my link rate on the phone is 525Mbit/s and my computer is at 1Gbit/s and for some reason im transferring from my computer to my phones Memory card which is a sandisk 128gb and im only getting around 1-3 MB/s write speed, i don't get it shouldn't the sd card be rated for higher? or is it the chip inside my note 4 that bottlenecks the sd card? im using Es media to transfer the files. And no it's not small files it was around 800MB
Write speed to your SD card (external storage) from your pc to your device is slower than transferring the file directly from your pc to your devices' internal storage.

but how can it be so slow? is it the phone storage controller that's bottlenecking the sd card?

I'm not quite sure about that. But I think one of the reasons is the SD card itself. Try to use a microSD adapter, plug it in your PC and transfer a file to it. Is it a lot faster that way?
yeah i can get like 12 MB/s

i have a sd card (1 gig) but it takes ages to transfer data to it..
for example it takes up to 50 min ot transfer 250 mb
is this normal? this really sucks!!!
Are you using a card reader writer or using activesync direct to your phone?
now activesync but i tried a 1.1 usb card reader writer and it was still crap!
well if it's also slow with a sd card reader then it's not really sd related and the only thing people can say to you is
1 try an usb2 reader
2 get a faster sd card
Hi all,
Was just wondering if the memory card is hot-swappable? Transferring files over the PC is painfully slow. Also, a cheap microSD reader would let me use the memory card as a USB drive as well when I need to transfer stuff in a hurry..
OK just found out that it is. Hooray!
I've noticed that copying files to the phone (to storage card) via USB cable is painfully slow (as compared to say regular USB stick).
Would purchasing a high speed MicroSD (e.g. Sandisk Premier) help or is the phone itself the bottleneck?
Thanks!
Try connecting your phone as a mass storage device, if you haven't done that already.
You can select this when you plug in the usb cable.
Accessing the storage card is way faster then.

I have purchased SanDisk Mobile Ultra (Class 6) and the performance increase in real terms is marginal!

It would certainly help. Also search this forum for tnyynt's SD Tuneup cab. Note that installing that cab only makes much of a difference once you got a faster SD.
The transfer speed of the SD is limited for whatever reason, power preservation, whatever, it's limited to optimize for slower SD cards. So The SDTuneup cab ups this limit, meaning you will notice a much bigger speed difference when using faster SD cards.
i also find the msd card speed poor. especially when you open up a folder with a lot of images every image software takes minutes to scan the folder.
that is very lame
Hi I need more space for my duo 11 and the cheapest way i believe is to buy a micro sd card to increase the size(Don't know if i can swap my hard drive from 128gb to 256gb). I spotted this micro sd card which is pretty good but don't know if i can utilise it to its maximum speed. The card is "Samsung UHS-1 Class10 PRO Micro SD XC 64GB Memory Card", I know duo 11 supports SD XC but it also needs to support UHS-1 for it to use it up to its maximum speed.
On a side note it says
-Read Speed: Up to 70MB/s
-Write Speed: Up to 20MB/s
Does take mean if i transfer files out of the sd card it can go up to 70mb/s and if i want to transfer files from my hard drive to the sd card the transfer speed would be 20mb/s??
Thanks in advance!
That would be the correct speeds assuming all is perfect and no overhead.
You also need to verify that the reader in the Sony is not connected through USB 2.0 or you wouldn't see 70MB/sec reads, more along the lines of 30-35MB/sec.
The duo uses sd cards not microsd. You can use a microsd card with an adapter but a sd card will be cheaper.
I have a 256gb sd card in mine and it works but it's not particularly fast.

That would be the limiting factor as far as the SD card is concerned yes. Operating system overhead would slightly reduce that. Also there would be a limiting factor in what the hard drive read and write speeds are or memory stick or whatever it is the files are being transferred to and from.
Im not sure if i choose right section but:
I bought Samsung micro sdhc class 10 64gb and read speed is ok, but write speed is so slow. On cover was printed write: 7 mb/s but i getting just 1-2 mb/s sometimes 4.75 for second.
If i downloading with steam to that its downloading few secs and then steam say disc busy and origin downloading max 300kb/s (normally to hdd downloading 2,5mb/s)
Any ideas what i can do for better speed?
I'd try to re format the card and pay close attention to all of the options before finalizing the format.

Tried... NTSF/exFAT still incredibly slow.
can you state clearly what devices you used with your SD card ?
SD card
Have you ever used the SD card via the reader on your laptop/desktop before?

Yes its same speed. And i used only my PC and TabletPC (ASUS T-100).
