Can the S7 edge utilize the top write speeds of the best UHS-I cards? Some people say it cannot but I think they are referring to UHS-II cards. My current card is rated at 40MB write and does 38MB. A 60MB card writes at 58MB.
I want to know If i buy an Samsung Evo Select if I cant expect it to come close the the 90MB advertised write speed.
Thank you.
Well I confirmed through my own testing what I had feared. I got a 128gb samsung evo select. When transfering data on to the card via the adapter in my imac it was writing at around 90MBps as advertised. In my S7 edge it only writes at 40MBps. So if ur considering buying a fast card for your S7 edge you do not need the fasted cards.
And what android app did you use to test the write speeds? I have a 128GB samsung evo (not the select model) myself & have no issues with the speeds. It's possible that yours is a defective MicroSD.
Read 54mb/s, write 37.3mb/s. Samsung evo+ in my S7 Edge.
A pleasant increase from the old class 10 (14mb/s write speed) and makes the gallery, file transfers etc MUCH snappier. Compared to the old class 10 cards it also runs cold in an external reader, the class 10 was too hot to touch !.
I'm VERY happy, I'd no doubt get faster speeds in a card reader but it's a joy to use in my s7 edge too. I'm also pleased it doesn't add to internal temps (latest technology memory chip used !).

Hi,
I have recently purchased a PNY 16GB micro SD card from play.com, marked as class 2; the strange thing is that the card came without the PNY brand and that made me a bit suspicious... it is marked C16G "Made in Japan", it looks like a Toshiba...
Anyways I did few tests and I got a writing speed of around 4-5MB/s , however the reading speed (tested with freeware HD Tach) is peaking only at 8MB/s where with my old 8GB card I can get 30MB/s at peak.
The tests have been performed on my PC using the HD2 in mass storage mode.
Has anybody bought the same card from Play?
What speed do you get with your memory card (tested in the same way)?
Thanks
speeds sound about right on a mobile device, i am not sure how you managed to get 30MB on a mobile as that is like 'unreal' speeds. For a desktop bechmark that seems fair but not in a mobile.
I made a test with a different software and I get the same writing/reading speeds. Note that the 8GB card is class 4.
Unfortunately I cannot use a desktop card reader for benchmark as the one I have got it's very slow.
Hence the reason for asking other people to test their memory cards on their phone.
Thanks
Hi,
I am eyeing for the sandisk mobile ultra 32gb class 6. It claims to have 30mb/s read speed which is really impressive.
But does galaxy note sdcard reader will be able to handle 30mb/s read speed? Because for what I know most card reader tops at 20mb/s which is why most cards even those class10 ones has read speeds of less than 20mb/s.
Please correct me if I am wrong.
Thanks.
I don't think Note can handle 30 mb/s .. someone with more insight on the hardware of the card reader on Note might be able to help you
I have 32GB 10 class I can help but tell me pliz how to chech the speed read write?

That's the 'realism' that I had in my mind. If I have a full 32gb card, and wanted to transfer my pictures and videos, which is what mostly the card will be used up for, how is the transfer speed will be? If I am able to use the full 30mb/s read speed on sandisk mobile ultra card, that can greatly reduce the amount of time to move 32gb of data off the sdcard.
For sdcard application usage within the phone itself, the only thing that I can think of that will use alot of bandwidth on the card is recording full hd video, which a class 6 card is more than enough to handle the write speed. If for read speed, a mere class 2 cards can do 8mb/s read speed which is fast enough to watch your regular hd video, listen to your mp3 etc.
You just can just connect the phone to pc as storage mass and the program will detect the drive. You can start the test using the software.
What is your microsd brand?
k heres my 2 cents, my family has 5 galaxy notes. Basically I tried many brands ranging class 4, 6 and 10. First off the class 4 32g are like 40% or so slower than the class 10's. The 2 class 10's I have are all different brand both 32g and I can tell you they don't really make a lot of diff in terms of speed its less than 0.5mb per sec diff (the slower class 10 is same brand as the Note and the other one starts with Lex???). Then you have the class 6 64g which runs up to around 10% or so slower than the class 10. At the end of the day what you find is class 6 and 10 are both fast but the class 4 are dam slow. On my machine I'm using the 64g card. Speed was determined and optimized by SD booster and SD tools.
Thanks for info, that's alot of GNotes you got there.. your family must like BIG SCREENS.
Anyway, my actual question was, is the GNote be able to handle 30mb/s transfer for the sandisk mobile ultra versions or atleast what is the highest read speed for GNote card reader.
There is one benchmark that I came across somewhere that proves that the card does actually deliever that transfer speed albeit using usb 3.0 port. It takes atleast a regular usb 2.0 reader on a usb 3.0port to achieve it. A usb 2.0 reader on usb 2.0 port barely makes the 20mb/s mark on the same card. So the usb 3.0 port is quite crucial even though a usb 2.0 reader is being used on it.
So yah, the ideal situation is someone actually has the sandisk ultra mobile card + GNote and is willing to give spare time to benchmark it for us and post it here.
I got my wife a Moto X4 from Project Fi. She's excited to be able to dump an extensive music collection onto an SD card. We've been using Nexus devices for 5 years or so now, so we've never had to buy a micro SD card.
I assume this is going to work similar to how last year's Moto Z Play worked:
https://motorola-global-portal.custhelp.com/app/answers/indevice_detail/a_id/113319/p/30,6720,9835
I don't see any need to register the SD card as internal storage (which would replace the internal storage. 32 GBs seems more than adequate for apps and photos). So it seems likely that most of the mid range cards on amazon would be fine.
That said, the price drop on some of these cards since I looked last is kind of mind boggling. Both of these 128GB Samsung cards seems like it could function as an internal card if we choose:

https://www.amazon.com/dp/B073JYC4XM/ref=psdc_3015433011_t2_B0118LR9Z8
Anyone have any experience here that would be useful to know?
I always try to buy memory from the company who actually manufactures the chips, so Samsung and Sandisk are great companies to buy from.
I would also check out this one: https://www.amazon.com/Samsung-MicroSD-Adapter-MB-ME128GA-AM/dp/B06XWZWYVP. Much faster speeds, low price, and great reviews.
Here are the benchmarks for all 3 chips:
Brand: Samsung
Model: EVO+
Speed Class: U1
UHS: UHS-I
Write / Seq: 22.6
Read / Seq: 91.6
Read / But: 89.2
Write / Ran: 32.4
Rated Read: 80
Rated Write: 20
Brand: SanDisk
Model: Ultra
Speed Class: C10
UHS: UHS-I
Write / Seq: 23.6
Read / Seq: 91.3
Read / But: 90.2
Write / Ran: 27.1
Rated Read: 90
Rated Write: N/A
Brand: Samsung
Model: EVO Select (MB-ME128GA/AM)
Speed Class: U3
UHS: UHS-I
Write / Seq: 84.4
Read / Seq: 86.8
Read / But: 82.9
Write / Ran: 77.0
Rated Read: 100
Rated Write: 90
As you can see, the U3 chip is MUCH faster when writing. If you're copying a large music library, that's the difference between 20 minutes, and 80 minutes. Since it's the same price, go for the faster chip.
The only exception I could see a case being made is if you like the more "rugged" specs of the Evo+. Waterproof, shockproof, Xray-proof, etc. Although my personal opinion (which includes 3 years of data recovery on flash cards), I wouldn't bother. If you can insert the SD card into the phone without damaging it, you're all set. There is almost never any physical damage that happens to an sd card once it's inside a phone. Electrical damage is possible, but that will happen regardless of the card you're using.
Thanks for this, Just bought the Samsung Evo Select U3
Economical micro SD card
The Moto X⁴ manual only has two statements about the external storage:
"Tip: use a Class 10 microSD card for better user experience."
and
"Note: your phone supports microSD cards up to 2TB."
The second statement implies that the system is capable of using the SDXC Standard. So far, so good. The "Class 10" tip isn't telling us what the actual hardware is, i.e. whether or not it supports UHS-I, UHS-II, or USH-III bus speeds. (I suspect that it is limited to UHS-I due to something I saw on the Moto Z documentation.)
If we could get a definitive answer on this issue, it would be a relatively simple matter to translate the specifications to the product marketing designations. That way we wouldn't end up paying for hardware that goes unused and that might even cause the system to use sub-optimal fall back capabilities.
If you want to be as confused as I am on the matter, I suggest a visit to the SD Association website. (I can't link yet.)
Hello sorry for the necro but I just bought a Moto x4 and I’m looking to buy an sd card. Has anyone figured out what the max read/write speed of the phones sd slot is? There’s cards now advertising (up to) 300 MB/s read and write so I’m just wondering what my options are and the best way to spend my money. Thanks.
I ended up getting the SanDisk 64GB Ultra microSDXC UHS-I 100MB/s, C10, U1, Full HD, A1, SDSQUAR-064G-GN6MA and was satisfied.

Hello guyz,
Can you please recommend me the best microSD card for our phone in 128GB or 256GB?
I am leaning towards Samsung Pro Plus 128GB or EVO Plus 256GB. Should I go for speed or size?
Also there is Sandisk Extreme with similar speeds and Lexar Professional with read speeds @ 150mb/s, but I'm note sure if these speeds are overkill for a Note8..
I would also like to know cause eBay has so many fake ones.
I honestly have had issues with every sdhc I've used except for the EVO's. I don't know about other Samsung classes but I personally would stick with genuine Samsung memory cards.
Sent from my SM-G955U using XDA Free mobile app
I've been using the 256GB EVO that Samsung was giving out for the Note7 promo. Been working great.
I lost my $32 for useless SD card
I wouldn't worry too much about speed, as you can install apps on the SD card (correct me if I'm wrong). I would go for size over speed.
Never had issues with the Samsung or Sandisk memory cards for mobile devices, I have used everything from 2gb cards to 256gb cards and I will be looking at the 400gb card as soon as Sandisk gets it to retailers.
Samsung EVO Plus Grade 3, Class 10 128GB MicroSDXC thats one i have in my Note8 and as i don't shot lot of 4k videos that speed is enough
400gb for the win chuck
sandisk 400gb. Note8 ready. get it ONLY from "ships and sold by amazon". never 3rd party.

Fastest is probably:
Lexar Professional 1000x microSDXC (up to 256GB)
Biggest size is probably:
SanDisk Ultra 400GB microSDXC UHS-I
Best price/size/performance? Probably Samsung Evo+ line of cards, based on the following (it's a guess, I have not benchmarked them myself):
https://www.pidramble.com/wiki/benchmarks/microsd-cards
Do not rely on only the manufacturers' ratings, they can be way off and sometimes read is fast, but write is slow (or vice versa). The most expensive is not always the fastest either. Further, some excel in big sequantial reads, others are a tad better in random read/write IOPS. Even further, Note8 card interface probably is NOT able to use the maximum speed out of the latest UHS-II cards.
And yes, do NOT buy on eBay, unless you are willing to gamble or really know what you are doing.
My experience with SanDisk
Hi,
I just bough an Sandisk microSdhc Extreme 128 GB, Class 10, U3 UHS-2.
I emailed Samsung about my Note 8 and they told me that it supports UHS-2 cards.
When running tests on phone I get MAX 60write 60read
Only on DiskSeed Test App I got 287 MB/S read and 37 MB/S write.
Any input?
I've had my 64gb SD card in my s5 before putting it in my note 8. I might be lucky, but I figured Samsung cards work best in Samsung devices, idk. But yeah, it's been about 3 years and the SD card is going strong.
Andddddd...itll probably break after this post.
Galaxy Note 8 has many options for microSD Card for it. Here I found much different Note 8 Memory Card.
Never had an issue with any Sandisk microSDCard. I have had a bunch of them and they all work fine.
I'm another using the Samsung 256 EVO that came with the Note 7 promo. It also worked fine in an S7Edge for a while before I got the Note 8.

Anyone know where to get this one at a better deal? When it comes to device storage I'm not as much concerned with speed as I am with size and having 400GB at your fingertips, on the go, is just pretty freakin' awesome.
Btw...for those looking for more speed, I happened to catch this video on YouTube the other day that explains what the different speed markings on the sd cards actually mean if anyone's interested. I found it to be fairly informative.
Hello,
has anyone been able to figure what the sdcard ratings are on this?
is it UHS ii?
can anyone post their write speeds?( people with sd cards anything under UHS i/ v30 please dont bother posting)
edit:
Also, to unify results can everyone use Androbench app?
And be sure to go to settings and point your ext sd card.
thanks
ain't anyone interested/curious in how fast their transfer rate to their sd card is? gues because it has nothing to do with facebook or antisocial media then it doesn't count as being a real thing...
if you have Solid Explorer you can visually see your transfer speed.
transferring the same file across different phones / SD cards can give you a comparison.
i believe the bottleneck is the SD card, as the phone is capable of transferring at speeds far beyond what the SD card is capable of. so even if the Note 9 can transfer faster than the other phones, the SD card will limit it to a fraction of its capable speed.
check Notebookcheck.net
Also most of the phone is stuck at <100MB/s for SDcard transfer rate atm. I don't know why but, maybe to prevent heat generated.
You can get an UHS-II TypeC card reader ya know. or get 512GB for full UFS 2.1 speed.

No not really. Different files and sizes transfer at different speeds. Also, you're basically stuck with whatever speeds you get as there are very few ways to 'optimize' or 'tweak' performance of a SD card. And besides most people are still buying MP3s. Why? I don't know. Ain't anyone interested in listening to CD quality music? Myself, I still buy compact discs and rip them into FLACs and MP3s when I get it then the CD mostly collects dust.
And some of us are waiting on 512GB cards from Samsung and SanDisk to come out. No point in buying a 400GB card when I know I will get the 512 when the price comes down.
all this is fine and dandy but i was expecting actual file transfer read and write data numbers.
none provided their current rates. all other info is irrelevant.
thanks
I'd be interested to know the slot speed rating as well. Currently the phone defaults to using the internal capacity to write to for things like high-end video recording, due to the external SD not being fast enough.
...But is that actually due to the slot speed not being fast enough? Or because the vast majority of users will use standard SD Cards, which aren't fast enough to keep-up and it would cause complaints. Would be nice to find out it's the latter, I wouldn't mind investing in a faster SD Card for a little boost in performance.
Although I don't know the specifics for the Note 9. The SD card reading hardware on the device is the bottleneck and a source of where all manufactures go cheap. The read and right will top out between 60MB/s to 70 MB/s. This is why the internal storage is preferred but I the device for use and the main thing people overlook when it comes to devices with expandable memory. Expandable storage is simply meant for storage and not for high quality video recording and bust, super slow-mo, and other high quality video and image writing.

4k video takes about 100- 150Mbs on a high end camera. That's about 18 MB/sec write speed. All the medium/high quality sd cards can do those speeds...

Yes, but most cards don't reach their advertised potential and multiple simultanious writes impact speeds a lot more. This is why there are 512GB devices and why they still sell. The average person won't max out the capability of the SD slot but you always get a few that will use the device well beyond what most of us will.

I use a Samsung EVO Plus 128GB card. 68MB/s sustained read and 62MB/s sustained write, using a 28GB 4k Blu-Ray rip. The card can read 100MB/s and write 90MB/s but those speeds are only close to achievable when plugged into my USB 3 card reader.
It's rated at 100 gigawatts.

Yes, but it is a large file. Read and write speeds tend to start off a bit better and should be a bit better for smaller files.

no problem, tests are encouraging. i have the evo plus 256gb and and on the note 8 was getting barely 10 MB/s write speeds.
on the computer was getting the advertised speeds on an UHS 3 reader.

1st Run:
Read: 76.1mb/s
Write: 31.01mb/s
2nd Run:
