Flash Media: 1GB CompactFlash Roundup

Real World File System Tasks
Most users of flash media store smaller files like MP3s, pictures, and documents, which rarely exceed 10MB, so it made the most sense to test the media using 1MB, 5MB, and 10MB files. We measure the time that it takes to copy each file size to the media. Take a look at our results below.

The Kingston media is obviously the slowest here as it takes the longest to write files of all three sizes to it. Lexar's Professional series media is the quickest here with its Write Acceleration Technology only to be closely followed by Transcend's 80x CompactFlash card.

It should be noted, of course, that I am a representative of the Department of Redundancy Department. ;-)

At my workplace, we use CF cards for all sorts of things that don't involve cameras. I, for one, am happy to see random access tests. I agree that they should be in addition to sequential tests to give camera users some info.I agree that the graph types need some work. Specifically, the spline (or whatever interpolation function it is) used on page three, "Real World File Copy Test to Media," connects dots between different cards. This interpolation tells us nothing and only confuses the situation by connecting what should be disassociated information. For example, there's no information provided by looking at what the spline says occurs "half way" between an Edge and a Kingston card. If Purav were to switch the graphing inputs around such that the X-axis is file size and make separate lines for each card, then, assuming he'd picked an appropriate interpolation function for the "Real World" transfer times, we might be able to tell something about transfer times for file sizes in between the three tested. If not, then drop the spline and just plot the dots.

So where are the RAID benchmarks?mindless1 - Friday, December 23, 2005 - link
"Special thanks to NewEgg for providing us with the CompactFlash cards for this review."Yes, thank you Newegg. I love seeing reviews where Newegg donated parts, since so many of us shop there it seems a win-win for everyone.
