Hey guys I didn't see a thread for MicroSD discussion so thought I would start one. It would be good to have thoughts and opinions on the best price/performance cards for the S7, with a view to maximum storage balanced by good read/write speeds for UHD recording etc.
----------------------------------------------
128GB:
For 128GB cards, there are some fast options available:
Lexar High-Performance MicroSDXC 633x with 95MB)s read and ~20mb/s write http://www.amazon.com/Lexar-High-Pe...eader-Memory/dp/B012PQKFNI/ref=dp_ob_title_ce
Samsung 128GB Evo Plus with 80MB/s read and ~20mb/s write speed http://www.amazon.com/Samsung-128GB...7679606&sr=1-1&keywords=samsung+microsd+128gb
200GB:
From what I have seen, 200GB cards are primarily from SanDisk and slower at 15MB/S actual write speed (see some user reviews in the Amazon link):
SanDisk Ultra 200GB Micro SD http://www.amazon.com/SanDisk-Ultra-200GB-Micro-SDSDQUAN-200G-G4A/dp/B00V62XBQQ
----------------------------------------------
The question is, will the 200GB provide enough performance for seamless media and app usage, and UHD video recording, or is it worth going with the 25%+ faster 128GB cards to give an extra boost in write speed?
Bestbuy, b&h, samsung US all had the samsung pro+ 128gb for $89. Had to go with the best tested card for my 4k content. Almost got the evo 128 but you know you get what you pay for sometimes. Way i see it, dont put slow **** in a fast phone.
I have a 64gb evo+ and havent noticed any slowness, but I also havent recorded any 4k video. I do have a 65gb Pro+ on order from samsung (backordered from when they were selling for 30 bucks the other day) to upgrade it though.
I thought about snagging one of the larger 128's but honestly I dont think I will fill up the 64 before my next phone & the next "fastest" card is out so I stuck to the 64gb for now.

I actually found that today (Samsung Pro+ 128GB) after doing some Googling and then promptly ordered it... it really looks like the best option and the price is decent.

Good choice. Was a sweet deal.
Does the Sandisk Ultra 128GB MicroSDXC handle 4K video ok? I'm looking to buy one at a really good price at the moment, but wanted to double check if anyone has had any issues with using this card for recording 4K. Cheers!

I posted on the edge thread, but I have the 128 evo+ and it works fine even on 4K videos. Everyone is so amped up on speed. the bit-rate is fixed and you only need 10MB/s write if that. Mine is at 19MB/s.. The other big reason is for burst shots, but that is forced onto he internal memory so you dont need to worry about that.
So all thats left is the time it takes to tx files between your pc and phone. Does it take 3 minutes or 6.. haha

The read speed between the EVO+ and the PRO+ arent that different. Its the write speed that has the PRO+ being that much better.
And the EVO+ write speed is just a hair behind what is supposed to be there for 4k video so it doesn't surprise me at all that it works.
http://www.gsmarena.com/samsung_galaxy_s7-review-1408p8.php
"4K videos are recorded with a bitrate of 48Mbps, 1080p/60fps are 28Mbps, while regular speed 1080p/30fps get 17Mbps."
48Mb/s= about 6MB/s
evo+ will write at 18-21 MB/s.. more then enough. I would think anymore then 10MB/s would be fine.

Don't buy Samsung SD Cards as reported in this thread(http://forum.xda-developers.com/galaxy-s7/help/galaxy-s7-slow-to-wake-t3326304). Most Galaxy S7 owners around the world have either got a Evo+ 64GB or 128GB.

Hmm. I wonder why both Evo+ and Pro+ get only about 60mb read speed with A1 in S7 and write speed seems to be caped also to 45 ...
Basicly no point to buy Pro or Pro+ at all.
I went with the SanDisk Ultra's with mine and my wife's phone, that was before I stumbled upon this thread. haven't recorded video yet will have to try and report back.

mb write, 16mb read. Benchmarked with AnTuTu in my EVO LTE.
Yes, this MicroSD Class 10 card actually lives up to it's speed. Look at the 50+ reviews it has. 4/5 star rating.
Oh btw, newegg gives free 2 day shipping with any purchase. Yay.
I actually bookmarked this yesterday to grab a bit later.
Here is the link.

@ skull - I was going to get that instead of G.skill one since I've had a good experience with A-data SD cards
I have an A-data 16gb class6 SD card that I bought 4 years ago, still works like a charm!

You know I would be mad at this G. Skill 32GB Micro SD but I got it on sale. Original price of $29.99 and had a promo code on May 13 to get an extra $8 off. Add free two day shipping to that and it's just a sweet deal.
I'm disappointed in speeds but for around $22 it was a steal.
P.S. I know more read/write with an SD card is good, but what for actually? I mean this in all honesty. I have no clue. I can access my songs and apps in less than a second upon touch. Boot time is maybe faster? Someone enlighten me.

It allows you to get stuff done quicker. Burst mode picture will probably be higher quality. The big one for me (and the main reason why I bought a class 10 for the first time) is that it will allow you write to the card faster and ultimately allow you to take a higher resolution video. Might help a little with pictures too in burst mode.
Sorry for going a bit off topic but this is a little of my recent background:
I am a firefighter and I just bought a helmet camera. Since it has 0 internal storage, I am forced to buy an sd card. I was talking to the technology committee (which I am a part of) and they agreed that I should get a class 10 card so I can take high resolution videos of us training and doing actual firefighting. Best part is, I got the station to pay for 2 . After training or whatever, I can take the card out and plug it into my Transformer Prime and I can stream it over the TV.
For the average Joe, a class 10 might not be all that exciting. I haven't gotten one before because I have never felt the need to get one.
I also just got the Gskill card, just no phone to stick it in (grrrrrrr)
Using h2testw on my computer, I got 9.5-10.6 MB/s sequential write speed, and 17ish MB/s read speeds.
Good enough for me.

i believe the card he is referring to is class 10 uhs-1. thats a pretty great deal seeing as i got the class 6 uhs-1 for 40.. i didn't look hard though..
wondering though, card states up to 30MB/s.. is that read time only? will this still well outperform a class 6 uhs-1 for capturing video or does anyone know if both cards are adequate/overkill?
My order is already in packaging. Oh well. I probably would have went with the ADATA anyways since the reviews are generally good.
I bought this card a few weeks ago and couldn't be happier! If you want a true test of the card speed you can not use the phone, use your pc. I recommend using ATTO disk benchmark. I consistently get 11.9 write and 20.1 read. class 10 and then some!

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.
Got mine @ buy.com website -
32GB , Class 6 for $19.90 + free ship ( came via post)
( dont remember which supplier )
Just used the above testing ( was curious)
Got speeds = write = 10.3 reading = 14.4
So gota be worth it > not sure 64Gb (1$ per GB)is worth the money @ moment

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.

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 use a Silicon Power 32GB Class 10 (SP032GBSTH010V10-SP)
It got 13.3 write /20 read
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.
EDIT: haha, OK so apparently you have to go into the root of your external SD card to get actual results. 8/18 on the AData

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.

"Please be informed that UHS-1 (Ultra high speed) is equivalent to class 10. All UHS-1 memory cards have 10MB/s of minimum data transfer speed same as a class 10 card. There is no difference in the data transfer speeds of these memory cards and also they are identical in their technical specifications as well.

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.

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 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.

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.

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.

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)

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.
