Kingston Class 10 Micro SDHC Yes or No

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?

i get a steady 5.6...

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.

SDHC card and connecting to car stereo (problems)

1.) I bought a 16GB SD card (Patriot) at Microcenter last week. Everything was fine until last night I noticed my program were blank. I then see the card is not mounted, and will not mount period. I removed the card and put it in my laptop where I could see the files. I did notice the card was locked read only, even though the card adapter was clearly not set for it.
Is there a set list of SDHC cards that can only be used? Do I need a certain speed card? Any ideas why this card refuses to mount suddenly? I can't even format it in either the phone or my laptop.
2.) I have a car stereo with AUX port I used for years with ipod. Plugged in the phone to play music and it worked fine for a day or so, then either my speakers (all 4) have fried, or the stereo itself is fried. Radio and CD both produce crackling static, then silence. The timing seems odd, so it does seem that connecting the phone to play music damaged it? Ideas or thoughts anyone?
Sent from my SAMSUNG-SGH-I997 using XDA App
Edit: About the SDHC card, I have put it in the laptop with several adapters making sure the lock tab is not pushed down. Even tried the tape method. Card is locked, and nothing seems to unlock it. Personal data such as photos (I think of just the cat) put there is an Excel sheet that has invoicing information for my work, as such I have to delete this before returning. Would a magnet work? I guess in the end not too critical, but still.
Edit #2: Found someone else over at Android Central who had the same exact problem with the same exact card, the Patriot 16GB SDHC class 4 found at Microcenter. Suffice to say I am just going to exchange it for a SanDisk. So does anyone have an idea how I can erase the existing data? Would using something like Ubuntu do the trick?

Compatible/Incompatible MicroSD/SD Cards

Had some problems trying SD cards and MicroSD cards for the Infinity/Prime docks/tablet. Thought I would share them so others could also update and post their compatibility issues.
PNY 16GB (MicroSD) / 32GB (SD) Pro-Elite: Status: Incompatible: Formated with Fat32/NTFS and exFAT. All three had no problems reading from the card however writing any files completely locked the tablet up at the 90MB mark causing it to force reboot. Tried 2 cards purchased from Best Buy (16GB and 32GB) on both my Prime and Infinity tablets/docks both had these issues. Card is rated for 35MB write however I found no circumstance using my PC to copy files to where I got over 10-11MB/sec. Read sat at around 21MB/sec.
Sandisk Ultra 32GB (MicroSD, (Docked with MicroSD Adapter)): Status: Compatible: Formated with Fat32/NTFS and exFAT. All three work great reading and writing on the tablet. Writes were a steady 22MB+, Reads just as good. I assume once the I/O bottleneck is fixed this will improve, as it sits on the PC I get around 30-40MB write, 55+MB read (burst). Writing a 3GB file ~ 15-20MB wite.
I should mention I was using a USB 3.0 card reader to read/write when testing on the PC.
Please update this thread with your cards you have tried so others like me will not have to return to BestBuy 3 times to finally get a compatible card.
Thanks!

Might the incompatibility be caused by card class?

It is possible however I have not tried any other cards from any other brands.
The PNY is listed as: SDHC Class 10, UHS-1
The SanDisk is listed as: SDHC Class 10 UHS-1 so they seem to be exactly the same class.

I also bought Sandisk Ultra 32GB Class 10 micro sd to be used on my phone Xperia Mini, i find my phone to be very slow, does this means that my phone is incompatible with this card.

I do not know how you formatted it, and which filesystem(s) your phone supports. I'd set out my question in the Experia forum(s).

I bought a 64GB Samsung microSDXC UHS-I card pro class 10
http://www.amazon.com/Samsung-micro-UHS-1-Class-Galaxy/dp/B00AK31M3G
And it works great, havent had a problem with it, I tested it through a sd card slot with sd card adapter and I got a constant 16-17 mb/s write speed with files bigger than 5 gb. I also tried formatting in exFAT and NTFS, and both work.
I hope this clears up some doubts about UHS-I cards. Or at least doubts about this card.

I also bought the SanDisk Ultra 32GB Class 10 microSDHC UHS-I Memory Card includes an SD adapter and use that on my TF700 without any issues at all.
I have connected it both directly in the SD slot and also via the adaptor via the OTG dongle into the USB slot as a 2nd memory card.
Both have worked reall well, so am surprised the card is not working for some.

I just got my SanDisk Ultra 64GB microSDXC Class 10 UHS-1 from amazon today, worked out of the package and then reformated to exFAT and worked also. Haven't do much else with it but so far so good.

For an SD card I picked up a Polaroid 64GB SDXC Class 10 UHS-1 for $32 a couple weeks ago (was going to get a SanDisk as well but for $20 off figured I'd give it a shot and it had some nice write/read speeds), worked out of the box on my dock and did the formats. Rght now I've got it filled up with 60gb of movies for an upcoming trip and everything seems to be working fine as well.

Did you try that Polaroid card in the dock only or does it both work in the dock and the tablet. I might just buy 2 of these and be done with it.

I am currently using 64G Samsung in my TF700t. It works perfectly fine with the original format extFAT. I reformated it with FAT32 and Ext4 for Data2SD. I don't have any problem so far.

I got the Samsung UHS-1 from Amazon as well, tested it and I am very happy with this investment of $65. Now when I do a TWRP backup, it finishes in 212 seconds for 1850 MB, averaging 8.7MB per second. When I copy files over from a PC, using the Silicon Power USB 3.0 card reader which is UHS-1 compatible, I constant have a write speed of 14.5 MB/s and the Read speed is over 27 MB/s.
They advertise to have a read speed of 70 and write speed of 20 though.

Your pc probably just cant go any faster .
I'm using two 64gb SanDisk SDXC class 10 in NTFS format, and two Medion (aldi) 32 gb class 6 in NTFS.
All four work perfectly well. But they are only used for storing media.

I use SanDisk Mobile Ultra 32GB UHS card as my Data2SD card. Formatted with FAT32 and ext2. NTFS works fine too. But be aware that ext 4 with Data2SD on this card might cause some trouble. I had a lot of freezes and random reboots with Data2SD as long as I used ext4 format. Now I formatted to ext2 and so far I had no freezes nor reboots.

Comp Addable!

Memory card Help

People im looking to buy a 64 gb mem card for the s4 but would a Micro SD XC type work or just a micro sd?
Also should i be wary when buying from ebay or just get it from amazon for a couple quid more??
Based in the UK - if that helps
cheers, all

Yes Micro SDXC will work on the galaxy s4, it has somekind of extension which i forget what is it. If u want u can change or reformat the extension to fat32 so your s4 can read it..

Do not buy off ebay. Lots of counterfeit and scam products. Buy somewhere that you can be sure of what you are getting. Also, some people are reporting problems with SanDisk - mine works fine, but there are enough reports that maybe the new ones have issues.
I am not sure what format the phone puts on the card. But most of the time you can just pop it in the phone and use it. If the phone doesn't recognize it, it will ask you to format. Exfat has the advantage of working with files bigger then 2GB, but unless you are copying movies (that have not been resized) then this should not be an issue. Most phones do NOT support exFat, but unless you are swapping the card between devices, this should not be an issue either.
So, I would just pop the card in the phone and start using it. If you don't usually remove it, you could format it on the phone first, just for kicks (I never do unless it asks me) and you should be good to go. Windows handles Fat32 and ExFat, so there is no real issue with the computer.
HTH!

i had issues with a sandisk 64gb microsd on 2 different s4's. these were purchased from Amazon so they were legit.
switched to a samsung microsd 64gb, also bought via amazon, and it just plain works. and is faster on the phone - mounting or unmounting happens instantly. the sandisk took time. etc...

Taken off the Meenova website:
Due to hardware and software limitations of many Android devices -- especially older ones, compatibility with devices not listed here can't be guaranteed.
Samsung: Galaxy S5, S4, S3, S2, S4 Active, Note 3, Note 2, Note, Mega; Galaxy Tab S
Judging from that I would say you'd be perfectly fine, and common sense was telling me before looking it up that you'd be fine.
I can't think of a single modern device that doesn't support OTG, and all OTG devices pretty much work the same.
The only question is whether it supports NTFS or not, but hey... Just format the MicroSD card with FAT32 and you won't have any worries at all.
My recommendation: Go for it :highfive:

It should work for storage sizes up to 2TB. If the S6 can't power a HD over OTG cable, you can get a special OTG cable that lets you add the necessary power from another source.

Hi,
Just a suggestion here, instead of doing it manually by using card and card reader you can do it on the fly you can use sidesync app or smart switch or any other app.
Just install on both phones fire it up on both phones and choose send. It will show you a list of all the content by type and category! Choose whatever you want move and hit send and now on the receiving phone click receive and it'll either create or ask you to join a network u can connect it on send phone by choosing the receiving phone in the "found connection within the app. You will see it start sending files and on the other they'll start coming in. I it is pretty fast too. I have about 40 gigs on my extra and around 20 in internal loads of mp3 which didn't take long. you can check it out. there's even an app by Jio called Jio Switch which does the same. No more downtime and no attachments needed?.

Works!!! I use mine through a SANDISK Wireless USB Flashdrive-(it has a micro-SD slot) out through an OTG & it has been performing flawlessly! You should have no problems with it, but I would make sure it's formated to ExFat or ExFat32 just to make sure it reads....
