What brand are you using? Not all microSD cards are equal. Especially, since there are several knock offs on Amazon. I have a Samsung 512GB EVO microSD card in mine and I don't encounter any speed problems.

Could you test with this app?
A1 SD Bench - Apps on Google Play
Benchmark SD card to test IO read / write speed and check media performance.

I'm getting about the same. Did you encrypt your card? Mine is encrypted.
Encryption slows read/write speeds because it has to decrypt/encrypt when reading or writing.
I don't see any real world affects on performance.

How big are the files? How are you transferring them? Via USB from Mac/PC to the card in the tablet? Or from internal memory to the card?
If the former, your read/write speeds are going to be slower because you have to take into account the limitations of the USB cable and the bus speed from the USB ports on your computer and the bus speeds from the USB port to the card. Each transfer point is a place where it will slow down. If it is the latter, then your limited by the bus speed between internal memory and the card.
In either case, you will probably never reach the full read/write speed potential of the card. Even if you were to use a faster card, it won't improve your speeds all that much.
Internal memory to sd card or via usb or via otg doesn't matter.

Sorry for the slow response. In both cases you are subject to the internal bus limitations as well as card limitations.
Think of it as flying from New York to LA with a stop in Dallas. All three airports are big and the planes are fast, but in all three cases you are slowed down. You have to wait in line to get through security and get on the plane, then wait to take off, then wait for the plane to get to its gate in Dallas, etc. Each point is a bottleneck.
The point being is that anytime you have to transfer from one medium to another the transfer point will be the bottleneck. There isn't much that you can do to speed it up. Getting an even faster microSD card will not improve your performance by much.

Yes, I did. You are comparing three DIFFERENT devices with three DIFFERENT bus architectures. Comparing your Windows notebook, Poco X2 Pro and Tab S7 is not an apple to apple to apple comparison. It is an apple to banana to orange comparison.
I got the same read/write speeds you did on my Tab S7. If I were to clock it on my Surface Pro 6 or Dell desktop, I would probably get similar speeds as you did on your Windows notebook. The bus speed of the Tab S7 is the culprit and getting a faster card will give you a negligible increase.

Yep different devices but Poco's(Xxiaomi) medicore device three times faster than Samsung's high level device. Is this normal?
i just discovered if i eject micro sd card from tab s7 and than plug again. Than I tested micro sd card. Speed similar to Poco X3 pro. But some time later (about hours) micro sd card speed slowing down.

Yeah. That is weird. I could be the OS deprioritizing the microSD reader to save battery. But that is just a guess. As far as the differences between the Poco S2 and the Tab S7, one is a phone the other a tablet; both have different use case scenarios which drives the different design philosophies, which drives the actual design and component selection.

man that's crazy, although the 64's won't work with g1, I think its expandable capacity is only 32gb, but that's still big! Not sure of the class #'s on these bad boys, but I'm sure if there aren't any 6 or 10 class versions available yet it won't be long!
EDIT: nevermind, they're all 32's.....the 64gb has something to do with flash or whatever, IDK
32gb is the addressable limit of the SDHC standard.. when 64gb cards appear they will be SDXC, which means no current hardware can use them. Awesome.

Strange you should say that....

As I'm a newbie, I can't post external links.... but apparently CAN post links where "http" have been changed to "hxxp". I spotted this link earlier today, from Morgan Computers - a BIG hardware-clearance company in New Oxford Street, London. £51 for a 32Gig SDHC card.
" The 32GB SDHC memory card is German made, leading edge technology at its best! It also comes with a lifetime manufacturer warranty.
The 32GB SD Card offers high storage capacity with a write speed of 10MBytes/s and a read speed of 20MBytes/s. It is ideal for new generation digital camera and other applications with SDHC cards slots.
Compatible with All SDHC devices
32GB stores approx 1200 x 10MP Photos, 545 Hours of MP3
May be in Eco Friendly Bulk Packaging
*Please Note: SDHC cards will only work in devices that are compatible with the Higher SDHC Specification cards"
I'm going to invest in one of these for my (new!) Desire - my two G-1's will have to continue to make-do with 8 Gig Sandisk TF cards.
You let us all know how that works.

I have two 32GB SDHC's, one is class 2, the other class 6.
The class 2 works but it's insanely slow and it consumes a lot of battery due to the extra hot time required for reads and writes.
The class 6 is extremely fast and doesn't cause noticeable battery drain.
So am I correct in assuming that the higher the class number, the faster the performance & lower the power usage?

Meh. Until there's a PAE firmware released for the device. Like how a 32bit OS can only handle 4GB RAM until you enable PAE. (In windows, you can simply "turn it on", in linux you need a kernel with a PAE module enabled)
PAE, or Physical Address Extension, should allow for a 52 bit limit on physical memory but only supports a 48-bit virtual address space. 4 × 10245 bytes, or 4 Petabytes and 256 × 10244 bytes or 256 Terabytes, respectively. (What that means is, if the hardware doesn't support 52 bit addresses natively, then they highest capacity that can be reached via PAE is 256 Terabytes through virtualization.)
What does that mean for an android device? A PAE Kernel Module could be created to allow for addressing of more than 32 Gigabytes, how far past 32 Gigabytes? That I don't know. I would assume at least somewhere in the realm of 128-256 Gigabytes. I doubt there will ever be a MicroSD card at that capacity though. By the time we see affordable solid-state storage as small as MicroSD with a capacity over 64 Gigabytes it is unlikely that MicroSD will even still be around, and I doubt anyone will still be using the G1 anyway at that point. We're talking another 4 years or so, making the G1 an antique by technology standards.
tl;dr version: Once 64GB cards are affordable enough for it to be practical to put the time and effort into a firmware mod (kernel module,etc) for an android version of something resembling PAE, you can expect -someone- will figure out a way to enable 64GB usage in the G1.
I think we're gonna see faces like this: all the time, when it comes to electronics industry... I can still remember my first Intel 486 with a few MB HDD!
Man one of these would be nice!
For me 6gb is enough..
For music etc i have a mp3 player!
Here we are 2 years later, 256gb micro sd cards are just starting to appear on evilbay.
Also USB thumbdrives that can handle up to 512gb cards

Why did you need so much space???
Sent from my SGH-M919 using xda app-developers app
Over the years I've owned about every brand of cards from eBay cheapo's to the best the industry has to offer like Samsung. I shoot HD wedding videos, take millions of pictures and edit so micro SD cards have been a necessity.
It just dawned on me today when I was looking at the mountain of SD cards I have in my office and realizing the life span on all the cards I've used over the years. Therefore, I'd like to share my experience along with asking those who are knowledgeable in the area of memory cards to help answer some of my questions.
I shoot HD videos and take lots of pictures on my Note 3 so having a reliable card is very important to me. Currently I'm locked and loaded with a 64GB | Class 10 | SanDisk microSDXC UHS-I card in my Note 3. (I also have a Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM), which I use in my Canon Video Camera and it is by far the best card out there. Period.)
The 6 most reliable cards that I've owned throughout the years: (Best to Worst)
Samsung
A-Data (Samsung chip, go figure. However, they are highly likely Samsungs '2nd hand' chips as they are not as fast as the actual Samsung brand labeled chips.)
PNY
SanDisk
Kingston / Sony (tie)
Transcend
It's not worth listing the other non-brand ebay junk so I've left those out.
Lately, I've been very disappointed with SanDisk's quality. Especially with their Class 10 cards, where I have found them to have a very weak 'integrity' in their chips. A good card should give you about a million write cycles. (Write cycles is a whole another can of worms...)
I have had more failed SanDisk's (lemons) cards than any other brands combined. This is why I will never buy SanDisk again and am switching to what has never failed me, Samsung. I can't afford the chaos and hate having to recover priceless wedding pictures from a card who decides to kick the bucket when you need it the most.
Recently my 64GB | Class 10 | SanDisk in my Note 3 decided to go belly up and I had to use a data recovering software to salvage all my 4,000 pictures and hundreds of HD video's. WTH right? This card is a couple months old. My previous SanDisk in my old Note 2 did the same thing after a couple of months.
ME, MYSELF AND MICRO SD CARDS...
With a new card I reformat it to Fat32 with Disk Utility (Mac) and then pop it in my device.
Since I take a lot of pictures / videos, I connect my phone to my computer (Android File Transfer, works flawlessly on Mac), copy over everything to my hard drive, back it up again if it's important and then properly eject the phone/card. I've always read and heard from camera guru's that it's best to reformat your card from the device instead of deleting the pictures in the folder from your computer while it's still connected. Therefore, after copying over the pictures/videos I would immediately eject and delete directly from the phone. The 'theory' surrounding this is that if you leave your card connected to your computer, it will access (checking byte order/changes) the directory more times than you would want it to thereby decreasing the life expectancy of the card.
Now of course it's not convenient or practical by no means to do this every day with your Note 3...most people just plug in and play with no problems whatsoever throughout the life of the card.
QUESTIONS FOR THE GEEKS
Explain the difference in the structural integrity of the internal SD card vs external SD card.
How much more life expectancy / write cycles does the internal card have vs an external card?
For a heavy user like me I have always put everything on the external card to avoid using the internal memory as much as possible avoiding unnecessary stress.
How often should the external card be reformatted for a heavy user like me where I'm constantly copying over, deleting, etc...
To be continued...
I don’t know about card in deep technically but all I learned so far, generally cards these days have very long life span, at least average 10 years, unless physically damaged or any uncommon technical issues.
I too concerned about this too earlier but now technology is so fast upgrading you shouldn’t worry about its life span. Technically what I know its life span also depends on it read and writings like you said and even if your car had heavy use then there is no point to formatting it frequently. Card is not like windows which creates junk files by time. Deleting and formatting does the same thing and both will free up same space if you delete all, where formatting read or write more data than deleting. So formatting frequently could reduce its life but that could be unnoticeable. The same way defragmenting, shredding also reduces its life. But shredding is good if I lost it any other couldn’t restores any private files.
So I think there have no logic to format it frequently to keep it healthy, unless its corrupted.
By technology is so fast upgrading what I mean is like, few years back I brought a new phone and brought the best card at that time, it was Samsung 32GB class 6. It was best on the market during that time. But then class 10, pro, plus released. Then when I got note 3 I had already a 32 GB card but I brought a class 10 pro one due to the HD recording. So after 5 years from now even if this card is working I will still have to buy a new one, as there will be far better technically upgraded one. I hope I make sense.
And I too use Internal memory very less, as loads on internal memory make the phone slower.
Thanks for the reply. I agree that with a decent name brand of a card, the life expectancy shouldn't be too much of a worry. My experience with SanDisk has been pretty poor in that I don't think they make cards with good quality material. As mentioned, the structural integrity is very weak. Their older cards were better. The newer ones in my opinion and from my experience have to be treated with a mentality of 5 years ago, because they do wear noticeably.

I know that feel of losing data, I have had 3 64 GB SanDisk cards die since January - right now I am using a 8GB. sad n true
Wow, sorry to hear. That sucks. Then again, you've verified my point even further about how crappy SanDisk cards have become.
Let your next card be a Samsung. I'm weeding out my stock of cards, heck I've given some away already.
Here's the best: Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM)
I use it in my Canon and it's extremely fast.

I never used any SanDisk card on phone, only Samsung cards so I’ve no personal experience and I’ve seen many user complains about its compatibility and issues on Samsung device. However I’ve been using a SanDisk high-speed MMC card on my Nikon SLR over last 5 years and still its performing great.
I believe Samsung cards works great in Samsung devices. So far only one card got damaged many years back and that was a stock Nokia card.
I currently have a 64gb sandisk class 10 in my phone I always used sandisk and never had a issue. I can't say the same for kingston. I found out it doesn't mess up when you unmount it when taking it out. I never did that before and they got messed up even if it did get messed up warranty is always there.
currently using the sandisk extreme plus 64gb card with no issues whatsoever. will update this thread once it crap out on me (it probably will in about 6 months) and how the warranty process goes.
I had a 32Gb Sandisk Extreme die in my Galaxy Note 3 while recording 4k video on to it.
Without a compatibility list and guarantee from Samsung, I am reluctant to buy another high end microsd card.
I am sick of these SD Cards. In my Galaxy S3, the thing would ocassionally take a dump and have to be reformatted.
Now I just restarted the Note 3, and boom, card took a dump.
I think I'm going to just live without.
Sandisk has always been reliable for me, apparently there are only 4-5 chip manufacture, and majority of a-data's card are rebadged from sandisk, same goes with transcends, whiles kingston are with toshiba, and PNY is a mix of sandisk and toshiba.
For data recovery and/or SD card repair, had anyone given Spin Rite a try?
I've been using a UHS-I 16GB Team card in my phone, been pretty reliable so far and gets pretty quick read/write speeds. Also been using a 32GB UHS-I Samsung card in my Sony NEX-5T camera, also been having no issues.
Just had my first Warranty experience with SanDisk. My 64 Gig SanDisk Ultra had crapped out by not allowing any write cycle this would not allow for deleting files or format or any changes to card. After a brief chat session on the SanDisk website I had my RMA and got emailed a label to print. My old card was off to SanDisk. 10 days later the new card arrived. This was a good warranty experience. Hope the new card will have more writes.

I'm glad I'm not alone on this. I have my first 64GB microSD on Jan last year. I chose Sandisk because I believe many of tech experts favor them over every other brand. At the time I wasn't at all concerned about its lifespan because I am using it for such a simple task like music storage. By the end of Dec last year, the card refuses to write and format. Folks at Sandisk forum suggested to use SDFormatter, however if you get "write protected" error, your card is not repairable, they say.
I was lucky to get a new one so close to the end of my one-year warranty. But seeing Sandisk cards are getting less reliable these days, I might give Samsung a try if my Sandisk fails again.
Quick question, though: where else does Samsung evo and pro differs beside speed? Does pro have longer lifespan?
Interesting. I've been using Sandisk for well over 10 years in everything from my DSLRs to my phones, never had a single card die on me.
I have owned 3 64GB Samsung MicroSD's over 2014 and they all died within two months.

Lifespan? Didn't know they were supposed to "die", or even wear out, and stop working eventually. Been using this same SD card for the past 2 years, and works like the first day I got it.
Hi,
It seems a lot of people go for micro sd cards (such as class 10) for additional external memory with otg adapters
but I thought usb 3 is much faster and cheaper?
can someone clear this up as I could not find the answer .
anyone know which offers the best speed for saving pictures onto it and playing a couple of emulator games from?
The problem is that the samsung is using usb 2.0 which means the maximum speed that you will achive is about 25-28(MB/s <-correct me if I ma not). If you writing using computer that has a usb3 you will see the avantage of faster speed otherwise there is not. Futhermore good qulity pen drive are faster than a sd-cards class 10 becasue it this type of card only provide 10mbps speed for writing which is good for most part unless you playing 4k video. I would suggest going for UHS 3 type of cards which will saturate usb2.0. that is 30MB/s. Any faster sd cards will be cap by the usb controler. Futhermore memory cards are smaller, ligher and more reliable as a storage because you can easly damage flash drive whereas the otg will cost you couple of bugs.

The problem is that the samsung is using usb 2.0 which means the maximum speed that you will achive is about 25-28(MB/s <-correct me if I ma not). If you writing using computer that has a usb3 you will see the avantage of faster speed otherwise there is not. Futhermore good qulity pen drive are faster than a sd-cards class 10 becasue it this type of card only provide 10mbps speed for writing which is good for most part unless you playing 4k video. I would suggest going for UHS 3 type of cards which will saturate usb2.0. that is 30MB/s. Any faster sd cards will be cap by the usb controler.

Thank you for clearing that up, I could not find the complete answer in one single post so hopefully that will help others. You have a good point about safer storage as well.
A very cost effective 128GB UHS 3 card is something like the Transcend 128GB Ultimate SDXC UHS Ultra High Speed Class 3 Memory Card (SD and not micro SD
http://www.amazon.co.uk/Transcend-1...S-3+Flash+Memory+Card+95/60+MB/s+(TS128GSDU3)
The Micro SD versions are a bit too pricey so I might opt for a UHS1 instead
I am leaning towards micro SD in case I upgrade to a compatible phone, thus not need an otg adapter (note 5 or even the lg g4 pro which looks very promising indeed)
In light of what you said I am not considering the usb flash drive anymore so thank you for help and clearing things up
Many Thanks :good:
PS So With the next generation usb C, we get faster transfers with the next generation of memory cards or even existing ones we buy today? I'm wondering if it is worth holding on before buying.
Everyone buy this you be good

So I am switching from iPhone to S8 and I am looking for SD cards to buy. The last one I bought was Class 10 (U1) like 8 years ago. It appears there are some new standards which go upto UHS-III and boast solid speeds (U3). However, it also looks like they are aimed at video recording (GoPro/dones) use.
Do any of these advanced cards (U3) offer significant speed improvement in a smartphone like Galaxy S8 or should I just stick to U1?
What do you plan on putting on the sdcard? With my samsung evo+ card 80read/20write the gallery thumbnail loading speeds are dog slow. If you're just going to put miscellaneous stuff any card will do, 64gb of storage should be enough.
Damn thats slow... I do plan to use it for occasionally transferring movies, etc. but I am just not a fan of lags/slow loading like in your case which is why I was considering the advanced one. But if that's the general case then I guess an upgrade might be worth it :/
Thumbnail loading isnt really a factor of the memory card.. My Note 5 some gallery thumbnails NEVER load, and most others take a while, and thats all from internal storage. EVO+ cards in phones are generally great and shouldnt give any noticeable lag on top of any lag the phone/app itself shows. The biggest thing youll notice between cards is, obviously, transfer rates. If you will be copying data to/from the phone from/to another device, a good quality high-speed card makes a world of difference. anything with a real 80MB/s read speed will be fine, just make sure you arent getting a clone, so doublecheck who the seller is if ordering from Amazon, and to be safe DO NOT order from eBay.

For movies you should be fine, for me its loading a 1000 thumbnails that's the slow part, once they're loaded everything is fine. But from time to time it has to reload the thumbnails and its somewhat annoying.
There is an article somwhere floating around from last week on what cards to use etc.
If you use for photos and 4k vid etc the faster the better basically.
I think the more relevant question/answer here is whether the phones will support UHS-II and UHS-III. A few people have been asking that and I have not yet seen an answer. Since II and III have an extra set of pins, I would imagine it requires the host device to specifically support it by being able to use those extra pins. *If* they are backwards compatible (I don't know), then the cards might work anyway but would work at slow speed if the device doesn't support II or III and be a waste of money (obviously if not backwards compatible then it wouldnt work at all).
I still haven't seen an answer yet and as always samsung's specs dont tell you anything. We probably need someone with one of the faster cards and an S8 to try it out with A1 benchmark and see what speeds they get.
I don't think it supports UHS II or 3. I read somewhere that it supports UFS, which is Samsung's own higher speed format, which I don't think is as backwards compatible.
UHS I cards also have their own speed classes, U1 and U3 currently I think. U3 just guarantees higher sustained write speed (30MBps,) which is well within the UHS I maximum transfer speed.
If you're confused, the UHS class is the interface speed. The U1 or U3 are the minimum speed of the specific card. UHS I max speed is a little over 100MBps iirc.
I'm looking for either a 128gb or 256gb micro sd card and I want to have the same experience as using the internal storage for recording 4k/superslowmo and using apps on sd cards.
But I don't want to overspend either, I don't know up to what speeds/classes the phone can utilize.
There's cards like Samsung evo plus 128gb for 60euro, cards like lexar 1000x 128gb at 95 euro with UHS II Bus all kinds of things I got lost in the sea of classes and speeds.
What cards did you guys get and can anyone recommend me something?
I use sandisk ultra 200 gb and no problem @all with 4k
I got a samsung evo select 128gb and it is pretty damn snappy.

I use that also.. I think... https://www.amazon.com/gp/product/B01CO48M36/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Up to 95MB/s Read and 90MB/s Write speed with Class 10 and U3 compatibility
that was the fastest card available when I bought it, nothing was faster with high storage. I see 256gb cards now but haven't really looked into any or the specs
I got Samsung Evo+ 128 GB UHS-I U3 (100 MB/s read, 90 MB/s write) for 55 euros (just google MB-MC128GA/EU - NL Samsung site for this card) . There is also 128 GB Adata Premier One UHS-II with read 275 MB/s, write 155 MB/s for ~150 USD. 256 GB version is for 289 USD (amazon) - dunno why, but in Czech it is for ~210$ ^^. In your case, I would go for Samsung
Got the Samsung one now

I'd recommend the SanDisk Ultra 200 GB MicroSDXC UHS-I Memory Card as a good balance between capability, capacity and cost.

Sony 128GB UHS-I Class 10 SDXC
I purchased Sony 128GB UHS-I Class 10 SDXC Memory Card (SR-G1UY3A). Performance is simply awesome. It cost me Rs 5k.
I'm disappointed with XZP's sdcard access speeds, especially when the sdcard encryption is enabled. With my Samsung Evo+ 256Gb I got the following speeds:
About 7Mb/s read/write (with enabled encryption)
And about 70/40Mb/s (read/write) with disabled encryption.
What real speeds have you got?

Is this still a problem? I prefer to always have my stuff encrypted and had this same issue, so slow it's almost unusable. Wondering if any of the updates or anything have fixed this issue or not.

Yes, it's still a problem in Oreo. I have up to 10mb/s with enabled encryption.

Have you tried any other micro SDs or just the Samsung Evo+? I was thinking about getting the 2017 one, Samsung Evo Plus 256GB, but it seems like it will probably be the same, I think the only difference between that 2016 version is 10MB/s on Read speed. Would be interesting to see if certain cards do better than others, I would like to know if a A1 rated card also has this problem.
Hey guys. Thanks for all the helpful input. What would you say is the primary benefit of the additional storage of a 128GB to 256GB SD Card? I feel like on other phones without expandable memory, I never really reach capacity on 64GB models. So I probably used more cloud storage out of necessity and just got used to it. What are you guys using all this glorious storage for?

4k por... Oops I mean scientific ebooks etc.
All jokes aside... Having that bit of extra storage can give you the freedom to record, capture and download as you please!
Especially for people like me who hardly use online storage. I have the Samsung Evo Plus 256gb (2017 version) and I have so many 4k HDR10 movies and documentaries stored on it. I also dont have to worry about running out of space by constantly shooting 4k videos.
Having higher storage takes away all the limitations of having to transfer your files whenever you need to download new material.
I'm getting 72mb/read and 40mb/write even though the Micro SD card is capable of achieving higher speeds. This is due to the phone and I hope that android will find a way around this with upcoming updates, unless it's a hardware issue of course.
These speeds are more than enough for regular everyday use as I haven't faced any issues with reading/writing colossal files.
Hope this helps

You had me at 4k por... LOL. But seriously, I have never even seen 4K video let alone shot in 4K, so I am looking forward to checking it out on this glorious screen. Still think I may only opt for 200GB unless I find a really good deal (I will check the model you listed above). Doubt I will be able to even fill that but who knows. LOL. Thanks again.

Yes that is correct. My internal storage is encrypted and the micro sd card isn't.

Hey guys. Can someone please give me their thoughts on the MicroSD card linked below? Thinking of buying but not sure I need 256GB and the price is pretty reasonable on this 200GB. Thoughts?
