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.

Just got NC for early Father's Day! I luv ma fam!
Everything I been finding here talks about 2,4, or 8 gigs SD cards.
NC says it can use up to 32gig.
Anyone tried this? I figure SDHC 32 G class 6 would work.

Everything I've read states the higher capacity cards don't do well running ROMs. Like you I'm new to the nook so I"m sure someone else with more experience will chime in.
I have a 32 gig card installed right now. Works just fine as a data card.
If you want to run custom ROMS off the card, make sure its a sandisk. That flapping sound about larger sized card being bad for Roms is a buncha crap in my opinion (and I have the benchmarks on this card to prove it), but the BRAND of card makes a huge difference when running Roms. Avoid transcend and PNY like the plague.
That said, if you just want the card for data, then yes, the NC can handle them just fine.

What size Sandisk card do you recommend for running custom ROMs? I've read 8 but I really would like to run a 16.
With a sandisk, I can't see any reason why a 16 or even 32 gig card would give you trouble on roms.
Using the card to run your "operating system" seems to require a higher small-block read/write speed than most cards have. Two things seem to affect it: 1) brand (sandisk is currently the only way to go), and 2)it seems that higher classed cards sacrifice the small block performance a bit. This makes sense to me, since the classification related to large block sequential read/writes (iirc), so some trade-iffs are always expected.
See this thread for useful things.
And I think most people are buying the smaller card mostly because of price, and partly due to a herd mentality on threads like the above.
Sandisk 16gb is just fine for running the Rom off the sd card; that is my current setup.

I was referring to the specific instance of using transcend for running cm7 for example. I understand transcend and patriot are decent when used for data, and I have PNY cards in our cameras, so they seem to work fine for data.
I have a wintec SDCH 16g class 4 and it works fine, but I only use it for data.
I've been looking into this, and here's what it boils down to:
Most MicroSD cards are set up for data transfer aimed at large files, such as video or high resolution pictures. The majority of the market these cards are manufactured for are digital camcorders, cameras, and smart phones with cameras.
They've gotten great at streaming media to and from the cards, and using them as storage mediums.
Running an operating system from the card requires a whole lot of small data transfers, which is not a specification that manufacterers pay much attention to. Most people would never notice improvement in this area of the manufacturing process, so the companies don't waste money on it.
Different manufacturers have different ideas of what their product should be capable of.
SanDisk is the brand that has consistently tested better for small data transfer then other card makers.
Running programs/operating systems from a MicroSD card is a new animal, something that hasn't really been done before now, and the tablet market is still in it's infancy.
I'm sure this issue will be addressed by the hardware makers of memory cards over the next year or so, but for now we are stuck with the task of trying to figure out what works for our purpose given what's available on the market right now.
All this being said, out of a handful of cards I own, my 16 gig SanDisk class 2 MicroSD card is my highest performing card - more then twice as fast as even 4 out of 5 of the 8 gig SanDisk cards I have.
Here is the link to the software we are using to test the cards: Crystal Disk Mark
Post 5 in this thread has a link that takes you to the one that has become our communal benchmark thread, and has a lot of info on this topic.
I would surmise that a 32 gig SanDisk brand card would probably be pretty good given that:
-Sandisk 8 gig cards (in class 2 and 4) are the general recommendation
-SanDisk 16 gig cards consistently test to a higher performance level then the 8 gig cards.
If this is the beginning of a pattern, and the larger capacity SanDisk cards are inherently manufactered to a higher small data standard, then theoretically the 32 gig card would be better.
But, this is only a theory. A 32 gig card is more then just a couple of bucks, and I don't think we have enough benchmarks on them yet to say one way or another.
Even with the SanDisk 8 gig cards, there is a wide range of what you could end up with on small data transfer speed. It's kind of pot luck. Even the slowest ones are many orders of magnitude faster then most other manufacturers, though.
This would be a good thread for people who do have 32 gig cards of any brand to chime in on, so we could keep the discussion about the largest supported capacity card on the Nook seperate from the other threads on this topic.
I saw a thread a week or so ago regarding testing class 4 cards and which were better. I just ordered a NC the other day. Anyone know the thread?

You might mean my thread on comparing speed results between different readers using the benchmark software.
It's more a look at the testing software and methods of doing so then the actual cards themselves.
The more people who post benchmark results in the thread skwalas linked to back in post 5, the better of an idea we'll have of what works for us.
The amount of information we've collected so far in such a short time is astonishing - this is a great community.

Sandisk 16gb, Class 4; Got it from Radio Shack a month or so ago on sale for like $25.
32 Gig

Bought this one about a month ago. Transferred my 16G class 2 from Radio Shack to the 32G then expanded the partition. I run CM7 off the SD. Works GREAT!. I run movies, apps from the card with tons of room.
Thanks for all the replies! They been very helpful!

IIRC, Lexar splits their Class X cards into two more classifications, a regular and an Ultra class. Which one was yours?
Also, Radio Shack currently has 8gb Sandisk C4 cards for sale at 14.99. Perfect for playing with an SD install. With Crystal mark and a cheapie USB reader I got 2.5mb/s read, 1.5 mb/s write (both of the small block ones). I believe these are the important ones for an SD card based ROM?
I suspect the main reason there's not much info out there on 32GB cards is that people are less willing to drop $50-80 on something that may not work (IF they're trying to run a custom ROM from the card). If you're not trying to set up a custom ROM install on the SD, get any card you want--you may appreciate that higher sequential read/write in the higher class cards when you're moving multiple GB of movies or music to and from the card.
From everything I've read, the size of the card makes no difference whatsoever. The only reason people harp on the 8GB and 16GB Sandisk cards is because those specific models (both class 2 and 4 in those sizes) have been tested many times and return both reliably high small-block random writes and positive anecdotal reports for running ROMs. The size, manufacturer and class are irrelevant in and of themselves: they just let us identify specific models identified as most consistently working well.
Also, CrystalDiskMark is not malware: just do a custom install and choose not to install whatever is bundled with it (do this always for all software, I'd say). It's whatever program they use to suggest other software that triggers the false positives in security programs.
I have a moto g 2nd gen and I want to buy it a 64gb micro SD (formatting it to fat32 for it to work). I have 4 options, a Toshiba, a Kingston, an adata, and a samsung evo. Do you have one of these? Which one do you recommend?
Important is that it is a class 10 card,just because of the faster read/writespeed. I tested several class 10 cards (Samsung,Kingston,Hama,SanDisk) with Crystal DiscMark and the differerences were mostly marginal. I bought myself a Samsung because I could get it as a special offer. In official testings this card is mentioned to be one of the best.
The Samsung SDXC PRO 64GB is a little expensive but fast and therefore a good deal,also the SanDisk SDXC Card Extreme Plus 64GB. But in my opinion a Samsung Evo 64GB is doing a great job too and is a good choice.

What microSD cards do you guys recommend for the Note 4? I'm going to be honest, I have never bought a microSD as I have never seen the need nor had a phone that supported it. Now, being a first time Note user and seeing their value with having to Odin firmwares and such, I was wondering what you guys would recommend? I see Samsung Evo has good reviews and SanDisk seem to have a lot of buyers. I hear a lot of people complain about their microSD cards getting corrupted and/or breaking down so obviously that is something that I would pay more for to get a nicer version. I just have no experience in this field. Any help would be greatly appreciated.

I wind up living with my Note and find more and more uses for it. I would get something great because you are almost certainly going to use it.
I would suggest Samsung 128GB MicroSDXC EVO+ Card - MB-MC128DA/AM, about $105 on Amazon. Lots of storage, about as fast as it is going to get with that much storage (you may really need the speed and storage for video).
If you have the power you can try new things and it is fun. If you cheapee out your weenie machine may be a drag - slow or not enough storage or mabe new applications won't work to full advantage. Sure enough as time goes on there will be amazingly cool apps that will use whatever horsepower they can get. If you want to take full advantage of that beautiful new Note dont saddle it onto a donkey, go for the stunning racehorse.

I recently bought the Samsung 64GB EVO Class 10 Micro SDXC on Amazon for $22. I can honestly say this has been my best card, the writing speed is incredible and unlike the SanDisk 32GB Class 10 I used before it hasn't given me any troubles at all. I can't recommend the Samsung series enough.
Sandisk 128gb is $60 on amazon. Sandisk is highly compatible with lots of things. Not that the other SD cards wnt work with note4, but other electronics don't play as nicely sometimes. Also, they're very reliable. And usually not the fastest, but the tradeoff is reliability.

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.
I'm planning on to buy a 64GB SDcard, I'm currently in India. I need the best read/write support. I have a 250 mbps WiFi connection. I just don't want my SDcard to bottleneck the download speed. I just don't know about these SDcards and stuff. Please help me.
sandisk extreme or extreme pro... here
(obiouvsly you'll have to source a local deal)
if not available, you want to be looking for A2, U3 v30 cards
Sandisk or Samsung, I use them both and haven't had any problem. UHS 1 is the minimum speed if for modern phones.

I read an article saying that a2 sd cards is not yet supported in Snapdragon 845. If that is the case then it's better to use an A1 sd card to save money.
I don't trust SanDisk anymore after years of experience on many devices, nor other brands frankly, Kingston is the worst.. Only use Samsung Evo cards now. Also many fakes for all brands, even Samsung on Amazon.
I would also suggest Samsung evo
Samsung works ok in pocoloco
