I'm going to buy a 16GB microsd card from sandisk. I've been finding on Amazon and found these two products:
Sandisk 16GB Mobile Ultra MicroSD Card : £36.00
SanDisk 16GB microSDHC Memory Card : £15.99
I've also noticed they're all class 2 (can't find a class 4 or class 6 sandisk). So what is the difference between them? I'm using the card for Windows Phone 7, so which one should I buy?
Ha, i'm looking to buy a 16Gb card for my htc desire and I was looking at exactly the same cards.
As far as I found so far the ultra version seems to be class 4.
If you have any new info it will me much appreciated.
well in some pages you can find comparative boxes about those micro sd, i remember that microsd 16 gb sandisk (class4) is more faster than 16 gb kingtons class4 , so i supousse that this ultra micro sd is like class 6 real XD, i will find some information about it, oh plz don't forget that some devices don't support those kind of micro sd (an example htc hd2 has little bugs with microsd class 4, i have one...)
Sorry if i don't write well but i'm peruavian =)
Hey guys,
Can any of you confirm if Android is booting from Sandisk 16GB Mobile Ultra MicroSD Card ?
I want to buy one but i saw in forums that some cards doesn't work for this..
the ultra one has the better speed and more stable than the normal one. And, it has the same compatitablity.
So, if you are not concern about the price, the ultra one is the better choice.
Also, that should have the extreme III type, that is the best~
Go for the Ultra microSD, it's faster!! been using a 8Gig on my phone and damn its fast!!
16GB Sandisk Micro SDHC
I'm currently using 16GB Sandisk Micro SDHC (class 4) for my LG P500. It is fast & I have not encountered any issues so far.
I've been using Sandisk memory cards for other gadgets & I think it is one of the most reliable brands that is available in my location.
With sandisk/kingston, class 2 should be fine too. CLASS 4 might help recording high def video
Stick with the name brands and forget the Chinese non name brand off off of Flea-bay, they are crap and do not work imho!!
The more expensive cards are usually just higher speed.
I use fast cards in my DSLR to help when shooting bursts. Slower cards fill up, and drop the fps.
I'm currently using 16GB Sandisk Micro SDHC
Go for the Ultra microSD, it's faster!!
You should choose your memory card depending on what you're going to use it for. Either way, you should go with Sandisk cards, as they are the highest quality and produce their own chips. Kingstons should be avoided even though for some reason they are known as a quality brand... kingston just buys chips from other manufacturers and puts their name on them.... you will find many different kinds of chips inside kingston, so you will find more variation and defects from batch to batch.
As far as class, that is only referring to the sequential write speed. If you are getting the card for a digital camera, then a high class card is good, because you will be writing a lot of files sequentially.
But if you plan on using the card for WP7 or to run android of off, generally a class 2 or 4 card is better, because they have better random access speeds. The tweaks card makers do to make cards have higher sequential write speeds many times will lower the random access speed, so you will have more issues running WP7 or Android off of a class 6 or 10 card.
for 8gb ultra i got with usb2.0 card reader : 13mb/s write , 20.5mb/s read
I know the thread is old, but still.

I know thread is too old to write anything. But still (since google pointed me here)...
I've used both types of cards and have found that Sandisc ultra (Red & Black) is far better in speeds and reliability than the Sandisc simple/normal black colour chips. Also know that there are further/more better than ultra, called by Sandisc as extreme and Extreme Pro.
Also warranty for all is same: Lifetime. And Sandisc provided me a new chip within 25 days after my old 32 normal chip went faulty.
Re
I would always buy a class 10 card, because when you copy your photos it doesn't take so much time...
I discovered - the hard way - that "normal" class 2 or 4 MicroSD cards won't stay alive very long on Samsung Note 4 or similar phones... One day they stop working and all pictures and info is lost forever. The only MicroSD that can get the job done is a Class 10 UHC Sandisk card. I have used Kingston and all died only after a few months, specially if you install apps on them. They can´t handle the workload and you will end up losing everything you have on them. I have one of the red and gray Sandisk cards and it's awesome. It's fast and it's still working after 2 and a half years of use in a Sony Xperia Z2. Gotta love this little tough card.
I want to max out the memory with a 32gb SDHC. Anyone have any suggestions?
The SanDisk 32GB is very good,
it performs higher than stated with regards to class and obviously is a highly reliable make.

Another vote here for sandisk, havent actually tried their 32GB, but every other card i've had from them has been faultless.
Most important thing w.r.t. memory cards IMO, is to buy from a reliable source. Ebay is rife with fakes.
Arc can handle up to class 6?
Or i shall order a class 8 or 10.
When i bought arc i had in the case a 16gb sdhc card, but i want a faster one
someone was able to get between 6.00 to 6.79 MB/s on his Class 6 16GB MicroSD, but that was on an X10. you might get similar results on the Arc.
(source)
just got a lexar 32gb class 10 card from amazon (solutek) works great , faster than standard card supplied with arc
I guess I'll try the Sandisk, much appreciated guys. Now I just need this phone to be shipped.
I Bought a Sandisk Class 4 32GB and it works fine for me.
The data transfer to the card seems faster when I take it out of the phone.
I was thinking of getting Lexar MicroSDHC 32 GB Class 10 from amazon for my arc so anyone have it already and how is it? cus i didn't see any sandisk microsd have class 10 32Gb.
I've used the original Sandisk MicroSd 8 Gb (Class 2) and a Class 6 variant... When you copy big numbers of mp3 or movies to the phone, it really makes a difference. Example: with a Class 2 it takes about up to 1 or more hours to transfer 1 Gb - a Class 6 does the job in less then 5 minutes...! But if you want to buy a good rated SD because of the HD-camera, then Class 2 should be high enough (according to the experts). Any higher only helps if you transfer data a lot/often (like changing your musiccollection on the Arc).

btw, if anyone spots a good micro sd 16gb class 6 or higher please inform me.
I become a 16GB Class 2 Card but this card was wrong, the write speed is 3Mb/s, then I bought a new 16GB Class 10 Card. This card speed: 11.3/20.9 (write/read) the i am happy The maked HD video is better and the frame rate is really 30fps
UPDATE: The card worked much data disappeared from him then until 5 days. The next day the telephone did not see the card already though. F***ing noname card! Nobody let me not buy it trademarkless card!
hi everyone.
im looking to get the new note 2 and would like some suggestions for a the sd card preferbly 64gb one.
i have looked on some sites like memoryc for ideas but would like suggestions..
the prices ive seen listed are all within my budget so need a compatible fastest if possible 64gb card and which brands are the best? is sandisk still a good choice as i have seen samsung bringing out a new range and they are usually cutting edge last time i remembered.
for example is the new format compatable microSDXC??
"64GB Sandisk microSDXC CL6 Mobile Ultra memory card"
thankyou.

fastest card is sandisk extreme pro, but ur phone wont be able to use those speeds, plus its expensive. My suggestion is the sandisk mobile ultra, best bang for the buck.

I'm sure it's a similiar issue as it is with cameras.
Someone needs to do a sd card speed test to see what the read/write speed limit of the note 2's hardware is.
It's probably way under the speed of that SD card.
However, getting a faster card means you can transfer stuff on/off of the card a lot faster through your PC.
This is useful for copying movies on (or for cameras, copying off tons of pictures).

ill be using it for HD 720p movies + HD Video rec and photos too thats why i wanted speed for writing and copy from pc and for good rec/playback.
so ill stick to this then 64GB Sandisk microSDXC CL6 Mobile Ultra its a good price and should be good for what i need at 30MB/sec
thanks again
by the way i just noticed theres 2 which is the better as i read cl6 cl10 thinking it was like memory with cas speeds lower being better?

No!!!! CL = class, and higher should mean better.
CLX means the card is guaranted to read/write at X meg/second.
However, people have found that higher quality memory cards exceed their class numbers,so YMMV.

fixed.
Class 2 means minimum write speed of 2MB/s.
Class 10 means minimum write speed of 10MB/s
read speed can still be varied. It's also possible also to get class 6 card that write at 8MB/s, it just happen to guarantee at 6MB/s. Also I have seen like Class 10 SDXC(not micro) that can read at 40+ MB/s. I would read review at amazon and newegg to get the general idea b4 buying on.
Can anyone comment yet on the speeds they are getting with their internal microsd cards for read and write?
I would like to see if it is worth splashing out on an expensive high speed card, or because it is running USB2 that in real terms it is crippled to about 20MBps read/write. It would be a pitty if the speeds are crappy, as samsung is making some pretty sweet microsd cards these days.

ooops. you are right... a1 sd bench labels it wrong. It says Internal SD card as my external and my internal as my external. (Sorry)
Here's my new results - reading 40 MB/sec 14 MB/s write..
Once again - sorry about that.
Guys, when you say Class 10 you aren't really speaking to the speed of the card. There is a wide range of speeds in cards that are all rated as class 10. Samsung has some that are 90 read and 80 write for example and most only advertise as 30 read and don't even say their write. Anyone have one of Samsung's good 90/50 or 90/80 cards they have tested?
I have just benchmarked a 64GB Samsung Pro MicroSDXC card (rated at 90MB/s read, 80MB/s write). In a USB 3.0 card reader on my computer it writes at around 65MB/s average and reads at upwards of 80MB/s.
In the Tab S 8.4 (Wi-Fi only model) it benchmarks at 49.53MB/s read and 24.53MB/s write in A1 SD Bench
So what would anyone say... Is the best card for this particular device? Any recommendations?
If you're not planning on taking the MicroSD card out of the tablet in order to transfer content onto it, then you might as well just go for a mid-range card as it will be limited by USB 2.0 transfer speeds anyway. I'd say the Samsung Evo or the old Samsung Pro card would be fine depending on pricing.
I dont plan on taking it out. Since the above Benchmade had the pro at 49.53MB/s read. I feel It's just going to be overkill. Since its not getting the full 90 MB/s read 80MB/s write. I'm thinking the Evo should suffice. What are your thoughts?
I meant the old Pro model, which I think was 70MB/s Read - 20MB/s write, these can sometimes be had for similar money as the new Evo. I think you'd be fine with either of those, or even the Plus model. I think the Samsung MicroSDs are fairly reliable in general.
So nobody knows if Tab S has standard bus, high speed bus or Ultra High Speed Bus UHS-I or UHS-II?
I think that micro SD card Class 10 U3 guarantees minimum 30MB/s. So it supports even 4K recording...
But I still don't know if it is worth of a lot of money. If benchmarks are true - Tab S has UHS (your 45MB/s). If!
bus speeds

According to Samsung support, the Tab S micro SD speeds is limited by the USB 2.0 bus, or 60 MB/s. So that would imply UHS, though the 90MB/s cards would not get the full speed. I would like to see someone test a 90MB/s card and see what the results are. Probably just going to go with a 48MB/s card if there isn't any difference. Though I think write speeds are significantly different between the higher speed UHS-I cards and the lower speed ones (50 vs 10 MB/s write I think).
If anyone has a couple cards and a Tab S they can test with, I would love to see the results.
I know, this is probably a silly question, but am I the only one that notices how devices only tend to label compatibility with Micro SD cards based on size, and not speed or class? For instance, my Galaxy Tab S2, it simply says it can take up to a 128gb SD card, but it does not say what speed it will work with.
The reason I ask, is that I am now in the market for a 128gb card, and yet I don't want to buy an expensive fast one, if my tablet will not be able to take advantage of the premium speed. Anyone have any thoughts?
I don't know about the speed but I have a SanDisk 200 GB that runs fine.
I think that any phone or tablet that will read 128 GB will also work with 200 GB.
Shofar
Don't worry
Any MicroSD card will work in your Galaxy Tab S2. But then, you might have to format it. When you buy the card, keep an eye out on the speed class- higher speeds are much better!
You are looking for a 128GB card, and I use one in my tablet so don't worry. It will work! But I seriously recommend a higher performance card because it can get very slow with cheaper cards.
Hope this helps!
I just tested a regular class 10 card and a UHS-1 card. Both tested at 9mb write and 40mb read. The same UHS-1 card tested over 40mb write using an Odroid C1 board.

No, that means that "class" classification is outdated. Fast cards (read and write) bear the UHS-I "U3" classification, "U1" is slower.
In future, only buy U3 cards, like the SanDisk Extreme family.

I guess you missed the part where I stated that the UHS card had a write speed of 40mb using the Odroid C1 board. Obviously, when it only writes 9mb in the S2, then the S2 itself doesn't support the higher speeds. So, no matter ability the card has, if the device's bus doesn't support the higher speed, then the card's ability is meaningless. Any card you use is going to be limited by the bus speed of the device.
Paying extra for a better card is pointless if the device doesn't support the higher speed.

This was what I meant, I'll make sure to buy a decent one but not the "best". Quick question, how are the internal memory write speeds? Actually, what card should I get then? How fast is the internal memory write speeds? Thanks!
Just tested the 32 GB SanDisk Extreme (U3 but not an Extreme Plus or Pro) in my T815 with the "A1 SD Bench" app:
read 59,70 MB/s or 61,04 MB/s, write 22,75 MB/s or 24,70 MB/s. The second numbers are the result of using the "accurate mode" of the test app.

For our fast S2, this one is too slow in writing. Class 10 means only fast reading.
You better choose a Samsung or SanDisk with the "U3" designation, which means fast writing, like this:

FOR EVERYBODY :
I have bought a LEXAR 633x 200GB !!!
And it works !
Speed : read 95Mo/s write : 40Mo/s
For 90$, it do the job very well !
The only better sdcard is the 256GB SAMSUNG but it's out of price !
So a higher performance card or 200GB eill make the tab s2 go faster then? What amount of storage and sd card do you recommend?
It won't make the tab S2 go faster. But it will allow faster read/writing to higher performance sd card compared to a regular one. The S2 can only go as fast as it's hardware can, with or without a microsd card.
Figured I'd share my results with my 2015 S2 8.0 (SM-T710). Right now I have a Samsung EVO Pro (U1) 64GB in my tablet and it does ok, but I'm just about to upgrade it to a new 128GB EVO PLUS (U3) card so got some results below. Note the previous 32GB card I had was waay worse, much older and only did 4MB/sec on writes (forgot the brand) but things have at least come a long way in the years since.
Results as follows...
Samsung EVO Pro 64GB (U1) - 70.53MB/sec Read - 72.86MB/sec Write (Fresh Format)
Samsung EVO Plus 128GB (U3) - 69.91MB/sec Read - 43.40MB/sec Write (Fresh Format)
Samsung EVO Pro 64GB (U1) - 70.07MB/sec Read - 17.81MB/sec Write (Only 4.9GB Free)
Samsung EVO Plus 128GB (U3) - 63.08MB/sec Read - 27.12MB/sec Write (Only 65.9GB Free)
For the heck of it tried the transfer rates on the PC for the 2 cards as well.
Samsung EVO Pro 64GB (U1) - 86.85MB/sec Read - 80.77MB/sec Write (Fresh Format)
Samsung EVO Plus 128GB (U3) - 87.04MB/sec Read - 82.27MB/sec Write (Fresh Format)
Though got to say while cards neck and neck, small file writes where 5x greater on the new U3 card (.5MB/sec vs 2.5MB/sec) on 4k writes.
