set this to some number below 10 shots and one were to take a little break between bursts, you might get several bursts in without over running the D7000 10 shot buffer.  The Extreme Pro would aid greatly in this pursuit of multiple high speed burst shoots.

Using fast memory like the Sandisk Extreme Pro seems a must do for anyone wishing to shoot action and live sports in continuous burst modes or for repeated bursts. In these applications, the UHS-1 (UHS-I) Speed Class Memory Cards seem the best available SDHC alternative.

This might be compared and contrasted with someone not interested in shooting a lot of bursts, where here the Transcend’s 32 Gig storage capacity at a low price gives a lot of memory space for not a lot of bucks.

Prices on these fast SanDisk UHS-I memories have been falling, even as the slower memories are becoming unavailable and/or have been rising in price.

So, be sure to check the current pricing.

It may be lower than you think.

For example, for a larger fast memory, which was $149.95 in February, 2011, the 32 GB Sandisk Extreme Pro 45MB/Sec UHS Speed Class 1 is available currently for $139.72 (May, 2011) at Amazon by clicking here.

To check out the Nikon D7000 body only, as of May, 2011, Amazon price in stock, bounces between $1199 to $1349 daily, and with an indeterminate wait at Adorama seems stable at $1199.
