View Full Version : Why is transfering files like avi's to my new Ipaq 2215 so slow?

Hello,

I just picked up my Ipaq 2215, and I love it! Now, I'm trying to figure out if my SD card is going bad or if my SD slot on the 2215 is bad. First, I had problems with my SD card when I tried installing some software to it, and my device shut down cause it was not charging. After I fired it back up again, I noticed all these weird characters in the root of SD card. I tried deleting it, and I kept getting error saying another program is using it. So I hard reset the 2215(I didn't have much stuff on it) and then tried deleting these files on the SD card, and still nothing. SO, I went out and bought a SD card reader, formated from my computer and everything looks fine now! I installed tons of programs on it and it works! But it just seems like it install things pretty slow(like LINKS, or Adobe READER) and when I tried copying a AVI file to it, it took forever! As appose to copying files to my SD card from the SD card reader!
WHich I don't understand cause they are both using USB to transfer files!
Anyone please explain?

Thanks!

Well, it'd be slower through the PPC than through the reader because it has to go through an OS layer rather than just looking like an additional drive to the PC. So basically you have the PPC receiving the data and sending it to the card rather than the data going to the card directly.

Not sure if that's the whole problem, but I wouldn't expect identical transfer rates even if everything is OK with the PPC.

The other question (and I don't remember the answer about the 2215), is which *version* of USB is it? 2.0 is much faster, and if the reader is 2.0, but the PPC cradle is an older one, that could also slow it down.

yeah, definitely none of these PPCs are USB 2.0. The card reader prolly is (maybe not) but it's definitely slower on the PPC because of write speeds. A dedicated anything can do the job better than something else that can do it also (along with many other things) So yes, the dedicated read/writter is gonna be tons faster even if both were USB 1.1

If you have usb 2.0 on your PC or laptop, get yourself an inexpensive multicard reader like the PNY "High Speed USB2.0 Reader" (reader/writer) and write the files directly to the SD card, if they don't require conversion.

For some files, you may want conversion, like PDF files so that they can be "marked" for easier reading on the pocket pc. (I'm using PPC2002, don't know about 2003).

Sounds as though this is the same old problem encountered when transfering large files onto the SD card in an Axim.

A card reader is the only way when dealing with these cards, a lot quicker as well.

Remember: ActiveSync will only run at serial speeds, regardless of whether or not you have a USB connection...

Sorry, but I have to completely disagree. I run IP Dashboard and it monitors the upload / download speed of all the connections on my Ipaq. While using a USB cable / Actice Sync I get around 1.9 Mb/s while downloading large files like movies. BlueTooth peeks at 800 Kb/s...
