FC Test 1.0 build 11

As I already said, I used two patterns to ensure a higher precision of the results. One operates with a single and large file and another with numerous small files. First, the readers will be doing some writing. Although a reader is supposed to read information, writing tests will help us estimate better the speed potential of the flash cards.

The first thing that catches the eye is the SanDisk reader being slower than the Lexar with the fastest flash cards. However, some cards (Kingston Elite pro 1024MB and Transcend 512MB, for example) are noticeably faster in the SanDisk reader. The most curious results are those of the 1GB card from Apacer: it performs well enough in the Lexar, but awfully bad in the SanDisk! I checked this result out several times, but to the same effect. What’s strange, benchmarking in the AIDA32 suite doesn’t show this phenomenon…

Let’s proceed to data read tests:

In fact, a memory card’s reading speed is not very important for digital photography applications – you can wait a bit here. Anyway, I can’t help marking the excellent performance of the SanDisk cards in this test. This is the more curious since these cards had average results in the write tests. It means that their controllers are specifically optimized for writing. We should recall here that CompactFlash flash cards have numerous applications, besides digital photography, and some of them may require high read speeds.

Otherwise, the situation with the two readers remains the same: some cards are faster in one reader and slower in another.
