HDTach 3 RW

HDTach 3 RW provides us with information regarding the average read and write rates for each media.

HDTach 3 RW - Average Read Rates

HDTach 3 RW - Average Write Rates

Lexar drops a few positions here as SanDisk's Ultra II card performs the fastest in HDTach's Read and Write Rate tests giving us 8.1MB/sec and 7.8MB/sec respectively. Transcend also gives us some consistent results at 7.7MB/sec read rates and 7.3MB/sec write on its CompactFlash card. You may wonder why the EDGE brand card is not on the list. For some reason HDTach could not complete a benchmark on that card while all other tests completed successfully. We'll see later that its performance was, overall, pretty good for a mid-performance card.

    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?

    "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.
