(Surprised)
You serious? I have the same card running on my Note 3, I'm definitely dumping SM-N9005 for Xperia Z2 if it's true.
Really appreciate it if you can show a long bench screenshot.

Sorry, what is long bench?
I don't think it's anything extraordinary for new phones to support UHS-I.

My meaning of long bench means:
Downloading A1 SD Bench or SD Card Tester to do a Benchmark.
A1 Bench (Long Bench)
SD Card Tester (To set file size to maybe 1000MB or 2000MB)
Anyways, Galaxy S5 doesn't support UHS-I Speed.
And I don't get what you mean by saying that, you don't think it's anything extraordinary for new phones to support UHS-I.
Quoted from (showthread.php?t=2708665)
Of course to say, All UHS-I cards are backward compatible. If your device doesn't supports UHS-I, It will downgrade itself to Class 10.
So, my question on the title is that, does Z2 support uhs-i speed. I'm not talking about if the phone supports the card.
Really sorry if I sound rude. I'm just trying to make things clearer.
My apologies for not giving enough information and background when I ask this question.

Thanks for the clarification.
In that case, I would say I don't know if it supports UHS-I speed. It certainly supports the card though.
As for benchmarks, I can't seem to get it done. I think it's largely due to KitKat limitation. Is your N3 running on KitKat? Can you get the benchmark done?

Yup. My N9005 is running on 4.4.2.
Taken from wikipedia,
Version 4.4
Applications' write access to secondary storage (memory cards on devices with internal primary storage) is made possible but restricted to their designated private directories only, while full access to internal primary storage is still allowed through a separate application-level permission.
I'm able to do benchmark using A1 SD Bench.
If you were to do a custom location, you only can point to the sd card folder which the application has access to.
The lexar sdcard benchmark results on my N9005 is not good.
20MBps read and 12MBps write
I did a benchmark using the card and its usb 3.0 reader on my laptop and it reads 89.69MBps and writes 47.22MBps.
I got the card from newstead. I bought 3 actually. And all 3 of them gave the same android & laptop results.
Finally, I really thinks that Z2 is amazing and I will definitely switch phone if it does support uhs-i sd card speed.

Wow, that's like double of mine. Thanks.
I've got my answer to whether to purchase Z2 or not.

I don't think that is UHS speed. I am using a class 10 and also get roughly the same benchmarks.

Well your microsd is uhs-i because prior to uhs, microsd maximum speed is 25MBps.
Your read speed is physically impossible without uhs bus speeds.
Uhs-i has a 50MBps and 104MBps version. Looks like our phone is topping out at 50 which means it only supports sdr50 or ddr50.

It means 25MBps in read or write?
EDIT: It means 25MB/s transfer, no matter read or write. With Toshiba Exceria 16G I have 38,8 MB/s read and 22,5 MB/s write.

But mine just says class 10 on the card.

Unlike the Note 3, which has USB 3.0, the Z2 only has a USB 2.0 connector, so you're going to be capped transfer speed-wise.

Sony Xperia Z2 + SanDisk Extreme PLUS UHS-I

That's 34.8 for read and 14.4 for write (Internal SD Card). Sometimes this benchmark shows incorrect names/sections. But you won't be fooled if you'll check the size of memory in the description.

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.

me too kasanRio me tooooo *insert quiet yet evil laugh*
agent2702 I think they really will be much faster 20nm tech is like ssd or some ishh isn't it .. 80mb/sec is pretty nice
I honestly wouldn't need anything larger than 16 and I actually like when my gb of my card matches my phone's internal storage for a total "nice round number"
doubt I would ever record a movie bigger than that not with my phone anyways
That's great... I've seen the UHS-I technology in action on DSLRs and it's great. Makes a huge difference if fluid 720p recordings.
That said, UHS-I cards require UHS-I capable readers. Outside of DSLR cameras, very few devices have UHS-I capable readers, and such readers are rare even on PCs.
If you put in a UHS-I into a non-UHS-I capable reader, then it defaults to a lower speed. I had this discussion earlier when pursuing a Sandisk SD Card that had a UHS-I rating as a Readyboost card for my friend's netbook. Support said that since the netbook didn't have a UHS-I reader, the card speed didn't default to Class 10, but to class 6. So far, I believe this varies from card to card.
To sum this up, do we know if the Samsung Note has a UHS-I capable reader? As far as I know, this hasn't been advertised as a feature. Further, I'd surmise that since I haven't heard of people advertising software updates for their readers upgrading to UHS-I, I imagine readers need different hardware to be UHS-I capable.

I believe they are just calling them UHS class but all new tech based on the article . just stating that they are the equiv of digi cam cards speed and performance wise but for phones ..
@shoobie:
I appreciate the article, but, I'm going to attempt to clarify on what's required for UHS-I cards. Oh, sidenote, I didn't take enough time to look at the picture to note that the cards default to class 10, which is good .
Well, what they're saying is that UHS-I hasn't been effectively implemented into the microSDHC form factor yet, only the SDHC, as DSLRs and the like use SDHC cards or CF Cards (Since DSLRs often have enough room for a larger card reader, since you often lose performance and/or increase the price dramatically when you miniaturize components).
For UHS-I to work, according to the SD Part 1 Physical Layer Simplified Specification Version 3.01, it requires that both the host device and the card be UHS compliant. Summarizing off section 3.9.4... essentially in the past, host devices communicated with the SD card via 3.3 Volt signaling. UHS uses a special 1.8V signaling at a higher speed to communicate with UHS compatible cards.
Now, I'm no engineer, and I haven't gone through the document thoroughly enough, but as far as I can tell, it's not a soft update for the card reader, but a hardware update (or basically a new reader is needed) to be UHS compatible. This theory comes from the fact that I haven't seen anyone announcing card reader updates or flashes that allow their readers to now read UHS-I cards.
The real question is: Did Samsung have the foresight to equip our Galaxy Notes with UHS compatible readers?
Otherwise, they're just setting these cards up for the next generation of phones that will definitely be UHS compatible.

Someone here says that Samsung told them the Galaxy Note *does* support the UHS-1 microSD cards with their higher speeds.

Hope you don't mind my skepticism, but... after reading the post... it reads that "Samsung finally gsve me an answer, it is compatible. "... which doesn't really mean much. UHS-1 cards are compatible in older SD card readers, but said readers do not utilize the new higher speeds for the UHS-1 speed class.
Though, who knows, Samsung might... I'll try to contact them soon, though uh, who knows when I'll get a reply, anyone else want to give it a shot?
Remember, you don't want to ask if it's compatible, you want to ask if the reader is SD Card 3.0 compliant, and/or if it's a UHS-1 capable reader, and capable of reading UHS-1 cards are UHS-1 speeds.

My thoughts, exactly.
The guy did talk about buying such a memory card and experiencing faster speeds with it later down in the thread, though.

64GB Micro SD card do they work on photon ?

hi, I'm looking to buy a 64GB MicroSDXC card
do they compatible with photon ?
can anybody who have them give some inputs ?
thank you.
No, the Photon only supports microSDHC, and like you said, the 64gb (also, anything over 32gb) is classified as microSDXC.
32gb + 16gb internal should be more than enough anyways, provided you use it wisely.
If you absolutely NEED that amount of space, some users were able to use the Photon as a USB host and attach an external USB flash stick using a special USB-F-MicroUSB-M

I've seen a couple reports that they work fine on the Photon, but more that they don't. And the Droid4 and Bionic are reported to work.

The current 64GB cards are generally backwards compatible with SDHC in a lot of devices.

I have a Sandisk 64 card - haven't tried it in my Photon, but it works fine in my Xoom and Cowon J3 MP3 player (linux).
So, I don't know for sure. (My Photon battery cover plastic clips won't take too many more removals or I'd try it)
I got my mom a 64gb sandisk mobile utra microsd card and its works perfectly.She uses the microsd for music and so far she hasnt had any problems.
http://www.sandisk.com/products/mob...crosdhc-and-microsdxc-uhs-i-cards-for-android
the 64GB is the exact one I got her.
Cool - good to know, thanks for the post.
I figured it would work fine in the Photon since it seems to work in about everything else with a SDHC 3.0 compatible slot.
And I got my spare battery cover via eBay today, so may try it soon.
- - and to "MooseV2" that said "no", please do your research in the future before making broad statements; TIA!

I have SanDisk Mobile Ultra 64Gb and so far, so good BUT.........I rarely have anything on it. I use ZumoCast to access all my music, photos, documents on my desktop at home? If Im doing a Server upgrade or something, I'll drag a few movies to card, but other than that, empty!
Everything I have read points to the 64GB working perfectly as long as you format it in the phone (FAT32)

Yea it works, I have a 64GB micro sd card. You will have to insert it and go to storage and reformat the sd card while its in the Photon and it will work. I get 60GB out of the 64GB
Sorry guys
You're in the Photon forum.
(And they so far appear to work in about everything - format in phone)

Let me better explain my "No big difference, so I went back" comment. I had a 16Gb SanDisk Class 4, I was happy. I got 32Gb SanDisk Class 6 for $100.00 and I was happy. I got Komputer 32Gb Class 10 for @ the same. When I compared them read/write, depending on what I was reading or writing, the SanDisk was either faster OR not that far behind, so I went back to SanDisk for the realiabilaty. I now have 64Gb SanDisk Class 6 and I'm happy (Kinda of, there is nothing on it? I either use Google or ZumoCast to acces my desktop at home?)
My suggestion, look for stability, look at the reviews where people smarter than I have done extensive testing. Not all chips are alike. Also, look at your needs. If you take a ton of pictures or video, I assume you would need high write speed. If your a gamer, I assume you would need high read speeds? Just me!
Thanks for the further explanation! I'll probably just pick up the class 6. It's getting rave reviews on Amazon.

Hello there,
After took my time to consider about what to buy and choiced the ZU, I am now looking at which MicroSD to put inside and got really attract by the sandisk extreme pro in 32Gb. In term of perf in both random and sequential transfer are top notch and as been proved to be even higher than the actual transfer rate given by Sandisk (tested on computer). I saw several benchmark and it was proven to have about 2 times the transfer rate of a sandisk microsd ultra on a galaxy SIII and Note 2.
Now I wonder about how does it work on the Xperia Z Ultra, anybody have this card and did run a bench?

See the above link. Unless the ultra supports UHS-1 you will get class 10 performance. You will still get quicker than the normal class 10 cards but your not going to get the full achievable performance out of the card.

Anyway I didn't make this post for trolling about cards, just wanna know if someone actually use it on the ultra and have some results. Always so annoying to talking about memory cards because each person have his own way of thinking about it. I am not a newbie memory card user, I know the details and how it work. So no need to come and say things that are not at they place on this thread.

Funny, really. I have already 3 different microsd class 10 from classic 8 gb to ultra 32 gb and I can tell that the transfer rate is really different. We are well in the 10 mb transfer rate guaranty but they can do far more than just this. I got big difference with swap partition on the 32gb ultra than the 32gb classic. Random and sequential access are grandly improved and same goes for the new extreme pro. And benchmarks on PC and Android show it too, or maybe everybody lie and bench are good to be throw on the recycle bin.

Its the devices that are holding these card back.. If you look at the test results on Androd police the cards are achieving much faster speeds in a card reader hooked up to a pc.

Class 10 sandisk 8gb classic 10-12 Mb/s
Class 10 sandisk 32gb classic 10-16 Mb/s
Class 10 sandisk 32gb ultra 16-24 Mb/s
It is different! Root access modify read ahead and some other commands values and the ultra give better results. So if the phone can treat transfer better and modify some value that influence cache treatment and i/o database performances you can, with a better card have better transfer rate.

It is different! Root access modify read ahead and some other commands values and the ultra give better results. So if the phone can treat transfer better and modify some value that influence cache treatment and i/o database performances you can, with a better card have better transfer rate.

yeah of course i was rooted on both devices, but left the I/O read-ahead alone... but after the cache is gone, it still bottlenecks to the speed the card and device can handle. (I'm talking 100mb files for testing here)

Android and new devices handle it very well. Old devices had trouble to handle 32gb but now it can take on 64gb without problem.

Thank you, Im glad to hear that! Yes I remember the days when having an SD card in my android device back in 2010, from time to time I had to stick it in the computer and delete the partition with gparted to start all over.
Got my microSD extreme 32gb and here as attachment a sd card bench with the internal memory as well.
The internal memory speed is really amazing, no wonder why games launch so fast. And it clearly show that Sony gave us a really amazing sdcard reader, 41/31 show performances above of what a microSD ultra can give.
For those interested to bench your memory you can use A1 SD Bench available on play store. For test your sd card you need to set the directory manually. /storage/removable/sdcard1 and for more accurate results select long test.

I used 64gb micro sd card in my old samsung galaxy s2. It worked fine with no problem. It will work in the Z Ultra also.

Lets Talk About SDCARDS

So what micro sdcards are people using as i need a new one want 32GB at least. Does it support 64? Preferably an amazon link!
link below, you can go 64gb or 128gb if you like. on 4.4.2 you might have to do the KK SDcard fix, which is simply editing a file in permissions and allowing RW access to the sd card. Might be the same for Lollipop, but I'm not there yet on my phone.
One thing I did find is that I get lag if I stick loads of music on there and use the stock app, so I use rocket player as it handles that better.

I think I read somewhere that the G3 actually supported up to 3TB SD cards ! (And yes, I know there's no card that big, but it just means it works ! )
Just get any class 10 sd card.
Just as a PSA, Best Buy is having a pretty good sale on Samsung micro sd cards. I got a 64gb "evo" for $25. Steady write rate, according to us file explorer, on 40mbps.
I can finally explore some 4k recording.
Sdcards for LG G3
In most regions the LG G3 comes with a hearty 32GB of internal storage, leaving nearly 25GB for you to use as you wish. As is often the case, one size never fits everyone — and if you need more than 32GB in your mobile device, you'll have to resort to using an external SD card to expand it. The LG G3's MicroSD card slot supports up to 128GB cards, giving you more room than you'd likely ever be able to fill.

Since I'm newly out of iPhone world, and into LG G3, Android and sdcards ... and I already had a problem with bad 32gb (fake chinese) SunDisk sdcard, which could write to it , but every file wouldd in a day or two get corrupted .. When I inserted the old (and slow) 16gb card , it works as it should...
But, could You refer me or explain, what can / can't I put on the card in my LG D858hk, with 4.4.2. Android. What can I do on stock LG Android, and what with rooting ?
Also, recommend some good quality 32gb at least , preferably 64gb ... since I am a massive hoarder of music etc.

You can put whatever you want on your sd card but id just use it for pictures and music etc. As for root its the equivalent of heartbreaking on ios there is plenty out there id do research before doing anything to do with root or bump. And for sdcard just get one with a good r/w speed and your golden i got a 32gb samsung evo card from amazon for aroung £15 they also go upto 64gb

128gb card
I've been using a Sandisk 128GB card for a couple of months now. Currently about half full with music. Reads / writes fine with no discernible real world difference compared to the 16GB card I had previously.
Can't say how it might work with stock, I am Rooted and booted using Cyanogenmod 12 by Manupse. No complaints.

From what I understand, the Samsung Pro cards are great. The one you posted is the last generation one. The current one is rated at up to 90MBps read and up to 50MBps write, and isn't that much more at $59.99.
http://www.amazon.com/Samsung-Class-Adapter-MB-MG64DA-AM/dp/B00IVPU88U
This being said, people tend to prefer the Samsung EVO cards for phone use. They're substantially less expensive ($35.79 shipped):
http://www.amazon.com/Samsung-Class-Adapter-MB-MP64DA-AM/dp/B00IVPU7AO
The reason people tend to prefer the less expensive EVO cards is their faster 4k random read/write speeds, which is arguably the most important aspect for phone use.
Here's the 64GB Samsung EVO micro SD:
Here's the 64GB Samsung Pro micro SD:
If you're using it in a camera, 4k camcorder, or transferring big files, I can see preferring the Pro. Then again, you can get the very similar PNY Turbo 64GB card (up to 90MBps read) for $27.99 shipped right now, which is less than 1/2 the price.

Supported micro SD speeds?

So I've ordered the Samsung micro SD card Pro plus 64GB. It's Samsungs flagship model. This card supports read speeds up to 95MB/s and write speeds up to 90MB/s. But judging by my results I'm not getting near those speeds.

So what speeds are supported by the Z5C?
What cards are you guys using and what speeds are you getting with "A1 SD Bench" app?
By the power of Sony Xperia Z5 Compact
I tried today a Transcend Ultimate 64GB 633x with Up to 95MBs Read and 85MB/s write.
I got 42,91MB/s Read and 28,65MB/s Write... quiet bad in my opinion
I have the same Samsung Pro+ 64gb card and I am not getting anywhere near as advertised either. My read/write speeds are similar to yours.
Do you think this would be due to only 2gb of RAM?

Those speed have nothing to do with RAM. If I were to make an educated guess, the speed depends on the microSD-Card reader and/or the chipset.
I think it's a bit over-simplified to talk about microsdxc speeds without any further qualifications. The manufacturer-advertised speeds are only achievable under ideal conditions (sequential as opposed to random access, specific file size etc.) If the benchmark you're running is different from the one the manufacturer ran, you may measure much lower speeds.
I'm not saying I'm positive the SoC/SD card reader in the Z5C isn't the bottleneck, I'm not sure. My point is that micoSDXC cards are much slower than advertised in real-world scenarios (and realistic benchmarks), even when using them via a super-fast card reader such as a Kingston USB 3.0 FCR-HS4 and a high-endish desktop PC.

I can support dafie's scepsis. My last mircoSD class10 card from Transcend had advertised Speeds of 60mb/s read and 20mb/s write, but actually performed only about 50mb/s read (which is okay to me) and 9-11 mb/s write (which I find very lackluster). I tested this on several card readers (Xperia Z3C, Macbook Air, USB2.0-Adapter on a Windows PC).
@Mythos123 So if you want to know wether the limitation lies within the phone or the sd card I suggest you test it on an integrated sd card reader on a modern laptop or a dedicated usb 3.0 card reader at any decent pc.

Unfortunately my laptop is really old, so I can't compare speeds.
By the power of Sony Xperia Z5 Compact
This is disconcerting because if you look through the amazon-reviews you will also find benchmarks made on android which confirm the speeds that are advertised.
I'm currently using an older 128GB card with only 30MBs/10MBs and was considering an update, but i guess i'm less motivated to do so now.
Did you try with another software?
I've an old "SanDisk ULTRA 64GB" and the results (with that app) are:
Read: 36.17MB/s
Write: 12.15MB/s
I'd like a faster SD capable of write at 70MB/s+ isn't that possible in the Z5 Compact? (If I move games, like Hearthstone from Internal Memory to External Memory they are really slow).
@Mythos123
I just bought one Samsung Pro+ 32GB..
Write speed can't pass 21MB/s with that bench app.
I think we have a very slow card reader or some kind of bug. (Yours write a 36MB/s at least).
EDIT:
- I formated the 32GB SD from FAT32 to exFAT (because Android formatted it as FAT32).
- If I do this test (with this app) many times in a row (using the quick test), write speed raises up to 35-37MB/s, so I think sdcards tests don't work fine at the moment, and...37MB/s is the peak for our card reader.+
- The sequential write speed using USB cable (and USB 3.0 port just in case is above 30MB/s and supported by the Xperia) is 20MB/s approximately. (Copied a .MKV of 15700MB in 13.5 minutes).
So, in summary:
Max sequential write speed achieved with an app: 37MB/s
Max sequential write speed achieved with USB and MTP protocol: 20MB/s.
Such a pitty, Smart phones are in many ways still way way behind desktop and laptop solutions..
I suppose to really compare, you'd have to find a benchmark test on an review. Then use the exact same software and test it on the Sony. Repeating the test as closely as you can.
I've got a 64gb card now (samsung pro) also. I've been thinking about upgrading to a 128GB or 200GB. Has anyone tried getting a larger card? or are those all slower. (I want to carry a copy of all my photos around with me rather than use up precious data whenever I want to look at one)
All Z1 to Z5 limited to 40MB read/write by the card reader chip.
There's really no use for getting fastest cards. They will all be limited by the phone speed

So based on this, what's the most value for money card to get?
EDIT: I mean, I'm reading some information online about needing a UHS-I "U3" class card for 4k video recording. With a 40MB/S read/write limit, isn't it going to be impossible even if we use a "U3" card?

Sandisk Extreme microSD(mid class), no need Extreme Pro(high-end). If you want Samsung, you will still to buy EVO Pro as the entry level of EVO Plus got only 20MB/s write. Samsung and Toshiba seems no medium classes.
I previously own m4 aqua, and i have sandisk extreme
I got 42MB/s read and 36MB/s write on m4 aqua
The card is advertised as 60MB/s read and 40MB/s write speed and displays the UHS Speed Class 3 (U3) designation
I never do benchmark again after switch to z5 compact, but I think the result will be same

Video recording is using Mbit while sdcard is using MByte .... 40MB/s x 8 = 320Mbit
There is no any consumer level of DSLR/phone reached [email protected] yet but a higher speed card is always help because probably it takes a shorter time to writing data and hence, reduced heat and save battery. Take a example, 200MB for a 20MB/s card spend 10s while only 5s needed for a 40MB/s card and you saved battery for that 5 seconds and generated smaller heat as well.

Modern entry level card got a much faster speed usually has 15~20MB/s write and very valuable. In the old day slow card is real slow with just 4~8MB/s writing speed.
