Sandisk Extreme Pro 64GB
[Samsung Galaxy S7 Edge Accessories] southsideswaggar:
Just got a (MB-MD64DA/AM) Samsung Pro+ 64GB U1 and ran Androbench on it. I must say I'm not a SD card geek but it does what I need and have had no Issues with it. It's a waterproof card which so is my Galaxy S7 to a point, it's x-ray proof, magnet proof, and it's temperature resistant with insane operating temp tolerances and 4k UHD video compliant. Included is my benchmark and just wanna say for the price I'd recommend it to anyone.
[Samsung Galaxy S7 Edge Accessories] Travisimo:
So I'm getting the Galaxy S7 Edge tomorrow, and I am mightily confused about Microsd cards. I'm reading all kinds of conflicting reports on what is required for 4K video recording. Many of the recommendations are for a U3 card because those have the greatest write speeds. But correct me if I'm wrong as I try to parse the data:

Galaxy S7 records 4K video at 48Mbps maximum

U1 cards are rated for a minimum write speed of 10MB/sec, which is 80Mbps

Most U1 cards write faster than 10MB, usually in the 15MB+ range, which make them 120Mbps or better

Even with fragmentation and some overhead taken into consideration, it seems to me that any U1 rated card should be more than fast enough for 4K recording on the S7. Obviously there are some prosumer (or better) digital cameras out there (like the Panasonic GH4) that can write at higher bitrates than 48Mbps, so I can see needing a U3 card for those. But for the S7, it seems to me that those who are insisting that a U3 card is needed for 4K are really over-recommending. Now obviously if money is not an object, then of course get the fastest / highest capacity card available.

Please correct me if I'm wrong, but wouldn't any U1 rated card work just fine for 4K recording on the S7 with no worry of dropped frames? I don't plan on putting apps on my memory card, so it will be used exclusively for photos and videos (and yes, I will be shooting in 4K). I'm looking at either the Sandisk Ultra 200GB (which is U1 and should work fine for 4K if I am correct) or maybe the Evo+ 128GB.

It's easy to find many articles that just say get a U3 card or that only U3 cards are good enough for 4K. But I'm having more trouble finding actual real-world results from users who are using U1 cards with or without success in reliably shooting 4K on the S7.
[Samsung Galaxy S7 Edge Accessories] flarbear:
I say pretty much the same thing in the first paragraph of the first post. The 4K video rates on these phones don't seem to be high enough to warrant the typical speed requirements.
[Samsung Galaxy S7 Edge Accessories] GoMoeJoe:
Lexar has never let me down.
[Samsung Galaxy S7 Edge Accessories] Galactus:
What you need to take into consideration is regardless of your sd card use, a slower card can still be a potential bottleneck in the system. You only need to do a search for people who had slow wake up trying to wake up the phone when use cards with slow write speed.

Still, it is up to you. The sandisk ultra cards should do the job
[Samsung Galaxy S7 Edge Accessories] Travisimo:
If I'm only using the sd card for storing photos and videos, why would it cause a slow wake up for the phone? Does the phone have to write to the card when it wakes up?

I found a Sandisk Ultra Plus 128gb at Best Buy for $38 today, so I'm going to give that a try. Has an 80MB/s read and an unlisted write (though it is U1), so I'll be benchmarking it to see how it performs in my S7 Edge. I don't expect to have any problems with it, but I'll be looking for wake lag or dropped frames in 4K video.
[Samsung Galaxy S7 Edge Accessories] Travisimo:
OK, got my S7 Edge set up yesterday, stopped in at Best Buy and bought a "Sandisk Ultra Plus 128GB" microsd card. Downloaded A1 and Androbench, and here are my results (yes I remembered to select the external storage in Androbench). Not sure why there is so much disparity between the two benchmarks? Either way, it looks like the write speed will be just fine for 4K video on the S7. I will report back with my actual experience.
[Samsung Galaxy S7 Edge Accessories] Galactus:
You're fine with that. That card has mixed write speeds. I've seen as low as 20MB/s.........which is not bad but obviously knowing that some versions of the card can do 30/40MB/s can hurt. You're good to go.

[/COLOR]Anyone have any experience with this card on their S7 Edge? Sandisk Ultra Plus 64gb class 10 uhs 1

http://www.bestbuy.com/site/sandisk...-red/3142644.p?id=1219088216907&skuId=3142644

I would mainly use it for storing music for playing, if I do some recording on it would probably be 1080p since I don't really need to record 4K. My main concern is that the card would make my phone slow and laggy like some early reported with their phones.

Or this one?

[Samsung Galaxy S7 Edge Accessories] Travisimo:
Yep, it seems to be working fine. I have not experienced any wake lag, dropped frames, or anything else that would indicate the card is a bottleneck. I'm not sure why there was such disparity between the two benchmarks, but either way, I'm pleased with the card. I bought it for $38 at Best Buy and it's 128GB. I think that was either a flash sale (pun intended) or a pricing error because it seems like it's $60 now (and everywhere else).

[Samsung Galaxy S7 Edge Accessories] Darkstriker:
The first post this as the UHS-I U3 card (but you make no mention of the exact specification). But given the speeds, it looks like it an older version of the Sandisk Extreme with UHS-I U1. Any chance you could check this for us? Sandisk has a very good rep on their cards, so I would be surprised if a card scored below the minimum spec.
[Samsung Galaxy S7 Edge Accessories] LocotesKilla:
Hey peeps.

I work in a mobile phone repair shop and recently got some new stock in, among them were some sd cards. I decided to benchmark them as I fancied an upgrade from my Sandisk (class 4) 32gb. The Sandisk Extreme 16GB (UHS-I, U3) was the best available so I kept it, for free! :)

First up, the Sandisk Extreme 16GB (UHS-I, U3) I decided to keep for myself.

Second, another Sandisk Extreme 16GB (UHS-I, U3) for comparison.

Third, a Sandisk Ultra 16GB (Class 10).

If I happen to come across any better sd cards, I will be swapping out for one and benchmark again. Enjoy :)
[Samsung Galaxy S7 Edge Accessories] stijnx6:
i have a new sd card in my S7 edge, its an sandisk extreme SDXC UHS-I.

I am not into all that technical with the cards. If I just want a fast speed durable 64gb card which one should I get?
[Samsung Galaxy S7 Edge Accessories] tiho5:
I bought the latest Lexar 128 gb, but it's just not good. Phone freezes and the card is not discoverable.

I have to format the card again and copy again everything on it from my backups to make it work again. And in a couple of weeks the same thing happens again.

Could anybody recommend a fast (the fastest) and reliable 128 gb SDXC card?

SD Card issues

Hello All,

I brought a S7 Edge recently and i brought a 64GB Samsung Evo Sd card and after i put the card my phone had some issues and like phone slow, hanging up, couple of restarts and also noticed whenever i restart the phone it used to SD card corrupt under storage and so formatting the card is the only option for it to work and so had reset the phone too and same issue and so got a different 64GB Samsung Evo Sd card even that had same issues but the same card worked great on different S5 phone and had same issue on different S7 Egde phone and so got my phone replaced and now even the new phone has the same issues. I am going Crazy

Phone Replaced and Memory Card replaced
[Samsung Galaxy S7 Edge Accessories] Semantics:
I'll stick with the 200GB that came with my LG V10. I have never had an issue with music or anything, don't see the point to get something that says "ultra" on it, when the free class 10 that came with the phone hasn't let me down yet.
[Samsung Galaxy S7 Edge Accessories] flarbear:
That type of card may suffice for a lot of uses, but it will have its limits...

Most cards read fast enough that they will suffice for just about any use if you are reading from them (such as playing music or playing a 4k video file).

Nearly any card is much slower on writing though, and that is why the class system of speed ratings was created - to make sure it can keep up with any real-time writing needs you have. If you never record a high bandwidth stream to it in real time then you will never run into this limitation.

Music is also pretty low bandwidth compared to video, especially 4k video. It's unlikely any use of music or audio files (whether reading or writing) would ever stress a Class 10 card.

But, 4k video, and in particular writing a 4k video stream in real time while recording it, is the one application that will exceed the guarantees of a Class 10 card. You need a U3 card (essentially a Class 30 equivalent) to be guaranteed to keep up with real-time 4k video recording.
[Samsung Galaxy S7 Edge Accessories] Semantics:
I've taken some 4k video with my V10 in manual mode and I didn't notice any issues with it. I really don't record in 4k, though so my sample size is fairly small. Seems to make sense though, if someone records a lot of 4k.
[Samsung Galaxy S7 Edge Accessories] flarbear:
Interesting. After I wrote that I went looking for typical bandwidths for 4k video files and didn't find much except a few sites which listed figures that would suggest that even 10MB/s was enough.

So, I took a short 4k@30fps video with my S6 edge and for 12 seconds of video it was only 66MB which works out to only around a little over 5MB/s which is definitely under the limit for a Class 10 card.

The SD card association's literature on UHS speed ratings usually mentions higher bit rates, but they could be referring to high quality encodings of 4k movies which might have higher bitrates than the MP4 encoder built into our phones.

If anyone can find an actual spec for the bitrates for these phones, it would help to know.

Until then, faster write times will still help with loading the card with music and photos and faster read times will help with things like the media scanner reading thousands of pictures to generate thumbnails. Faster can't hurt in those situations, but it's not going to break anything.

The Android Marshmallow feature page for the SD card adoptable storage feature mentions that you should have a UHS-I card with a U1 rating to use the feature. A non-UHS-I card that is Class 10 would have the same minimum write speed guarantee as a UHS-I/U1 card, but it would lack the high speed bus that a UHS-I card has. They mention that a Class 4 card can be 10x slower than internal storage, but in that case a UHS-I/U1 card is only about 2.5 times faster than a Class 4 card so it wouldn't keep up with internal storage. A UHS-I/U3 card would be close to 10 times faster than a Class 4 card so it would be a better match for using the adoptable storage feature.
[Samsung Galaxy S7 Edge Accessories] Captainblade:

For what it's worth gopro recommends uhs 3 cards for 2.7/4k video. Probably a good idea on where to start.
[Samsung Galaxy S7 Edge Accessories] gvayl:
So what's the bottom line...while we wait for the new cards to come out...what is recommended?
[Samsung Galaxy S7 Edge Accessories] Semantics:
If you plan to use the phone for a ton of 4K video, I'd say get one of the pro cards. If you want it for music, pictures, 1080 video, get the biggest class 10 you can afford.
[Samsung Galaxy S7 Edge Accessories] vivelafrance:
Bottom line is that it is definitely not necessary to buy the fastest card for this phone! Simple as that. Fastest cards are for GoPros and high end cameras
[Samsung Galaxy S7 Edge Accessories] steve4335:
I would stay away from Sandisk, they are all advertising and marketing... consistanlty testing lower than the competition. I have also had problems with them in the past, not to mention there is known issues with Sandisk in Samsung devices. Samung pro+ cards are amazing, I also have had great experience with Lexar

I am currently using this one:

http://www.amazon.com/Lexar-High-Pe...id=1456614814&sr=8-2&keywords=128+micro+lexar

this one here is one of the fastest on the market...however you will pay for it:

http://www.amazon.com/Lexar-Profess...id=1456614814&sr=8-1&keywords=128+micro+lexar

if you don't need that much space, this one is fast enough for anything currently out there

http://www.amazon.com/Samsung-Plus-...=1456614935&sr=8-8&keywords=pro+micro+samsung
[Samsung Galaxy S7 Edge Accessories] gvayl:
So now how do we find out what the phone's max read/write speeds are...irrespective of the card. I wonder what if the phone can't handle some of the fast cards? Is that possible? Can we get the specs on it's reader?
[Samsung Galaxy S7 Edge Accessories] vivelafrance:
well, when you get your phone, you take a video. You check the size and the length of the video and there you go, you have the minimum MB/Sec you need on the card to be able to write information Live.

If 1min of video is 600MB, then you need a card that can write at least 10MB/Sec.

[Samsung Galaxy S7 Edge Accessories] flarbear:
Does the bitrate vary depending on content? I did that experiment with my S6 Edge, but since the room was quiet and since the subject matter was "what was on the desk of my home office", I'm not sure I stressed the codec to its maximum bitrate potential. What kind of material would produce the worst case 4k bitrate?

(For the record I got 66MB for 12 seconds of video which is pretty low bitrate...)
[Samsung Galaxy S7 Edge Accessories] flarbear:
I updated the OP with a breakdown of information about the card formats, bus speeds, and speed ratings, hopefully it will clear up some confusion for posters new to the thread.

One thing I've come to understand, though, is that the new cards coming out that claim 250+MB/s read speed will be using a half-duplex mode. They can only achieve that speed over UHS-II by shutting off writes while they read out at that speed. It remains to be seen how devices will handle that - if it will be a mode that you have to enable and then your I/O turnarounds will be slower because they have to wait for pending reads to finish before they can write, but your sequential burst speed will be faster - or whether they will dynamically choose half or full duplex on the fly and how good they will be at making that choice in an environment where your reading and writing behaviors are dynamic and potentially unpredictable...
[Samsung Galaxy S7 Edge Accessories] enjoythemusic:
Thanks for updating OP and my friend at Samsung said single row contacts UHS-1 is what is within the S7 series. They're checking on other specs tomorrow and will update here according. I'm still going with a UHS-II 1800x Lexar as I have plans and hate waiting on data transfers. For me, 40MBs feels like slow death as I use pro video and pro still imaging (camera) gear.
[Samsung Galaxy S7 Edge Accessories] nazzo123:
I had just bought a 64gb samsung pro plus card from ebay for $29.99 from a trusted seller with lots of ratings.
[Samsung Galaxy S7 Edge Accessories] Borfas:
LEXAR: http://www.lexar.com/products/professional-microsd-1000x

is a better all micro sd card!
[Samsung Galaxy S7 Edge Accessories] flarbear:
That card has an impressive advertised read speed, but they make no claims about write speed.

Since the S7 lacks the extra pins for UHS-II transfer speeds, it will be limited by UHS-I maximum transfer rates anyway which means it cannot be any faster than any of the fastest UHS-I cards that currently produce 90-100MB/s reads and writes. Given the comments on Amazon, the Lexar seems to benchmark at around 45-60MB/s write performance and so will not be able to match the 90MB/s write rates of other UHS-I cards.

So, until you have a device that supports UHS-II (which is a hardware issue, not a software or firmware issue and the S7 does not support the hardware for UHS-II), that Lexar card will be more expensive, but likely worse in real-world performance in your S7 than, say, the Samsung Pro+ card which advertises and tests out to have pretty much the best speeds that UHS-I will allow (though its random read results may not be quite as high as the Sandisk Extreme Plus).
[Samsung Galaxy S7 Edge Accessories] NoelBonel:
Go for sandisk. I have the 200gb microsdxc card now. So far so good.
[Samsung Galaxy S7 Edge Accessories] Tjalling:
Hey guys, I just quickly sorted the charts from the OP by seq. write speeds (my justification for that choice is that the read speeds of any of the top cards fall into the category of 'good enough'). I hope this serves as a quick summary for anyone looking for a card that's the best given their own price range, like me.

Has anyone tested a really fast card in here? I want to know the max read/write speeds of the device itself. Trying to find out what read/write speeds the device is able to achieve. I purchased a Surface Pro 4 and its microSD card slot cant handle the UHS-II or U3 speeds at all, so it would have been a waste of money. Attempting to find out if this is the same thing here, which I have a feeling it is. From what I have been seeing in this post it looks like 90/90 would be the max for the card itself.

Thanks

I believe I read somewhere that Qualcomm has specified the SD slot as only handling UHS-I speeds...

But I guess that only applies to the US models with the Snapdragon. Not sure about the international one.
[Samsung Galaxy S7 Edge Accessories] Gizumhi:
SanDisk 128 extreme seems a good option, the main problem of sandisk is that some users reports for corrupts sd from this brand. Things that seems not to happen on Samsung ones

Just make sure you backup your SD or put things on there you may not care if they get deleted, such as apps.

Any kind of storage medium is prone to corruption.

I would suggest at least 2 extensive formats using your computer before partitioning a new SD.

Is that the UHS-1 Class 10 card? Do you have a model number or a pointer to the same card on Amazon or the SanDisk web site? The reason I ask is that they have a couple of different cards with the same name, but different speed ratings and colors so I want to represent the data accurately in the first post and charts.
[Samsung Galaxy S7 Edge Accessories] flarbear:
Just a quick note from the OP that I'm not actively monitoring this thread any more so it may take a few weeks (months?) for new benchmarks posted at this point to appear in the list in the OP and in the charts. Many of us chose a card from among the many worthwhile cards listed already and are happy with our purchases and there doesn't seem to be a lot of room for any cards to perform radically better than what has already been reported, so I'm not expecting any earth shattering new info to surface.

And, as always, I hope someone might prove that assessment wrong, but time will tell and I'll be checking in from time to time as I have spare time.

Good luck with your phones and cards all!
