[Q] does the t989 support a class 10 memory card?

So does the t989 support a class 10 memory card, or am I stuck using a class 6 like every other device I've owned?

Yes, class 10 memory cards work. I have this card in my phone now - http://www.newegg.com/Product/Product.aspx?Item=N82E16820220546
EDIT: But I will say that you will not get 10MB/s copying files to the card over USB. I only get about 4-5MB/s, but if I plug the microsd card directly to a memory card reader I do get about 10-11MB/s

then your computer USB port is USB v1 or or needs better driver to run as a USB port v2
you get even faster speed on a USB port v3

Do you actually notice a difference on your phone though?

My memory card reader and phone are both plugged to the same USB hub (front of my case). Also, plugging it into my USB 3.0 ports don't increase the speed either. Its not that big of a deal for me, but just throwing it out there.

PNY makes a really good one

Class 10
I hear Class 10 is ideal for the high DSLR cameras so Class 6 and 4 is pretty much what you need if you're looking for only storage.
I was always considering something else besides Class 10 but it seems to make sense since the T989 has 1080p video recording (and 8MP photos), anyone with Class 10s in their flash memory slot?

Wow, looks like you know a lot about computers.. First of all its called USB 3.0. Second, no phone at all supports USB 3, third is that no computer has USB 1 unless it was made in the 90's.

Some computers will have USB 1. For example, I have a logitech G11 keyboard. If I plug in my phone to one of the two usb slots on my keyboard, then it's USB 1. You may think he doesn't know much about computers, but we KNOW you don't know much about manners.

And yes, Class 10 is supported. I own an A-DATA 32gb card and the speeds are fantastic!
I bought it also based on the info I read from this sticky:
http://forum.xda-developers.com/showthread.php?t=1338868
A little search on the forums can go a long way!

I have been using my class 10 since I got the phone. Works for me with no problems at all.

I just got the new sd card.PATRIOT 16 GB class 10.

Samsung new UHS-1 series microSD for LTE phones

Samsung's memory cards were updated late Wednesday with large-scale production one of the world's fastest microSD cards. The new 16GB microSDHC card runs at the same UHS-1 (Ultra High Speed-1) spec normally used for the latest full-size SD cards, giving it performance that would previously have been reserved for pro memory for DSLRs and video cameras. Sequential read speeds peak at about 80MB per second, or roughly four times the 21MB of regular microSD cards.
The storage is ostensibly meant for LTE-capable smartphones and tablets, where flash memory speed could bottleneck the connection. It should nonetheless be useful for cameras that take microSD storage and support UHS-1. Samsung reached the density through a combination of its more recent 20-nanometer manufacturing process to build 64-gigabit (8GB) chip layers as well as a toggle DDR2 interface that can saturate the newly available bandwidth.
Release schedules and prices weren't given out, although mass production usually precedes a launch within a few months or less.

We need to know which file system those cards are formated in order to reach the high speed. If it is exFAT, then those numbers are pointless as all the smart phone storage currently formatted in FAT32 which is much slower.

Awesome, now just tell me how to fit one in my One X.

They have 32gb built in Rom, for me its smart move as I have had probs with sd slots on previous phones

sorry guys I ran thru and posted at all the lte phones I knew off top of my head , I thought only the nexus didn't have an sd card ..
so how will flashing roms via recovery and such work here just never wipe the ext-sd ?

It's a proper partition as opposed to a virtual partition like transformer prime. Wipe is fine, just don't tell it to wipe sd partition.
Only issue at the moment is that recovery doesn't have UMS, so if you don't have a booting OS and don't have backup/rom on phone then you are in a bit of a pickle Will be resolved when recoveries get more advanced. Very early days.

Storage and SD class questions

When installing apps on the phone, are they installed in the hidden system partition, or on the internal SD card section?
Considering I would use the external SD card mainly for nandroid backups, pictures and videos – both captured by the phone itself, do I need a class 10 card or would a class 4 do?
Thank you.

To start with the internal SD card and the system partition are the same storage, just partitioned and both of them are accessible.
The application apk files are stored in the system partition while the InternalSD is used for user app data. You can store your stuff there too but try to leave a little memory free for your phone to use it without problems.
Secondly, I had an 8Gb Class4 Sandisk before, used it for months without any problem with regular use.
I am using a 16 Gb Class10 SanDisk now, and if you want more storage and use heavy files, like heavy high definition videos and high definition games, you should get a Class10, the read speed is noticeably better.
On side note, each nandroid backup is about 1.8Gb in size so storing them on SD card would be better

Since I am one of those heavy backup guys I am going for a 32GB one.
One this I thought about, I can imagine the card is limited by its reader, any idea if the GRAND even has a class 10 reader, seems like the spiritual father of the grand - the S# has only a class 6 one.

I agree. Most phone's support all class of card but they are limited by their reader. But I don't know which reader is in grand but it definitely supports class 10 cards as I'm myself using it and don't really know how to check it on phones.

You get a decent idea of write speed, it's almost twice of the minimum set for any clas 10 card (10MB/s), so safe to assume that it's working good

Always use class 10 mc..

SanDisk Ultra SDHC UHS-I (Class 10) Card 16GB with a boosted read-ahead speed of 4096kb

Well I bought a Transcend 32GB class 10 card, tests are similar to your tiny bit higher, but reads seems way too high (around 300MB/s) maybe SD booster is measuring the internal SD, anyhow thanks for your help!

Which SDCard?

Not having a Sony before, do they have issues with certain brands/speeds, I know the Motorola phones used to be picky about which cards they would accept, can anyone recommend a decent card type for the Z3c please.

I'm using sandisk uhs-i 64 gb card in my xperia z ultra. No problems so far.

Good news, I've just ordered the SanDisk SDSDQU-064G-FFP Ultra 64 GB Class 10 Micro SD Card

I have used the same 64GB card in my Galaxy Note and Xperia Z and never had any problems, so you should be good to go!:good:

Used both 64 and 128gb sandisks on z1c with out issue.
Other then the fact any android 4.4.4 devices deny any non system apps write access to the sd (until root+xposed at the very least is applied.)

Is somebody able to confirm if external SDcard encryption is an option in the settings?

Inserted a Samsung 32GB Class 10, no issues.

Samsung 64GB EVO here. No problem.

Does anyone know the fastest card that this phone supports? I am willing to shell out the cash for one of those UHS cards like the SanDisk extreme pro or extreme plus, but only if this phone will be able to take advantage of the speed.

Faster card will help with 4k video recording if nothing else.

Would anyone mind testing the Sandisk Extreme Plus and Extreme Pro MicroSD card please?
I'll probably buy the Plus next week but would be great if someone had one already and didn't mind testing before me. Otherwise, will post my results at the end of next week.

Tab S 8.4 Max Memory Card Size

Well when it first came out (the tab s 8.4) only 128gb micro SD cards were the largest available.
So my question, can we assume that any micro SD XC 1 card will work fine in this tablet?
I ask because I stumbled upon this 200GB card now available.
http://www.amazon.com/SanDisk-micro..._UL160_SR160,160_&refRID=00EQDPJ5PMBTHB0A266Q
Or is this tabs card slot locked some how to only except up to 128GB max?

If the Tabs S works with XC 1 cards have an 128gb one and it works fine, I suppose an 200gb that is XC 1 should work as well as an guess.

I'm using Sandisk 32 GB and the transfer speed sucks... avg around 10mb/s when transfering files from my tablet to PC via USB cable.

Get the biggest card you can afford, a 64gb or 128gb, I only ever buy Samsung flash cards for years for my camera`s phones and tablets, I all do a exhaustive error test when i get them and i have never found an error or had one fail, So i don't have any experience of other brands but Sandisk is a good brand.
I just bought an Samsung 128GB Evo+ the other day for £36 and i am just about finishing the error testing, It is showing a write speed of 20.46mb/s and a read speed of 63.56mb/s these are just basic number using an USB 3.0 card reader on my notebook, I have an crystal disk mark test results if you want to see them.
My T800 10.5" has formated my Samsung 128GB EVO+ as ExFat file system, benchmarks should really be run with the card in your Tab S for real world results.
John.

Thanks! Time to test out Samsung sd cards then.

Highly recommended Samsung evo cards. Its all I use now. Good value for money.

A few speed test reviews on Amazon say the Samsung 128GB EVO+ is not very good as the 4K file write speed is very low, But i dont write anything that small, even ebook files or mp3 files are hundreds of mb/s
Below are benchmark run on my Notebook using an USB 3.0 card reader.

John.

I personally never had any issues with Sandisk. I have really old Sandisk cards laying around (64mb) and they still work fine.
I'm actually scared to try a different brand with the good luck I have had with Sandisk.

I am in the US but this is what I am using now. The 32gig one. Go with the biggest you can afford to be honest. Make sure its class 10. Always buy from an official Sandisk seller on Amazon to avoid fakes.
