any difference between regular miniSD and Sandisk Ultra II miniSD card in the HV20? at DVinfo.net

Is there any difference between regular miniSD and
Sandisk Ultra II miniSD card in the HV20? I do realize
the Ultra II is obviously faster, but does it matter in the
HV20?

Thanks!

P.S. Why did Canon feel the need to go with miniSD
and not the regular-size SD cards? It doesn't really
save all that much space(and kind of pointless in a
camcorder) oh well....

I have a regular SanDisk (not ultra) miniSD card, and it seems to record fine, but it has a LONG startup time (browsing the card?) at card-mode startup before I can take a picture. (at least 15-30secs.)
Card tested at 4.5MB/s write, 25MB/s read (avg, higher peak) on my USB2 reader.

It's not such an issue w/ tape since this "browsing time" is taken up while you do videos.

I might recommend a faster card perhaps if you can afford it (often you can find rebate/sales deals.)

Hi!

Could you tell me how to test the speed of the memory cards? Thanks!

Also, I ordered the Sandisk Ultra II 2GB miniSD card
from Costco. Their price is $42.99 plus $7.79
shipping for a total of $50.78.... pretty decent price...

I figure I can put the miniSD card in its adapter
and use it as a regular Ultra II SD card... :)

For test speed, I just copied some large files to/from the card , using GP Software's DirectoryOpus file management tool, which includes a speed meter.
I could also use SiSoft sandra or other test utils but this was more convenient.

Actually I do have an UltraII sandisk SD card (for my still cam), it tested (on same tool) at 7+MB/s write (much faster), 8.5MB/s read.
I think the 25mb/s miniSD read above was an erroneous reading.
In any case it's prob more read speed important than write, for 2MP still pics... high-speed writes more important for high-MP still cameras and direct-write movie modes.

That's a good price for 2GB card... best price I've seen is around $20/gb.
BTW the test above was in the SD-card adapter, it works fine.
It will take you a longggg time to fill a 2GB card at 1920x1080 res (~1-2MB/pic), but what the hey :) good for still cams also.
