Using SD Card as internal storage can it be done?

[s1m0nw]

Heys guys

I am trying to format SD Card to use as internal on my rooted samsung galaxy tab A 2016.

Each time I try it gets to 20% then does a boot cycle.

Is this possible or not? Would be great if it can be done.

Thanks

I wouldn't recommend making a SD card internal storage if it can, it has slower write speeds, knon to crash and create all types of issues, keep. It portable only.

If it only gets to 20% then something is wrong w/the card.

I messed around w/Adoptable vs Portable storage on my LG G Stylo on Marshmallow and it really didn't work too well. The card just wasn't fast enough.

Mustang 757 is right. Don't make it internal. Plus, if you need that much internal, it might be time for a new tablet.

To be honest, I don’t think that doing this is very good. I don’t know how Android handles it, but data probably gets split up between the internal and external SD cards, which increases the risk of data loss.
If your regular external SD gets broken, you “just” lose the files that were on it. If it’s formatted as an internal storage extension, you’ve probably screwed your entire phone. Or what if you want to upgrade to a larger card later on? With an external SD, you can just unplug it, copy the data via your PC and put in the new one. When you’re using it internally, you probably also screw your entire phone.

To be fair, I don’t know if this the case, but if I had to guess I’d say so.

A bit late ... but Samsung doesn't allow an SD card to be set as adoptable storage because:

a) If you lose an app on the card (it corrupts, etc.), you have to reset the phone. The app can't be installed, because Android has it listed as already installed, and it can't be uninstalled because it can't be read. (You also have to reformat the card, and you've probably lost some capacity by that point.)
b) if the part of an app that maintains its current state (all apps do) lands on the card, the card will be destroyed quickly.
c) because the card doesn't last very long being written to constantly, and Android storage gets written to constantly.

It's the one good design choice that Samsung has ever made - don't try to get around it.

The best thing you can do is to move large applications to the micro SD card, using the storage settings for the application. NAND flash cards only have a limited life, meaning you can only write data to them so many times before you start getting errors or failures, so using ordinary internal memory for normal data storage is best, until you can move large files (like videos, music, ebooks, etc.) to the micro card.

"At a sequential write speed of over 1,200MB/s, Samsung 512GB eUFS 3.1 boasts more than twice the speed of a SATA-based PC (540MB/s) and over ten times the speed of a UHS-I microSD card (90MB/s)."

Performance alone is enough reason to avoid using an SD card for primary storage. Even the old eMMC storage used in old phones like the 2013 Note 3 are faster than an SD Card. Any device using an sd card for storage will crawl and feel very dated performance wise.
