Guys,
Got a pretty important question; Yes, I've searched. Don't flame the n00b
Using the N1 as a mass storage device, how fast is the transfer speed?
and
Does the speed/class of the SD card make a difference?
Cheers,
It is ass fast as memory stick. Yes, class of sd card makes all the difference.
I was kind of looking for speed in MB/sec
We all know memory can sticks vary from 1MB/sec to 20MB/sec
Fastest I've seen my transfer speeds are 5 MB/s
This very thing is a problem i am having with my N1. i have a 4gb class 6 card in it and when i mount the N1 to my PC i get transfer speeds of 500k to 1mb asec, but then when i plug the SD card into a USB reader i will get speeds up around 8mb asec. I have USB debugging enabled and it doesn't help. So right now transfer speeds to be blow big time. Not sure why it is doing this or whats wrong.
Any info on this? My phone tops out at around 3 megs. I hooked up a Moto Droid and it was moving stuff at 12 Megs a sec.
Experiencing same sluggishness w/ class 6 card.
I think transfer speeds from N1 to PC are independent of the SDcard when plugged in through the USB cable (unless it's like a class 2).
The actual cable and the N1 restrict speeds as long as you're acessing the SD via USB. You're getting differing speeds when putting it in an adapter because the adapter has different transfer speeds and doesn't need to go through the N1 to transfer.
You're going to be capped when transferring from N1 to pc via USB.
on average with the stock 4GB card when in the N1 I see around 1.5-3mb a sec... When I plug the card directly in a card reader I get 5-8mb a sec. It's much faster for me to turn the phone off, take out the card and stick it in a card reader if I'm transferring any more than a few hundred MB.
Just wanted to bump this, as I'm using an 8 gig card, and froyo 2.2 now. I'm getting consisten 3.5 MB - 4 MB, where as before I couldn't break 2 megs. Not sure what class the card is.
Thread update: I now have a Desire with 16gb Class2
7-8MB/sec Writing.
Reading is even quicker.
Transferring a 800mb file to N1 in mass storage (sandisk class 6 8gb) I got about 2.5mb/s using original htc data cable
Using a card reader i got 11mb/s

How is the card reader connected to the computer? Does it go into a USB port or is it a flash card reader built into a laptop?
Wow. 11MB/s is really fast - are you sure of that number? Sandisks are known generally overachievers, but Class 6 is only rated at 6MB/s write so if that number is right then - wow.

Those sound like the theoretical class 4 speeds.
I have a class 6 16GB card and even with froyo, I can't break the 2MBps rate (Running win7 x64).
Stock froyo/FRF50 or a custom rom based on it?
I just recently got my first Class 6 SDHC 8GB card expecting it to be a lot faster transferring than my stock Class 2 4GB. It's the same. But, when I put my class 6 into a card reader, it writes at 15mbps or higher. Sucks that we have to turn the phone off to remove the SD card.
Here are my test results (on the phone, not mass storage), hope this helps.

Hi all
when i bye my viva i used a 1GB micro sd card which was too slow
last week i bought a new one. a Toshiba 8GB Class 4 Micro SD.
its a class 4 micro SD but the speed is the same as my last 1GB MSD.
it takes so long time to copy heavy files using active sync, whats wrong? is that viva's problem? what should i do?
I'll be thankful for any help.
use the Disk Drive mode or use a card reader instead.
no diffrent disk drive mode is the same as active sync.
i used disk drive mode and copy a file to micro sd, it shows 460 kbps!!
a class 4 micro sd card should has at least 4 MBps write speed
and using a memory reader is hard cus everytime that i want to copy
a file i shoud turn off the phone remove the battery and ...
copy small chunks
Don't try to copy GBs together.. break the data into small peaces say 100MB..to copy..
My sandisk card halts copying if i try to copy a big bunch of data in one shot..
Give a try...
maybe the error not with ur sd card ... maybe with the usb port that u using ... use another port hehe try it

The card is class 4.
But the Touch Viva only supports upto class 2. So u will get class 2 speed nonetheless... :-(
sunk8 is right, it isn't a problem with your memory card. Even if you use it in disk drive mode, it's finally comes down to the lowest speed in the chain which is your phone.
Thanks to all
Ok i finally bought micro sd card for my galaxy s. But a problem came up. When im transfering via USB Cable, transfer rate is barely 4mbit/s and when I put it in SDHC adapter and into my laptop card reader, i got transfer rate of 19mbit/s and read speed of 22mbit/s
My question is, can anyone explain to me why is it so slow over usb cable?
Just to mention, I already tested on mobile with mobile software and i got same results as with SDHC adapter and card reader....
Have you tried to put the USB-mode into Mass Storsge mode. Settings->Wireless and Network ->USB Settings ->Mass storage. This mode will only show the internal memory and the SD Card in Windows explorer. I think it is also much faster.
Yup, i tried only on that way tbh and transfer rate is still max 4mbps, and in sdcard 19.47
Weird thing is that i know that i got original card, its not scam, i ordered it from official supplier in my country...
bump anyone
I'm sure I read on a thread somewhere that the phone can't use the speed of a class
10 card and you don't get any faster speeds than a class 4, would like to know the facts on this

Get a free sdcard tester in the market and test it by yourself. I would be really surprised if a i9000 could do above class 6 even after tweaking readahead and buffers.
I tested it with SD Tools and got these results
Mine is meant to be a class 10, not very good result if it is:
I got this result with a Class 2 SanDisk:

hi, i have a micro sd 4gb class 6 and my phone works fine, When i put the original micro sd 8gb class 2, the notification icon of "preparing SD" doesn't dissapper and when the screen go off i can't turn it on because never shows me the screen, only the inferior buttons lights on (nothing i can press) and i have to pull over the battery to make the phone works, i put a micro sd 8gb class 4 and the same happens, i've tried to increase the cache memory to 2048 bytes using "SDBOSTER" and nothing happens with the micro sd 8gb, but my micro sd 4gb works faster.
Can anyone help me to solve this problem? i want more space in my external memory.
I'm using original eclair 2.1-update ROM
Hey jp23,
I recently encountered this problem with my stock 8 GB class 2 card, while transfering files in bulk to the card. I use linux on my laptop and there is a known bug in one of the drivers which causes failures while tranfering large amounts of data in one go. For me it caused the same issue, and thats usually because the card is temporarily corrupted.
For me the fix was buying a microSD card adapter and formatting the card once through the computer and not the phone. I also bought a 16GB class 4 card in the process.
I suggest formatting your card via a card reader or adapter and then trying it on your phone. Although I find it odd how both of your cards can have the same problem. Hope this helps.
I've tried this before and works when the card storage it's <1gb, when i put some mp3 files and pass 4gb or more the same thing happen.
i don't know what to do...

Did you do a scan and repair using windows? That fixes it for me
format it with LLF low level format from hd guru, it always fix my sd card whenever it corrupted.
My card it's not corrupted, i've checked that before.
I bought a micro sd 8gb class 4 and set format as fat32 and put it on the phone, then i connected to the pc using sd adapter to put some music and videos, and when i put the sd back to the phone got the same issue...
I updated to BRAVO yesterday and have no solutions for my micro sd 8gb class 4
i have a similar issue with my 8gb stock sd card too, when i try to open the media gallery or push the media gallery button, my phone shows me that there's a problem with read/write into the sd card... =(
always it says me : "Failed to Read/Write SD Card" and also i cant record any hd video cuze when i try to do it, the video get freeze and stop to record ..
im thinking to buy another sd card, maybe 10 class ..

Here is a reason and fix for this http://forum.xda-developers.com/showthread.php?t=1262030&highlight=failed
But I do recommend getting a c10 card for the speed.
I have same problem, you should update your phone to 2.3, you will out of this.
I just purchased a Micro Innovations Wireless keyboard for my Zaurus-SL5600, but theres a problem; I dont know how to physically set it up to work. I can type with it, and the Z recognizes it fine, but the problem is that the Z has its infra-port on its side, so I cant use the stand The keyboard has it just above the w key, and I dont know how I could rotate the screen.. Does anyone have any ideas?
Yack
Too bad with micro sd
I ordered a Sandisk XDHC from Amazon but it disappeared in transit, so I got impatient and bought a 32gb card from Cex. I'm naturally wary of micro SD cards, and for for the first time today I've attempted to copy some files off my Windows 7 PC's desktop PC - 14.5 GB in total, and it is saying it will take 55 minutes, with a write speed of 4.9MB/s. Am I being too fussy or is this far slower than I should expect. Wondering whether to just immediately take it back for an exchange or to persevere and test with a card adaptor instead of USB mode. Just to clarify, the card says that it is a Samsung Class 10. It looks legitimate under close scrutiny but I'm aware that this doesn't necessarily count for anything.
Cheers guys.
Could be your card reader?

I'm not using a card reader as I don't have one. I'm using USB storage mode. I'm using stock ICS and it's equally slow if I use MTP.
Go to market, download SD Tools and do a test.
That's my result with a Samsung micro SD Class 10 (8GB)
