So, from what I gather from this thread is this card :

https://www.amazon.com/gp/aw/d/B013...card+uhs-1&dpPl=1&dpID=41+DP3+vaOL&ref=plSrch

Would be a good option? They also have the Kingston posted above for a little more. I'm not well versed in SD cards. Would one be a better option than the other, despite both being UHS 1 - U3?
[HTC 10 Questions & Answers] alexp999:
Just at quick glance, the Sandisk is 40 MB/s write vs the Kingston I posted was 80MB/s. Not necessarily a big deal, both fine for 4K recording, depends what you want to do with it. The kingston should be a bit quicker loading on music for example.

There might be other pros to the Sandisk though, I only looked quickly.

[HTC 10 Questions & Answers] codeglitch:
the speed is not even a contest on those, extreme plus is the winner unless you count the new Extreme pro :D

SanDisk is probably the way to go, just decide what space you need and how much you can afford

Extreme Pro

Read Speed	up to 275MB/s

Write Speed	up to 100MB/s

Extreme Plus

Read Speed	up to 95 MB/s

Write Speed	up to 90 MB/s

Extreme

reviews of the cards say 4k work fine
[HTC 10 Questions & Answers] alexp999:
It depends on the bitrate, Sandisk make no mention of write speed and class 10 only guarantees 10MB/s.

U3 (UHS-1 Class 3) is designed for 4K and guarantees 30MB/s minimum.

[HTC 10 Questions & Answers] combatmedic870:
Currently, the fastest micro SD card for our phones is the Samsung pro +. It's ever so slightly faster vs the SanDisk extreme pro u3. The uhs2 cards in backwards compatibility testing were actually slower vs these 2 cards. They are the fastest you can buy. I have a Samsung pro + and have no problems playing games I transferred onto it ect... Not all U3 cards are created equal. The 200gb SanDisk sounds like a good deal. But it's slow as a dog. If the card is cheap, you'll probably get what you pay for. I've had 2 cards fail on me in 7 years. Once you have one fail. You'll never buy a cheap one again. SanDisk ultra isn't known for its longevity. They had a rash of failures a year or 2 ago. Think about what you'll have on your phone and how often you personally back up on your pc. If you keep tons of pics and videos and only back up once a year. You may want to spend the extra on a good card like the SanDisk extreme pro u3.

End rant.

The better 64gb u3 cards:

Transcend ultimate 633x

Samsung pro

Samsung pro +

SanDisk extreme plus

SanDisk extreme pro

That's about it. The random read /WRITES on anything else are rather slow. Mostly below 1mbps.

Also note. The largest card you can buy that wont cost more then you phone is 200gb. Period. Anything else is fake. These cards are heavily counterfeited and faked. Only buy from an authorized dealer.

Not even reaching that, less than 35MB/s write speed. Where as random 4K read is below 4.7MB/s while read is just 1.3MB/s.

[HTC 10 Questions & Answers] blacksmithjim:
I read in a comments section, that what is important for adoptable storage is random write speed not sequential. Most speed tests for Sandisk report High sequential write speed, but low Random write speeds. The samsung evo+ cards have some of the highest random speed tests, but only speed class U1. Does anyone have more input or insight to this?? Thanks!

http://xdaforums.com/showpost.php?p=66417039&postcount=9

tl;dr For adoptable storage

SD card manufacturers do not advertise random 4K read/write numbers so you will have to do the research yourself.

Search by microSD card make/model CrystalDiskMark. Only pay attention to

"4K" results

, not "4K QD32" or "4K Q32T1".

Be careful what results you're looking at. Different capacities perform differently and also as an example Sandisk's model names confuse the image search so yeah, don't just look at the images and take them for granted, go to the page and see what's the exact model he/she tested.

Another good place is to look at Amazon, Newegg etcetera user reviews if you can't find any CrystalDiskMark numbers through Google image search. There might be some kind soul who has ran the benchmark and included the numbers in his/her review.

What I do know is that for example those Lexar 1800x cards are insanely good, 64GB microSDXC 15MB/s read and 2.7 write but pricey as well because they're UHS-II U3 cards..

Sandisk Extreme (

just Extreme

) 64GB has almost 10MB/s read and 3.5 write so it would be better balanced.

Over 2500 IOPS for 4K read should be plenty enough for smartphones. (10MB/s / 4KB) *1024 = 2560 IOPS

But that 3.5MB/s 4K write is insanely nice.

Anyone having speed issues with their SanDisk Extreme Plus?

I purchased a 64GB (U3) and while it benchmarks fine on CrystalDiskMark it performs poorly in my HTC 10. I also have an older SanDisk 32GB Extreme Plus (U1) that benchmarks similarly in both Crystal and the 10.

[IMG="SanDisk Extreme Plus 64gb CrystalDiskMark"]https://i.gyazo.com/7be74c7e5a94dacfb28169371497859e.png[/IMG][IMG="SanDisk Extreme Plus 64GB AndroBench"]https://i.gyazo.com/9becca328f9a30265b7385adc9b6d0cd.png[/IMG]

However if I plug my "slower" Samsung 64GB EVO into the 10, I get better AndroBench marks.

Edit:

My Lexar 32GB 633x U3 card performs similarly poorly on the 10.

---------- Post added at 04:26 PM ---------- Previous post was at 03:39 PM ----------

I guess based on my results I'd be most interested in how a Samsung Pro performs, seems to be the best bang for the buck if it doesn't suffer like the SanDisk. I'll be returning my 64GB SanDisk to BBuy and purchasing a Samsung Pro 64gb to give that a try.

---------- Post added at 04:50 PM ---------- Previous post was at 04:26 PM ----------

One more reference point for the older SanDisk Extreme Plus 32GB U1.

Question: which would be better, a 128GB U1 (60MB/s) microSD card, or a 64GB U3 (90MB/s)? They're both the same price but I don't know if speed is more important than storage (and if I'd actually use all of the storage haha). It'd be for expandable storage, not adoptable if that helps :)

The Snapdragon 820 only supports SD specification version 3.0 so no, the 10 does not support UHS-II, only UHS-I (U3).

But I wouldn't say you wasted your money though, the 1800x is an excellent microSD card with fast random 4K read/write numbers so it should be really nice in Adoptable Storage use.

P.S. It always useful to check for this kind of stuff after you purchase something. (read: i know the feeling)

All my apps/data/cache going to Internal Storage.

Phone storage always is empty and cant move on phone storage.

On sd card i can move all apps because i have rooted device.

I want cache and data move to sd card or bind auto going to sd card folder like "data" "cache" and other..

No on internal storage. Because i need more spaces.

Internal storage its 1gb.

SD card: 16gb

Don't feel so bad about not receiving any replies on this forum. I have been flashing ROMs through this forum since Windows Mobile 2003 and in that time, xda-developers has become so big and unwieldy that it is VERY difficult to find a forum where people who know the answers can even see your question.

I have been asking essentially the same question as you for over four months and in that time no one has seen the question OR some newbie organiser has moved it to an obviously wrong forum solely to annoy the forum members there! It isn't clear who is running this forum any more but unlike the old days, no one seems technical any more unless they ACTUALLY POST to specific forums.

Do we have the same phone? I have an alps/MT6571 (possibly made by a company in China called HDC) with 16 gig of storage, nothing whatsoever in it and mysteriously no space left (with a few hundred meg showing available most of the time). Something in the extraordinarily badly written ROM (Hexing71_et_lca) is stopping the OS from addressing the storage space.

I even tried prising the back off the phone carefully and inserting a 32 gig sd card in it and designating that as the phone's storage but now the device reports the SD card as storage, there being 32 gig of storage, still nothing whatsoever in it and still mysteriously no space left, still with a few hundred meg showing available most of the time. Something in the extraordinarily badly written Hexing71_et_lca ROM is stopping the OS from addressing ANY storage space!!

Seems like the same phone? No one here knows the answer and no one will accept your challenge. A few users have reported this problem with this phone and this ROM on www.china-devices.com and no one there knows the answer either. There have also been postings on needrom but all trails there have gone dead as well. It seems everyone tries to back up their ROM to SD card, then they try to figure out what is wrong and then so much is wrong with it that everyone gives up.
