Best Micro SD Card for Note8 - Samsung Galaxy Note 8 Accessories

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.

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.

32GB microsd cards coming soon?

Since I've bought my Omnia II I've been looking forward to getting a 32GB microsd card which the device claims to support. Only problem is that they don't exist yet and I can't find any information on when I can expect them to be in the market, or how much i'll be expected to shell out for one.
Anyone else holding out for a 32GB card? 16GB is a lot, but not nearly enough to hold all my music, let alone having room left for taking photo's/videos.
hopefully in a few months ,according to this http://www.engadget.com/2010/01/13/samsung-announces-64gb-movinand-flash-32gb-microsd-card/
I wouldn't hold out for anything...

The new crop of microSD cards are getting ridiculous storage capacities for something this small - step back 16GB microSD cards, the 32GB cards are coming to town. SanDisk just might be the first to release microSD cards of this capacity.
By the way, this is the Swan song of microSDHC - they are capped at 32GB capacity. Coming to replace them will be the microSDXC variety (XC stands for "extended capacity").
Getting back on topic, SanDisk will release the world's first 32GB microSD cards next month and their price is expected to be 200 US dollars (150 euro), which obviously includes he early adopter's fee and the bragging rights that come with it.
We're joking of course, but 16GB microSD cards from SanDisk can be had for as low as 40 bucks - buying a phone with a hot-swappable card slot sounds like a good idea, doesn't it?
But if you absolutely must have one, you'd need 200 dollars by next month when these cards start shipping.
Source 200$?? LOL,,LET OBAMA PAY FOR EVERYONE OF THEM

Not all micro SD class 10 have the same speed my friend.
class 10 card means that meets the minimum requirements of class 10 of SD Card Association protype, which is 10 MB/second
in fact some quality class 6 cards may give you speed more than 10 MB/s, while cheap - low quality class 10 will give you just 10 MB/s or even worse theoretically 10MB/s under perfect weather ect condintions.....
par example samsung sd class 10 plus gives you up to these
• Speed Rating Speed (read) : 24MB/s
• Speed (write) : 21MB/s
which i think worth the few extra usd.
same brand's class 6 cards give you
Speed (Read) 17MB / sec.
Speed (Write) 12 ~ 13MB / sec.
which is much faster than low quality class 10
So you should rethink about class 10 now
Yeah i agree.
My Class 6 Sandisk transfers at 10MB/s beating my Class 6 32GB Gskill transferring at 6 MB/s max.

Recommendations for micro sd

My 16 gig kingston filled up quite rapidly after 2 weeks so I'm looking in getting a 32 or 64 micro sd but not sure what I shall get.
I see theres sdhc sdxc but not sure whats the differences.
I read theres issues with sandisk so I was thinking of either samsung lexar or kingston.
Also does the note 2 use the class 10 cards to its fullest as in its max read/write speeds?
I've read its pointless paying extra for the class 10 cards since the note2 dont use it to the fullest
Thanks in advance for any replies

either buy 32gb or 64gb any company OTHER THAN SCANDISK ............................it Sucks big time. i have scandisk 32gb and it keeps on unmounting mounting every now and than .
sandisk 64gb class 10
The Note II can use a 64 gb sdcard. I would only use a class 10. Its way quicker tranferring files, or taking videos. Also you can use SD-Booster. Download from the Play Store. Its free. You can tell the sdcard at what speed to be ruiing at. 2048, 4096, etc, etc. Phone must be rooted to use.

I have and currently use the ScanDisk Extreme 64GB SDXC class 10 card. I haven't had, or at least noticed, any issues while using it. I just formatted the card right away when I installed in the phone.
You may want to install directorybind. I believe you need root. A lot of app install on the phone's storage, not on the SDcard. So you may want to check if your card or phone storage filled up. Other than that, I would suggest moving pictures and videos off your phone if you have a lot.

If you use a swap file on the SD card, it will go bad way faster than normal. I avoid using the card for a swap file.

Lexar
I've been using a Lexar 32GB Class 10 Micro SDHC card for many months. Both in the Note 2 and previously to that in an S3 -- no issues ever. No crashes, no unmounts, no corruption, etc.
I got mine when amazon had them for $40. I got two. One is in a tablet, no issues. The one in the GN2, I originally put in my Evo 4G and it worked fine; it couldn't get class 10 speed, but worked very well with Boot Manager
Thanks for all the replies
I just bought a kingston 64gb sdxc class 10 earlier @ frys for $40 after tax.
They have a sale expire tonite it was just a weekend sale and I was lucky to grab the last 1
Got it install and man this card is quick much better than my old class 4 lol

Get a Samsung branded one to avoid the mounting and unmounting problems. Ivd go that route when my 32gb dies.

SD cards?

Should I go with a Samsung card for my 8.0 or is ok to use other makers cards, specifically talking about the ultra, extreme types. I want something fast but compatible.
Thanks in advance!

I have been looking for a 64g SD card for my samsung tab 3 7". After reading many reviews on amazon I have discoverd a few things you might want to consider.
1. Anything over 32 gig is a whole different world for sd cards an compatibility especially for Samsung tab 3's
2. I don't know about other brands but sandisk seems to have formatting problems with android. They sell several different 64gig cards and some come with a warning that reformatting in the mobile device will leave the card unusable.
2. There are a lot of counterfeit 64gig cards out there and even though people are complaining about it, Amazon continues to sell them. Read the reviews carefully.
3. I don't know if the tab3 can utilize the class 10 cards that claim 30 mb per second.
I just started looking into getting a 64gig card for my tab 3 and my information is still incomplete as to what to get. All I can suggest is read, read read... There are some shifty deals out there.
I hope someone that has more knowledge about this subject will chime in as I am somewhat confused about the best card to go with.
Copy that. Thank you very much or the input, I was also just reading about the counterfeit cards that Amazon is selling in the reviews for some cards and elsewhere. I'm not sure why or how they would continue to sell them knowing that they are fake! I am seriously thinking about just going with one of the nicer Samsung cards and be done with it.

I'm using one on my tab 3 right now, it's only 8gb though but. But the read speed is 24~30mb , write speed is 10~12 mb/s.

it's ok to use other SD cards
but if you want the fastest, always buy an SDHC or i can say a class 10 SD card
anybrand seems fine like sandisk, patriot, kingmax, etc.
but now i'm using patriot 32gb LX class 10, works fine
32gb class 10 confirmation

Cool, Good info. Thanks
Just to update its been 2 weeks now and the cards are doing great. I read the reviews before I bought and they said the transcend was very compatible with devices and since samsung is so picky I liked hearing that. Also a lifetime warranty is great too. Proof of purchase is necessary but since I purchased thru amazon I always have a record.

SD Cards - Samsung Evo Plus Vs Sandisk Ultra

Have got a couple of HD8 2017 tablets and installed a couple of Samsung Evo Plus 64GB MicroSD Cards. Been having some difficulty with these cards in at least one of the tablets so awaiting delivery of 2 x SanDisk Ultra 64GB cards to see if I get on any better results. My question is which card is better for tablet use?
Samsung Evo Plus, 64GB, Class 10, U3
Sandisk Ultra. 64GB, Clas 10, U1 - A1 App Performance
On first look I assumed the Samsung as it was U3 rated compared to the SanDisk U1 rating, however the SanDisk card has the new A1 App performance rating. Does the A1 rating therefore trump the Samsung U3 rating or is this really marketing over reality.. Also, in real world use is the difference between U3 and U1 negligible when using the card for tablet use?
Thanks in advance

Don't confuse raw speed on large files with stability, ability to efficiently handle multiple small IO operations and suitability to the task at hand. Not to mention device characteristics and capabilities of the external storage interface. Fire 7s have a mediocre SD card interface; suspect the same holds for all 5th-7th gen models which are budget friendly.
Personally I have not had good luck with Samsung EVO branded cards. I use a variety of other cards, including SanDisk, which generally live up to their stated capabilities. For whatever reason the EVOs fall short. Reviews on Amazon and elsewhere suggest I'm not alone in this observation.

Interesting. In both my Fire HD8's, using the Samsung Evo Plus cards, I've had multiple "SD Card Unexpectedly Removed" warnings which is a pain in itself but also causes freezes and sometime complete lock outs. Just taken delivery of the SanDisk Ultra 64GB U1 A1 cards and popped them in and, so far, seem more stable. Still early days but let's to see if these work better than the Samsung Evo Plus cards.

hi brother, i have same thought to buy either this 2 card as its same price.
Hows your review so far? normally i use sandisk, i nvr try samsung before..

MicroSD card tests. Which is the fastest to buy? Need your help

So I just bought this card to replace the old 128 I had in my note. Little frustrated cause it's not much faster than my old one. They advertise 90 to 100 read and write speeds. But it doesn't even get close to that. What's your opinion on these cards and post pics of the speed of your cards and what model card you have. Please use the app I used so I can compare.

@borijess I'm on vacation to a remote location and don't have the app you used to test but prior to my vacation I used SD Card Test Pro app and here are the results I got with a recently purchased SanDisk Extreme PRO microSDXC 128GB Memory Card, Class 10, U3, V30, A1, Read 100, Write 90.
Using SD Card Test Pro I got the following results: Read at 91.9 and Write at 84.4. Ran several tests over a period of 3 days and the readings were always very similar to what I just listed. I was never able to reach the read 100 or write 90 that SanDisk rates it at. But, I'm happy with the read/write speeds that this card gets. I quit using Samsung SD cards a while back as, for me anyway, I found that SanDisk just performed much better in my Nikon D810 camera, my GoPros and Samsung smartphones.
When I get back from my remote trip I'll try your app and post results.
