does anyone know the max sd card transfer speed of the pad, and the dock?
i am looking at a 128GB SDXC card (yes, its a lot, but this is replacing a dead laptop for the foreseeable future) , UHS-1 60mb/s, or a 45mb/s one. will the UHS card actually have any benefits in the dock, or simply when transfering data to it from the PC.
many thanks!
I'm currently running a Class 10 (200x) 32 GB SDHC in the dock, branded Dane-Elec. Runs fine. I don't know if it takes 32+ GB cards, though... And to be honest, while heavily dependent on what you actually do with it, for most purposes a high-speed card should suffice...

I'm currently using two Sandisk cards:
- microSD class 10 30MBps SDHC Ultra (16GB)
- full SD class 10 SDHC Extreme 45MBps in the docking station (32GB)
They get better speeds than the built-in disk, but it is still not great. It seems to be about 15-18Mbps write for SD, 6Mbps write for microSD and 30-32Mbps read for both (as compared to 12/18 of the internal memory).
The fastest way of moving data still seems to be external USB HDD...
Hope this helps, haven't tried any other yet. I have tried both FAT32 and NTFS though. They seem to give similar results (I had no problems using NTFS on my SD card so far, which is a good sign).

I haven't used an external drive yet, but I agree with the observation that the transfer speed is not optimal, no matter what card I plug in (I have transplanted a few I normally use in my DSLR just for testing; they are all fast cards, as you can imagine). I transferred several documentaries and a lot of photographs yesterday evening and it took ages, mainly due to the fact that the transfer process hangs up the entire device (!) regularly. It seems to happen after about 70 to 80 MB are read into (temporary?) memory and apparently are only then buffered out to the main storage. Let's hope a custom ROM can straighten this issue out...
Thanks. Given these figures, would you install apps on the main memory, if a 30mbps rated micro sd for best performance?

In my case internal memory is faster than microSD. You don't really have the option, unless you play with the filesystem and mount your MicroSD on /mnt/sdcard instead of /Removable/MicroSD. In the Infinity /mnt/sdcard is just a folder within the internal memory by default (many apps use it though, so they had to arrange it this way). I don't think there is any reason to change this, as internal memory seems faster and that's whole 64GB of it (OK, maybe 56 available, but still a lot..).
Perfect thanks, I thought though that there were current issues with I/O speeds until someone could fix it in a Rom. Or has this been addressed in the new firmware?

Hopefully I could tell you in a few days, but honestly I don't think it has (can't try it out yet, as the firmware released is Taiwanese version, and I'm on the World-Wide).
The Infinity is not that far behind other new tablets or rather it's not only TF700's problem, see http://forum.xda-developers.com/showpost.php?p=28416635&postcount=2842
However, after changing the scheduler to sio and doing some tweaks (see my post on it: http://forum.xda-developers.com/showthread.php?t=1758160), it's running pretty smoothly (unless you want to do a lot of CPU-heavy jobs while having huge reads or writes in the background, in this case it can get frustrating, but.. there is no real alternative these days).

This. As i've ranted earlier, the new firmware provides fixes for camera issues, not for the I/O the TF700 so obviously suffers from. Having said that, it is not like the tablet in itself is useless as it is -- far from it -- but remains a mystery to me why they didn't spot this in advance (like with the Prime's issues with GPS and wifi), It seems like ASUS develops a device by letting several teams work onindividual components, and, when they get their specific part up and running, just put it together and relese it. I have a distinct feeling that neither device was actually and properly tested.
But, still, I'm pretty happy with the device overall.
I think you need to read this thread:

From what I see my UHS-1 card that doesn't work is initialized as DDR which means the max speed for the TF700T µSD is 50 MB/s (as that is the only DDR speed).
The full size SD socket uses a USB host so the big question is is it USB 2.0 or 3.0!
All specifications says USB 2.0 for the dock, so I would assume that's correct, even for the TF700 dock.
Asus has finally responded that there is limited UHS-1 support in the µSD slot.
For now you are better off not trying UHS-1 in there. The may come up with a patch...

Careful there with a 128gig card, I read somewhere that there is a 32 gig upperlimit on recognizing cards and sticks...
tho I do wonder if you formatted it into enough partitions it might read them all?

If the dock uses a sdhc compatible controller and simply exposes the card as a mass storage device for the system, then there is really no such limit. The SDXC cards which supports >32GB does so due to the SD's FAT specification not for actual addressing and such.
SDXC cards are accessible as SDHC but standard specifies ExFat as default filesystem. This may not work on units not compatible with ExFat, but a reformat will fix that. In the TF700T's case we have already seen users use 64 GB cards breaking that 32GB barrier.
We have also seen the TF700T mount ExFat, although it seems to fallback to NTFS.
The thing he should be carefull of is UHS in the µSD socket as it's still wonky.
In the dock I suspect a UHS card will simply be treated as a normal SDHC card, but UHS cards usually have better class speeds so may be a benefit even with the dock doing USB2.0 hosting.
Edit:
To back up my claims see here...

Hi all,
I'm looking to get a new microSD card and - having a more modern device as well as the venerable HTC Desire HD - a question arose regarding maximum microSD capacities.
What is it that actually stops a phone from recognising any storage greater than its stated maximum? The microSD standard is the same for, say, 32GB and 64GB cards, so at what point does the phone say No more!? I assume it's not a software issue; perhaps something to do with the bus that connects the storage slot to the phone?
Which leads me to my actual question: surely, with a 64GB microSD card, one can modify the size of the partition to be 32GB (or less) and thus the phone will recognise it? For this question we can assume that the rest of the space is simply unallocated.
A follow-up query is "How, then, do phones handle external storage with multiple partitions"? Do they recognise multiple partitions up until their 'maximum size limit' is reached? Do they only see the first partition?
Thanks,
Jake
Perhaps it doesn't support that size memory card that you are trying to insert

Yes, I think you can do it. Make a new Primary Partition of your Pen Drive, with size almost equal to the maximum size limit of SD Card your device can handle
May be this help you
Hit thanks if helped
I got a 256GB SD-card recently. Only after purchase I bothered to check the phone specs, which clearly states that 64GB is max supported card size. Stupid, I know.
The phone sees the 256gb card, is able to read-write to it, but otherwise acts weird. Data amount saved to the card changes on every reboot, number of songs downloaded to card varies on every reboot. Either the card is faulty or its simply too big.
Noob that I am, couple of questions:
1) provided that the size is the issue, is using multiple partitions (eg split the capacity in two 128GB parts) worth trying?
2) are there differences on various ROMs on how they handle large capacity SD-cards? Currently running ResurrectionRemix 5.7.4-20161113 (Android 6.0.1)
Thanx and have a good one
SD cards support is more a matter of hardware than software. Otherwise even 2010 smartphones could run 256 GB SD cards.
I would say the card is faulty, since the phone wouldn't recognize it if it were to not supported. But don't take my word for it.
The reason why the S4 has the max capacity listed at 64 is because, at the time of its release, the biggest card was 64 GB.
256 gigs is way too high like Ow said.
Go with a type 11 64 gig memory card, I'm using a 32 gig type 1 and have to deal with errors constantly.
Partition it 4 x 64Gb using Minitool Partition Wizard.

It's likely a software/ROM issue as a friend of mine with a Note 2 has a 256GB MicroSD that runs perfectly.
The SDHX standard on the S4 can support MicroSD cards of up to 2TB theoretically.

Kernel issue?
Try a kernel that supports exfat. I have one on an S3 mini running CM 12.1, and I am using a 128gb microsd with no problems.
Can anybody confirm a 256GB card works? It should since my 32GB works as exFAT and if the last post says 128GB is also working, that would suggest all sdXC would work, no?
I got a 128gb (micro sdxc samsung evo plus) on my galaxy S4 I9505 and runs like charm.
I'm sure if it was 256gb would run with no problems as well.
So the problem is not the card capacity, that's for sure.
Hi there, not sure if this is the right place to answer this question.
Gutted to know that the amount of storage lost on a 400GB Sandisk Card was close to about 32GB. Of the 400GB capacity, 366GB formatted was available to store files. I found this out by multiple people and by putting in the adapter to my computer. I also realised the read/write speeds were slow but acceptable and comfortable for normal use. Later, I put the SD card into my phone (Xiaomi Redmi 5 Plus at the time) thinking it would work without an issue. Well, it did. In fact, it worked even better. Read speeds were close to the advertised amount at almost 100mbps and the write speed was just under 50mbps so I was happy. I also came to realise that the formatted capacity on my phone was showing as 394GB instead of the 366GB most people get on their computers.
I now move phone to the Razer Phone, as soon as I pop the SD card into the phone, it asks me that it needs formatting to a compatible format I believe as the 400GB capacity may have been too large or in the wrong file format. I haven't done so yet since there's about 25GB of files I want to keep (transferred from my previous 32GB card).
So I couldn't find the answers online for these two questions.
1) Why was the formatted size different on a computer, and on the Xiaomi?
2) If I were to format the SD card to a compatible format, I'd lose out on a lot of storage due to an unused partition. Correct?
Any responses are appreciated.
Thanks a lot
Guys sorry for this dumb question but I heard that the S7's maximum SD-Card capacity was 200GiB.
My phone is rooted with magisk and SuperMan-ROM 3 (later maybe LineageOS Pie).
What happens when I insert a 400GiB SD-Card which I could get very cheap this weekend?
Will it work fine with all the capacity?
Will only 200GiB be accessible?
Will it not work at all?
Thank you!

I've had sucess on multiple phones using SD cards that were bigger than what the phones said they were capable of. I look at is is they can only guarantee up to thier stated max capacity, anything above that and there is a possibility of problems or not being able to read it. But every phone is different.
If it's real cheap you could get it regardless and could still use it. I picked up a little adapter for $12 that holds a micro SD card, it's regular USB on one end (for computer connection) and micro USB on the other using OTG function. Nickles for size comparison
I can confirm that the SANDISK Ultra® 400 GB is working flawlessly with the Galaxy S7.
The phone formats it to exFat and it shows 366 GB of available space.
(Which is correct.)
Only thing I couln't do yet is creating two partitions and linking the second to internal storage (No1 for exFat storage and No2 for Ext4 internal-sd-extension).
Well this just won't work.
When I try the internal-sd-extension is detected but I can't use it nor can I use the exFat storage which is not detected at all.
Don't know how to do this.
But nevermind.

For something like that you may need to use something like gparted to partition it how it needs to be for that to work, but I don't know
