does the speed of the SD card makes any difference on the universal? and which is better to use SD or MMC?
SD. Speed doesn't make much difference as the read is slow. I have a 2GB Sandisk Ultra II and I am happy.
I'm using sandisk extreme III. It felt faster downloading, copying and installing files then my normal speed Apacer sd card.
Hello.
I got a question to You about write/read speed in our I5800.
Because I bought micro sdhc 8gb class 10 card (GOODRAM) and I tested it in Antutu benchmark. Write/read was about 4.5-4.8 Mb/s.
But in PC I tested it and I have read:20 mb/s, write 12-14 mb/s.
So, I5800 can't handle class 10 card?
Please, write in this topic Your Antutu scores of SdCard (and which card and class You use)
Greetings.

Well the phone limits the read write speed somehow that s what I ve heard. Why don t you try the SDCard reading speed fix??
Because it may cause lag in playing videos. Or I'm not right?

just read in a german board that there is a conjunction of:
class and size
so:
a class 2 1GB may be faster than 16GB class10
and
class 6 may be the fastest that may be "supported" by the G3, so class 6 is the "fastest" really usable speed in G3 due to G3 bottleneck
all above is waste of money
just ordered class6
4, 8 and 16 GB
cards to verify theory above of speed and capacity in different sizes
keep you updated
Waiting your tests...
tests done
and here are the results:

-antutu bench is done on mobile phone direct
-PC-USB: the sd card is connected via USB mass storage from mobile to the PC
-h2testw PC: the sd card is tested directly in a sd slot
all values in MB/s
I just wanted to share some of the information i found.
I'm currently using Micro SD from Sandisk called Sandisk Extreme. The card have speed of 60mb/s Read and 40 mb/s Write. I used an app called A1 SD bench to test the card speed on my phone.
The result I got on my Note 3 was 19-21mb/s Read and 9-14mb/s write. As you notice even though my card should have higher numbers but I think the Micro SD reader slowing it down. Now that I have the Note 4 the result is amazing. I have 59.8mb/s Read and 38mb/s write. The numbers are very close to the advertised card speed which is great.
I though I will share this information just so you know that note 4 does benefit from higher micro sd card speed.

Damn! I knew I should have bought a faster card.
Thank you for the info!
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/
Very slow sd speed formated as internal, what are you guys getting in a1 sd bench?

"slow" means what speeds exactly for you?

What SD card do you have installed, and is it a Class 10, or a UHS-1 or UHS-3? The type of SD card and what it's rated for will heavily impact your expected speeds, especially if you adopt the SD card.
Though my SD card is not formatted as internal storage (and thus not subject to encryption, which may slow down the read/write speeds), I'm getting similar speeds to what my SD card is rated at.
SD card: Sandisk Extreme 32 GB (UHS-3, v30 rated, up to 90 MB/s read, up to 60 MB/s write)
Formatted as: portable storage.
System: stock 7.0 June 2017 security patch, NPJS25.93-14-8.
A1 SD: 81.9 MB/s read, 51 MB/s write

Uhs1 I wonder because encryption it bogs down the carx

It's definitely possible as UHS-1 cards are rated for a minimum write speed of 10 MB/s. Encryption and being adopted as internal storage may decrease that write speed even further.
You could try formatting the SD card as portable storage, see if speeds improve (plus apps will behave better if they're kept on internal storage, widget work and they launch faster).
If you're still intent on adopting cards for internal storage, I would want to consider UHS-3 as a minimum rating on SD cards (minimum write speed of 30 MB/s). They're more expensive, yes - but the faster the speed, the fewer issues you may run into.
