Well the Extreme Pro uses a UHS-II bus and has better flash in it. The Extreme Plus uses the same UHS-I bus, and also has faster flash in it.

They're all rated U3 because that is the highest speed class you can claim and it only promises a minimum write speed of 30MB/s which is needed for all applications (particularly 4k video). So anything faster than that will just be rated U3 and the extra speed is not something they can claim with an industry standard. Most cards do list "up to" speeds, though, to give you an idea of how fast the flash is outside of those industry standard ratings which only address minimum performance guarantees. The Extreme only claims it can do a max of 40MB/s, so it is just barely faster than U3, but the Plus claims it can get up to 90MB/s and the Pro claims up to 100MB/s. The different speeds beyond U3 are probably a result of using better flash internally and/or other hardware that streamlines the use of the flash (more parallel operations for instance and more sophisticated algorithms to spread the load across more flash cells for faster throughput).

You may also find that their random read/write rates are quite a bit different as well, but those are rarely advertised on the package. See the first post for a link to a Google doc that graphs the various random read/write speeds we've seen in Androbench on the phone...

I did refer, This one was missing. From what you have mentioned I believe this is good for my S7 4K video. I am going to be using it mostly in mobile anyways and do not do lot of data transfer.

Is the "Android" there part of its official model name? There is a SanDisk Ultra line, but I can't find any references to a SanDisk card with Android in its name. I'll record the results as a SanDisk Ultra for now.

How good is the Kingston Digital 64GB microSDXC Card that I got free with my VR when I got the S7 EDGE. This review shows it to be OK:

http://www.androidcentral.com/best-galaxy-s7-microsd-cards

This Class 10, UHS-I microSDXC card from Kingston features a 64GB capacity and advertises a read speed of 90MB per second and write speed of 45MB per second.
[Samsung Galaxy S7 Edge Accessories] ilordvader:
Read the 1st post -

So, an SDHC, UHS-I, U3 card uses FAT file system with a maximum size of 32GB and an ultra high speed bus (between 50MB/s and 104MB/s) and a guaranteed sustained write speed that exceeds 30MB/s at all times and under all conditions.

As another example, the newly announced cards that claim 250+MB/s read speeds must be using the UHS-II half-duplex mode which means they can only read that fast when they use all data lines for output which requires them to turn off writing at the same time. The sophistication of when to turn from reading to writing (or from full duplex to half duplex) remains to be seen...

What ever you can afford its all on you

How well has it performed for you if you have it in your S7?

I want to upgrade from my 64gb samsung evo (not the evo+) but i'm not sure about this cards performance and what not. Never had a PNY product.

using Samsung Pro Plus 64GB MicroSDXC. when i plug the phone into PC and do anything besides copying something TO the sd card. the sd card window on the PC freezes. even just renaming a folder and the window freezes. but renaming folder through the phone itself is fine. what's the issue?
[Samsung Galaxy S7 Edge Accessories] william58:
There goes China coping/counterfeit something again... I'd never buy a no-name card ever. I've been using SanDisk cards for years in photography and learned over the years you get what you pay for and to stick with the known brands. For me that is SanDisk Extreme Pro Compact Flash. Reliable and fast. I can't take chances with my photography business. Hence I use SanDisk microSD cards in my phones.
[Samsung Galaxy S7 Edge Accessories] dazzer1975:

Hi, I bought a quite expensive (104€)

Lexar Professional 1800x microSDXC 64GB UHS-II from amazon because one reviewer claimed to have speeds of 260/170 together with his s7 edge. This obviously can only be a 'slight' exaggregation, as I know now...

I have attached both results from androbench and A1:

The manufacturer of the NAND (and/or Controller) is Phison Electronics, by the way...

I ponder on sending the card back and getting a cheaper UHS-I / u3 one with 128GB...

Absolutely right! Their service is extra good to as I had a card that I had for 5 years go bad and all I had asked for since it was out of warranty, if they could fix it.... I got a new one in the mail instead, three days later and it was the latest and greatest as mine was a old one. Now THAT is service! That was the only card that ever went bad too and I've had many of them.

all this reading is giving me a headache now. so can anyone suggest a 128gb card or higher that i can use for 4k recording but not expensive
[Samsung Galaxy S7 Edge Accessories] felixthecat:
Hear hear
[Samsung Galaxy S7 Edge Accessories] flarbear:
The Sandisk Extreme Pro and Samsung Pro+ are both competitive with this if you can find a better price. The only difference is that the 1800x will be much faster on reading when attached to a PC with a proper UHS-II reader. It will likely be faster at writing on a PC as well, but the difference will be more modest.
[Samsung Galaxy S7 Edge Accessories] flarbear:
That sets a new bar for A1 SD results for the Pro+, much higher than the other results in the graph. I decided against reordering the graph because there were 2 other results that led to its current sorting position, but the long write bar stands out and draws the eye to it...

Additional Issues with 1000x

I have also purchased the Lexar 1000x 128Gb for my S7 Edge. It isn't crashing the phone, but I am seeing a notification of a problem with the card. When this happens, it tells me the card is not recognizable and will offer to reformat. If I remove the card and look at it on my computer, it seems fine. So far when I reinstall the card, it is then recognized and everything seems okay. I had initially assumed this was a memory card issue, but this is the second card showing essentially the same problem. Starting to wonder if there is a driver bug? I did not see this issue with a SanDisk Ulta 64Gb card I was using while waiting for the Lexar replacement. Does anyone have any thoughts on what is happening?
[Samsung Galaxy S7 Edge Accessories] C0derbear:
I had the Lexar 1000x 128Gb in my S7E also and had a few instances of it dropping offline, no file corruption - just all the sudden music could not be read or photos viewed or the like. Restarting the phone w/o removing the card would bring it back online.

I swapped in my older Sandisk 128Gb card in and so-far haven't had any issues. Too early to tell for sure but the Lexar didn't go a whole week without droping and the Sandisk has been in a week w/o issue.

I'm thinking the Lexar just doesn't have the stability it needs without the UHS-II connector set.

Sandisk is about 25% slower writing than the Lexar but about 90% same speed as reading, so still works well enough.

I guess I'll wait for a 200gb Sandisk or Samsung card before worrying about upgrading if this keeps up.
[Samsung Galaxy S7 Edge Accessories] Semseddin:
Been using this card since 1st day, no notifications of whatsoever unless i restart the phone. When it is about memory cards, sandisk is the standart.
[Samsung Galaxy S7 Edge Accessories] hboos:
I reformatted my Lexar 1000x 128GB in my phone and it worked fine for a few weeks and then it went to what you are describing here. I guess it's an improvement (I no longer have to remove the card to restart the phone) but I have to be careful of flicking through the files in my card in case it freezes.

I'm off to get myself a sandisk or a samsung card. Let me know if the problem resolves for you guys. Thanks
[Samsung Galaxy S7 Edge Accessories] flarbear:
These could also be fitment tolerance issues. Has anyone noticed any issues with the cards having free play in the sim card tray? Are they they thinner perhaps?

Hi everyone,

I was following this thread before making a purchase but got a good deal on a Mixza 128GB SD card from Aliexpress ($26) with free shopping so just placed the order and received it yesterday.

The card seems to be of good quality and works well. I almost filled it up half way through and doesn't effect any performance of the phone or itself.

I'm pretty satisfied with the purchase considering the price, would recommend for big capacity with nice read speeds and decent write speeds.

[Samsung Galaxy S7 Edge Accessories] william58:
How'd you get it so fast??? That is a Chinese brand and Aliexpress is also in China! Seen that company several time online. Time will tell. I'm sticking with SanDisk as I have for over 20. I KNOW they're good.
[Samsung Galaxy S7 Edge Accessories] markshane:
I usually purchase only from Aliexpress rather than eBay or Amazon as I find better deals and honest user reviews there with actual pictures and comments. I ordered around 20 items on 29th March (Aliexpress anniversary sale) and got excellent deals like Samsung quick wireless charger for $5 and other screen protectors, carbon fiber skins for S7 and PS4 etc etc and received almost 15 items already, some as early as within a week.

I've used a SanDisk 32GB Ultra and later a Samsung Evo+ 64GB in my Z2 for two years but this time I didn't want to spend a lot more on SD as I found this card to be equally competent to big brands. I hope it won't let me down for at least 2 years. Then I'll move on to 200GB or something...

[Samsung Galaxy S7 Edge Accessories] gx3k:
The truth is, most class 10 sdcards will do 4k as the bitrates for them are quite low (usually less than 10mb/s). It's more about the capacity than the speed. I record in 4k for over a year now and has not found a class 10 and higher card that wont record 4k (using note 4 and S7 edge). The only difference might be that it will take longer to take the next video as it saves but thats split seconds we're talking about. Not really noticeable in real life. I started making videos in 480p years ago and I sure hoped I filmed in the highest possible quality then even if I didn't have the telly to watch them in. Here's a shameless plug of my youtube channel that has been using 4k videos since last year: http://www.youtube.com/gx3k
[Samsung Galaxy S7 Edge Accessories] boolat:
hello, are you satisfied? for videos and pictures no slowdown?
[Samsung Galaxy S7 Edge Accessories] markshane:
Nope, no slowdowns whatsoever. I did a couple of stress tests to check the efficiency of the card by copying 45GB's of movies, videos and pictures along with some 15GB's of music, which it copied fairly quickly by the way at average 25MB/s, then quickly put it back inside the phone and loaded the gallery app to check how quickly it loads the icons while simultaneously reading updating the content and I was honestly surprised at the speed it was updating the icons as I was scrolling without any lag.

Also shot many photos and long videos with the phone and no problem at all.

Sandisk MicroSD SDXC 200GB on Samsung Galaxy S4 on

I hope this is put in the right section here, but I just wanted to tell you guys that on my Samsung Galaxy phone S4 (non rooted), a MicroSD Sandisk SDXC 200GB card (the new black one with red inscription) works flawlessly. So it's evident I guess, it'll work on higher models like the S7. .

It comes preformatted in ex-FAT, with 16Mb unallocated. Keep it that way.

What I did and to be on the safe side , I copied the content from my old, if upgrading from a lower size, in a 2-way process. Remove the card from your phone, put it in some card receptable, in your PC make all files visible (extra > folder options > view > uncheck protected files, check hidden files .. ) and copy the full content of your actual SD card in some folder. Copy all that content now to your new SDXC 200GB. Success !

Sd xc

I bought a sd xc card. And for some reason that card doesn't show 128 gb. I can't remember how much but it has 4 mb on it. Really strange cause my s7 can definitely read it. Any fix for this? Tried formatting it but no luck....

:(
[Samsung Galaxy S7 Edge Accessories] C0derbear:
I'd put it into a PC card reader and verify that it's formatted to capacity (minus a few gb maybe), that it is formatted using exFAT file-system, and that from the PC you can fully write to the entire card.

There *are* fake cards out there advertising high capacity but not in reality having the capacity, which is why I say that verifying the formatting and data access from a different device is worth the effort.
[Samsung Galaxy S7 Edge Accessories] TomDDD:
I had bad experience with a card bought on the internet. Indeed it was in the launch period of the 64GB one's. But I only detected it was a forged one after a year or so. Buy yours in a shop I'd say. Always easy to return it back. Oh and BTW an Ultra SDXC is fast enough. At the moment the extra you pay is not exactly good value 4 money.

Got a relatively old SanDisk Extreme 64GB. It's not bad, but not great compared to the newer cards but the. I got it dead cheap. I need a larger one, so I'm holding out till I see a good deal on a 128 Samsung Pro+.
[Samsung Galaxy S7 Edge Accessories] liobeir:
Can you explain me how to do these things? I will check this later and maybe send some printscreens
[Samsung Galaxy S7 Edge Accessories] flarbear:
How much lower? All cards have lower capacity than what is shown on the label due to creative marketing. A "64GB" card will tend to have around 60gb of storage when viewed in a computer or phone. A 128gb card might have only 120gb. This is usually due to measuring the card with powers of 10 for marketing materials, but computers measure them in powers of 2.

10^3 (1000) is not quite 2^10 (1024), but kb can mean either quantity

10^6 (1,000,000) is not quite 2^20 (1,048,576), but mb can mean either quantity

10^9 (1,000,000,000) is not quite 2^30 (1,073,741,824) bug gb can mean either quantity

128gb usually means 128,000,000,000 when they claim capacity, but measured as powers of 2 that comes out to be 119.2 * (1,073,741,824) so the computer claims it is 119gb

There is a move to use the suffix "GiB" to mean strictly "times 2^30" rather than "times 10^9-ish" and to leave the "GB" suffix to mean a power of 10, but that usage is not strictly adhered to in computing, especially for "info screens" when you examine the sizes of cards and drives.

There is also a bit of rounding in marketing, kind of the way that your 54.3 inch tv screen is marketed as a 55" tv, and then in the fine print you see them use the term "55 inch class" meaning "somewhere in the vicinity of 55 inches"...
[Samsung Galaxy S7 Edge Accessories] liobeir:

Having looked back at my results and redone the test a couple times, it appears this card has TERRIBLE random write figures...

[Samsung Galaxy S7 Edge Accessories] flarbear:
It seems to have roughly the same (poor) performance as the SanDisk 200gb Ultras. The sad thing is that it claims to be U3, but doesn't seem to exceed 30MB/s (sequential) in the tests you posted which means it is not meeting the minimum speed guaranteed by the speed class symbol written on the card. At least the Ultras only claim Class 10 (roughly equal to U1, or 10MB/s). Although I do note that the Extreme does have better sequential write speed than the Ultras, just not good enough to warrant its speed class rating, so if it just claimed U1 it would be set...

I don't know guys, all this waste of good time focussing on speed tests (they are really important in photocapturing equipment I admit). There are so much factors that depend on real life transfer speeds. LIke one or more files, size, from internal to external, copying or moving, etc.... I personally just tend to rely on vendor's specs. Of course if you you have specs like flarbear above that's a different story.
