I got a 32GB sandisk card recently and it is class 2.
I think means its read speed is 2MB/s
So if I have a video encoded at a bitrate of 2500 kbps. Does that mean the SD card is too slow to watch the movie off the memory card?
How about something thats 5000kbps? I'm not sure how that translates into how fast the SD card needs to be.
It writes at 2mb/s it will be fine for an hd movie almost all cards read at the same speed regardless of class

On another related note doesn't the SD card buffer onto a part of the phone memory and play from there? Therefore making the speed of the SD card not as important?

From what I understand I would need the class 10 card if I want to record HD video. If I am not going to record video can I get away with class 4?
Thanks for any help!
You do not need a class 10 to record HD Video, a class 4 does the job perfectly well. I had a 32GB class 4 sandisk and it was fine.
I've heard that for smartphones, Class 10 is even worse than lower classes.
That's because class 10 has fast block reading speeding. The problem is that it comes at a price of slow random access reading. If you want to play high bitrate movies from the SD card, higher class will be better for sure. However for day-to-day usage, lower class might make the phone feel faster.

class 4 is good enough for video recording.
iirc, 1080p video on the note is recorded at a bitrate of around 17mbps or so. convert that from bits to bytes and its something like 2.125mb/s minimum required to record videos at 1080p. so anything higher than a class 2 should be fine for playback and recording (unless you encode at a silly bitrate).
the only time i could see anyone really needing the faster class speed would be if you wanted to take 8mp shots in rapid succession. depending on the colour tone of the image you intend to take, the file size can go up to 3mb. at that point, your photos per second will be limited by the speed of your memory card. ie. class 4 = 1 photo per second, class 6 = 2 photos per second, class 10 = 3 photos per second maximum.
Be careful in stores. Went to best buy last night for SD card. Class 4 cards only in phone section but at class 10 price from camera section. Also shelf had classes mixed up only sorted by gb. So pay attention to what your getting

Whelp, I know that my bullcrap cheapo Lexar "class 10" wont allow me to record to it directly.
Man.. I'm pissed. time to look for a new one.
Hope a Samsung 32GB c10 I am thinking of buying will be ok on a SAMSUNG device...
microSD Class 10
What about if you will move (apps2SD) games like Sentinel (TD game) in the microSD, is it necessary to go for c10?
I'm confused on what to buy, c4 or c10.
Need your help!
For me it is. copying movies from PC to my SD card is just painful on class4.
I see that some good class10 cards can write at 20mb/s (sequential), which is 5 times as fast as my current class4 sandisk (4.1mb/s).
The only thing that is holding me back is the price. Once the price comes down a bit ill definitely grab a c10 kingston 32gb.
What about for games you move to your external sd card? Will performance decrease with a c4? Much better with c10?
What can you say about the Ridata 32gb class 10? Is it any good compared to transcend or kingston or sandisk?

Dont know about games, I doubt c10 will make a difference at all....but dont mark my words
As for brand you should look at the particular model rather than judging by just the brand. For instance the sandisk mobile ultra (class 4) beats many of the other class10 cards

I managed to get a class 10 32 gig for about £25. Currently they are very cheap so it might be worth getting it either way.

When I switched from a class4 32GB sandisk to a class10 32GB Lexar, I noticed the smartphone working faster and snappier, probably APP2SD in gingerbread and pictures and videos in the gallery has something to do with that change in response.
In my experience with memory cards and professional equipment, not only we shall choose for class ratings, but also for trusted brands, like sandisk, lexar and transcend.
To sum up, class10 is better than class4, and if the diference in price is not very high, totally worth it, but, there is a lot more difference in daily use between a galaxy note and a HTC Desire.
Class 10 is for marketing, it's totally not needed for smartphone with internal memcard.
You might want to read this thread on why class 4 is better suited for smartphone use.

Can someone answer the following question which 32gb SD card is best for Samsung Galaxy Note in terms of performance?
Assuming there is one simple answer
Would appreciated a direct link to say Amazon product page.

Sandisk 16/32GB Mobile Ultra
Guys!
What can you say about Sandisk's Mobile Ultra microSD cards? I'm planning to buy this sdcard instead of class10 microsd cards.
Thanks!

probably the best , but superexpensive
Currently I'm using 16GB class4.
Thinking to changing 32GB class10.
Does class10 makes a difference in recording 1080p videos? And what sort of differences will it make?
Thanks.
Speed class 10 which is a high speed bus. Basically I think it'll be a lot better for you. Full HD video recording and HD still consecutive recording. Class 2, 4 & 6 are normal bus cards which include full HD vid recording also and SD video recording. There is a difference and 32GB is the way to go in your case.
Hope that helped
As the person said above, it's just the bus speed. It's not really going to make a significant difference with HD video. You might see it with contentious snap shot, but I don't believe the GN2 is setup for a fast enough rate.
The class10 is what professional photographers us in their cameras because of the access and write speeds. Their DSLs can take a couple shots per second. Then again, their cameras can cost several thousand dollars, versus the all in one device such as GN2, which essentially a fix point point and shoot camera when using the camera.
You probably see a little fast in transferring files around form the phone to the SDXC or SDXC to PC. Luckily the GN2 does have the hardware to use the class 10.
Personally, if you can get a class 10 on sale, like the other day with the 64GB class 10 Scandisk Ultra for $45, I would. The cost is the same as that as of class 6. Given the phone and limited build in storage, I recommend a 64GB over a class 10
Hello!
I want to buy a memory card for the G4 and it needs to handle 4K videos without any issues. Do I need a class 3 USH-I card or is class 1 enough? Just can't find any answer to this.
Thanks.
I am using a Class 10 Sandisk Ultra 16Gb card with the 60Mbps camera mod for 4k with no issues thus far with recording.

Alright, just a regular non UHS card? Sounds like a quite basic one should be enough.
Btw, do you know a good app that converts 4K video to 1080p video?
No matter what you buy, but make sure to buy an original SD card. These days, eBay and Amazon is flooded with fake chinese cards. I've been cheated by eBay and its seller when i purchased Samsung UVO UHS-1 Class 10 card. The eBay sided with seller.

Hi there! I'm going to buy a MicroSD card for my future LG G3 for long 4k videos recording, but before that I have 2 questions:
1) Does this phone support 4K video recording directly into external MicroSD card??
2) What card would you recommend to buy for smooth 4k video experience? Whether I required to buy Class 10 UHS-I Speed Class 3 (U3) card with 95MB/S write speed or it will be just enough to take Class 10 UHS-I Speed Class 1 (U1) card with 40MB/S write speed?
Thank you in advance,
Vadim
4k on G3 use 30mbps = 2,8MB/s. Class4 it's OK.
