Slow SD Speed

I seem to have a slow SD card interface and wonder if this is a trait of the rx3115, or caused by something else.

I purchased an A-Data 60x 1GB SD card and have used up around 900 MB of it. The card was defragged, so all files were contiguous on it.

I ran Pocket Mechanic and was surprised to find my scores were the slowest ever recorded. The "read" speed is around 0.02-0.05 MB/sec. The strangest part of this, is the "write" speed is around 0.10 MB/sec. Both are slow, but the write speed is normally the slower of the two.

Is there something I should check or do? When I ran the tests, there were no other running programs. I also ran the tests with the SD card formatted and the results were the same.

I purchased the PDA a couple months ago, and have it registered with HP.

Thank you.
