[Q] SDHC 32 gig class 6

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.

Funny how all the Transcend cards in all 3 Nooks in my house are brilliant. I've used Transcend for years and have never had a problem, be it in my cameras to my phones.

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
http://www.amazon.com/gp/product/B004G7D0IW
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!

I tried downloading that and it got flagged as malware by Microsoft Security Essentials.

Rocking a 32 Lexar Class 10 here. Just download SD Tools from the market and its running 11 MB/s write and 25 MB/s read.

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.

[Q] Note sdcard read speed.

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.

Can anyone find definitive documentation that the sd card reader supports U3 speeds?

My gear 360 thumbnails seem slow reading from the sd card in gallery.. it looks like a class 10 U3 card will resolve that slow red issue, but I can't find any documentation anywhere that the note 8 supports U3 speeds, and I read if it does not, then the read speed will actually be slower.

Considering that if you got the wireless charger and SD card the SD card that was in that package was a u3 class 10 I'd assume that the Note 8 supports it

That's the problem... Everyone is assuming it, but no one has actually found out for sure.
Two guys who do have u3 cards are getting read speeds of 37...but the cards are rated at 90-100 transfer rates.
Granted speed depends on a lot of factors, but only getting 30% of a cards speed doesn't seem to me to have real full u3 speed support.
Two calls to Samsung, and neither support agent could confirm it, and two additions Samsung health questions also could not confirm it. They referred me to third party magazine articles recommending all different speed cards, and their definition of SD card specs only seems to be of capacity, not speed.
That's why I asked here, because the information just does not seem to be our there at all, and two people testing first cards both only had partially improved speeds, no where close to how fast the cards should actually be able to transfer.

Best MicroSD Card?

Trying to choose what MicroSD card to get for my Note 9
First is
Samsung Evo Plus 256gb
Link:- https://www.amazon.co.uk/gp/aw/d/B06XFS5657/ref=cm_cr_othr_mb_bdcrb_top?ie=UTF8&th=1&psc=1
Second is
SanDisk Extreme Plus 128gb
Link:-
https://www.amazon.co.uk/gp/aw/d/B07FCMRBTM/ref=psdcmw_1345826031_t3_B07FCMKK5X?th=1&psc=1
Right away you'll notice one is 128gb & the other is 256gb this is because the storage isn't too important, 128 is enough, 256 is the same price..
However the SanDisk one is A2 certified & V30 certified which the Samsung one is not, also the SanDisk has a 170mb/s read Vs the Samsung's 100mb/s read
Will the A2 & V30 certification even make a difference on a Note 9?
Appreciate any help or opinions? Thanks

The impact between the Samsung SD & Sandisk is not so Big I guess. Anyway i have a pro SD card from Samsung in my Note 9 & what to Say? Works perfect.. but if you get more space for same price..i would recommend the Samsung anyway..

That depends on what you're going to store on the SD card. If it's music or data that's doesn't need lightning access, go for 256GB. You're getting 2x storage with same price. 100 mb/s read is not less either.
The premium cards with names like Extreme or Pro advertising more than a hundred MB/s speeds are useful for cases like 4K video recording or RAW (or burst shot) photography.
I assume your Note9 still has plenty of storage to do these stuff. You can always record or shoot photos on internal storage and can anytime move the older ones to SD card if you get low on storage.
As I have said, please do share the reason you're thinking about getting 100+ GB SD card.

Mainly high quality photo's, high quality videos, high quality music often .flac instead of .mp3 & possibly some movies..
You're correct assuming that my Note 9 has plenty of storage left I've only used 29gb out of 128gb, however I prefer to keep music, photos & videos on a removable storage
The reason I'm thinking about getting 100gb+ is because I already have 3 MicroSD cards full at this moment in time, they're 32, 32, & 16 so that is already 80gb in total, so a 64gb MicroSD wouldn't be much use, the next one up is 128gb...
I want to move all the contents of the 3 MicroSD cards & move them on to the 1, easy to manage my files that way
I often backup the MicroSD contents on to my PC twice a month, I'd want that to be fast as possible
It's my understanding that the V30 certification is for filming & saving 4K video directly on to the MicroSD right?, That wouldn't be too important as I'd film it on to my device first then move it later on..
However the A2 certification is regarding read speed right? Which is 170mb/s on the SanDisk compared to 100mb/s on the Samsung, how noticeable is the extra 70mb/s and it what circumstances?

Yes, V30 means the card can sustain continuous video recording at 30 MB/s. You said you're going to record on internal storage itself (and you should be) so that shouldn't matter much to you.
That enhanced write and read speed (with some caching and efficient performance) with A2 can give you higher speeds while backing up the data to your PC but it's just 1.7x with 0.5x storage (not mentioning other bottlenecks for maximum speed). I consider the 256GB to be having far more VFM. Your backup frequency will also get halved with double storage, no?
You can never go wrong with either of these. Premium memory cards like V30 are meant for professional video recorders and camera. Playing even 4K videos requires around 50 mbps and FLAC are under 1 mbps.
I think you should get double the memory for same the price!

Yes I'd record on internal so V30 can be forgotten about pretty much
Could I also expect bottlenecking on the Samsung 256gb?, & yes my backup frequency would probably be reduced to once a month with the increased space
Yeah the V30 certification would definitely make a difference to me if I was using a professional camera etc. But as it's my Note 9 & I'd be saving to internal, I don't necessarily need it
I'll probably end up going with the Samsung 256gb thank you very much for your help!

Yes, by bottleneck I mean the capabilities of Memory Controller and Card Readers.
Upon reading over the internet, I have found most SD cards averaging Read/Write below 70 MB/s. Read one benchmarking here for Samsung EVO+ 256GB UHS-1 microSDXC U3 that advertises speeds over 90 MB/s.
The bottleneck here is the card reader on Note9 as well as the hardware limits.
Even on a PC, the card interface or the adapter (in case you use that) could be bottlenecks.
I think you're going the right way with double the memory with same the price. There's diminishing returns on higher performance with increasing price.
Sent from my SM-N960F using Tapatalk

Both are good brands. However if you are probably gonna get the same data transfer speeds on your device as the Note 9 doesn't have a very fast microSDcard writter in it.

I have a Samsung Evo Plus 256gb and it's good and fast. I can only recommend it

Question SD card write speed?

Does anyone use a SD card with this tablet? I've bought a few different SanDisk ones and have been disappointed with the write speeds which is most important to me.
I understand that you'll never be able to achieve the advertised speeds, but no matter what card I use the write speed is always capped at 20MB/s.
When I looked at the Amazon reviews of these cards people were complaining they weren't getting the full write speed, but the lowest speeds reported were at least 50MB/s, not 20MB/s.
I've looked online and since there is little information about this model I haven't been able to find any others who could confirm that this tablets SD write speed is capped at 20MB/s. If so then there would be no reason to waste any more money on SD cards.

The SD card speed is limited by the bus speed of the tablet. Buying high speed cards to use in it is a waste of money.

I believe it is a USB 2 bus bit I'm not certain. You have to realize that this is a budget priced tablet and isn't going to have the performance of top-of-the-line ones.
