kingmax 1 gb trouble

[Choirguy]

I invite all of you to join our quest to collect Data on 1 GB (and larger) SD and CF cards...

However, preliminary data by different users shows that Kingmax 1GB 60x cards have a read speed of 6.8x-7.4x in Axims (X30s and X50s) which is pretty much par for the course...

But write speeds are at 0.01x, whereas other cards typical write from 0.08x to 0.10x. THAT is significant, and is where your errors are coming from. Clearly, the Axim has a write speed much faster than 0.01x.

I'm still hoping for data from Sandisk users, Panasonic users, and others.

Right now AGP and Lexar have the best performance. Again, data is limited.

On a sidenote...How do faster SD cards work?

I mean for faster Hard Drives, it's a matter of higher RPM speeds and bigger file cache...But Secure Digital cards are solid state (no moving parts) so how is 1 card FASTER than another when there's nothing moving around?

SD cards have memory controllers with processing capability that run at different speeds.

about how long does it take to fill the 1GB up over USB2.0 ?

depends on card speed. my writes at 5MB/sec, roughly, so 3 mins 15 seconds. longer for multiple files.

And what's a small, solid, fast, yet cheap card reader ?

see link in my signature.

this god damn card must be pulled out and re-inserted at least twice a day. i have never been so unhappy with, what should be a good product, in my whole life.

I have still not found a replacement that runs at 64x, but i am considering just getting the Lexar 32x one.

how fast exactly does the 64X card write in the PC, in terms of MB/sec? (real-world experience)

theoretically it should write at 9.375MB/sec ("X" = 150KB/sec), which is basically the same advertised speed as a Sandisk Extreme II SD card. (9MB/sec minimum write speed.)

PS- I also encourage everybody to check out the thread Choirguy linked to in his post above.
