Hi all,
I am about to switch from Prophet to Polaris. One very annoying problem of the Prophet is the extremely slow USB transfer rate (I guess it supports USB 1.1 only) - I have to transfer large stuff to the memory card directly.
How does the Polaris perform in this respect?
Polaris work on usb 2.0.
Bye
If you are still interested (last weekend I had to transfer few files):
Tested with a 1GB Sandisk (was in package)
~0,5MB/s USB (Vista 64-Bit, 333MB moviefile transferred in 10:47min)
~100kb/s Bluetooth (Macbook OsX 10.4, 3MB moviefile)
so keep your cardreader
(Maybe the Sandisk isn't the fastest, but I believe that the phone restricts the transferrate. So USB 2.0 is just a marketing trick)

Damn, too bad So this means you cannot practically use your device as a USB stick with tools like CardExport...

If you buy a MicroSD card from Sandisk you get a USB cardreader as well.
This is the fastest method to transfer large files from a PC to your memory card.

That's exactly what I did an hour ago Still, it would have been much easier if I could transfer the data directly through the device...
I am about ready to buy a 16 GB class 10 micro sdhc for my Nexus One. Any ideas if this is a good card. Will it be totally compatible? And will I be able to transfer at the advertised speed? Does anyone have one of these?
http://www.newegg.com/Product/Product.aspx?Item=N82E16820139121&Tpk=SDC10/16GB
I think a class 6 is enough. Don't see a need for a class 10.
If HD recording ever gets adapted....or divx playback I'm sure the extra speed wouldn't hurt. The question is whether or not to nexus 1 will utilize it.
My class 6 micro sdhc card is only transferring at 2 MB/s through the data cable from phone to computer and vice versa. Either my card is taking a **** or something is wrong, it's definitely not 6 MB's.
So if I can pick up a class 10 micro sdhc and actually being able to copy music onto my sd card mounted in my phone at 10 MB/s I would be really pleased.
I just pulled the my micro sd card out of the phone and plugged it into a micro sdhc to usb adapter, and I transferred music onto the card through the adapter and it transferred at 6 MB/s no problem. So there is nothing wrong with my micro sd card. WTF Has it always been this way.
What I mean is: while the card is in the nexus and when you transfer music to the phone through the data cable, is the nexus only able to transfer at 2 MB/s? Through the Data Cable?

Yup... I've noticed this too. It was the same on my G1. The card is capable of 6mb/s but the phone can only do 2mb/s through the usb...

That really is a bummer, I don't know why in the hell I haven't noticed this before. It really doesnt matter to me how fast my sdcard card is then. Because I never ever remove it from my phone. So a class 2 is pretty much all you need because that is the only speed the phone will ever transfer at.

Unless you're rooted and run Apps2SD... but yeah, I'm unrooted on my N1 and plan on staying that way and I don't understand it either. Maybe there's a way to speed it up with a software update?

Let me get this right. You have your micro sdhc card in your phone. Then you plug the the usb data cable into your phone, then you mount the phone to your computer by the pull down menu on your phone, then you can transfer music to your sdcard at 5.6 MB/s? Are you sure about that? And you have to be able to transfer music off of your phone onto your computer at the same speed I assume.
The reason I am mentioning all this is I partition my sdcard to 3 partions fat32, ext3, and swap. So another words I had to transfer everything off of my sdcard, and transfer it back on after you created the partitions. And if you have 6 gigs of music this can take a very long time. Then I formatted my sdcard again for 1 partition and had to do everything again. At 2 MB/s that is a very long wait.
I guess I could of just pulled the sdcard from the phone and plugged it into my adapter and transferred at 6.0 MB/s. This sucks you would imagine the nexus could do this np.
It's amazing you can do it at 5.6 MB/s to your phone. Maybe you got a better version of the Nexus than I did?
Don't forget, there are two sides to the issue, the phone side and the computer side. Perhaps you could try another computer? I average 5.5MB/s from my Linux workstation.
Are you going through an old USB hub or direct to the computers ports?

Direct to the computer ports, and I am running windows 7, maybe I should try my ubuntu pc.
The phone's USB interface might be the limiting factor; when the phone is communicating directly with the SD card, it may be able to use its full potential. This would matter when you're recording video or using Apps2SD. Meaning that class 6 cards aren't necessarily pointless.
Also note that class 6 means 6 MB/s write speed, not read speed (as has been kind of said above - just waned to make it clear) - if you're reading it at 6 MB/s, that doesn't necessarily mean it's working right.
I don't have one to test with, sadly.
What I wanna know is where are the 32Gb Micro SDHC cards??
I have a 16GB a-data micro SDHC transferring via usb at speeds between 2-3MB/s
when i put the card in a card reader instead of the phone, xfer speeds are between 5 and 8MB/s
I'll try copying files to SD via wifi and bluetooth. if either of those are faster than 2-3MB/s, then the usb may be the bottleneck.
Are you guys benchmarking , or just going by screen stats ?
dang i didn't know they even made class 10.... I bought a class 2 16gb when they first came out, it just died actually so i'm waiting for sandisk to replace it. I've considered a class 6 but i don't see the point with 32gb cards coming out soon.
I've seen pre orders for late april on the 32gb's. other then that you can get one now if you import it from asia.
I am just wondering exactly what speed the Nexus One is capable of transferring at? Cause I can see alot of people are having the same problem as I am having with higher class sd cards. I know for a fact my class 6 sd can transfer at 6 MB/s and it does when its not in my Nexus One, so it's either the Nexus or the Data Cable that is eating the other 4 MB/s, cause I am only cable of transferring at 2 MB/s and no more.
Now when I talk about transferring I am solely talking about transferring music or data off of my Nexus to my computer and vice versa. I want to think it's just my Data Cable. But I wish I had this answer, I will today for sure.
Now is there a low speed Data Cable, maybe that is what Google sent me a low speed one, and maybe this 1 penny high speed data cable might solve me some problems.

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.

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
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
