SanDisk 64GB Micro SDXC

Who's buying one of these, they don't come cheap at $219, but according to this article:
http://androidcommunity.com/sandisk...working-on-multiple-android-devices-20110927/
They work on the Evo 4G, and if they work on devices from way back then, then it should work on the DHD/Inspire.

Can anyone test it for the DHD?

I'm Android Communities source - here is the source material (which includes a YouTube video that they omitted):
http://www.androidnz.net/2011/09/sandisk-64gb-micro-sdxc-cards-confirmed.html
I'm really very certain it will also work in the DHD, but as always confirmation is nice - I will be at an Android meetup next week so hopefully can test it in lots of devices (bound to me a DHD there).

Afaik, it shouldn't be able to access more than 32gb of its memory, even if it works.

There are also reports that they are working on many older devices for those wondering. Some include the EVO 4G, original Galaxy S, and even the HTC Desire Z (aka T-Mobile G2). With both old and new, smartphones and tablets being able to take advantage of the 64GB SD cards this is a good sign many more will have the same fate.

http://en.wikipedia.org/wiki/Secure_Digital#SDHC_and_SDXC_compatibility_issues
SDHC and SDXC compatibility issues
In the 3.0 specification, the electronic interface of SDHC and SDXC cards is the same. This means that SDHC hosts that have drivers that recognize the newly used capability bits, and have operating system software that understands the exFAT filesystem, are compatible with SDXC cards. The decision to label cards with a capacity greater than 32 GB as SDXC and to use a different filesystem is due solely to the limitations in creating larger filesystems in certain versions of Microsoft Windows.[citation needed] Other operating system kernels, such as Linux, make no distinction between SDHC and SDXC cards, as long as the card contains a compatible filesystem.
SDHC and SDXC cards and hosts have these compatibility issues:
Existing SDHC hosts will only support the SDXC cards at up to UHS104 speeds.[45]
SDXC hosts are backward compatible with SD and SDHC memory cards.[61]
The operating systems that support SDXC, as of 2011, are: Linux (with a proprietary driver for the exFAT filesystem),[62] Microsoft Windows 7, Windows Vista SP1+,[61] Windows XP SP2 or SP3 with KB955704,[63] Windows Server 2008 SP1+, Windows Server 2003 SP2 or SP3 with KB955704, Windows CE 6+, Mac OS X 10.6.5 or later.[64]

Why would you buy this card for 219$? It's way too much...I just bought a 32GB class 10 card on eBay for 51$ (Ridata brand. Although it's not Sandisk but it's a known memory cards company).

Price goes up logarithmically as you aproach the top.
This has been true for almost everything, everytime in technology, from processors, ram, motherbards, hdd.. etc
But no, i would not give 219$ (or half of it) for a 64gb card. If it where a 2tb card, perhaps

It works as it should. Let's get something straight, the Desire HD DOES NOT SUPPORT SDXC. That, doesn't mean it will not work. Just that HTC washes their hands of it.
Now, from that wikipedia article:
In the 3.0 specification, the electronic interface of SDHC and SDXC cards is the same. This means that SDHC hosts that have drivers that recognize the newly used capability bits, and have operating system software that understands the exFAT filesystem, are compatible with SDXC cards.

I'm currently looking at the new samsung cards. I believe they are the fastest class 10 micro sd's around with a 24 MB/s read and write speed.
Sent from my Desire HD using xda premium

You should be advised though, that's MAX/PEAK transfer speed.
The sdcard reader/writer in the dhd might not even support it!
Anyhow, how much are we talking about ?? (€/$)

Can use this?
Wow i need it Because 8GB class 2 its awful

Why do you think so?

Isn't 64 gig to big for dhd. May be lagging a bit?

Is you 500gb computer any slower with 1tb ?
Only if you have ALOT of files on one folder, will it be slower...

That's good point I have 2x1tb plus 1 TB external works fine My worries came from old phones when I used to put 1 gig in Motorola e398 (clasic phone) it freaz on boot. Propebly I forgot what century we live in and that DHD spec is much more advance

I want buy it since my 32gb is full.... It's fully compatible or not?? Can I purchased it without problems?

According to what has been posted in this thread ... yes, its fully compatible.

the sandisk 64GB works on my htc inspire, so it should work on htc desire hd.

can't mount 64gb microSDXC ultra sandisk

this card works fine on my S3, i'm really shocked as my 10.1 note does not even mount it, when i install it it says its now safe to remove, tried restarting, formating, swapping with 32gb and it mounts it fine, please help as i paid alot for the 64 and its not refundable

The problem is that right now the note doesn't support exfat whichthe 64gb cards ship with. I can confirm that a 64gb card does indeed work if is is formatted as fat32. There is a guide out there somewhere for formatting the 64gb cards as fat32 (windows doesn't show that option for 64gb cards) but I can't remember where I saw it. A Google search should be in order for that.

note 10.1 is not as good as s3, s3 accepts the 64gb format, to make it work on the note 10.1, you must downlaod a tool on windows to allow format memories bigger than 32gb to format to fat32, although it wont be the fastest, but atleast got it finally working
so i confirm the memory working but not out of the box, you need a custom software on windows to format fat32 as windows maximum formats 32gb to fat 32

I am sure someone willl bring some mods soon that will make ntfs support... Its already there for some other phones.

I can confirm thst it works too. I havd a Sandisk 64 GB sdxc UHS-1 Class 10, which I formatted to FAT32 on my W7 machine with a program. The card still didnt mount on my Note 10.1 until I tried it on my GT-N7000 Note 5.3, which formatted again. Works fine now.

Some Notes seem to be shipping with the exFAT module, others aren't.
I know UEALGB doesn't support exFAT.

My Note came with...
Baseband version N8000XXLGA
Build number: IMM76D.N8000XWALG9
...and it reads exFAT formatted cards beautifully.

All 64gb cards read as 59gb... Its due to the manufacturers calculating 64000x1000 instead of 64000x1024.... The tab uses the binary system - that a kilobyte is 1024bytes not 1000bytes. This happens with ALL digital media...

[Q] 32Gb classes 10 & 6 MicroSDHC UHS-1 not supported by TF300T(G)

Hello,
Preamble: I curently own a TF300TG on JRO03C.WW_epad_10.4.3.9-20121106 stock, locked and not rooted
I've recently bought a Samsung 32Gb Class 10 MicroSDHC UHS-1 and the tablet failed to recognize it, while my i9000 and the PC had no trouble accessing it.
I've tried formatting it again to FAT, exFAT and NTFS without any luck.
Next I sent an e-mail to Asus support, who replied that my and any other card above class 6 is not supported, which seems to be backed up by statements of some people having similar trouble with smaller sized cards of class 10.
This post servers both as a warning to those interested in buying a card for their tablet, and as an interrogative mark for everyone: do you have a working class10 microsd in your TF300T(G)? If so, what make is it, and what firmware are you on? Do you think this is a hardware or a perhaps a stock firmware limitation?
Thanks,
Cheers

It worked on ICS rom from Asus.
Asus JB rom I do not know.

It works with Surdu_Petrus roms and kernels
Can not get it to work with Clemsyn kernels

Hi guys,
Given your answers, and to the fact that my old i9000 recognizes it without problems, I tend to incline it'd be a stock firmware limitation, rather than a hardware one... Also I got another reply yesterday from Asus, which among others, reads: "This is a hardware limitation, not a software one. Although with a firmware update you might be able to use your card"
I'm thinking of buying a class 6, and keep this one for my Hero2.

I'm wondering if it's not a UHS related firmware limitation...

Hello and happy new year, I'm back some news:

The title does not say anything about the dock / extension kb, and we're talking about Micro SD(HC) not about SD cards, but just to make it as clear as possible yes, we're referring build in MicroSD slot.

What is the largest microSD card proven on the PhotonQ LTE? details?

Motorola's website says 32gb microSD is the largest supported by the Photon Q LTE and the Droid 4.
But, I have read the Droid 4 is reading 64gb microSD cards.
So, what is the make & model of the highest GB microSD card that's been proven to be read by the Photon Q LTE stock?
Modded?
Method of Modding?
Recommended microSD card and vendor?
Thanks in advance.
These are the 2 I am deciding between on Amazon:
http://www.amazon.com/SanDisk-Mobil...1364805252&sr=1-2&keywords=Sandisk+Ultra+64GB
http://www.amazon.com/gp/product/B0...le_2?ie=UTF8&psc=1&smid=A02211013Q5HP3OMSZC7W

I'm using the SanDisk 32GB Class 10 microSD card you linked to, and it works great. I've read that 64GB cards work, but I don't own one of my own to verify it.

Typically, 64 GB cards will work, they just need to be formatted to FAT32 before the phone will read them. Most/all 64 GB cards on the market are shipped formatted to ExFAT.
Personally, I am using the 32 GB class 10 SanDisk card with no problems.

Using ADATA 32 GB card, class 10, no problems.

I just tried using one of my 64GB class 10 cards this morning. No bueno. I tried formatting as NTFS or exFAT. FAT32 was not an option for formatting a card that size.
So I tried to format it from the phone directly, but it wouldn't do it.
I believe the support for 64GB is in Android 4.1

You have to format it either over a tool like "MiniTool Partition Magic" or use linux.
Microsoft is blocking FAT32 on "too big" external storages...

32gb SanDisk card here.
I think the 64gb story is correct, it will work formatted FAT32. Use basically anything but the built-in Windows utility to format...

samsung 32gb, no problemo.

I am using a 64 gb San Disk. I have been using it since February with no problems. :good:

You'll have to make sure the card is formatted FAT32. I've heard a lot of the cards larger than 32gb (beyond SDHC) come formatted exFAT.

So, I called Moto Tier 2 tech on the phone and they told me the Micro SD will support Class 10 speeds.
Then, they tell me that 32gb should be the max used.
They said that "If you use a 64gb card, it will cause issues and errors because it will overwhelm the hardward and RAM of the PhotonQ".
I was about to order a Snadisk 64gb Class 10 card, but not I'm not comfortable.
Any thoughts ????

I'm not an expert, but that doesn't make much sense to me. I've never seen that to be the case with anything else, either it works or it doesn't.

I'm also not an expert, but there was a similiar problem on PCs with 32 bit and HDDs with over 2 TB.
Some programs could not use the space over 2 TB or made problems with those HDDs.
Maybe there's a limitation in the ARM architecture?
Can only guess.

The hard drives over 2.2TB is a problem with the MBR

No, that was not the only problem.
In connection with cryptsetup the "plain" module had also problems.
The "plain64" module have no issues. -> http://code.google.com/p/cryptsetup/wiki/FrequentlyAskedQuestions#5._Security_Aspects (look at 5.15)
As I said, I am not an expert, but if there exists a plain64 (like 64bit?), I assume the old one was 32bit code.
It's just a guess, I don't know exactly, why the problem exists.

Honestly I think this is just Motorola practicing CYA (Cover Your A**). Most end users aren't going to have a clue that an SDXC card needs to be formatted in FAT32 to work with the phone, nor are they going to know that they need a third party utility to do so in Windows. Motorola probably just doesn't want to deal with support issues and unhappy customers when a 64GB card doesn't work out of the box. I see no real reason why it would "stress the hardware" any more than any other SD card, it doesn't require more voltage or amperage.
There is no issue with the ARM architecture, as it handles 64GB just fine on other phones, once the card is formatted to FAT32.

If you are right, then I am sure, that a 64 GB will work.
A friend of mine own such a SD-card (if I remember correctly), I will ask him if I could try it out.
If he owns this SD-card, then he should be using it with a Samsung Galaxy S3, stock firmware.

MicroSD. Which one to buy?

I bought a 64Gb MicroSD for little money. It is not brand, but when I copy large amounts of files from the PC (ie music), then when I put it on the phone, the music disappears. This problem can be given by the poor quality of MicroSD? What do you recommend? A MicroSD Samsung Evo may be okay?

I have made (and still have) good experiences with Samsung, Toshiba and Transcend cards. Rather bad (or mixed) experiences with SanDisk cards. I wouldn't say that SanDisk cards are in general of bad quality - my guess is that there are many fake SanDisk cards on the market.
Currently I'm using a 128 GB Samsung Evo card.

Kingston may also be a good option. Using my 32GB Class 10 for well over a year now. Granted, I do not copy much between a PC and the card, but I do move a lot of stuff between the internal storage and the sd card.

Was using a sadisk 16gb card, and now a lexar 32 GB card. Virtually no difference, besides storage space. I find it unnecessary to buy an expensive cardz when I've never had a single problem with the cheaper brands, and not the "top of the line" cards like the overpriced Samsung cards.
Really, go with any brand. I see a lot of articles about certain cards having problems with the s4, but you gotta understand, those are isolated incidences, and the other thousands of people that don't have problems with their SD card and this phone don't go online to complain about them.

As for your particular problem, might be a problem with the connection between your phone and the PC, and not the SD card.
You should buy a different brand, and see if it does the same thing.

The Real SPEED of S4 !!!!!!!!!!!!
I'm a pro of microSD and Galaxy S4.
Hear that :
Galaxy S4 can only read and write on external microSD card at 21,7 Mo/s max !!!!!
So buying a Sandisk Ultra (read : 45, write : 13) would not be a good choice according to me...
You should buy a Sandisk Extreme (read : 90, write : 45), to enjoy a bit more speed, for 3$ more expensive...

I had a bad experience with Lexar ( same for this guy -> https://youtu.be/aO-imP0qTQY
At the moment I'm using samsung EVO+ 128gb and its perfect got it for around 30$US from a store (Best Buy)

SD Cards recommended (and not)
Mostly any BRAND SD cards are recommended. Which ones you ask? Lexar, Kingston, Adata, SAMSUNG. It's going to be sad if you buy a Generic or Off-Brand one. Why? Well, they don't always come with their real capacity (claiming to be 8GB, and they're really 4GB or 2GB), they're REALLY delicate or unreliable, and some are known to not work AT ALL out of box. So yeah, there's the best, VERY-IN-DEPTH guide the world has ever seen. Maybe.

Probably just an isolated incident. Had this lexar for the past 7 mos. and still working flawlessly.

I would recommend KIngston at any form

Got a 32Gb Samsung EVO microsd with my S4 3 years ago - it lasted about 6 months before it packed up. What a bunch of crap from Samsung.
Currently using a cheap old class 4 sandisk 16Gb (which was inherited from my old Blackberry 9300 (from back in the day ) now for the past 2 years or so without hassle - smooth sailing! And the sdcard is probably 4/5 years old now!
Moral of the story: Fastest/most expensive/<insert brand name> IS NOT ALWAYS the most reliable/best way to go.

I always use either SanDisk or Samsung EVO/EVO+, never had issues with either.

So what you're saying is that even though the phone can only read @ 21 mb/s MAX, buying a card that has 90 mb/s read speeds somehow makes it faster?

Yes, S4 is limited at 20Mo/s in read and 20Mo/s in write,
so no benefits at all with a sdcard with 90Mo/s in read,
but 40Mo/s instead of 10Mo/s is a very big benefits(10->2X faster !!!)
So I have bought a 200GB Lexar 633x (90, 40) at 120$, and it works like a charm on my S4 !

EVO 64B here...no promblems yet. :fingers-crossed:

How much did you pay for it? I find Samsung to be over priced. Got me a lexar microSD card at a cheaper price, and no complaints.
I think brand name SD cards are overrated, IMO. Some of them get bad reviews, and say how they mess up badly after a while, but I think that's just a case of rare instances, or got a defected model. Never had a problem with the cheaper brands, ever.
