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 just got an Epic 4G and while the 16GB microsd card is plenty of space for most stuff, once I start putting alot of converted movies on there, it will disappear fast. Now, I had another 16GB microsd card, along with a class 6 8GB card and a 4GB card, all micro-sd. Is there any way at all to plug something into the micro-usb port on the top of the Epic and have a micro-sd reader at the other end and then have the phone be able to mount the extra/2nd micro-sd card so I can then play movies/etc from there rather than having to constantly pull off the back cover and swap cards?

This seems pretty impossible, i looked up some info on the subject and
well... all results were negative
how hard is it really to swap out that little card on the back though! i mean come on, years ago we had to swap out vcr tapes for ONE movie!

Leads me to believe it would be kernal based. If you has a female usb to microusb male and a usb micro reader, as long as the kernal had support I don't see why it couldn't be done.. but the devs would need to confirm or deny.

Go with the 500GB drive. The ports on the Transformer are USB 2.0, so you won't see any speed benefit from having a SSD connected.
However, if you want something that you don't have to plug into a USB port, the SD card slot will support SDXC cards. You can add an additional 64GB or 128GB SDXC card for around the same price as a comparable SSD.
So there would be no benefit to the SSD?
Plus 500GB does sounds nice
Its a go flex they any good ?

There are.
The whole "no moving parts" thing is a really good benefit.
I take my tf+dock to work everyday, i dont turn it off. I would be forced to turn it of if it had a standard drive in there.
And are you going to have 500gb of data?
Close to it I have allot of music movies and then there's the data for my university papers etc
I may not fill up 500 but I know I will probably fill up 320 so its wether I condense things down and get the SSD benefits or deal with the battery drain inherent with the HDD and the possible failure of the HDD later on
Also the HDD i'm looking at is a sea gate go flex 2.5" portable would this be the best brand or can someone recommend anything better HDD wise?
Sent from my GT540RR using XDA App
An SSD's performance lies in being able to read multiple files at the sames time at high speeds.
Personally i feel SSD's real speed is only put to use as an internal disk on your laptop/desktop to boot/operate faster.
For an external multimedia storage drive I recommend going with a 500gb 7200 rpm drive.
Obviously you can disconnect it after you are done using it. Power consumption difference will be around 0.5-2W average for SSD and 0.7-2.5W for an external drive.
But to save battery and money go with the 500gb drive, briefly connect it and transfer data you wish to access onto your internal memory and use it
You will actually get the best battery life possible by storing your files to a SDXC card (0.06W to 0.3W), but of course like the SSD you're limited by meager storage space compared to a regular hard drive.
All good points I think I will go for the 500 just hope it doesn't screw up also do any of the portable hard drives have spin down or are they constantly spun up ?
Sent from my GT540RR using XDA App
I might be late but if you haven't bought yet, I'd vote for a both.
Buy a smaller SSD/SDXC/SDHC with a reasonable amount of space for files you will carry around all the times.
Get a HDD for storing really large files like movies which you'd need once in a while.
When not powered up, HDDs can take a lot of shock with no damage . Get the 500gb.
i would also go with the 500gb
Ha ha Nibras good to see you however I probably can't afford both
I think the 500GB is the right choice now for a on off switch between the port and cable
Sent from my GT540 RSpec using XDA App
If you can afford a 64gb SSD disk and external chassis, you can probably afford an external 2.5" 500gb disk and a 32gb SD-card.
You should get the SSD and not the HDD. Lower power consumption, no moving parts, all around solid performing. I have a OCZ Vertex 3 120gb SSD and you couldn't pay me to use a HDD for my external enclosure. Swapping between my desktop, laptop and TF is easy squeezy. No heat generated because of no moving parts. SSD is definitely your best bet. If your still in doubt, there are a ton of reviews on the Vertex 3 all over the internet and that it outperforms better than any other drive on the market today.
Cheers...
I love the idea of ssd but hate the price for a decent size and I will fill up most of the five hundred gigabit maybe in future a small ssd inside the dock but too start with price wise and what people are saying hdd is the winner

I wasn't suggesting 64GB SSD and 500GB HDD. Like the below quote suggests, I was suggesting a somewhat smaller HDD and SDD. A 500GB or so HDD and a 32GB or so SSD.

That's true. I hate how expensive they are.
If Internet is cheap where you live, you can move the large files to cloud as well. Or, store then in a network drive at home.
I think you answered your own question if you have enough files to fill up a 500GB drive that you can actually put to practical use most of the time. You'd just be disapointed having something smaller no matter how fast or trendy if you had to spend lot of time moving stuff around all the time.
I'm with an earlier poster that thinks a SSD is better used as a boot drive for a device to get everything up and running fast and to put your page file on for quicker memory management access also.
Thankyou to everyone who helped me with this im now the proud owner of a transformer and a seagate 500gb 2.5" hdd and hdmi cable and 16gb class 10 sd card all for under 1000nzd yay
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

Thank you very much for the excellent tests!
I've trying to look for these products although I'm not sure if they exist or not.
1) A MicroSD extension cable which simply uses a ribbon cable to extend the port, ideal is you want to use a case which for a phone which has a removable back.
2) An SD card which can essentially hold 2 MicroSD cards within it. A standard SD card adapter usually holds only 1 MicroSD card although I personally their is enough for 2 cards, I was wondering does it exist ?
If these products are out their, I would be grateful if you could provide details on how I can purchase them. I am a UK resident so would shopping be available. Thank You

Why do you need this cable? If your phone has a slot for 1(!) micro sd card you will never be able to mount 2 sd cards as the device can't handle it!!! If you need more space just go for a bigger micro sd card
