Slow miniSD, normal? - 8125, K-JAM, P4300, MDA Vario General

I was considering buying a better miniSD card cause of slllooww transfers to and from the PC, like music and such.
When I enable WM5 Storage, I can run an HDtach benchmark on my PC to see just how fast it is.
I got 0.8 MB/s @ 7ms, which sounds about accurate.
When I plug the card straight into PC, I get 7.5 MB/s @ 1.5ms.
Does everyone get this?
This is with a Cingular 8125, with Faria's AKU 3.3 ROM. Though it's about the same with the stock ROM.

Try this:
Modify the following two reg keys to increase the transfer speed of your memory cards
hklm\drivers\sdcard\clientdrivers\class\mmc_class
hklm\drivers\sdcard\clientdrivers\class\SDMemory_class
And change value of BlockTransferSize from 64 to 128 or 256.
Hope this helps!

Thanks, tried that out. I'm thinking that doesn't help with PC-PPC interface though , just PPC-MiniSD interface.
The fact that 8125 uses a USB 1.1 interface doesn't help any. That only allows for like 1.5 MB/s (12 mbps).

Q-TEC 9000 with Transcend 4GB SD slow transfer

Can anybody tell me how I can fix my transfer speed with ActifSync 4.0.
Because if I upload the transfer rate is about 100 kb/s.
Anyone with the same phone and sd-card please help me.
Thanks

If you want faster transfer speeds use a card reader. Using activesync the data first gets moved to the universal, then from the universal to the memory card. This is very slow due to the limited bus speed of the universal.
But with my 512 mb card, I get normal speed. I think you dont understand how slow it is. Let me explane.
512 mb > 3 sec 1 song
4 gb > 30 sec 1 song
Yesterday I bought a Transcend 4GB 150x SD card.
It's very slow; not only when using it in my HTC Universal, but also in the cardreader in my PC.
I'm going to return it tomorrow...
Jan after reading some reviews they say that it is one of the fastest cards. I think the problem is with the reader. I can now transfer at usb 1.0 speed with Card Export II.
Are there any app. with 2.0 support?

Very slow writing speed on microSDHC card

Happy new year guys. I bought two microsd cards. One is a PQI 2GB microSD card for flashing. Another one is a Ridata 4GB microSDHC card for everyday stuff, with a speed class of 6. I don't know the class of the PQI.
I noticed that when copying files from the pc, or when just copy pasting files within the Hermes, the writing speed is very slow. For both cards, the PQI and Ritek, they're around 400 kB/s to 600 kB/s. I used both WM5torage and activesync and they're both this slow. Even for a class 2 card, such speeds are slow. I RMAed the PQI one due to CRC errors when copying. The Ridata has no errors but is still very slow.
I searched the forums and installed the SD tuneup.cab file, restarted the Hermes and its still the same writing speed, around 400kB/s. I used the microsdhc in a card reader in a pc and it writes at 6 MB/s. What could be wrong, why such a writing speed difference? I have red about posters with writing speeds as much as 9MB/s with their phones in the Hermes accessories forum.
The specs of my phone are:
Cingular 8525 Hermes 100
PDACornerPro.V27
Radio 1.56
HardSPL v7
Ridata 4GB microsdhc class 6
Any suggestions, comments? Thanks.
Mate, join the club... I don't really believe that when connected through activesync you will get very fast speed copying. Its ALWAYS been slow as a stoned snail when copying through the phone. sd card readers move like lightening in comparison.
Don't believe you're gonna find an answer to the slow speed problem.
Cheers...
You mean from the very start till now, the Hermes really writes slowly? But some people on the Hermes accessories forum have write speeds up to 9MB/s. Maybe there is a fix/tweak somewhere I don't know about and still not able to find through searching? Any ideas? Thanks.
I've never found it. Most threads I've read about this issue are lamenting the fact it has such a slow read/write speed when connected through activesync.
I generally backup and transfer files through an sd card reader.
Cheers...
Thanks for the reply. Maybe I'll just use a card reader to save time. But those folks at "What brand SDHC card is everyone using?" thread have speeds up to 9MB/s when writing. Aren't they using the Hermes? Or they're using a card reader?
Probably a card reader. They may also be talking about when transfering files to/from sd card when using the Hermes's own file manager as that is fairly fast. I use a class 6 8Gb card for reading Tomtom maps and there is no lag, had a bit previously with a 2Gb card.
I believe the hangup is in microsoft's active sync program. No0t sure about those using vista's own transfer app.
Cheers...

Actually, Activesync can be fast.
Activesync on an XP machine copying to my Herm100 is quite slow, a card reader is much better, but the same Activesync copied to the latest HTC (don't know the model) slidey keyboard phone's internal memory in comparatively lightening speed.
So is there different configurations or drivers for the USB connections on our phones and/or ROMS ?

As you said

Maybe something in the hardware of the newer phones because if it was software, since the chefs use the ported os of the later devices, we should also be getting better speeds if we had updated the OS. I'm currently using build 21109 and I haven't noticed a speed increases...
Thanks for the replies guys. I think its really the hardware of the Hermes that is slow. I bought a cheap $1 card reader and its very fast compared to the Hermes' own card reader. I used Sisoftware sandra to bench my cards. My RMAed 2GB PQI card writes at around 6.5 MB/s while my Ridata 4GB card writes at around 5.4 MB/s. What a difference a dollar makes

Why is USB transfer rate so slow?

Hi experts I was hoping somebody here could throw some clues my way.
I have a 32A Rogers magic. (rogers HOFO )
I usb mounted the drive, and transferred a movie on there just for fun, and it was really SLOOOOOW , using the 2 gig sandisk microsd card it came with
So I tested the transfer rate, and write was about 3 meg/second. ouch
reads are about 5 meg/second (!)
SO I got an 8 gig type 6 card to solve this problem. I tested it first with a usb card reader, it reads at 16 - 17 meg/second (same usb port)
Put it in the Magic, and I'm back to 3 / 5 again, with the new card too.
The specs say "USB 2.0" - yet this is unbelievably crappy usb transfer rates :-(
I tried my buddy's Dream, it's exactly the same too. 3 / 5
Why? Any clues? Is there something to tweak?
are you using the usb cable that came with it or your own one?
either way, have you tried a different cable?
yes, tried that. And with a whole other phone, computer, and cable ;-)
I just tried it again though, it's the exact same, 3 MB/s write, 5.7 MB/s read on the HTC cable, and the normal one I use.
Why, is yours faster?
Could you use a stopwatch (like www.online-stopwatch.com),
and copy around a 100 or 150 meg .ZIP file to it, and tell me how many seconds it took?
i just transferred a 550mb video clip from my laptop to my phone and it took 1m 28s.
my laptop isn't particularly fast either, so will have had some affect.
Thanks
That's about 6MB/s (550/88), that's better for writes than mine, close to double...
How long does it take to get it back, reading?
59 seconds.
but don't forget my laptop sucks so that time will be a bit high.
9.3 MB/sec still kicks mine. Thanks for checking that out.
This one reads really fast on a card reader, over 16MB/s
I guess it doesn't like Android phones. :-( I don't get it.
What brand / class is your card? Mine's transcend 8GB type 6
mine is the same.
at least, i think it's transcend.
it's certainly 8gb class 6 anyway.
just a thought...
what rom are you using?
the default or a modified one?
The HOFO roms
I've got it up to 8 to 9 MB/s writes, and 6- 7 MB/s reads now
That's exact opposite to yours, lol.

USB Sync Speed

Hi.
There's one question which has not been asked yet (I think) and that's about USB Speed.
When I connect my HTC Touch Cruise to the PC and start a file transfer I get speeds around 250kb/s. What about the new Leo? Is there any improvement?
when syncing mp3s with wmp I get around 2-3MB/s but I haven't tried large files yet. using the included 2gb card of course!
With an A-Data MicroSDHC 8GB class 6, transferring a 680MB file I'm at full speed.
I mean that I'm getting 5-6MB/s!
The transfer speed of the HD2 is a joke when compared to the USB 2.0 specs and the extremely low transfer speeds does not have anything to do with the cards used.
There is a big difference in the speed of ANY card when used with hd2 compared to a card reader. And the truly limiting factor is only the hd2.
When i'm in "disk drive" (not activesync) mode the write transfer speed to the sd card is only about 1.8 MB/s which i think extremely slow. The read speed is only ~3.5 MB/s.
I've tried that with 2 different cards, both 2 GB sandisk.
When i plug them into my PC or notebook using an USB-adapter i have the write speed ~5.5 - 6 MB/s and read is ~ 8-9 MB/s.

So the speed is about 3x higher in any card reader.
Take alook at the following thread:

Don't forget this is going through activesync, which is a protocol that really isn't meant for large file transfers. And that previous phones were only doing a couple hundred kB/s.
Use Disk drive mode when transferring big files. Hits 5MB/s.
@kilrah:
please read my posting above:

OK then, but in that case you're off-topic as the thread was about activesync
Anyway, I can't duplicate that. In disk drive mode I have 4.5MB/s writes and 6.5MB/s reads, similar to what someone else mentioned earlier. With a 8GB class 6 Sandisk card.

Yup, same here; I got fast speeds when not in Activesync and applied tweaks to my Win 7.
It is also notable that unless tweaked, Win Vista and Win 7 copy files poorly (even between 2 different physical hard drives!) so compounded with Activesync, Windows may be contributory factor to the OP's problem.

micro sd transfer slow.

can anyone let me know if the rom used in the hd effect the speed of the transfer of files when the hd is connected to the pc as mass storage
since i got my replacement phone a few weeks back the sd transfer speed has been sketchy. im getting speeds of 32 kbs and im wondering what the cause is
windows 7 rc
the phone (hardware)
the phone (software)
the cable (my htc cable split so im using others)
the card (sandisk 16gb class 2)
so ive ruled out windows 7 rc as the slow transfer speed in consistant with xp pro home and a retail windows 7
at first i did think is was the cable but ive used a good few to try and see if this is the problem. the pattern of slow transfers run throughout the wires i have
i have tried another card in my phone and i got the same result
this leaves me with two possibilites
the phone hardware (oh and it hs newton rings) is screwed and i need a replacement
or
the phones rom is conflicting with the transfer somehow
can anyone tell me if theyve experienced drastic changes in the transfer speed depending on the rom used
Hi
Since i had a replacement from Orange a few weeks ago everything has been - well faster and without problems - and that is with the stock Rom. Loaded all my old apps and have no complaints. Will measure my transfer speed and let you know.

I've noticed transfer speed from SD to PC has become very slow, but this appears to coincide with some of the latest rom builds or possibly wm6.5.x. If you revert back to a stock rom the transfer speed is back to normal
Well SK Tools tells me the write / read to my Sandisk 16gig card is
Write 803.66 KB/sec
Read 6880.18 KB/sec
With data transfer via the cable to my laptop I used CrystalDiskMark to measure and the results were

To confirm I copied a 150MB film from the HD to to PC and it took 24 seconds.
I don't know if any of this helps but as said before I am happy with the speed.

Micro SD HC 16GB Slow trnasfer speed
This is as confusing as it can get...
i can transfer 10MB under 2-3 seconds... but as soon as i go to transfer a 400MB video file i recored on my Samsung Epic in 720HD mode.. it wants to transfer at like 200KB/Sec.. like what's that about.... so i shoot a quick video... with file size of about 5MB.. and it transfered faster than i could blink.... Are these cards like some how restricted to make our larger file transfers a miserable hell to back up to the computer???
Any help wold be appricaited...
My system specs..
Windows Vista ultimate 64bit
Quad core 3.4Ghz ( That can't be an issues lol)
A gigabit mother board with USB 2.0 and 3.0 ( same results from both)
6GB DDR3 Ram
etc.....
Thax...
its the cable you are using
i tried using other cables to connect my hd to the computer and it is slow
and when i tried with the orignail it was faster
so i think you might need to buy a touch hd usb cable
