Hello,
since I've installed the last HTC ROM, I have a big problem : all my I/O accesses to the SDHC card are very very slow...
If I copy a file from my PC to the SDHC card, the speed is fine.
But if, for exemple, I launch a CAB file on the SDHC card, the installation of the CAB file is very very slow.
Does anyone else have this problem ?
I have the opposite.... when I'm copying a file from my PC to my phone (for example 2gigs of movies) it takes nearly an hour. When the card is connected directly to my PC it takes about 5-10mins... I don't have any problems on the device as far as I can tell...
I have same kind of problems. When I put my SDHC away, everything works fine. My SDHC is a 4 Go and it worked OK before I updated. Now, it happend that my device slows down or freeze during long seconds. What is going on ?

That's because the Titan is USB 1.1 so you need to insert the card into the PC directly for optimal data transfer rates.
No issue with copying to my 8gb SDHC. From the PC I am connected to a USB 2.0 hub. Launching Cabs from the card works just fine as well.
I have no ISSUE!!!

I agree the fastest option is to transfer large files using the USB 2.0 Hi speed card reader (assuming one came with the card). The TyTN II is a USB 2.0 Full Speed device which doesn't offer the same performance as USB 2.0 Hi speed but thats not the reason for the especially slow performance. There are several threads about this issue including here:
http://forum.xda-developers.com/showthread.php?t=350347
and here: http://forum.xda-developers.com/showthread.php?t=354629
I've just upgraded my TyTN IIs firmware using HTC eClub (upgrading my sig here next) and transfers using Activesync seem just as slow as they've always been. Perhaps next Microsoft can upgrade Activesync/WMDC to reduce that bottleneck. They really must try harder WRT Activesync IMO.

I have exactly the same issue : my device freezes all the time, for about 10-20 seconds, and sometimes it does also slow down....
I should make a new specific post for that.
I think it can be linked with the RADIO rom... But i am not sure... My provider is ORANGE France... Does it have something to do ?
My provider is also Orange France.
But I've found out what the problem was : Quick Menu.
Since I removed it, the Kaiser does not freeze anymore. I talk about that in another specific thread.
how is it possible that copying files to sd card over wifi or usb is much more slower than copying to memory of phone. and how to fix it?
because wifi transfer speeds aren't speedy at all since it's very similar to direct downloading off 3g/hsdpa and usb transfers through activesync is nothing compared to the blazing speeds of copying files from a card reader
i know that card reaader is fast but i asked why is coping files to main memory faster than copying to sd card over wifi. because when i download to mainmemory the speed is 250kB and when i download to sd card the speed is 30kB.i want to know why is it so?thx
I noticed this today when trying to send some large files to my SD card. Almost made me feel like the phone is not USB 2. It was going to take several hours but once I yanked the memory card out and put it in my pc it only took a couple of minutes. Good question.

This seems like WM5Storage with a UI make over. Looks like its for Windows Mobile 2003 2005 and 2006... probably a typo on 2005 and 2006. Anyone have them both and can compare speeds?
WM5Storage looks a bit lighter, cab is less than 50 kb... I have the cab attached if you want to check it out! It was working on my last flash (Duttys Hybrid WM 6.1), i haven't installed it yet on this one.
Slow for me too
I thought I was having a real slow copy this morning using USB cable to copy to micro-sd in phone. For camparison, I was copying a little under 4gb of music files to the 8gb micro-sd card and it took like 2 hrs. I would have popped it into the memory card reader on the PC, but for some reason either the reader or the PC (vista 64bit) does not like the 8gb SDHC card.
Mine copys pretty fast if you install du meter I think it will show you the transfer speeds. Maybe you have a generic MicroSD ?

For me, I'm using SanDisk. Do you happen to be using a SDHC card? I never noticed this speed issue copying to a regular 2gb card. Of course, it could be that I am copying 2-3 times more data now and just didn't pay close enough attention in the past.
cardreader works only after flash a new rom a thats all. and wm5torage doesnþt work at all

This could be because when you download something the device will write little bits of data every time a few kBs are downloaded, so many little writes. Memory cards are VERY slow at writing small blocks.
Downloading to phone memory and then moving to the card with an explorer might be worth a try.
Same problem with many little files, memory cards don't like those.
BTW, the speed of the Kaiser's USB port IS USB1.1-like. Maybe the hardware is USB2-compliant, but as all traffic has to go through the CPU the effective speed isn't any higher. It will take a good 20 mins to copy a 950MB file.
I have a tiny keyring microSD reader that's lightning fast. I have a 2GB card inside that I can use like a common USB disk, and when I need more space or want to transfer stuff to the phone I remove it and put the phone's 8GB card instead.

Hotfix for Windows XP that adds support for SDHC cards that have a capacity of more than 4 GB
http://support.microsoft.com/kb/934428
Not sure that'll work directly for you in Vista 64, but you might find related items. I had to do that to my laptop to get my Tilt's card to read in my work laptop which is running XP 32. I need to get a new card reader at home unfortunately, no matter what I do to it, it won't read SDHC.
Hello all,
I am trying to copy files from my computer to my storage card. I'm currently using WM5Storage. Everytime I try to move the files over, it indicates that my storage card is not formatted, and asks if I wish to format it. I always click NO because I have several cab files on the storage card that I can use in case something happens and I need to reinstall something.
When I try to move things via Windows Explorer (the mobile device folder), I get the same result.
Anyone know how I can accomplish this?
Thanks so much.
when connecting the kaiser to the computer (xp sp3), you can see a new network connexion created and opened at 10 Mbts. That means the usb link is usb 1.1, a poor performance for a material as the kaiser.
Big files, using usb 1.1 are very long to transfer.
Best regards

The Kaiser provides USB 2.0 'Full Speed' specs which means up to 12 Mb (as opposed to USB 2.0 Hi Speed which goes up to 480 Mb) BUT it's not the hardware that accounts for the poor file transfer speed, it's Activesync/WMDC. Anyone who has ever seen files transferring across to from a PC with a healthy (but old) 10 Mb NIC will realise the Kaiser via Activesync offers nowhere near that level of performance.
Anyone else experiencing excruciatingly slow USB file copying on Froyo? I've got a Class 6 16GB SD card in my phone and it's copying big files from my Macbook Pro at about 0.5MB/s.
It's driving me up the f***** wall, with a 1.2GB file predicted to take 27 minutes to copy across. Have I done something stupid to either my Mac or the phone? There's never been a problem in the past, but this is the first time I've tried copying with Froyo.
* Tried restarting phone and Macbook
* Turned off USB debugging on phone
Cheers,
Dave.
I've got a class 6 8gb card and transferring files from windows 7 goes at about 500 kb/s to 1mb/s. Extremely annoying.. Running froyo FRF83
Got a class 6 and it's going about 2.2 MB/s, I'd like to see it go faster too.
Hi ,
I have exactly the same issue , everything was fine with 2.1 ...
Need to test with CM6.0 when out maybe ?
No issue here moved 600MB in a few minute
same problem....
No clue why...but it limits speeds o ridiculously slow rates.
Get a card reader. Much faster even when you include the time to take out battery and remove/insert card.
same problem.
TEST using NexusOne with Cyanogen 5.0.8 (eclair 2.1): (stock SD card)
file size : 194 MB
time : 2 minutes 15 seconds (= 135 seconds)
194/135 = 1,44 MB/s
TEST using Nokia N97: (same SD card used before)
file size : 194 MB
time : 1 minute 08 seconds (= 68 seconds)
194/68 = 2,85 MB/s
Any news about this ?
Nexus One transfer speed smells like USB 1.1....
double post, sorry.

this is inacceptable!!! do i have to turn off the phone each time? is it a joke?
on my old and stupid nokia 5800 the transfer rate was triple or more....
The thing is, it used to be quick.

Uh, before 2.2 it used to transfer files about twice the speed it does now. I thought that seemed pretty obvious from "it used to be quick".
Just done a test using the same MicroSD card.
Hero (1.5): 5MB/s
Nexus One (2.2): 1.5MB/s.
I was syncing music via media monkey and it took AAAAAAGES so I assumed it was just the program. it's possibly due to how ur computer identifies it
anyone with froyo final? was been fixed?
I have had problems with my Touch PRO with the stock rom running SPB Mobile Shell 3.5.3(and earlier versions). 16gb class 6 card. After reformatting the card I can transfer some files to it fairly quickly, but after a while when i try to transfer files to it they will drop to insainly slow speeds like 16kb/sec.
I'm having this problem with the final release (FRF91) on my N1. USB transfer speeds are super slow 1MB/s. I think on Android 2.1, it was at least 5 times faster. When I transfer files now from my computer, it seems to transfer in bunches and then pause for several seconds. I have a 16GB class 6 card. Did anyone figure out a cause/solution to this?
*Bump*
I have the exact same issue with Froyo (FRF91). Before, on 2.1, I got transfer-speeds (write to sd) of 5+ Mb/s on my sandisk 16 gb class2, now it seemes to somehow be "capped" to the class2-speed of ~2 Mb/s (write). Not many post about this "problem" though, are there only a certain amount of phones that has this problem, or maybe every one else is using faster sd-cards, hehe

Yeah, it is pretty bad. Transfers over the USB cable are capped at something like 2MB/s or something similar to that I believe though don't quote me on it.
I believe it is the hardware and not a software issue.
when I copy big files, let's say, a file more than 10 mb in size, the average transfer rate is 1.5mb/s
otherwise depends on size of file, if the file is very small, few kb, then the transfer rate is unacceptably slow, 300kb or 400kb/s or even worse.
also I found, if I use SD card reader, the transfer speed can be doubled.
My SGS was bought back in September. A new one (feb '11) was in my hands a few days before and I saw constant write speed of around 9 MB/s on internal SD. Mine usually does 6-7 MB/s. Are new ones faster?
No cache involved: big files and overall speed
Same 6-7 MB/s.
I think is a very normal speed.
Can anybody with a new one (January or newer) test it?
Connect as a Card Reader and transfer big files (500 MB should be fine)
If using Windows, wait for the transfer to complete in order to see the real speed
not a valid comparison.. empty file systems have higher speeds you need to have the same amount of crap on there.. even that may not do it depending on fragmentation.. really need to start empty on both and do tests.
Hi, I experience something that I consider a very strange problem.
I recently bought a Mi 9 and discovered that its USB-typeC is only USB 2.0. This is rather disappointing, but USB 2.0 should still give 480 mbit/s = 60 MB/s transfer speed.
However, the real USB file transfer speed from PC to the phone is only 27 MB/s.
I've tried everything - MTP/PTP, adb, running FTP server on the phone through "usb modem" network.
I even setup Linux hostapd on my laptop which has 802.11ac with an Atheros chip, connected the phone to that network and got 780 mbit/s theoretical speed.
Then I started an FTP server and retested: still 27 (maybe 28-29) MB/s to the phone. At the same time, it reached the speed of 65 MB/s (=520 mbit/s) when copying a file FROM the phone to the PC.
Then I even launched Terminal emulator and started a download from the PC to the phone with `curl`. And guess what, I still got 27-30 MB/s. Even when it's downloading the file to /dev/null instead of the phone's flash memory - it still gives 27-30 MB/s.
Then I launched THREE curl's at the same time. Three of them gave me 30+30+20 MB/s = 80 MB/s = 640 mbit/s which means that my 802.11ac worked correctly.
So my question is: what is that fixed limit of 30 MB/s per process?
And what file transfer speeds do you get with your Mi9's?

im not so technical with specs of write/read speeds but, at least i can say the same, mine to transfer around 6GB takes about 30 to 40 minuts so, i guess is around 25 to 30 mb/s, USB 2.0 on a phone this good is the only downside to have a phone without microSD slot to compensate the slow USB 2.0 speed, or worse than that.

It's worse. 6000MB/(30*60) = 3 MB/s...
With 27MB/s it should take ~4 minutes to copy a 6 GB file...
And it should be even more, most usb 2.0 sata enclosures max out at 50-60 MB/s...

and i am talking about 6GB of more than 1300 pictures with ~3 to 5mb each so, probably will take more cause is not a single file.
i dont know wich method you use but i connect my phone and select MTP not PTP.
evenm its so damn slow, i regret the speed i can go with my G6 wich have usb 3.1 and thats was amazing quickly compared to Mi9.
i dont know why Xiaomi dont implement usb 3.1 on their high end models, they can make it, and even if we need to pay 10 to 20 bucks more is way way better than waste a lot of time copying files into it. - since they didnt provide microSD eighter.
My redmi note 9 also slow transfer speed but it solved now, on PC I compress all the files, transfer compressed file to the phone the extract it on the phone.

That is the THEORETICAL MAXIMUM that USB 2.0 can achieve. In practice, NO USB 2.0 drives, I repeat, NO USB 2.0 drives ever reach that speed. The fastest one reaches only 42MBps sequential write speed and is an externally powered hard drive, while the fastest flash drive only reaches 25MBps sequential write speed (data taken from usb.userbenchmark.com, so it's sourced from multiple real world users instead of a controlled lab environment). Your 27MBps then is already a good one.
