How do you tell card class? What is the class of card that came with the Thunderbolt 32 gigabytes?
They usually have the class printed on them. Classes are 2, 4, 6, 8, 10, and UHS1 (SDXC). Most cards that come with phones are class 2 or 4. The number is usually printed in a circle.

Hi,
Any advantage to using a higher class on the note 2.
Thanks,
Bryan

The class refers to the minimum sustained read/write speed the card is capable of. So a class 2 card can handle 2 MB/sec or higher read and write, Class 4 is 4 MB/sec, and so on. You could get a class 2 card that is capable of class 10 speeds, but there are no guarantees of it. The faster speeds will be good when something is reading/writing data to/from the SD card, think Gallery and Camera being the two big ones. It would be able to load pictures faster for gallery, and save the faster when taking them with the camera.
If it isn't printed on the card, move files to and from with windows and note you're Transfer speeds

From what I know our 2gb SD card is class 6.
It may not be class 6 but it certainly isn't class 2 because the transfer speed is pretty good and problems would have appeared.
the card which comes with the phone is class 2
class 4 will be faster, class 6 will be even faster. (write and read)
The default card made in taiwan is class 4 or may be 6 the speed are higher around 5 mbps. But some cards are faulty. The class represents the mbps speed of the card like class 2 is 2 mbps class 4 is 4 mbps class 6 6 Mbps. Theres app called sdtools in market check it out. ( test sdcard and see what write speed it shows )

I got 8.6mbps write speed with SD Tools benchmark... Does this sound like a calss 2 card to you? I've had class 2 cards before and I'm pretty familiar with the slow speeds of those; this one doesn't compare.
If there is no number on the card within a circle then generally it is a class 2 card.

based on what I've read for the past couple of months many users have class 2 which had resulted in various problems. my speeds are around 2-3. and there's no number on the card. class 2. I'm getting an 8gb class 6 soon.
They provide different class of card to everyone. Some r lucky some not.

ok, thanks, so i will keep my default memory card.
for stats.
Writing speed: 6.5 MB/s
Reading speed: 17.8 MB/s
no class number on card.
Just how accurate is SD tools? I tried it on a 8gb transcend class 6 card and am getting
write - 11.7 mb
read 21.4
That seems pretty high right?
Well the class shows the minimum speed. So if you get high speed good for you.

Well, mine was class 0 a.k.a. no card included. Well, I do not complain since I got this brand new phone from Portugal for like $200 with a 2yrs warranty.
Then I bought a cheapo A-Data 8 GiB SD card and turns out I got this - quite happy if you ask me.
Just don't be happy about speed it's good but there's also latency (the root cause of reboots some users have).

Does any one know if Class 4 sd card work on vibrant. Im about to buy an 8gb class 4 sd card and wondering if anyone has or currently using a class 4 sd card on their vibrant?
Thanks.
Been using a 16Gb Class 4 Kingston MicroSD since I bought the phone, works perfectly. I dont see any reason you could not use a MicroSD up to class 10, even though it would be a waste of money. Class 6 is probably as high as you would want to go for performance/money sake.
thanks. just ordered a kingston 8gb class 4 micro sdhc for 12$
Fyi, the card that came with the vibrant is class 4

My class 10 Patriot 32GB loads about as fast as my class 6 16GB lexar if that means anything. Both open up quickly for music apps or gallery. Its just the initial reading after any boot that takes about a min or 2. Hope that helps reassure!
I have a 8 gb class 4 sd card in my evo 3d and i play alot of games that require downloaded media. I am ugrading to a 16 gb, would a class 2 be good or should i try for a class 4 or 6?
I plan to try out boot manager(the multiple rom thing as well)
The higher the class, the faster it reads your memory.

Look at this, 32gb class 4 $34.99. Also, what he said ^^
the phone runs around a class 6, so get an sdcard at least that high, I have a 32gb class 10 and couldn't be happier.

What he said. I just ordered a class 10 32gb Samsung for around 70 bucks with a good warranty. I have a 16gb class 6 now and its a definitely a noticeable difference from the stock class 4. It'll be definitely worth it to get the higher class sd.

It affects the performance this much |_| ...you decide.
Your card might be a class whatever. The output of:
/sys/devices/virtual/bdi/179:0/read_ahead_kb
and
/sys/devices/virtual/bdi/179:16/read_ahead_kb
affect the read ahead performance however. The card by itself is a load of old ****.
Ignore the people who have bought themselves a big waste of money.
Huge difference. Stupid serial access synthetic benchmarks as detailed above are of no relevance. Of course faster access medium is better. Like the difference between an HD and an ssd. Anyone saying otherwise has no idea what they are talking about.

Don't be ridiculous. Why not go on and argue that a 2mhz processor is just as good as a 1.4ghz quad core one? Simple logic and a very minor understanding of science will confirm it.

Rubbish. Of course a class 2 card is slower than a class 10. Proof? Look at any benchmark or try it yourself. Your argument is akin to arguing that a car with a top speed of 100mph and 0 to 60 of 20 seconds is just as fast as one with a top speed of 200mph and a 0 to 60 of 5 seconds. Get a grip. God there are some muppets on this forum....
It was to my understanding that a class 2 means that it will at least write at 2MB/s. It is by all means not limited to 2MB/s. Am I wrong?

The card doesn't control the read-write rate. The ROM does.
You are correct though. Example: A Lamborghini will do, let's say 180 mph... but the driver may never go above 50.
EDIT: I'm looking forward to seeing Dr Pepper's stats and data though.

It doesnt affect the performance because all if the phones data is stored in its internal Card which is much faster than any external card

See.. Cards performance will only be affected if you store game Data on the extsdcard.. Even then class 4 would be good enough.. If you don't want to buy class 10 buy a class 4 sdcard.. You won't notice any major speed differences

If you're recording hd video onto your card then you'll be better off with a class 10. Other than that, it won't affect the performance of your phone at all if you get a slower card.

I've had lags+stutters while recording video at 1080 and superfine quality directly to my class 6 SD card. Those videos were quite long (10-15 min).
Changing storage location to phone memory removes all the lags. I'm planning to change mine to class 10 soon.
Other than this, I don't see any real performance issue with lower class sd card; at least for me anyway.
Hi all
Which class of MicroSD you are using for better performance for Song/Apps/Video for your HTC Desire X?
I hope Sandisk Class 10, 8GB should be enough.
What do you say?
I finally placed a order of Sandisk 16GB, Class 10 card.
I'm using a class 4 sd card. Never had any problem with it

But if the maximum supported Class is (for instance) Class 2, I could save some money buying a Class 2 SD instead of a Class 10.

I've got no problems with a class 10 SD card as well. Mine is also supporting UHS-I standard, so it's even faster. I recommend buying the fastest SD card that's working with the device to avoid lags in apps / games you moved to the SD card.
