CompactFlash Card Roundup: 1GB Models - PCSTATS
Abstract: Buying the right CF card for your digital camera can be difficult, well mostly confusing since there are size, type and speed considerations to wrap your head around first.

Nikon D70 Testing

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...
