So, has anyone noticed a difference for things like playing movies, music, etc. off on a class 4 card versus a class 6?

I'm asking because of the cost/space differences. I'd like to get a 32 gig card for the extra space, but if a class 6 is much of a difference, then I'm wondering if I should wait for a class 6 32 gig or just pop for a 16 gig one now or what.

Primarily, my wife will be using this to watch Thai/Korean movies she's downloaded while she is on dialysis 3 days a week. The rest of the time, I'll be using it mostly for the book I'm writing.

I don't buy anything but class 6 because people who used class 4 cards in their Nokia N800 Internet Tablets experienced corruption problems. Also, class 6 devices can be significantly faster than 6MBpS. For instance, I have a Transcend 8GB class 6 card in my Mini 9 and I just tested it with CrystalDiskMark and it has a read speed of 24mbps and a write speed of 9.9.

If you get a 4MBpS card, and if it is too slow, you could transfer the video files to a ramdisk before playing them.

OK, but I thought Class 4 cards were coming through at 15 and 40. So, I'm wondering if the I/O of the Mini can really handle the data flow of a Class 6 or not. If not, why waste the $$ on it, know what I mean? If it can handle it, then sure, I'll pop for the extra speed.

Class 6 makes a big difference in my Panasonic HDC-SD9 1080i HD camcorder. It's what I use.

I realize they are faster in hardware that supports them - I'm still looking for an answer from someone who has a Mini9 and has tested both types.............

I'm asking this mainly because I've had issues in the past with a Compaq laptop. At the time it came with USB 1.1 on it, and that turned out to limit all other I/O ports in the laptop to USB 1.1 speeds - even a USB 2.0 card in the cardbus slot. I ended up selling it. Don't want to make the same kind of mistake here.

tomshardware has a pretty extensive sdhc review. results are pretty interesting.

I don't think anyone (but myself) understands the original question (which I too am interested in the answer):

When using a Dell Mini 9, has anyone noticed a difference between read speeds of SD-HC Class 4 vs. Class 6??

Once again, we all know that certain devices (especially HD digital camcorders) will operate differently with a Class 4 vs. Class 6....but is there a difference when used on the Mini 9??????

I'll let you know after April 2nd.

I took a close look at both of my 4 gig SD cards (one for my camera, one for my video recorder). One is an OCZ that is Class 6, the other is a Sandisk Class 4. I'll copy some (identical) large and small files and also run a speed teest on them to see if there is a noticeable difference and let you know what happens.

BTW, the link to the TomsHarware review is EXACTLY why I am asking this. In the review, the card reader (not the card itself) was the limitation. I'm wondering if the Mini9 has the same type of limitation. Just 'cause I'm an alien and that's how I roll...... :geek:

I checked our digital camera and it had a class 6 SDHC from Kingston.

These are the stats I got from ATTO using the stock XP Home SSD.
