I have heard reports that you can't use a card > 16Gb in the tablet but that's unconfirmed AFAIK.
I've also heard rumours that the keyboard's full-size SD card slot will take SDXC format cards which supports >32Gb capacity but again I've seen no confirmation of that.
I am snapping this up as soon as it's released here.
Questions on the storage:
1-As mentioned above, is this confirmed that the tablet microSD won't accept anything larger than 8GB?
2- If i get the dock and say I have a 16gb microsd card in the tablet and 32gb sd card in the dock, i should be able to access BOTH of these from the tablet (while docked) correct? So theoretically, I would have 16GB-built in flash on tablet + 16GB microsd card on tablet + 32GB SD card in dock = 64GB?
3-I just want to find out if by docking the tablet, the tablet storage just acts like another drive?
Thanks

1- Even though I have the original manual here as a pdf, there's no info on what is the maximum size of SD card in the tablet slot.
2- I'm 99% sure that it's like that. Everything else would be stupid because many android applications store data on the (tablet) sd card.
3- yes, quite sure it does.
As a plus, you can use the USB 2.0 ports to add external hard drives.
Quote from manual:
USB Port (2.0)
The USB (Universal Serial Bus) is compatible with USB 2.0 or USB 1.1 devices such as keyboards, pointing devices, flash disk drive and hard disk drives.

There's a way to use USB host without the dock? I don't want to buy the keyboard because i've already got a 13" notebook for mobility, i just need a tablet but the USB host is necessary for me.

In that case, I can't wait to get this tablet what a great concept, best of both worlds. No need to buy a case, just shut the lid and you can carry it on travel without worrying too much just like a laptop, with all the various expandability options, no need to worry about HDD space either.
When combined with dock, it actually has 2 3.5mm sockets, which means I can use 1 device and myself and my wife can watch the same thing with 2 headphones and not worry about viewing angles thanks to the IPS screen...
So long as the 16GB tablet+dock comes in at around $500 or less, I am good...!

Did you by any chance find out what is the maximum capacity of the microSD card that can be used in the tablet?
I have a 16Gb class 10 installed and working perfect. I'm just thinking to purchase one of 64Gb and I'm not sure it will work.

There is no rated max capacity, I've see people who put 128GB cards in there (NTFS formatted) that work fine.

That's great news. I'll try to find a good deal on a 64Gb card and use it with my Transformer

Does anyone know if we can connect an external USB drive to the TF101 without the dock? Thanks.

[Q] Help! GT7+ transfer data speed via USB very slow

My GT7+ took more than 1 hour to transfer 1GB data of Steet Fighter!
What is your data transfer speed?
You guys have any ideas?

As far as I can tell it's due to the MTP protocol. It transfers at a slower rate than the USB Mass Storage mode. Currently I can't seem to find a way to enable Mass Storage mode on the Tab though.

All HC tablets using MTP are that slow. This is not a 7+ specific issue.

The solution would be Mass Storage mode, the problem is Samsung doesn't seem to have enabled it.

Not just HC tablets. My Atrix is slow as sin when using MTP and same with my SGSII. For speed I always resort to Mass Storage Mode.

Even with MTP, 1 hour for 1GB isn't normal. Guessing the OP hit "yes" when MTP asked if he wanted to convert it.
My tip? Fast SDHC card + SD connection kit, ignore the internal card for things you don't need on there forever (like video)

what about wifi transfer using estrongs or something like that

i juz got a 7.0 plus and my file transfers are blazing fast... 2.2gb in less than 8 mins..
I dont have kies installed or any other software, i just connect it to my computer using usb and it comes up as a portable media player GT-P6210.
When i open the folder it shows all the available folders and i just drag and drop files with ease...

That is by no means fast. 2048MB in 480 seconds means just slightly above 4MB/s. That's basically what you have to do minimum to qualify as a class 4 SD card, way less than half what's needed to qualify as a class 10, and 1/7-1/4 of what you'll actually be getting if you have a fast USB drive/card connected directly as the top-of-the-line stuff does 20-30MB/s on large files.

For MTP protocol, that's actually pretty fast. My Core 2 Duo computer that I have at work copies over MTP at about 1-2MB/s, if I need stuff on my device I stick with WiFi based transfers from my NAS or plug in my 32GB card to the computer.

Indeed it is, I was just pointing out that it's very slow compared to transferring to a flash drive or card in a card reader with UMS

Slow file transfer when using mass storage mode

I am using SGS2 with Restruction ROM with Fluxi Kernel and transferring files to external SD (Samsung Class 10) through mass storage mode and it is extremely slow (less than 1MB/s even when large files). Took out the card and tested with card reader, it can write more than 20MB/s.

The speed is limited by weakest point in the system. Check USB cable, port and other end device, too.

Previously I got no problem with Gingerbread (CheckROM). Same port, same cable.

Best SanDisk sdcard for PRO 12.2

Hello, it turns out that 128GB is out of stock in my city. Now, I have to choose a SanDisk 64GB. Is the Ultra microSDXC UHS-1 Card with Adapter (Class 10, speed up to 30MB/s 200x) the best for this device? I think I read a posting saying that the PRO 12.2 cannot take advantage of the Extreme, Extreme Plus and Extreme Pro. Is that true? If not, please let me know the model number of the recommended one. Thank you.
http://www.sandisk.com/products/memory-cards/microsd/

I just got this one
Sandisk
Class 10 (64GB) microSD, full size SD adaptor and mobile mate USB Reader

Not true. Extreme plus does run faster. I have one on order and will post a comparison to an ultra when I get it. I know it is faster because i had one in my first note pro and it performed as quickly as internal memory whereas now with the ultra that I am using in my new note pro file transfer to external microsd is slower than to internal memory.

Is this very noticeable? Given that there is a write problem with KK, is it worth to get the Extreme Plus?

Value is subjective man; you're asking someone who basically spent $1500 US on a note pro having lost his first rig in an act of stupidity. Worth it? Definitely for me. I don't like waiting for long file transfers. I'd rather have a 64 gb card that's twice as fast than a 128 gb card.
Sent from my SM-P900 using Tapatalk

Thanks. Which one do you recommend?
SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card
SanDisk Extreme microSDHC/microSDXC UHS-I Card SanDisk Extreme microSDHC/microSDXC UHS-I Card

For me write speed is critical. Both of those top out at around 50MB/s so you probably can't go wrong with either.
The one that I've ordered (and had before) is the Extreme Plus 64GB.

Ok I have to take back this statement: "it performed as quickly as internal memory"
Here's my test results utilizing two types of tests, one for approximately 125 files totalling 1.4GB (digital camera pics from a D7000) and another for a 1.9GB video file again from a D7000 camera. The files were placed on a Sandisk Extreme USB 3.0 64GB flash drive which was inserted into a USB 3.0 port. This served as the source for all test copies to the tablet/microSD cards and the source USB flash drive stayed in the same USB 3.0 slot throughout.
All times are presented in minutes and seconds.
Note Pro Internal Storage
1.9GB video file over USB 3.0: 0:40
1.9GB video file over USB 2.0: 1:24
1.4GB of photos over USB 3.0: 0:40
1.4GB of photos over USB 2.0: 1:07​
Clearly, USB 3.0 transfer speed to internal memory is faster than USB 2.0.
MicroSD - Sandisk Ultra 64GB
1.9GB video file over USB 3.0: 4:42
1.9GB video file over USB 2.0: 4:48
1.4GB of photos over USB 3.0: 4:17
1.4GB of photos over USB 2.0: 4:18
1.9GB video file using USB 3.0 card reader: 4:45 **
1.4GB of photos using USB 3.0 card reader: 4:19 **​
Clearly the write speed to this card is the limiting factor. It made little difference between USB 3.0 and USB 2.0. These measurements are not scientific, I'm merely using a stopwatch here and watching the progress bar on my Windows 7 machine.
MicroSD - Sandisk Extreme Plus 64GB
1.9GB video file over USB 3.0: 2:19
1.9GB video file over USB 2.0: 2:20
1.4GB of photos over USB 3.0: 1:47
1.4GB of photos over USB 2.0: 1:47
1.9GB video file using USB 3.0 card reader: 1:35 **
1.4GB of photos using USB 3.0 card reader: 1:18 **​This is where I eat my words. It's not as fast as the internal storage in the tablet, but in my defense it definitely is faster than the Sandisk Ultra which is a Class 10 card. Also note that using a USB 3.0 card reader did give me faster results. I'm not quite sure what's going on there.
So . . . is it worth it to go to an Extreme Plus ? It's subjective once again but for me, spending $75 vs $40 isn't a big deal to get double the speed. If i'm rushing out the door to a meeting and I need to copy a few gigs of data to my device I know what card I'd want in it .. . .
If all you're doing is loading storage up with video files for use during downtime, say movies and TV shows then either card would be fine. If you're pushing data on and off of the card more often though then perhaps the speed will make a difference for you.
** Note: USB 3.0 Card reader was plugged into the PC. This test was to confirm transfer speed to the two different types of MicroSD card themselves without interaction with the tablet at all.

Thank you very much for the tests. The results could be very useful to all of us. Good job! Why you used a usb 3.0 reader instead of inserting the card directly to the internal sdcard slot? I think the PRO 12.2 only has a usb 3.0 port. Where are the data related to usb 2.0 coming from? It would be very useful to have the data when you use the card inserted into the memory slot.

The SD Card Reader results are to show transfer to the MicroSD card when it's inserted into an SD Card Reader that's plugged into the PC not the tablet.
Sorry I didn't make that clear. I'll edit my post to mention that.
The USB 2.0 speeds are data transfer when the tablet is plugged into the PC using a USB 2.0 cable. I'm not sure if you're aware but the only difference between a microUSB 3.0 and 2.0 cable is the addition of data conductors in the USB 3.0 cable. Hard to describe but if you look at the ends of the cables the end of the MicroUSB 2.0 cable is identical to one side of the 3.0 one. Charging is accomplished using this edge of the 3.0 cable so charging speed is no different between the two types but the additional conductors for data transfer yield increased transfer speeds on 3.0.

Sorry I am a bit confused. Where is the test results of using the SD card slot?

They are the ones without the asterisks.

Thanks. But those without the asterisks are either usb 2.0 or usb 3.0. I am looking for data related to the Ultra and Extreme PRO inserted into the sdcard rather than usb slot. Am I missing something?

I'm not sure where the confusion lies. Hopefully what I describe below will clear things up for you. All of the information is right there with headings and all.
Its broken up to 3 sections:
Section 1 - Note Pro Internal Storage: describes copying either 1.9GB single movie file or 1.4GB worth of photos to the internal memory of the tablet (not MicroSD) . . . utilizing EITHER a USB 3.0 cable connected to the computer, OR a USB 2.0 cable connected to the computer.
Section 2 - Sandisk Ultra 64GB: describes copying either 1.9GB single movie file or 1.4GB worth of photos to Sandisk Ultra 64GB card while its inserted in the tablet . . . utilizing EITHER a USB 3.0 cable connected to the computer, OR a USB 2.0 cable connected to the computer. . .
The card reader results (which are now identified with asterisks) are merely there to show what the file transfer times are IF THE CARD IS IN YOUR COMPUTER as opposed to being in the tablet. I included the card reader results to show you the maximum write speed of the card using the same test . . taking the tablet completely out of the equation. I suppose this is where you're getting confused because you're seeing the phrase "card reader" and thinking that I'm plugging a reader into the USB port of the tablet . . I'm not . . Again the purpose of testing write speed to the microSD cards in a card reader that's plugged into the PC is to set the benchmark for how fast the memory card really is without the tablet even being a factor.
Section 3 is the same thing as section 2 except for the Extreme Plus . . .
Again, all times are WRITE times . . either to the stock internal memory of the tablet or two the microsd card which is either inside the tablet or in an external card reader connected to the PC (no tablet involved).
By reviewing the times you can clearly draw a few conclusions:
1) that if you buy a Sandisk Ultra then the memory is slow enough to completely negate the need for a USB 3.0 cable when copying data to the card from any external source (clearly no matter what cable is used the times are the same) and
2) that the Extreme Plus is about twice as fast as the Ultra for write speed.
3) that the write speed for the tablet's internal memory is faster than the extreme plus which is currently one of the fastest available microSD cards

Can GS6 Handle 1 TB External HDD?

I have used external hard drive before with my note 3 but it's only 150GB. Now with S6 having no expandable SD card, I'm thinking I'd keep an external hard drive handy. I know it supports USB OTG on the get go but can I it run 1 TB HDD without extra power source? I think this is better than buying a 64 GB model with the same price of 32 GB model and 1TB HDD.
or do you think I should go with the 64 GB model?

Did you have 1TB of storage on your previous phone with SD? If not, why do you need the hassle now? Why not get a MicroSD adapter that is a fewe $ and still use your MicroSD?
To naswer your wuestion - it will not handle a device with that much power draw.

Hard to say, but I would first start with upgrading your Macbooks drive instead of looking at solutions like connecting a 1TB drive to a phone.
An extreme solution would be to get get proper cables and use a powerbank to power the drive and have it working on the phone, still.

It's not the size drive that's the issue, its the type of drive you connect. A flash drive is one thing, bit don't think about hooking up a 2.5" mechanical external hard drive. Even if it worked, your battery would die in no time.
Sent from my "bigger is smaller" LG G3

Let me break it down.
Note 3 USB OTG output current: 900mA
Note 2 USB OTG output current: 500mA
Note 4 USB OTG output current: 600mA
S4 USB OTG output current: 500mA
HTC m7 USB OTG output current: 300mA
HTC m8 USB OTG output current: 500mA
So, maybe, maybe not. Note 3 can run every drive I've tried except the power hungry 4TB Seagate Backup Plus Fast.
If you want to measure your drive and find out the current draw, just buy the inexpensive CHARGER Doctor.
Also, the S6 will probably have 600mA output, so it most likely can handle some drives, but you'll need to measure to be sure. I'll be testing an S6 soon to verify output current.
