Help Does an SD card help with most apps anymore?

Yeah. I got a UHS1 in my Tab 4. Used to have it in my Note 2. SanDisk actually advertises the UHS cards as optimized for Android.

I believe that the UHS is backward compatible with SDHC, but which devices or Android versions can really take advantage of it? Of course it's optimized for any device that supports it.

I know of no such list. But I know there are ways to test. I remember a thread here asking for info, and someone used a tool to measure write speed of his Android to card and got rated at 20 MBps, hence it supported at least UHS1 since C10 is only 10MBps.

I made a search with A1 SD Bench database and found a Huawei with impressive read/write speed.

Class 4 is the slowest card available nowadays. A Class 10 isn't fast enough. You want a UHS 1, UHS 3 if you can afford. Even then it will still be slower because the fastest SD card is still slower than the onboard flash memory.

I got UHS-I U3 card and it feels much more faster and responsive. Thank you, sir.
 
After a few months the price is bound to come down anyway. Always does with new technologies. IMO early adopters tend to be rich people with a large disposable income.

Any new tablet, so most likely Marshmallow or higher.

They are still selling tablets with KitKat. If you want help you need to give specifics of device and os. The option does obviously exist to install to sd card automagically, but the steps are not always the same to just asking for help on any old android isn't really going to get you what you want.

I have a class 4 microsd card set as adoptable storage and apps that are on it run noticeably slower than if they were in internal memory. Which class of cards do you guys use and what are your experiences with apps performances? I am thinking of getting faster class 10 card but better to ask here first.

Class 10 would work, I've used them. Yes class 4 is really too slow to even try that, tho I have done that as well. I've had good luck with 8+ but just buy the highest class (UHS) with the most storage that you are comfortable spending money on.
 
I have to admit, I still don't quite understand what the answer to my question is. Is it basically, "it depends on the tablet"?

Is it just Amazon's version of Android that allows me to install apps to the SD card? If I were to buy a Samsung tablet, or Asus, etc. is there no guarantee this will be possible? How can I check in advance?

Thanks!

At the moment I don't have a particular tablet in mind. I was just asking if it was possible to install apps to the SD card like I can on my Fire tablet.

I guess I'm starting to see that it's Amazon's version of Android that allows this, and so the answer isn't as easy I thought. I guess it does depend on the specific tablet I plan to buy.
 
It's not just the Amazon tablet that allows it, but it is something you should check for the particular device if it is important to you. I wouldn't like to give a blanket suggestion like "manufacturer X's devices will support this" in case they then release one that doesn't.
 
Almost any tablet will as long as they run Marshmallow. Some will have thr option available, others like Samsung and LG will need an ADB command (no root needed, they just hid the switch).
