Hello,
I have Z3 Dual I am trying to find out the read/write speeds of the internal MicroSD card slot.
I would like to buy the fastest card as I will be using it as the main hdd however there's no point buying a really fast card if the port itself can't utilize the cards max speeds.
Does anyone know?
Thanks in advance!
Hey,
Just tested on Z3 Dual D6633 european model with Goodram SDXC UHS-I U3 capable of write speed 90MB/s and read at 95MB/s which I use with sport camera, on z3 dual I get almost 31MB/s at write speed and 41MB/s at read speed similar results as on z5 dual E6633, tested with androbench and selecting sd for test.

Legend... thanks! Exactly the answer I was looking for. So I guess buying a UHS-1 card would be overkill? What what be the next step down from a UHS-1 card? A normal class 10?
Yup, Sandisk 128GB UHS-I U1 CL10 read is 35MB/s and write 18MB/s so standard for most of class 10 card and price is the same as UHS-I U3 64GB.

Amazon has the SanDisk 32GB Class 4 microSD card on sale for $20.

Before anyone begins complaining about the Class rating, Class 4 is better for storing apps and their data due to higher random access speeds on lower class cards. Higher class cards are rated for sequential read/write speeds, so they are more suited to recording HD movies and file transfers.

If you don't need the higher speed of a class 10 card (and if you're not shooting video you probably don't), this one-day deal is a great price for a class 4.
Does anyone know or have documentation of the speed rating of the microSD card reader?
UHS-I (U1/U3)?
UHS-II?
MicroSD cards have 2 speed ratings:
1- UHS Bus Speed (marked either UHS-I or UHS-II. This is a maximum read speed rating. ) UHS-I is rated at 104 MB/s and UHS-II is rated 312 MB/s.
2- UHS Speed Class (marked either U1 or U3, usually with the numeral inside the letter "U". This is a minimum write speed rating. ) U1 is rated the same as the "Class 10" specification, minimum write speed 10MB/s. U3 is rated at least 30 MB/s.
I am hoping to learn what these ratings are on the SD card slot for my LG V20 US996 Unlocked phone. I don't see this information on LG's website specs, or in the V20 user manual. Any information will be appreciated.
Thanks!
