First questions... what makes a great microSD card?
If you need the card for a smartphone, its 4 kilobyte random read and write speeds are very important.
In most computer file systems, applications will write little bits of data in small chunks, scattering it all around the storage device. So 4K speeds are a good measure of this type of usage.
Sequential writing speed, on the other hand, is important for shooting photos or video–you need sustained throughput for large amounts of data, not bursts of speed for teensy bits of it. So while 4k read and write is predominantly important, sequential can also play a minor role especially for image recording/ capturing.
Why is this important... well, the 4K random write speeds on some Class 10 microSD cards are absolute junk. Their sequential write speeds may be great, but their random write speeds are terrible. So for average use in a smartphone its really important..
Here are some facts I've tested and discorvered using my Ultra, my 4 SD cards I have.
** Note this was for my own use, and official test results from manufacturers will vary, and probably crap too!! **
Sequential Read/Write
Brand - GB - Class - Read - Write
SandiskULTRA - 64GB - 10 - 20.07 - 13.48
TranscendULTRA 32GB - 10 - 22.36 - 11.96
Lexar - 32GB - 10 - 20.13 - 11.38
Samsung - 32GB - 10 - 18.65 - 11.53
Random 4k Rear/Write
TranscendULTRA 32GB - 10 - 4.073 - 1.989
SandiskULTRA - 64GB - 10 - 3.933 - 1.921
Lexar - 32GB - 10 - 5.468 - 0.008
Samsung - 32GB - 10 - 3.328 - 0.798
Results:
So while the Sandisk Ultra 64Gb has a higher sequential read and write speed, the Transcend Ultra 32Gb has a very slight edge in read speed in 4k tests. Other brands like the lexar and samsung were utter rubbish when looking at the 4k write speed.
So if looking for a new card, and you want a 64Gb, then the "SanDisk Ultra 64Gb" (Class 10 or UH-1) is the best buy.
I couldn't test the Transcend 64Gb as I don't have one, however I would expect it to be similar the the SanDisk (perhaps even better)
Hope that helps guys..
I got a Sandisk Extreme 32 Gb and it go up to 40 Mb read and 30 Mb write in sequential. Tested directly on the XZU.
Some test show really impressive results on computer.
If you know a way to test random directly on the phone I could give you the results.

What tool were you using? The cache read a head will be working against you in a test using straight data. You'll need to use a tool, that will not use the first few seconds of data read/write

A1 SD bench calculate the caching at first run and then ignore it for the second time. For an accurate test best is to go on the settings and select the long bench test.
The XZU have an incredible hardware, even for the microSD slot it give X2 performances (with a good MicroSD) compare to the competitors.

Yeah this is what I scored:

Picked up a 32GB class 10 plus card from samsung today. MB-MPBGCA/EU
Didn't have the guts to buy a 64gig if it will brake.
I don't care for speed because I store only my music there and my old class 4 card already does a good job playing back my .flac files but I needed the space.
But just for curiosity

would you give me a short evaluation of it?
I currently have a 16GB SanDisk Class 4 SD card that I bought at RadioShack for $29.99. I'm looking to see what people think as far as certain companies stack up and what the read/write speeds are as far as advertised/reported, and just a general summary of your card.
If you're interested in contributing, tell me what company made your SD card, how many gigs it holds, rate it on a scale of 1-5*, and then anything about your card that you feel others should know, i.e. it's rated at class 4 but you're getting class 10 speeds.
So, for myself, it would look like this:
- SanDisk Class 4
- 16GB
- 5*
- Card is reliable, I have had no problems with it, and using SDTools from the Market, it was showing 5.3Mb/s write and 10.6Mb/s read. I would recommend this to someone looking for a good card at a good price.
I'd love to have a lot of responses! Even if you're just using the stock 8GB card, I really want this to become a helpful guide maybe(?) for people to use when looking at getting a new card, because there is a lot of info out there and people are reporting different things for the same card.
So let me know what you're experiencing.

Well guys I have a 16Gb Sandisk I think is a Class 2 it cost me around $20 like 4 months ago... and I would rate as 5 I never had any issues with it.. I get 6.6MB write speed and 19.1MB Reading.. I want a 32GB one but I don't know much about hope someone can recommend me a good one...
and Great thread...
Kingston class 10
32GB
4* (8.3 MB/s write, 19.2 MB/s read)
8.3 MB/s is acceptable for dayly usage, but i expected more of a class 10 card for the price I payed, thus 4*
Transcend class 6
16GB
5* (15.8 MB/s write, 17.4 MB/s read)
absolutely happy with the speed on this one
(not rating the few 2, 4 and 8GB class 4 cards of various manufacturers i got laying around)
PNY 16gb class 10. BUT I DO NOT RECOMEND, I have had the data on the card go corrupt on it 4 or 5 times in the 5 months I have had it. It was cheaper then the PNY 16gb class4 at best buy and now I know why. I'm actually about to head to the store right this second to get a new card.
SanDisk 32GB. Was listed as a Class 2 I believe but doesn't have a Class number on it. I have no complaints at all. Used it on my Evo 4G and now my 3D. Bought it direct from SanDisk when they ran a less than 24 hour sale( maybe a mistake) for less than $60 shipped. I get 6mbps Write and 13mbps Read. SanDisk always outperform there Class ratings though, can't go wrong with one of their storage cards!
EDIT: When swapping batteries today I pulled my sd card to have a look at it. It DOES say Class 2 on it. Very nice speeds for Class 2, but that's SanDisk for ya!

You mean SDXC cards? They're super new aren't they (read about Sandisk announcing a line of them just last week). No guarantee they're compatible with the EVO 3D, though the SDXC spec seems to read that it'll just be a firmware update to make SDHC drives compatible.
I know one guy mentioned he had ordered on over in the thread discussing the Sandisk announcement. No word from him yet.
sdxc
Yeah i have a microSD to SD converter so i can get cheaper and more capacity cards.. but then i realized the spec of the phone is 32gb. but is that only because microsd only goes to 32gb? I need to find someone with a 64gb card so i can test lol
Using a PNY class 10
16 gig
5* i typically see about 12mb write and about 18mb read when i transfer ROMs to/from my comp. it performs like that consistently.
i have always had good experiences with PNY. i use them religiously in all of my cameras. they are right up there with sandisk, and a tad bit less expensive. this is the first time i have used one in a phone, and i'll say it again (as i did in another thread), sandisk underrates their products, and PNY rates them exactly what they should be.
hope this was useful!

Really??
Is it this one:

I have the same card and it can only muster this:
I am looking for recommendation for a 32Gb Micro SD card that is the fastest and most stable for use in the AT&T Note.
Currently I have the following but they're not good:
- Kingston 8GB Class 6: REALLY slow - tansfer rate below 1 Mbps
- Transcend 32GB Class 4: slow - transfer rate about 2-3 Mbps
Both were bought from Amazon and as you can see, even a Class 6 MicroSD can have lower performance than Class 4, depending on the manufacturer.
You can check your MicroSD card speed using this tool from Google Play. The screenshot from that app shows some insane card speed, as shown below:

Thanks all for the recommendation and the screenshot!
Looks like Samsung and Polaroid CLASS 10 is the way to go. I will research the price and buy on of these.
By the way, a friend of mine recommended the NEW Sandisk SDXC. They seems to be more expensive, but if the performance is similar to regular MicroSD, what will be the advantage?
I think most any class 10 will provide similar results. There are some that guarantee certain speeds, and they may be better performers, but you'll often pay a bit more. The class refers to the speed, most manufacturers will report their best case scenarios to qualify for a higher class rating. http://en.wikipedia.org/wiki/Secure_Digital#Speed_Class_Rating So you'll find some class 10's do out perform others and such.
SDXC just refers to the capacity the cards can support. I believe SDXC supports up to 2tb vs SDHC is up to 32gb. (there are other technical factors too)
Just be sure that it is indeed a MicroSD card, and not just a normal SD card.

Not sure if anyone is still looking at this thread, but I just did this test on my phone with my 32gig Samsung Essential MicroSD card. I've owned it for a couple months now and as far as I can tell it's been rock solid.
Read speed was 9.7mbps
Wtite speed was 22.4mbps
Best part, it was only like $30 on NewEgg. Great deal for a class 10 card.
Not to further complicate things. There is another notable rating
Class 10 UHS-1
http://www.amazon.com/SanDisk-micro...DSDQUA-032G-U46A/dp/B007XZM6VG/ref=pd_cp_pc_1
Class 10 SDHC
http://www.amazon.com/SanDisk-Mobil...51467765&sr=1-3&keywords=class+10+micro+sd+64
Pay close attention to the little symbol that indicates its rating. Don't be fooled by a lower value. The shape around it indicates a type.
So whats the deal? I have an answer for you. This ever confusing class and rating jargon can best be cleared up from the horses mouth.
Behold the SD Association and its wonderfully CLEAR explanation.
Yup its real. They are responsible for a great many things in the memory world. They even have provided all of us with the best SD format tool we can get our hands on for free. Because they know there SD stuff that's why!
So back to the ratings. I personally have not ever tested a UHS class SD in our device or any other phone for that matter. Based on this quote "UHS (Ultra High Speed), the fastest performance category available today, defines bus-interface speeds up to 312 Megabytes per second for greater device performance. It is available on SDXC and SDHC memory cards and devices." I would love to know if anyone has successfully used one.
Weeeeellllll I ordered a 64gig UHS-1 from Sandisk.
Seems the research I did supports Android and mobile OS use very well. So ill give it a go and post some results when it arrives.

Careful with the SanDisk UH devices... My 32gb SanDisk UH-1, bought from amazon and in retail packaging, was a pain in my Note from day one. The problem got worse over time... at first i thought it was just JB roms, not hardware. It constantly caused reboots, would unmount itself, and was slow, no matter which ROM was installed. After 3 months, it died last week... it mounts/dismounts every second it seem, even in my Mac or PC. Put in for an RMA with SanDisk... we'll see how that goes.

I'm consistently getting 8 MB/s Write and 35 MB/s Read in SD Tools. That read speed seems crazy-high for such an old card. I'm using a Class 6 A-Data card that I originally bought for my HTC Magic over 3 years ago. Not sure if it's random or sequential, though. I imagine that random is much more important wrt apparent speed browsing through things like photo albums and music folders.

Hi there, I was wanting to make a list of SD cards that work with our L9's so others can buy a card that works fine without worries. I have read online that eBay sellers sometimes sell a 2-8GB card that is reformatted as a 32GB card and once a file exceeds the 2/8GB original capacity, the card goes haywire and stops working. Beware of eBay for MicroSD's. Also, this is good to know.
I was also thinking of listing benchmark scores to show which of each size of SD card was best for our phone.

8GB's
Samsung 8GB MicroSDHC Plus Class 10 - Works great!

32GB's
Adata 32GB MicroSD Class 10 - Works Great, cheap too!
Samsung 32GB MicroSDHC Plus Class 10 - Works great!

If people could post what SD card they use and if they have had any issues with it while using the L9, I can build up the list.

Is that a hardware issue or a software issue for the slow transfer rates? I have used Rom Toolbox Pro to increase transfer speeds and Pimp My Rom to apply I/O tweaks to internal/external storages. Not really sure if it made much difference

Adata are great cards but Sandisk is not that much more expensive if you're searching online. On Amazon it's only a 3 dollar difference. Around a $6 difference on Newegg. So you have options.

16GB SanDisk Ultra microSDHC UHS-I - working fine, but can`t reach maximum transfer on my P760. Card is working wonderfull on PC but I think L9 isnt capable to handle such a r/w speed... Anyway - I recommend this card.

Whoa didn't know this was the post... I scrolled down lots and realized that's a crazy sized sig.
Sandisk invented it, so everything is set by their standards.

It's because of the lower voltage used for the memory card slot on phones . Due to power use and heat they don't have the cards running at optimal speed. They only run fastest at 3.6v but phones drop it down to 3.4 or lower.

Can you use this card in full capacity without problems, phone see it?

Should work when formatted to Fat32, which Windows or the phone won't do, a formatting tool(dont know any) or a linux boot cd will.

Yes, it's real and retail packaging. I can use it's full capacity, settings>storage shows it at 59.46GB. Only fakes fail to use it's supposed capacity.

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 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.

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)

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.
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.
A1 SD Bench:

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.
