[Q] MicroSD capacity?

Anyone know what size AND speed MicroSD card the DInc2 supports up to?
I would love a link to somewhere that gives the specs...
And maybe even a link to a good deal on cards?
Thanks!

By claiming to support microSDHC (micro secure digital high capacity, SD 2.0), they are kinda required by specification to support any card that follows the microSDHC standard. I know this doesn't always happen, but that's the way it SHOULD be.
With that said, I have a 32gb class 4 card in my I2. 32gb is the limit to the microSDHC (rather, limit to SD 2.0) standard, so I suspect any microSDHC card will work.
There is no explicit support for microSDXC (micro secure digital extended capacity, SD 3.0 and 4.0, the standard that allows for up to 2tb capacity by its definition, though I think 128gb is the biggest available at the moment, and those are expensive and hard to find). Apparently the specifications allow for SDHC (and microSDHC) hosts to support SDXC cards at SDHC speeds as long as the host supports a filesystem that can format a volume larger than 32gb (FAT32 has some addressing and table allocation limits, which is why Microsoft stopped using it for primary volumes). Considering Android uses FAT32 and not exFAT (Microsoft updated version of FAT that is more efficient with larger volumes, doesn't have the low addressing limits, and optimized for flash media), I would not count on it properly supporting SDXC quite yet.

I found a Spec List that at least confirms your 32GB figure, but I am still in the dark about what class the DInc2 supports up to.
Anyone?
Anyone?

It SHOULD (key word: should) support up to class 10. However, this may be dependent on model of card. I know the Eris would work with some class 6 cards in the higher capacities, and not others, and would only work with lower capacity class 10 cards.
Best I can suggest is to buy and try. Make sure you buy from somewhere with a good return policy so that you can return a card that doesn't work with your I2. I will say the Kingston Class 4 32gb card has no problem handling the 720p recording.

Is there a way to check what kind of data transfer rates are occurring? Or would the card be unusable/unrecognized if the class was unsupported effectively letting me know?

If the controller/device supports a higher class card, it will work with it at the highest speed possible, either limited by the card or the controller.
If the device doesn't like the card, you'll generally know pretty quickly. I've only seen one instance of a device not handling a card well and displaying that fact through data corruption and it wasn't with an Android device (it was a cheap digital camera). On the Eris, the card just wouldn't be read/would indicate it's bad.

Memory cards supported?

Hey guys,
I can't seem to find any detailed information about memory card support on galaxy A5 2017. I was thinking about buying a microsd UHS-3 class 10, is it supported? or waste of money? i heard good opinions about this specific one: Samsung 64GB 100MB/s (U3) MicroSDXC EVO
but again, i'm no expert in the matter. My goal is to install apps on it, not much photos. I want the fastest card, i hate lag
thanks in advance

Well there are 2 slots on the phone : one for the sim card (obviously) and the other one for the memory card.

Yes @amithiel A5 2017 supports UHS 3 memory card and the limit is 256gb. However I wouldn't recommend spending so much on UHS 3 as these cards are useful only for high end cameras like go pro and security cams. On phone you wouldnt find much difference. Telling from experience. I am using 64gb UHS grade 3. And it give me 25 mpbs transfer speed when transfering files from pc to sd card when it is connected through phone. And gives 35~38mbps speed when directly connected to pc through card reader.

I generally get 128g SD chips for my phones. Haven't filled one yet!

If you want to use adoptable storage, you would need the fast class 10 card, slower cards simply don't work well enough. Even if you just run apps off it, the extra speed is worth it. <It is not that much more than slower cards, maybe 10-20% more ... in Canada at any rate.>

what micro sd are you using?

what micro sd card do you recommend which is compatible for the razer phone? looking for a bang for the buck with fast read/write and doesnt need to be above 512gb. Thanks

I have personally gone with the Samsung 256GB Evo Plus Class 10 / U3 card from Samsung Mobile on amazon. Currently still on sale £114, I never really use the camera unless on holiday or need to snap a quick pic or video of something as its quicker than writing it down. Conisdering my last family holiday I took the 128GB iPhone 6s size wise the 256gb is more than enough as the only game i have installed is hearthstone. All my apps take up a total 21.33/58.90 (GB) on the internal drive leaving the SD for the camera.

i have a toshiba 128gb, class 10, u3 and the phone lags considerably when using the external cards memory to access.
i have it formated as internal memory as well.
i thought U3 class 10 is the fastest you can get but it still tells me the card is slow when i go to format it.

Is UFS card supported?

Hello.
The phone has UFS 3.0 storage support, but does it support UFS cards?
I've tried 256gb card and my N10+ doesn't recognize it.

I believe the best card you can put in is microSDXC, the UFS is likely purely the internal memory as UFS isn't compatible with the MicroSD formats so making the slot take UFS would of likely made getting expansion cards harder and potentially more expensive.
so the Note 10+ won't recognise the card as the pin locations on the cards are totally different, so the card is likely just not making any contact inside the phone so likely acting as if you just put a blank in.

When I first heard about that standard I was fascinated. Samsung invented that storage standard and they are MUCH faster than the SD card standard. It could be that what it would cost to make that a standard used by other device manufacturers unfortunately I believe is a hurdle too large for Samsung to overcome. I believe that is the only reason why Samsung does not bother. However, if they offered phones that could handle the UFS cards, and also offered the UFS cards - (and this is key) - and then licensed the technology to other manufacturers - I believe they would sell so many that it would become a standard that might take a while but would most likely eclipse the old SD standard. Maybe there is some kind of design flaw that Samsung is not explaining to people that makes it more expensive to be able to utilize the UFS standard? Thoughts?

Just adding to the conversation, got me curious...
Checked Samsung's site, seems the UFS Cards are only compatible with certain models of Samsung's laptop PCs.
For those who are interested, see specs in the link below for compatible device model numbers (same link as in the OP) :
https://www.samsung.com/us/computing/memory-storage/memory-cards/mb-fa256g-am-mb-fa256g-am/

2 years since UFS card was released, only 26 devices support it...way to go Samsung..

it's the case with most storage devices, you go with a standard connection or you struggle to get others to pick it up. had Samsung started making this standard in their phones it likely would have seen a larger outcry than the removal of the SD slot as it would force those who use them to buy new cards as it has no cross compatibility with SD.
had they found a way to do this expanding the SD technology it would have became far more common but on a new format it will take a long long time to get traction and is more likely to be put in devices that can have multiple storage connectors, as it allows them to give legacy support with support for the new.
then there is getting third party support iif it is something that needs to be licensed from Samsung for every device it goes in, as it will just add production costs to devices.
it's the same if you look at M2 hard drives in PC's, PCIe drives have been around for years the M2 connector has been about a fair while now, but it still has relatively little traction in hardware and that is built on a standard system that has been in computers for years, for a closed system built from the ground up it is going to take a long long time to get any traction if it ever can demand the market share. while Samsung is massive in the memory market the internal support is way more likely than any use for adin cards with how large base storage is getting in some devices. the memory cards now are used for little more than audio/video/picture storage so speed isn't really as important as if you are editing you have a large high speed storage you can utilize first and really if you are outside that storage space you are going to want more power than a phone for the editing.

The Note 10/10+/10+ 5G supports UFS 3.0 for internal storage, not for microSD storage.

Why does the card need to be physically compatible? As far as i can tell the rough dimensions of the cards are close enough they could make a dual purpose slot, face the card down for micro sd face up for ufs, max they would need to supply a second sim/storage tray in the box, but that doesn't seem to be a huge hurdle

If my memory serves me correctly you are right.
The 10+ nonetheless writes/reads to a fast card very fast. The weak link is transfering large files via USB or cloud not between internal memory/SD card.
A V60 rated one might do better but I'm having zero issues with a Lexar rated at V30. To have a fast handheld PC with close to a 1 tb of memory is unbelievable.
Best of all you can use the SD card as a data drive.
Yeah I got a hard on over this:laugh:
Complete OS reloads/data restores can be done with no PC or internet needed. The 200+ gb music library Poweramp uses is on the SD card. Poweramp restored its playlist from this new data base in less than a minute, and plays them flawlessly.
Get a name card with a good reputation as reliability as well as speed is what you're paying for.
A .5tb V30 Lexar can be had for around $80 now.
Format in phone; good to go.

Best microSD card for adoptable storage on A5 2017?

Title. Is there a max storage capacity, too?
Also, is there an updated tutorial for getting adoptable storage working? The one I found is pretty old.

I believe 256GB is the maximum. Any reputable manufacturer is fine but make sure it is a high speed (class 10) card.
Personally never bothered with adoptable storage. If the card fails for whatever reason...your screwed.
I prefer to keep SD card separate. Just feels more secure, but each to their own I guess.
