Thanks for testing the A-Data Speedy 533x card. I bought one recently, but hadn’t unwrapped it yet. Looks like it’s going back in favor of something faster!

Some of newer Kingston CF 133x memory cards support UDMA mode 4 but it still sucks in sequential write speed with only 15MB/s on PC IDE bus with proper cluster alignment.

Sandisk Extreme III (new version) is UDMA mode 2 (bus speed 33MB/s) CF card.

Also cluster alignment operations on the partions and file systems of flash media are very likely to add even +50% sequential write speed. It is usefull for MLC flash, low-end storage media are MLC.

Please note that CF speed in cameras are also limited by transfer modes. The way of negotiation transfer mode is a magic in most non-PC devices. Most popular transfer modes for PC are PIO 0-4 nad UDMA 0-6 while cameras utilize PIO 0-6 (and coresponding multi-word DMA 0-6) and sometimes UDMA 0-4.

I’m looking for one of the new Extreme III’s to try out. SanDisk upgraded the Extreme III line to UDMA recently, but there are still plenty of the older versions out there.

If I look at Rob Galbraith’s data, the Sandisk Extreme IIIs are near the tops in terms of performance. Given the relatively lower prices and rebates out there now, they seem like a great deal. Have you tested the Extreme IIIs with the D300?
