Hi, today i bought a 128GB microSD card (Samsung Evo Plus) and detected properly by S3. However during file transfer from PC through explorer to MicroSD I got a miserable 100kB/s speed. Yes, it is kB not MB. The MicroSD card should write at max 90MB/s.
I used to get around 30MB/s when transfer to internal storage.
What could be the problem?
Internal transfer from Internal storage to MicroSD card is around 25MB/s
File copied is single movie file 8GB. USB setting is File Transfer.
Regards,
Thanks.
Erm, i am not sure what happened, i changed cable and still getting slow speed. After disconnected from USB cable for a while and do other things, and reconnect again, I am getting around the same speed as internal storage 32MB/s. Really have no idea why i am getting slow speed before this.

when i connect the phone to the laptop with the USB cable and try to transfer files to the SD card (8GB) the transfer rate is pretty slow
but when i take the SD card out and put it in USB adapter the transfer is very very! fast!! why is this diffrent? is there any solotion?
Yes, its allways very slow, on all telephones on the market! You mustlive with it, but i think, you can wait 5 minutes and you dont transfer 8 Gb 2 times a day...
no that's not true. In winmo file transfers @ the same rate as usb (might be a little bit lesser, but that's not noticable).

I think it depends on the hardware, as on my current HP iPAQ 910c (running Windows Mobile 6.1) transferring via USB cable is far slower than transferring directly to the SD card through an SD card reader. I remember trying to transfer a few GB of MP3s via USB, and it was going to take 2+ hours, but only took a few minutes using a card reader.
My Vibrant is topping off at about 12 MB/sec. I've tried several cables and USB ports on my PC. I've also tried with an external hard drive I have that tops off at 60 MB/sec. I thought my Vibrant would be faster at transferring media from my PC.

You are limited by the writing speed of the Internal SD card (hard drive in your phone) which from what I have read is about 13 MB/sec, so you are not very far off.
For reference, the stock External MicroSD card writes at 4 MB/sec so that's the limit of your USB transfer speed when moving file to the external SD card.
Now your external hard drive support write speed much faster than 13 MB/sec, which again is why you see your writing speed top off at 60 MB/sec.
Your Vibrant is designed on the principle of sacrificing speed for portability and durability. The Solid State chips in your vibrant has no moving parts thus, it will not break easily from constant movements. Desktop harddrive usually sits in one location thus can trade durability for speed.
Thank you Sir. I was hoping your answer would be something along those lines to disprove my theory that there was something wrong with my computer.
I have purchased highly reccomended joyflash 16gb, its indeed fast 14MB/s write 20MB/s read..only problem is that when phone connected over USB as mass storage, transfer speed (writing) is only around 4 MB/s and reading is 14MB/s. Both from internal memory and external SD. Anyone idea why is that? Is that a limitation of Samsungs USB interface?
I did testing with SDtools on my device when testing speed of microSD, for transfer speeds over the USB cable i have used total commander
Hey all, just started using ADB to push some video files directly to the internal file system. Noticed that the transfer speed is like 2.3 MB/s which in my opinion is pretty pitiful. Is the Nook Tablet's cable like USB 1.0 or something?
The video files are like 300-350 mb's each if that matters...
Just as another question to throw out there:
If I used a Micro USB to USB A cable certified for USB 2.0, would that enhance transfer speeds or would it not matter and simply depend on the internal storage's read/write speed?
Hi,
I'm looking to get either the Tab or Note 10.1, but need to know whether its possible to transfer images from the micro SD card to an external USb powered HDD. I know I can get hold of a micro usb male/ mini usb male adapter to link the Tab/Note to the HDD, but don't know if the Tab/Note will power the drive, or if it's possible to transfer pics in this way.
I'm planning a roadtrip in the USA later this year and would not have regular access to wifi to upload images to 'dropbox' etc so would rather back them up to a HDD.
I know there are several similar postings, but no suitable/applicable answers.
Suggestions/answers ?
Cheers

The Tab 10.1 doesn't have a micro SD card slot - the Tab 2 does. On the Tab 10.1 there's a chunk of the internal memory mounted as /sdcard that you can store your photos on.
As far as moving files to an external drive goes, you can do that with most file managers so that's no problem.
One issue you may have is that the external drive will need to be formatted as FAT 32, not NTFS. That means that you can't copy files larger than 4GB to the external drive. That's probably not going to be a problem for you if you're moving images (not movies).
To connect the drive, you'll need an OTG cable, which are fairly inexpensive. However, there's no guarantee that the tablet will be able to power the drive. External thumb drives work fine for me. I haven't tried any portable hard drives, but as long as the current demand is fairly low it may work. Some people have had success with portable drives, so it's worth giving it a try, especially if you're talking about a notebook size drive as those tend to be less power hungry.
I have successfully mounted an external HDD via a externally powered USB-Hub. The FAT32 partition can be mounted without additional software, the NTFS partition can be mounted with the free app "NTFS mount". USB-Sticks will be powered by the tablet without problem. The problem is, that the combined card reader / USB adaptor can only be used with one function at a time. So I had to copy the SD-card to the internal storage of the tab and then move it from there to the external HDD.
You might want to think about buying an Intenso Memory 2 Move HDD. It's an external 2.5" HDD with a battery (6 hours) and a wifi hotspot. You can access the drive via wifi, ethernet RJ45 and USB 3.0. Works like a charm with Android.

Sorry, it was the Tab 2 (10.1 screen, stylus thing etc) I was meaning but couldn't find a heading for it. Is it likely to power an external 2.5 drive ?
Most certainly it will not power HDD. The easiest solution is an external miniature USB hub with power supply.

I would like to mention that HDD must be partitioned as GPT to work otherwise it shows as corrupt.
