DR1000 SDHC class 10 SD card is compatibile?

bokjeid · 09-17-2010, 03:05 AM

Somebody uses this type of SD card in DR1000S? I found it out that some class 6 is no problem but there was nothing about class 10 in this forum.. Now I'm about to buy one.

That class x stuff is about the max transfer speeds supported, no? Don't the higher class ones always support slower speeds too, possibly even all slower speed settings? I've not heard before of a device that can't read a particular card because it is too high a class. (Any issues tend to be about the storage capacity and the file system needed to fill such a size.) As far as I know you just don't benefit from the extra speed, as the effective speed is determined by the slowest of the two devices (card and reader) involved.

Yes, it is said that class 10 means 10mb/s. Well, I ordered a SDHC class 10 SD card which I mentioned here and I'll post the result later - how it works or performs!

I tried one, it works. There are no speed benefits however. It actually seems slower, but that may also be related to the capacity (32gb) rather than the speed rating/controller. (I don't have it on hand right now to give you the exact make & model)

OK, I'll also try it after I get it and check the speed.

Now I checked the speed with a benchmark program and attached the result image, which says that the reading speed is about 4mb/s and the writing speed is about 2mb/s.
So I decided to buy SD card reader for it. I assume moving SD card seems easier than moving USB cable to copy something from PC to SD card of DR1000S, for me.

I updated the thread! And my transcend SDHC class 10 8GB SD card is working well with DR1000S.
