Why does it come to me when I insert a sd card "the sd memory card is too slow for your device, can have failures when running applications"? Is a sd card from 32GB to 70MB / S
Thanks!!
What SD card do you have? The SD card you have might be too slow in terms of write speed, since Class 10 SD cards are not all the same (confusingly). I think you'll want to buy a micro SD card that has at least Class 10 UHS Speed Class 3 (UHS-3), particularly if you want to use it as adoptable storage. UHS-3 has a minimum write speed of 30 MB/s and the UHS-3 marking can be seen on the packaging and SD card as a U with a 3 inside. I've seen UHS video SD cards (e.g. v30, v60) around that are potentially faster than UHS-3 but I'm not sure if our Moto G4s can make use of the faster speeds.
https://www.sdcard.org/developers/overview/speed_class/ and https://www.sdcard.org/consumers/choices/speed_class/index.html have a good overview, and as an example of what you could buy, https://www.amazon.co.uk/SanDisk-Extreme-microSDHC-Memory-Adapter/dp/B01HXR511A/

I want to get myself a new SD Card for my Magician:
I will choose between a standard 1 GB SD Card and the SanDisk UltraII SD 1GB
First of all, does it really make the difference if i take the UltraII? How much faster is it anyway? It would cost me almost 50% more.
Secondly, can the Magician even handle the Ultra? Are cards up to 2GB even supported?
Or should I consider a bigger card?
Currently I've got a 256 Sandisk standard....

In general you probably won't see the speed deference between the basic and ultra on a PDA, because of the speed of the interface.
If you use a card reader (using USB 2 interface) then you will see the speed increase.
Personally, I've just bought a Sandisk 1GB Ultra plus card:

Will have to wait and see how good it is!
Apparently 4GB sd cards are coming soon, which should drop the price of the 1GB cards even further.

If you going with a 2gb card - go with the sandisk ultra... I purchased an A-Data 2gb 150x and it does not work.
SanDisk Ultra are good cards.
i have a class 2 sd card that is 4gb. i read that you need class 6 for apps to sd card? will it not work on class 2?
It'll work but it'll just lag your phone down whenever any writing is taking place since the write speed is only 2mb/s compared to a class 6, 6mb/s.
Keep in mind that SDHC "class" system is only a guaranteed minimum. There are some class 4 cards out there that actually out perform some class 6 cards. Do your homework (read:google) and get a card that is > 8MB/s write and > 9MB/s read and you will max out the speed capabilities of your G1.
I can personally verify that the AData class 6 8G and the SanDisk class 6 8G both outperform the G1's capabilities. Also, from what I have read, the SanDisk class 4 16GB also outperforms the G1's capabilities.
Also, I have found that even though the SanDisk and the AData cards mentioned above exceed the G1's capabilities, the AData card is a better card for the G1 (in my particular case.) For some reason my Sandisk card can only get 6.5MB/s write and my AData card can get 8MB/s+ write speed on the G1.

i have a class 4 8GB card and i moved my apps to the sd card about a month ago...it was VERY laggy, so i went back to keeping the apps in the G1's internal memory.
i will try again when i get a class 6.
I have a class 2 16GB Sandisk card, and I have to say - there are no lags whatsoever. The card is much faster than the stock 1GB one, and if moving applications, you don't need that much write speed - the read speed is much more important. I can get 14 MB/sec read speed via cardreader with this card, while the stock 1GB one gives 5 MB/sec only (tested with hdparm).
Just remember - move only applications, NOT their data or caches (which is really unstable anyway). You should have no problems with speed this way - application startup is still fast (if a program is 7 MB, it needs 0.5 sec to be read, which is perfectly acceptable), and you still write to the phone's internal memory.
Does it make a difference in terms of Phone performance (Note: Not asking about connecting to a PC for data transfer) for having a External SD card if compare to having Class 5 to better class?

I can't answer for sure but if the sotware sd card speed tester is correct mine is very quick (8/11) and i didn't get a very high score at quadrant benchmark with the minocan fix
Now this benchmark is hard to analyse
It would, theoretically, make a difference if you are using a data on SD mod like minocan's fix. Even then I haven't seen a huge difference between people using cheap class 2 cards and people using class 6 cards. Hell, some class 2 cards are as fast as class 6 cards already. You should test the card you have before you buy a new one.
If you're not doing any mods that put the data folder on the SD card, then for the most part no, your SD card is only accessed to store things like pictures or movies, and even only then if you choose to use the external card.
Also, MicroSD cards come in Class 2, Class 4, and Class 6, and Class 10 speeds. Each number corresponding to their minimum write speed.
if i got the answer correct, you guys are saying its negligible, right?
And this applies towards Samsuing Galaxy S which install the application on Internal SD card... right?
I begin to run out of space and in need of new SD card. What kind of SD card should i use? Van i use sandisk 16GB SDHC class 4. What does the class means?
sent from my Nook Color
Class 4 means the sequential read/write speed is about 5 megabytes per second. This is not necessarily what you want as its the random read/write that dictates most performance, and that doesn't seem to correlate much with the Class from the benchmarks others have done.
Would like to point out that for NC you need a microSDHC card, not just a SDHC card.
From all the data collected so far, 16GB class 4 SanDisk microSDHC card (used as system ROM) seems to be good for NC.
Hi All,
I was wondering if I'm doing something wrong or if it's just to be expected. I have an S7 edge that I'm attempting to move apps to the SD card and they are just painfully slow, if they transfer at all. I'm using a Samsung Evo 128gb class 10 micro sd card. I've also tried a SanDisk 128gb Ultra class 10 card and it was really really slow. Is there some trick to speed this up? Am I using too beefy of a card? Any help is greatly appreciated!!
move the apps always has been slow even in class 10 sd cards, or at least thats what I remember.... but every other thing is just right

The speed of the external microsd card fully depends on the quality and the specs of the microsd card
itself. That's why some microsd cards are slow or super slow.
I have two 128GB microsd cards, one of them is Sandisk Extreme $80 model and it reads and writes
almost 5 times faster than my other off-brand $28 128GB microsdcard. Both microsd cards are class 10.
I am not talking about speed benchmarks, I am talking about real life transfer speeds under heavy usage..
I also have a 64GB off-brand $17 microsd card which is just as slow as my 128GB $28 off-brand microsd.
All 3 of my microsdcards were purchased at Amazon.com
Good luck,
Have a great day!
I have same problem here I have : https://www.amazon.de/gp/product/B00V62XBQQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
And I go 13Mb/S Write and 60 MB/S Read
((((((
same here...
Just got my S7 and transferring speed from PC to external SD is extremely slow (I tried 64GB and 128GB sandisk class 10 which worked great on my last LG-G3...)
I also tried transferring from internal memory to external SD and it was still extremely slow..
Can it be HW problem (I can send it back for refund - but if it SW issue which can be fixed it would be a better)?
