1) I have not tried any non-Sandisk Ultra II models of SDHC cards greater than 4GB.
2) I have not noticed the speed of slower cards affecting its usability with V-Mate (the speed DOES affect how quickly I can transfer data to/from an (XP) computer and the card (using Sandisk Micromate card reader) and I find the Ultra II good in that regard (and "faster" Sandisk SDHC cards would not transfer data any faster than the Ultra II for my setup)).
3) I have found sales of Sandisk Ultra II every now and then (when I keep looking) in the $3 to $5 per GB range ($50 for the Sandisk Ultra II 16GB at a local Best Buy store, for example). If you have a fast V-Mate to PC connection, I recommend off-loading files to a hard disk.

I dont know whats the problem with your sdhc card, but I'm using a Sandisk Ultra II SDHC 32GB and it works great. Be sure to update to the latest firmware.

At risk of repeating myself, have you recorded 32Gb of video in one session?
As I wrote previously..
I hope your right, but I suspect you haven't fully tested the 8Gb card, with mine it seems to have a 4Gb limit, any video recorded under that size will be OK, but if you record over 4Gb the V-Mate will freeze, and even though a video is stored it is actually unviewable. (I tend to record my security camera at 320x240 at 25fps which gives just over 1Gb per hour, so that's four hours recording.)

One last comment: it is a shame that the V-Mate programmers were not able to (successfully?) code a graceful exit to the filesize overflow problem by closing the near 4GB video as though the user had pressed the STOP button just before the overflow would have occurred. As it stands, the V-Mate just crashes, needing to be manually powered off in the back and leaving the memory card with a large "orphaned" string of 32KB clusters which have to be manually deleted (in XP:Right Click on Drive Letter/Properties/Tools/Error-checking/Check Now/Automatically fix file system errors/Start). It may be that they did not have a memory card large enough to test their code. This would be a really nice bug-fix to have in a future firmware version. I'm sure it would benefit SanDisk by resulting in increased sales of the 8, 16, and 32GB cards. (Thanks for your thoughtful consideration, SanDisk!)

Great to hear that the SanDisk 32GB Ultra II cards work with the V-Mate!
Will you make a similar post when you test out SanDisk's first 64GB SDXC card (reformatted for FAT32, as I presume will be necessary)?

You guys are right, my scheduled recording of 2.5 hrs daily "hanged" on the 8th day, maybe its when the 4Gb limit was reached. Might as well replace my 32 with a 4. thank you guys for the info.
