For the geeks

What's the difference between a Multimedia Card (MMC) and a San Disk
memory card?

My DV recorder came with a MMC card for still images, but its only a
measly 16MB, so I want to buy a larger card. My digital camera takes SD
cards that work in the DV camera, but the MMC won't work in the digital
camera. So I think I'd like to buy a couple of 1GB SD cards that can be
interchanged with the two cameras. Is there any reason I should not
use a SD card instead of a MMC in the DV camera?

From:

"Secure Digital & MultiMedia Cards
By physical dimensions these are the smallest of the memory cards and are
therefore commonly used in ultra-compact products. The only difference
between Secure Digital cards and MultiMedia Cards is that Secure Digital
cards have a write-protect switch for added data security."

Thanks, Dan-san. I wonder when that article was written, as the next
line is a doozy: "Currently 512 MB is the maximum capacity for these
cards though larger capacities will be out soon."

An article written just a year ago in PC world
http://tinyurl.com/yqe7w said that they expected 1GB cards later that
month (Jan, 2005), while the SanDisk website currently has them up to
2GB today http://tinyurl.com/78v3k.

I'd say SanDisk is ahead of the curve of Moore's Law.

I've no idea when it was written, but I agree -- seems a bit dated. I have a
1gig SD in my brand-spankin' new Optio, so...

I just googled "media card differences" (no quotes). Found a bunch of sites
that said essentially the same thing.

I'd guess that any company wanting to be successful in selling doo-dad
electronica would have to be.


I wonder if Moore and GM worked together on the whole planned obsolescence
thing?

Moore's Law refers to the rate of increase of the number of transistors
per chip (roughly proportional to computing power and inversely
proportional to cost of computation). It doesn't apply to the rate of
increase of capacity of various storage media.

BTW, SanDisk (SNDK) has been a spectacularly performing stock over the
past six months.

Moores law is processing power, not storage, so SanDisk is not doing
anything illegal.
By the way, I use SD cards. They fit in my Palm Pilot, my camera and
my thumb drive. I have a couple of 512 meg cards that I switch from
device to device. I can take a picture, pull the card and put it in my
Palm, look at the pic on a larger screen (even use a Palm application
to edit it or the picture data), pull the card and stick it in the
thumb drive, then download the pic to the computer. Works grea.

Ahhh, correct. Its Kryder's Law.

Kryder's Law applies to hard drives, not flash memory.

Looks like an opening for Buck's Law, Myron. Better jump on it.

The most efficient way to get correct information on the Internet is to
assert confidently the answer you believe to be right (or at least that
you *apparently* believe to be right). All it requires is a willingness
to look bad on occasion.
