Hi you are using this in a device that uses USB2 interface, and that is your limiting factor of getting anywhere near the speeds the card is capable of.
You should be getting about 20MB/s write out of that card approx, and I have now looked at your post and sure enough
The fastest card in phone is the Sandisk Extreme Pro card at about 40-45MB/s write, the maximum transfer rate for the phones interface.

I see what devices then would support UHS1? I have a desktop PC and laptop and they are USB3.0 but still showing 20MB/S. So my speed on this phone is normal right?

I get 50MB/s read, 45MB/s write from my 64GB Samsung Pro. Make sure it's not the orange Evo, that will top out at 20MB/s write. I used A1 SD bench in my D6616 to get those numbers.
Yes it's not the orange. Its the white one I got from eBay. Im staring to think this os just a Samsung evo dressed to be a pro. Can you try using sd insight and view info for the card? I also use Adata to benchmark.

yeah that looks more normal. Looks like you have a TON of stuff running and going on, something may be accessing your card, altering the results. The card is good for +40MB/s writes.
To test the legitimacy of the Samsung Pro card (for speeds), try to benchmark this on a PC/Mac as well.

Well I benchmark on my laptop but it's a 2 yr old Laptop and I guess the card slot don't support uhs-1 only usb 2.0 so it was slow and my desktop is good but I don't have a decent usb card reader as well but I already tested for capacity and there were mo issues.

You will need a card reader like the lexar professional USB3 card reader with UDMA support to get the top speeds from the card.
Good to see Samsung has caught up now with similar speeds

In searching the forums I know this has come up for other devices and am wondering about the Fuze. What Micro SD speed class can the Fuze use. Don't want to spend extra on a class 4 if it can only take advantage of the class 2 speeds.
Thanks, my Fuze gets delivered late this week, cant wait

I'm running an 8GB class 4, Although I've seen specs that say it supports up to 32GB storage and class6 speeds
I'm rocking a Mobile Ultra 8GB... class 6.
While the fuze (and any phone really) can only take advantage of class 2 speed, your computer can use everything higher. Also, I believe when you're using the direct storage card access mode while plugged into the computer, you can take advantage of the higher speeds as well.

I Noticed a speed tweak in the Blackstone forum for making the SD read time 3X as fast. Is there any way to "port" this setting to the Fuze? I'm beginning to load up on movies and want the best format possible for TV-Out.

I just installed that tweak and, at the very least, everything seems to be able to access the storage card normally. I don't have time to try it out myself right now, but I'll see if I can slap some videos on there for testing later.
I wouldn't let thos Class numbers fool you.. I bought an early 8GB Adata Class4 card and just recently a new 8GB Class6 for a neighbor. Just out of curiosity I plugged each into a mini USB reader and ran hdtach on my PC. My old Class4 card read at 19MB/s and the newer Class6 at only 14MB/s. Explain that...
I have two 8 gb cards, one is class 4 and one is class 6. The difference when connected to a computer is around 10%, but on my Pro I didn't notice any.
However class 4 is almost 2x faster than class 2, and I believe that will have an impact on phone performance.
I could benchmark mine if someone recommends a tool.
I'm running a Sandisk 16 GB Class 2 in my AT&T Fuze,and it runs great!

Depends on the brands and models you got as to what your read speed will be, but the class rating actually has nothing to do with read speed, only write. Also, the class numbers are a guaranteed minimum write speed, so a card labeled class 2 could write faster than class 6 in theory. Here are some read-write benchmarks to show you just how they can vary:
http://www.extremetech.com/article2/0,2845,2094715,00.asp
I haven't found any info on the max theoretical read/write speeds of the flash controller in the Fuze/TouchPro to know what they're supposed to be capable of.
As for the speed tweak from the Blackstone forum...I can't see any difference in playback speed using one Xvid and one Divx video in TCPMP's benchmark. Those are the only two formats I have atm, and they're both technically just MP4 video with MP3 audio.
pocket mechanics can benchmark the sd card in the pda
as benchmarking can't be don on the pc as the speeds will be way different
I think I actually have a copy of pocket mechanic. I was thinking about using SPB Benchmark, but I'll give PM a shot first.
http://pocketnow.com/index.php?a=portal_detail&t=news&id=6415
Article on the cab file and post in the blackstone forum. This article has benchmarks in a graph showing the increase. Anyone benechmarked this tweak on a touchpro yet to see if it works like the HD does?
I have to say that I'm pretty surprised by these results. Both tests were done under identical circumstances and both probably suffer a little due to the fact that I had SOTI Pocket Controller running while I ran the tests. I used the latest version of Pocket Mechanic and an Adata class 4 8gb microsdhc. On the left is the "before."

Yes. Unfortunately, throwing all that extra data at a video processing system that was already choking to death hasn't helped video playback, which is one of the main reasons the patch was developed for the HD. I think I may try to flash the HD derived rom to my Fuze and then retest to see what happens.
If we had the right software to take advantage the hardware we could play DVD,s off this thing
I tryed a full 700meg divx dvd rip that stuttered on play a bit before the cab install, and it plays pretty decent now. It had to be the read time of the phone and not the card that was doing it. Now if coreplayer ever fixs the QVT (blue flicker) on there player it would be a neat toy to plug in with the tv out cable.

hi all,
i got my A9 2 days ago and have a fault with it rebooting randomly and will be getting it replaced,,
but my question is about the SD card aspect..
i fitted a Lexar 64GB Class 10 High Speed Micro SDXC Memory Card and after formating as internal and migrating the data i had a system message saying that the card was slow and suggested using a card class 3 or better.
is this normal? have not noticed any performance issues since doing so.. just curious to see if anyone else has had similar messages after putting in the SD card.
I might be off base here, but is it possible that the card itself is a fake? Have you run a speed test on it?

have run a couple of tests but not sure what speeds i should be getting for this card..
cant post a screen shot yet as im a new user..
the results from an extended accurate test
are
1.52 GHz
read 38.6Mb/s
write 38.6Mb/s
when running one of the tests it did say that its cached the data as either there was too much free space or the SD card is slow.
Honestly, that's a little weird. The results seem a little low for a high end new card which should have speeds of 80Mb/s and up, but also too high for a fake which is usually lower than 10Mb/s.
Since you're getting the device replaced anyway, it might be a good idea to re-check once you have the new unit just to make sure it isn't some bizarre issue with that specific handset.
To compare, I've currently paired my A9 with a 32GB Samsung Pro card, and haven't seen such a warning message.

what speeds are you getting?
I have a SanDisk 128GB class 10 and I get 43.70MB/s read and 12.45MB/s write using A1 SD Bench.
I just bought a Samsung Pro Plus 128GB SD Card but it's very slow.
A1 test result was R:59MB/s W:28MB/s
I am fully aware S7's SD interface not good enough for the card's full speed(R95/W90)
But from what I read elsewhere, at least it has R70/W60 in A1 TEST.
My result is way below. Any idea why? Maybe I need to format the card to specific format like exFat? Thanks!
The speeds sounds about right. It's the S7's SD card interface that's the problem. It seems to max out about 28 Mbps write and depending on the card anywhere between 60-70 Mbps read. So yours seems to be good.

Mine is also slow. I too noticed it from day 1. Samsung is not dump to giveaway high class 128GB cards to everyone. Most of them should have got those which didn't even pass quality testing.
hardware and/or software limitation. that card can obviously do faster.
chances are it wont be addressed, ever, sadly, which is a shame, so is sammy not offically working with adoptive storage out-of-box, but that has its own issues and limitations.
So I bought a Samsung EVO+ SDHC card on Amazon and I am trying to figure out if I got hosed. It is a UHS-1 card and is supposed to get write speeds up to 20MB/S, but I am getting 5-8... I have it mounted as an external card. I've tried 2 different speed test apps on Android. Do these speeds sound like what I should be expecting?
When I put the card in, I originally set it as internal, but the phone gave me a warning the card was slow (another not-so-good sign).
Should I try to return it to Amazon and just buy some place locally?

I bought this SanDisk Extreme 64GB MicroSDXC UHS-1 card about two weeks ago, working great! No speed warning when I set it as internal. Rated up to 90 MB/s, and I just measured 61.82MB/s Read & 55.87MB/s Write. Maybe you got a knockoff?
This is the one I got: https://www.amazon.com/gp/product/B0118LR9Z8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
Which app did you use to test the speed? I am wondering if my issue was that I was looking at random write speeds instead of sequential. I found several references around the Interwebs that show similar performance. The faster speeds seem to be sequential writes..? Could that be my issue?
One of the apps I tried did identify it as an actual Samsung card, but perhaps it was a slower class card relabeled?
I used A1 SD bench.
I tried 2 different Evos and can Evo+ and the phone didn't like any of them.
I had to but a Pro+ for it not to contain about the card bring slow.

Note - the Samsung card is a U1, compared the SanDisk Extreme which is U3. Big difference, lol. Make sure to get a UHS-1 U3 or higher card to eliminate speed issues.
Been using a 200gb that came free with the purchase of the V20. Gonna pass this off to my son. I'm running out of room and wanna carry more. This 400gb should give me enough room. ?
Anybody else using one in the v30/+?
All set up. 367gb free. I can pretty much use the internal 128gb for whatever phone wise (apps), and this for the downloads and music (I store mine locally). I do have a streaming account though, but prefer my collection on my SD card.

I ordered a 256GB card from that page -- which eventually will be in addition to my 128GB V30+ when it comes.
Now trying to decide what my wife's LG V30 will get. That 200GB is only $73 right now and looks very tempting for her phone.

$73 for a 200gb doesn't seem bad, it's actually a way better value compared to the 400gb. But I was going for size. My 200gb held up well for the time I used it though.

Using "A1 SD Bench" gives the results posted below. My PC doesn't have USB 3.0 yet as this spring is my lustrum update year for the motherboard, ram and CPU. So it's not really worth testing on there.
Edit: Results posted on the following post. I forgot to attach them and edit mode didn't give me the option of doing so.
Forgot results.
If anyone wants some stats on the card here is an post from the V20 forum and what I got of test:
Okay I got the Card of SanDisk Ultra micro SDXC UHS-I Card 400 GB "Well actually less then 400 GB because of companies continuously lies which seems to be of no end to it" and it is running much faster then my old samsung 128 evo or evo+. It's not running as fast as your 128 GB samsung pro+ but anyway il find the results. Iv made test with 3 programs on the V20.
First one is A1 SD Bench which you used:
Read 78.14 MB/s - Write 41,21MB/s
Read 78,19MB/s - Write 41,37MB/s
Read 79,45MB/s - Write 42,97MB/s
Read 78,50MB/s - Write 41,07MB/s
Then SD Card Test
Read 88 MB/s - Write 42 MB/s
Read 87 MB/s - Write 42 MB/s
Read 88 MB/s - Write 40 MB/s
Read 89 MB/s - Write 42 MB/s
and last without any advertising AndroBench:
Read 84.16 MB/s - Write 46,59 MB/s
Read 84.39 MB/s - Write 50,16 MB/s
Read 84.81 MB/s - Write 53,23 MB/s
Read 84.25 MB/s - Write 55,9 MB/s
As you can see the write is far from as good as the Card you had of 128 GB... But of cause this is 400 GB and still a good deal faster then my old ones I had. Put a lot of stuff on it already. I also found out my Laptop is getting old as it corrupts the image of the UHD video when playing.... My Mobile seems to actually have more juice in that department then my laptop as it runs fine on the mobile. I tested which quality I wanted to run on my mobile for best video results and used the Pagan New Year in the Winter for it. I did a look at it yesterday and It seems FHD and 60 frames a second gave the best results on the V20.

Flash memory has a finite number of writes to each page before they 'wear out' to some headroom is required to spread out the read/write cycles and manage the storage. This headroom is the difference between the actual size of the card and the amount you get to use. It's called wear levelling. An explanation can be found on Wikipedia.
400GB is a lot! If you use a program like Aftiss (which is on the forums, just give it a quick search) and use the setting "0" when formatting the card, that whole 400GB will turn into Internal Storage. I have it set up that way on my Verizon V30 with a 128GB microSD Card. Just do a backup beforehand just in case anything goes wrong (which it shouldn't.)

Probably not since the microSD becomes the internal storage where all of the "active" system & app files (user changes) are stored
edit:
the following should explain it
https://fossbytes.com/android-sd-card-internal-storage-adoptable-storage/
so it might be possible, but there are possible consequences (data corruption, system messed up, etc.) - a reject beforehand is highly recommended

Oops! Didn't see this reply. You are not able to remove the SD Card, well at least not recommended to, because if you removed it and some apps had placed necessary files on it, they won't be able to run. I would strongly recommend against it just because of the dangers that could come with it.

Most harddrive makers and memory card makers has always cheated with the real amount of space.
The last company I know that kept the rules of real storage was IBM who made the Deathstars as they sadly ended up being known by. They then sold there harddrive line to another company, Hitachi or something I think it was. But the thing is when you bought a 20, 40 GB or 60 GB harddrive from IBM you actually got those GB and no cheating.

I rather not as I many times pop it out and into my computer - I don't have time for the stupidity of connecting the phone to the computer and having all these issues with it which should not have been. So mostly because of frustration I end up just popping the SD out of the phone and putting it directly into my computer. Then you can do multiple things on it without any error popping up and have top speed.
I'm using the 400GB with my v30+ simply for Rom back-ups and storing my music.
