slow copying to SD card

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.

Go for USB and Softick Card Export for Windows Mobile for file operations.

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.

Very slow USB transfer (Froyo FRF83)

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.

Copy music over to Captivate... Super Buggy & Slow? wtf?!

I copied some music over to my internal sd card last night and i was running GeoMod, and all of a sudden my captivate became super buggy and unresponsive. So i thought okay, something with geomod.. So this morning i did a fresh JF6 --> AXURA to try it out. Copied my music over...and.... still doing the same thing is there somewhere in specific i need to put the music files to avoid this? i have the mp3s in folders according to artist in a MUSIC folder on the internal SD. and its only like 1.5gb of stuff...
Any help would be nice
Thanks

I've never just copied and pasted. Use an app (I use doubletwist) to transfer and see if that works.....

Are you sure they are mp3s? It sounds like you're using the iTunes hierarchy, which means you may be using its music format. That could be a cause.
Also, this is in the wrong section.

None of it would cause that. Are you sure it's not scanning your media? If not, then I honestly have no idea what you're talking about.

All of my music is in .mp3 format that was organized artist>album>song for iTunes, and it works perfect on my Captivate. If the phone is scanning your SD card, then it will bog the phone down significantly (especially my class 2 16GB external SD...so slow to scan, but cheap to buy).

Did you give it a few minutes for media to finish scanning?

Try a USB port on the back of your computer instead.

I had a similar problem when I first got the phone when transferring a large amount of files to an external SD card. The entire phone would become horribly laggy and even pressing "power off" it wouldn't ever fully turn off, requiring a battery pull to actually restart the phone. I tried loading media onto the SD card directly from the computer and everything worked fine and the phone was able to scan it without crashing. But copying files from external to internal (or vice versa) also caused the phone to react the same way.
The only thing I figure was that it was a VERY low-quality micro SD card (2 GB, not even SDHC, no idea what the class was). When I put in a 8 GB class 6 card, I never ran into this problem again. If this is happening while transferring to your internal SD card, I don't know what the issue might be; but if it's an external, try using a certified high-quality micro SD and see if the problem persists.
edit: I know you said it was to internal SD card, but try removing the external if you have one to see if the issue is still there (the internal would also behave oddly when I had a low quality SD in external even if I wasn't using the external).

SDCard Transfer Speeds

Picked up a Patriot 16 GB card (class 4) and while I know its a class 4, it seems the transfer speeds are fairly slow. Unfortunately I'm in XP so its not telling me what the transfer speed is.
I first put the card in the N1 and let it format it. I then tried to bring over all the data on my old card and it was super slow (like 50kb a sec-was at home and Vista so it told me). Now I'm at work and this time it brought over all my old data more quickly but it still seems slowish (Gonna copy over a couple GB of music today).
Do they just have this slow transfer speeds? Its cool if thats the way it is, I don't mess with SDCards so don't have any experience with them.
Right now I'm bringing over a little over 500 MBs and it looks like its gonna be 30 mins for it to do it at least. The mins remaining is all over the place.
Also, the phone formatted the card in fat32.
I tried the SD Card Formatter download I've seen mentioned on here but it wouldn't install for me on my computer.

Use an sdcard reader. It will be much faster to transfer data.

Yup, faster transfer now.
I knew that but had a brain fart.

very slow internal SD write speed.

I am currently on CheckRom V4, XXLA4 modem, abyss note 3.2 kernel .
now my Internal SD write speed is very slow compare to the others.
in Antutu, it benchmarked 5.3MB/s write speed and 32MB read speed.
I used to have something like 15MB/s write speed on the internal SD, don't know why it slowed down half..
the external sd is fine (Lexar 32GB class 10), 10.7MB write and 21MB read, which is as expected from the spec.
anyone know what happened? anything I can do to get back the internal write speed it supposed to have? Thanks

Bump, someone can help me please ?

sometimes you need to wait more than 6hours for a post to be replied on here have some patience!
what speeds do you get when transferrring files to it? dont always rely on a benchmarking tool for speeds

I am so sorry for the urgency but I kinda worry if my Note's internal SD card degrading or even defective.
I tried copy a 2GB single file from my computer to the Note,
the internal SD write speed reported by Windows is around 7MB/s and the external class 10 SD is around 11MB/s
which is still slow. it used to have 15MB/s + (the internal SD)
Thanks

When you plug it in what does your computer mount the phone as? I.e. Does it assign it a drive letter and call it removable disc or does it mount it as 'phone'.
When i got the phone (so stock rom) it mounted as a drive letter and speeds were good, i then rooted and flashed rocket rom on and then it was mounting it as 'phone' with very slow transfer speeds.
Not sure if this is the case for you but i enabled usb debugging (settings > applications > development > usb debugging) and the speed is back to normal.
Im new to the android scene so not sure if this is even relevant!

have the same problem
Galaxy s3. Since omega v44.x android 4.2.1 my write and read speed are very slow. Gallery and contacts also very slow...
