Hi!

I was looking for a good 2GB SD Card for my iPAQ hx4700.
After some research I decided RIDATA 2GB PRO 150x should be ok.

While copying large file in desktop Card Reader it shows 5mb/s constant transfer rate.

But... Card Benchmark in Pocket Mechanic shows:

Read: 0.14 MB/s (1.1x)
Write: 0.05 MB/s (0.4x)
Fat32, sectors per cluster: 8, cluster size: 4096

I have tested several different file system options (fat16, fat32, cluster size etc.). Doesn't help much.

My question:
Should i try full (low level?) format of the SD card?
I've done only quick formats until now.
Is there a difference if I format it in my card reader or directly in iPAQ?

What could be the cause of this slow benchmark results?

Possible solutions ?

Thanks in advance.

The short answer is that the internal CF interface on PDAs are much, much slower than the USB 2.0 spec. Having said that, your benchmarks look really off to me as well. BTW, never do any disk maintenance (format, defrag) on the PPC, especially if you already have access to a card reader.
