Panasonic Boosts SD Card Speed
"Matsu****a Electric Industrial, better known by its Panasonic brand name, will begin selling a new series of SD (Secure Digital) memory cards internationally at the end of October. The cards will offer double the data transfer speed of its current fastest cards, the company says. The cards, which have capacities of 512MB and 1GB, are the first two members of its new Pro High Speed Series and are able to transfer data at a maximum rate of 20 MB per second. The previous-fastest SD memory cards made by Panasonic, the Super High Speed Series, transfer data at speeds up to 10 MBps, according to Karl Takahashi, a Panasonic spokesperson."
More speed? Delicious - especially as the card capacities increase and it takes longer and longer to fill them up with content.

SPEED.
Never thought I needed it until I started "reading" audio books.
Always thought the damnable Audible reader took forever to load an 80mb book... but I'm thinking it's prolly the plain vanilla Sandisk 128mb card.
Hoping, anyway.
Prices?

Good news, but do Pocket PCs benefit from the increased speed at all?

Does anyone have a link to a chart comparing these SD, CF (flash), CF (microdrive) and standard IDE hard drive speeds? I'm curious.

Yes, but there is obviously an upper limit to do with the internal transfer capability. I'm not sure exactly where it is at the moment.
Still bigger, faster, better. Cant' beat it. :mrgreen:

any card over 3mb/s is a waste.

Hmmm, where are you getting those figures from Nuka_t? Sounds too low to me. Don't forget the speed of transferring data onto the SD card via USB2 or firewire readers. The faster, the better.

Well, in the world of digital camera, speed is everything.
Imagine taking a singleshot raw image with an average size of 8 megabytes each. On a high end digital SLRs (such as Canon 1D, Sigma SD10, etc.), this is a simple comparison of write duration :
- Sandisk Ultra II CF card (6.5 MB/s)will take at least 3.1 seconds.
- 40x Lexar Pro will take at least 2.1 seconds.
- On these newer Panasonic 20 MB/s, it will only take less than a second.
Now, things are significantly more interesting when you are talking about continuous drive mode, where a camera can take up to 8.33 frames per second, to a maximum of 20 frames in 8megapixels mode, which is comparable to 180 megabytes data taken until buffer is full, would you rather spend 60 seconds (on sandisk ultra II) or 20 seconds (on panasonic 20MB/s) to flush the 20 raw images out of your internal camera's memory ?

thats the max speed you can get on an axim. on a digicam or usb reader, more speed is useful. but this isnt "digital camera thoughts".

I'm honestly wondering the same thing? I also saw the announcements from DPReview about these new twice-faster 20MB/sec cards from Panasonic Pro High Speed and SanDisk Extreme III coming in October, but the press releases seemed to mention that the cards would just work at the previous speeds (<=10MB/sec) in existing high-speed devices? What does that mean? Do new devices need a slot interface with wider bus or something (like say 8-bit)?
Besides Pocket PCs, I'd also like to pose this question in regards to pocket digicams. For example I was about to buy the Kyocera Finecam SL400R that requires at least 10MB/sec SD card to do its 4MP 4fps continuous shot mode. But would a 20MB/sec SD card just be wasted in terms of the actual utilized transfer rate required by this camera?
I was also about to buy that Kingmax 10MB/sec 1GB SD card from NewEgg (currently $89), but maybe I should wait? The announced SanDisk Extreme III 20MB/sec 1GB SD card has an MSRP of $140 so the street price might actually be close to the 10MB/sec cards?
P.S. Incidentally for the digicam I also can't decide between the Kyocera SL400R or the newly announced Contax U4R (and Contax i4R), also to be available in October supposedly...
