sdhc Kaiser II TeRrIbLy slow

[securedigital]

Hi everyone

That's my first post! I've been hanging around here withwout becomming user so long...till now.:)

I have just bought an sdhc card ( dont know the class ) and it's working EXTREMELY SLOWWWW on my Kaiser TyTN II (htc) when I mean slow, i mean below usb1.0

I'm using Card Export II, compatibility with Hermes devices, and when writing a single mp3 through, ~6mb it takes 5 minutes. Transfer rate is below usb 1, and that was weird, so i've checked to transfer ~6mb to anotrher microSD card (256mb old card from old phone, nokia brand) and the song was copied pretty fast, reaching usb 1.0. bitrate

Imagine to copy a 400~mb film on my new card, :eek::eek: even i can't copy mp3 ...to slow...ah, almost i forgot it, the new card, kingston sdHC with it's HC pc card reader works exellent, usb2.0.

How that can be possible? an old card is working at least 4fold times faster!!! than my new Kingston sdHC 4gb.


Any idea?
Really appreciate.

Any idea about that?
Someone is using a Kaiser II with Card Export II? having reeeaaaly slow data rate¿


thanks

As you know, the Kaiser only supports USB 1.1 and thus (s)low speeds.

First of all, disable the Hermes workaround option. Activating the option reduced my transfer speed by half (approx.).

For large files, just use an external USB 2.0 card reader.

In the past I have done a test to get an idea of the different transfer speeds:

Just wondering: which ROM are you using and which class has your SDHC card? (Me: -G-'s DK.10 series - WM6.1 & SDHC Class 4)

As to why your transfer rates are so low, I have no idea...

Hi!

Mhhh it could be the rom....i've even tried tweaking registry parameters (increase sd bloc size, etc) with no significant success on writing speed.

I've got and kingston 4gb sdhc class 4, rom WM6 prof compilation 18125.0.4.2

I had this problem with a Kingston 8GB Class 4. I tried tweaks and other roms, no luck. I ended up exchaning the card for another one that was exatly the same, and it completely solved my problem. I think a bad one gets in the batch from time to time. It took like 2 minutes to transfer 500kb. Granted, it takes a long time to transfer files anyways, but not that bad.

I've heard this from other people as well. However,

if not mistaken, i think i've read somewhere stating that kaiser max spped is usb1.1 and class2 for sdhc (hardware limitation)

well

I jave update the rom....to hyperdragon III and things got worse....
Now, can't even connect with pc via Card Export....and the worst of all, my gps got ruined.

More than 45minutes to catch gps signal:mad::mad::mad::mad:
Before flashing, with the original rom i got satellite inside home, now...now not even outside....

Gps is now spoiled.
I've used [13 January 2009] HyperDragon III Raphael OS 5.2.21009 Build 20931.1.5.0

Now i should fix the gps...any idea¿? reflashing the rom would be painful.


Thanks

The fastest transfer rate I have found was via a ftp server on the kaiser. Its called Mocha Ftp Server. Works via wifi :D


Hope this helps

P.S.

I dont think HDIII comes with a radio. Maybe you are using an incompatible one. Look at the list on his page and download a matching radio for WM6.1 ( as this 100% will cause issues with any radio function including GPS )

It's not only a hardware thing.. I am using an sdhc 8 gig from sandisk, and just reading/writing to it is slow (even w/ an external reader as oppossed to the one in my comp)....
I guess it's like trading off mileage for speed in a car though.............. I dunno, I'm about ready to chuck mine, good thing it only cost me 29 bucks.
