 Nikon D70 JPG File Testing |
Source: PCStats |
| |
The Nikon D70 is
another digital SLR camera with a resolution of 6.1 Megapixels. It is the newest
of the two SLR cameras we tested, so we were interested to see if its maximum
transfer rates were higher than the 13x speed that the FujiFilm S2 Pro was able
to achieve.
The camera was set to continuously shoot at
a static target until its internal frame buffer was filled. We timed how long the writing
indicator light was on and calculated the bandwidth of the CF media by the size
of all the transferred pictures divided by the time it took to store the data.

The Nikon D70 digital SLR is a newer and more advanced
camera and does not wait for the frame buffer to fill before writing data to the
CompactFlash card, which is why we see such a big difference in the number
of pictures and total file sizes. While lacking an advertised speed rating, the Crucial CT1GBC1 CompactFlash card
puts in a good showing here and is only slightly slower than the high speed Kingston
Elite Pro and Sandisk Extrene CompactFlash memory cards. The Centon card does manage to exceed the
10x speed cap it seemed to have when tested with the FujiFilm S2 Pro camera.
The IBM Microdrive posts a speed marginally faster than with the FujiFilm S2 Pro digital camera.
It is surprising to see that while the Corsair CMFCF80-1GB is the fastest
Compact Flash card, it can only take 20 pictures while the slower Sandisk 1GB Extreme
does 90.

In RAW testing, the Nikon D70 stores data in a
compressed proprietary format which will later be uncompressed
when the data is transferred from the camera to the computer. Because
of all this extra work, the Nikon D70 is only able to burst shoot four
pictures and compression does take its toll on overall bandwidth. Still we see quite a
difference between the various CompactFlash memory media. The Centon and Crucial CF cards
have a strong showing here, while the Corsair CMFCF80-1GB leads the pack with an
effective speed rating of 25x.
Up next, we see what Sisoft Sandra 2005 has to say when it comes time to pull
those photos off the cards and onto a PC...
