Using SD Card as Internal Storage dramatically slow

lerouxjul · 发表于 2017-01-09 03:05:44

I have two Beelink GT1.

- > The first one uses an Integral 128GB UltimaPro MicroSDXC Card 80MB/s.
As Android 6 allows this, I use this card as part of the device’s internal storage. I have a total of 144GB on this Box

-> The Second one have no Micro SD card inserted and just have a total of 16GB.

For my exemple, I install FIFA 16 Football via Android PlayStore that is a beautifull but big game.
Link here : https://play.google.com/store/apps/details?id=com.ea.gp.fifaworld

-> When I load the game on the first one with 144GB, the game takes about 25 seconds to full load.
-> When I load the game on the second one with 16GB, the game takes about 6 seconds to full load.

I tested on my Windows 10 PC and the read speed of my Integral 128GB UltimaPro MicroSDXC card is about 74MB/s which is rather fast, I think.

Who want to do the same speed test ?
What do you think about that ?

Nobody uses a MicroSD Card merged with internal storage ?

I think maybe, iirc, the GT1 can read/write to microSD at 20MB/s, so this is why.

Hi,
Thanks for answer.
I don't think so because when I insert MicroSD in my second GT1 without merging it with internal memory, FIFA 16 Football once installed on MicroSD load very quickly.

GT1 max sd card support 64gb

No, 128GB is totally recognized by Beelink GT1. I'm not the only one here using more that 64gb, and this has nothing to do with read/writing speed. If GT1 max sd card support was really 64gb, my card would not be recognized at all !
Moreover, I have a 64GB card too and I encounter the same problem when merging it with internal memory...

I'm sure, you will have to same phenomenon with your 64GB card
Do you try my speed test with your Beelink GT1?

TV box TF slot is much slower than PC card reader. You won't get full speed for both read and write like PC.

No, you don't understand.

The speed problem only occurs when I merge with internal memory. When I don't merge internal memory, I can use SD card and it goes very fast !

Your game is installed on external SD card on Adoptable storage mode, right?

When I install the game on external SD card on Adoptable storage mode (SD card merged with internal memory), the game is loading very slowly.
When I return into Android normal mode, then I install the game on external SD card in old Android Mode (not merged SD with internal memory), the game is loading very quickly.

I just would like to explain to you that it's not an SD card speed problem but just a problem relative to Android bad Adoptable storage mode.
