Holy Ludicrous speed batman! (SD Card Benchmarks/Speed increases!)

Please post all questions and replies to sonny486's thread. All the info is there and I won't be replying here. This new thread was made to get this issue a bit more exposure since the speed increases are notable and we could possibly all benefit from them.

-----------------------------------------------------------------------

I have run some SD Card benchmark results of various PDA units running WM5. This was prompted after upgrading my SD Card to a SanDisk Ultra II, and then tested more after modifying my registry to resemble the Treo 700W. I ran all the benchmarks 3 times however decided not to average because the results did not have much variance.

I started tinkering with the SD Card registry settings after reading the thread started by sonny486 here.

I began to contribute to that thread at post #86 and the registry settings I am using at the time of this writing (11/17/06) can be found here.

2.0GB SanDisk MiniSD Ultra II (After modifying registry)
Write 701.61 KB/sec (Nearly 100% speed increase)
Read 657.12 KB/sec (Roughly 33% speed increase)

After getting the much improved results above I ran the benchmark on the following devices with no registry modifications to establish some reference points.

Verizon VX6700
2.0GB SanDisk MiniSD Ultra II
Write 336.92 KB/sec
Read 485.42 KB/sec

Verizon Treo 700W
2.0GB SanDisk MiniSD Ultra II
Write 564.65 KB/sec
Read 1196.03 KB/sec

Tmobile MDA
2.0GB SanDisk MiniSD Ultra II
Write 223.00 KB/sec
Read 786.89 KB/sec

The VX6700/PPC6700 clearly have inferior registry settings. After modeling my settings to reflect those of the Treo 700W I gained a 100% write speed increase and roughly a 33% read speed increase.

I was amazed by the Treo's Read speed; clearly the device has superior hardware inside of it.

I plan on further benchmarks/registry modifications to try and find the best combination. I will let you guys know what I find.

Good luck.
