Is a microsd class 2 enough for recording hd videos and running apps?

Im planning on buying a 16 gb microsd card but all i can find is cards class 2 is that enough for recording 720p and loading applications installed to the SD card ? keep in mind that i also plan un buying a optimus 2x which has 1080p recording
Which brand do you like better? sandisk? kigston? trascend?
I read that sandisk class 4 cards are REALLY good but they dont show up in their website or amazon :/ , it seems they only sell class 2 cards, and kingston offers cards class 10 and 4 , class 10 seems a little excessive

Class 4 but really class 6 is what u need class 2 will die

yeah minimum a class 4
class 2 is just a pain, it will make you want to throw the phone away, and explode it into a million tiny bits
class 6 is the normal speed for a fluid experience

Im using a Sandisk 32GB class 2 card, it writes at 5~7Mb/s depending if its a large file or several smaller ones and read as higher than 15Mb/s

class 2 will die? u mean its on its way out?
Ive been reading good comments about the sandisk cards, but they only sell class 2 cards :/ , what brands are u guys using?

If you are getting a 16gb card, or less sandisk, kingston or toshiba, class 2 or class 4 offers similar read/write speed, although the toshiba and kingston is a little faster, the sandisk is much stable.
Read is about 11-14mb
write is about 8mb
I had a toshiba 16gb class 2 in my i9000, it plays 720p videos without any problems, now i am using a lexar 32gb class 10, results aren't any different.
Hope this helps.

lexar 32gb class 10? jezus christ you must have payen an arm and a leg for that ****.

Approximate usd 85.

The class designation of SD Cards ONLY represents the sustained WRITE speed to the card in MB/s. So, class 2 means it can be written to at 2MB/s, while class 10 means it can be written to at 10MB/s.
The designation has no reference whatsoever to the read speed of the card. So, basically every response stating otherwise in this thread is wrong. You should be able to get suitable sustained read speeds out of any class 2 or higher SD Card for the purposes you will be using it for. It will just take you longer to transfer the data to it in the first place. As for video recording from your phone, class should should be plenty as I'm pretty sure 720P comes in under 2MB/s.

Wow, yea. Just that i seen some online shops which class 2 32gb cost 100$
But on amazon the lexar class10 32gb is really cheap...
http://www.amazon.com/Lexar-MicroSD...610M/ref=sr_1_1?ie=UTF8&qid=1296152464&sr=8-1
Anyway, i got a 16gb class2 card (a-data) and i can play 720p and record just fine...
Electroz is right. Its only about transferring and stuff.

The speed of the card used in the phone does not make much of a difference, its onlt when you transfer data to and from Pc, but its always best to get the fastest available, if the budget is the main problem, consider getting a kingston or toshiba, but make sure you get one that is made in japan, as the taiwan version is a litttle slower, japan version are becoming harder to get now, since the japan factor has transferred their production to the taiwan site.
The classes stated on each card is only the minimum it will reach.
Class 2 at least 2 mb read/write
class 4 at least 4 mb read/write. etc.
So it can be anything above the actual figures.
For more info on microsd, see my link in the sig, although its a little out dated.

The actual retail price for the lexar 32gb class 10 is 149 usd.

No problems with 32GB Class 2 here, it can record and decode 720p just fine, and there is nothing else as intensive as those tasks that you'll be doing with this handset (may not be enough to support 1080p in future handsets, but that remains to be seen).
Don't buy into this rubbish about needing Class 4 or 6 cards, unless you regularly load very large numbers of small files to your card, in which case you may want the higher write speeds.

when you run apps and/or games off the SD (App2SD) the slower the card the more time it takes to have a fluid experience, specially heavy stuff from gamesoft, or simply opening the application manager and waiting for the icons to load
repeat the same tasks with a slower card vs a faster card and you'll see the difference
of course you'll not really see much of a difference, unless you card is more than 50% full, and have over 300+ apps installed

You can buy a Kingmax 16GB Class 6 at Amazon for £43. I didn't had any problem to find it. Class 6 is much better. See you - Frank

so at £43 pounds i easily get 2x Adata 16 GB class 6
which i already have many (each of my 5 phones has one, plus another one on the video camera CountourHD 1080p), and they work really good

If your getting cards from a non generic name brand, the read speeds should be around 15-25Mb/s , My class 6 card actually had a slower read speed of 15Mb/s compared to my Class2 ( 28Mb/s )
At the end of the day the difference between loading something was barely noticeable even skipping to different portions of a 3.7GB movie, Im guessing the phone it self is the bottleneck and not the card.
1% or 99% full should have ZERO effect on the read/write speed this is not some mechanical drive nor having 1 or all the apps in the market.
EDIT:
Again the class rating is only a rate on what is the minimum write speed the card can handle, sandisk rates their 32GB at class 2 when it writes at 6-7Mb/s ( making it class 6 ) on the phone and about 10Mb/s using a card reader ( making it class 10 )

yeh, buying from a local store is cheaper, from the same price of a kingston 16gb class 10, you can get a 32gb class 4, but the fastest microsd on the market is the kingston 32gb class 10, but stock is very limited due to high prices, and you probable need to place an order and pay in advanced, i'm still searching for one, since the last time i heard about it about 9 months ago.
adata are the cheapest cards now, but the speed are rather slow, compared when they only released the 8gb about a year ago.

Is A-RAM a trusted brand? (SD CARD)

I've been looking at this... (Class 4)
http://www.scorptec.com.au/computer/40130-arsdmcl4-32gb
I have no idea who A-RAM are... but its being sold at a real computer store not ebay so its gotta be legit?
Or I could get this... (Class 10)
http://www.scorptec.com.au/computer/40129-arsdmcl10-16gb
But I think I rather the space.
Another quick question, how do I rate my current (8GB) SD card and find out what class it is?

Er, a bump...?

Personally never heard of A-ram but that doesn't mean it's necessarily inferior, why not ask the retailer to provide some benchmark figures for you?. Personally I'd buy the fastest, not biggest card you can afford so would go for the class 10 16gb one.
Try sd tools from the market to bench your current card.

I used to work at PCCaseGear, whho also sold A-Ram, never heard of it before, but the 16Gb Micro SDHC i got performs as fast in a disk test as the nokia 8Gb that came in my N8 before i jumped ship to android. hasn't died yet...

I've used A-Ram before...
Never had a problem with it.

With memory cards I find myself a bit suspicious (bought one a wierd branded mem card for my PSPS and it busted with all my saves...)
Personally I would go for Kingston, Sandisk etc... They also have almost always a 5-year-warranty. I actually just ordered a 32gb Kingston Class 4 couple of days ago.
With phones I would go for size rather than speed. I would get class 10 for a good full hd vidcam or system camera, but not for a phone.

size and speed help, my 32 Gb has a pretty slow write time, which kinda sucks when copying new roms or tunes over. almost considering going back to the smaller but faster a-ram 16gb, solely for write speed.

Ive been using one I picked up from a shop in Aus, a year old now and still runs but some files do go missing... going to buy sandisk from now on.

Dude, a Sandisk Mobile Ultra would pi$$ all over that class 10 card.
WAY too may perople assume that coz, say for example, a Samsung, Patriot, PNY, or whatever make it is...they assume because it is a 'class 10' card.....that it's better and faster......WRONG!!
I have looked into this in GREAT detail......and Bring a Class 10 Samsung, PNY, Kingston (or whatever) to the table......and a Sandisk Mobile Ultra CLASS 4.....yes, CLASS 4, will pi$$ al over the other makes of class 6, 8 and 10!!
I was out looking for a new card and size was not the issue as I hardly ever go over 2-3gb of storage.....so I could of had a PNY Class 10 card for around £20.00.......but instead I went for the SANDISK MOBILE ULTRA CLASS 4 ! !
I've got a couple of old class 4 cards here (NON-Sandisk) and also benchmarked it against my mate's Samsung class 10....
....My little class 4 sandisk mobile ultra BLEW them all away.
please please please don't get any old make, just coz it says "class 10".
Sandisk = the best. FACT!
Here's a Benchmark test result from a very reliable source.
Check this out, very good read:
http://www.tomshardware.com/reviews/microsdhc-memory-card-performance,3011-7.html
"The US-based manufacturer SanDisk is, according to its press releases, the largest manufacturer of flash-based products in the world. Befitting this position, SanDisk offers a complete portfolio of memory cards. The company presents the microSDHC cards on its site’s Mobile Memory section, aiming them at owners of smartphones.
The Mobile Ultra microSDHC card is intended for transferring files between a mobile phone and a PC, which is why it comes with a USB card reader. We tested both the 8 GB SanDisk microSDHC card and the 16 GB SanDisk Mobile Ultra microSDHC. According to the manufacturer, both are Class 4 products.
Class 4 is a real understatement for the Mobile Ultra microSDHC model. Defying its designation, our test sample ran rings around many of the Class 10 cards and exhibited good to excellent read and write performance in all benchmarks. Clocking in at 22.8 MB/s, it even took the lead in our sequential read test. However, it is not quite as fast in the sequential write benchmark, achieving 15.8 MB/s. The card also demonstrates very strong random read and write performance, again winning first place in these categories.
The 8 GB SanDisk microSDHC cannot quite live up to the results demonstrated by its fast Mobile Ultra brother. It really is a Class 4 card, clocking in at 11.6 MB/s sequential reads and 6.1 MB/s sequential writes. Compared to other Class 4 cards, it is fairly slow. Interestingly, the Class 4 Silicon Power microSDHC memory card exhibits precisely the same speed in all benchmarks.
Best part is.....got it at Argos.co.uk for £9.99.
Comes with card reader and software!!

thanks for the info about this tolls, is a very interesting app

32gb MicroSD advice please

I am looking at either a Lexar or Samsung both class 10, both around £37.
any advise as to which one is best based on anyone using.
The other question is do you need to format before use?
At the moment I have a 16gb but it is 98% full. Never chenged a card before was planning to copy the old card into a folder on laptop and then back onto the new card.
Any advise welcome,,,,,,,,

Go with transcend. If they have 32gb class 10.

They only do a 16gb class 10. I looked for Transcend first as I prefer this brand.....

I like transcend more than anything else.

I never had luck with transcend, i have a sandisk 32 gig which works great,
i had a kingston 32 class 10 within a few weeks it just burnt out on me it stop reading and wouldnt want to format or anything

I'm also looking for a 32gb micro sdhc for my HTC Vogue. I currently have a Sandisk 16gb that is nearly full. Earlier today I stumbled onto this thread from here at XDA...
http://forum.xda-developers.com/showthread.php?t=1150369
I found it quite helpful. I hope you do too.
I was surprised that class 10 cards weren't the best choice for the things I use my Vogue for.
Here is a passage that surprised me...
"Class 2 and 4 cards have better random access speed and random read/write than class 6 or 10 cards in general. To get higher sequential write speeds, manufacturers sacrifice the random access speeds.".

I would agree with Random read/write access might be better in Class 4 cards than Class 10...
But arent we forgetting that most of the applications are read more than Written when u open it.. I think a faster read speed with lower write speed would still be better than having lower read/write all together...Not unless you are downloading a torrent in background and running HD game with it... infact in that situation.. both cards will fail badly..

I prefer Sandisk.
A class 4 should generally give proper performance... 10 seems a bit overkill imho.

I've used the 8GB class 4 memory card that came with the Sensation for a while, and after switching to a 32GB class 10 Lexar I must say - it DOES make a difference. It's a totally different experience.

Been using SAMSUNG ESSENTIAL 32GB MicroSD for more than 2 months without issues. It has helped me to parallely download videos from tubemate in high speeds. Good writing and reading speeds. No slowdowns/jatter in 1080P recording which iam always using to cap my child.

Just bought a 32GB Class 10 Samsung card from play.com for £34.99. Working great so far!

I got the 16GB SD card for two reasons
1. The 16GB has a faster write speed.
2. I didn't have $90 to spend on the 32GB.
http://www.samsung.com/us/computer/memory-storage/MB-MPAGA/US?from_mobile=true
Oh also I did not pat $55 for the 16GB

Lexar or Samsung 32gb MicroSD Card Recommend?

Hi guys i am looking to buy a 32gb Class 10, MicroSD card for my Desire, i am planning to partition it so i can have more internal space. After searching the market for a competitive price, i have came down to 2 options:
Lexar 32GB Micro SDHC Class 10 Extreme Speed
Samsung MB-MSBGAEU 32GB Class 10 Micro SD Card
I would appreciate if users here can recommend me which one i should go for and why (if owned either and used) ?
Thanks alot

As far as I know, many of the higher class cards have been produced by biasing performance to continuous read/write speeds, for use in camcorders/cameras etc so they can record ultra HD or burst capture etc. HOWEVER, for use in a phone, which needs greater random read/write access they can suffer compared to a regular class 4 which is a better balanced card. There is a lot of this going on in the HTC Mozart pages here on XDA, where I've been spending time (had a Mozart, ROM'd it and gave it to my girlfriend, she loves it).
Many people have tried different 32gb/16gb cards, different classes from 2-10 and the results have been surprising. WP7 seems to be unusually fussy about the cards that will actually work with it, and the only card guaranteed to work everytime is SANDISK which says a lot about the quality, and people have been finding that performance with a Class 4 SanDisk card is better than performance with a supposed Class 10 card by another manufacturer such as Integral, Transcend etc or even Samsung and Kingston.
In the end I bought a 32gb SanDisk Class 4 off Amazon, for a lot more than they are on eBay at around £28, apparently there are loads of near-fakes on eBay (only way I could guarantee it was genuine- the chinese are using genuine 4gb SanDisk cards and then re-branding and re-coding them as 32gb, the card thinks it's a 32gb, reports that it's a 32gb card but obviously runs out of room and has errors as soon as you try to put stuff on it).
Hope this helps- generally you get what you pay for and if it sounds too good to be true it usually is.

I bought yesterday a samsung class 6, 16 GB micro-sd card.
H2testw:
Writing speed: 10.00 MByte/s
Reading speed: 15.5 MByte/s

i know this post is about 20 days old, but maybe you haven't choosen a sd card yet
i first got a 16gb lexar class 6 card -> everything was fine
now i got a 32 gb samsung class 10 card
and i must say there is no remarkable speed/transfer difference
so buy a card which is class 6 or higher and everything should be fine

I think I have fallen foul of this, I bought two 32gb cards from'micro sd cards uk' @ about 15 quid each and I cant write to them properly they are class 10 so they should be ok but I have nothing but probs with them on two laptops with different cards readers,
Ill contact the vendors tomorrow Ill keep you posted.

Sounds very cheap for a class 10 32gb card, I bought my samsung one around christmas for £35 and that was the cheapest price at the time!

I thought that the maximum allowed for Desire was 16 gb. Mine is 16 gb (Samsung), with good data transfer performance. By the way, in your situation I would go for Samsung.

[Q] Is pulling from micro sd card as fast as internal memory

(1) I'm going to buy a galaxy s4 when it comes out. I know it would probably be cheaper to buy the 16 mg version ,then buy micro sd card.
My question is does the phone work faster from the internal memory or does it pulll info just as fast from a micro sd card?
(2). Would sandisk extreme pro be a good choice ?

just make sure you get the ultra class 10 as it has faster speeds than the lower class cards
put the things that need to pull up fast on the internal memory like apps and put everything else on the card like music and things you wont notice a difference on

Not always true. I recommend reading benchmark test on the card you want to by and its competitors. I've seen some benchmarks where a Class 6 Sandisk beat out a Kingston Class 10 in the past in "some" writing areas.

I had a nightmare with sandisk in general both in my dslr and GS2. I use Lexar now and never had one issue. Sandisk has great customer service though. Refunded all 3 of my pro cards.

If the Galaxy S4 supports the UHS sdcards (45mb or 90mb read/write) then that would be as fast as you need imho.

This is extremely true! Never trust an SD card by what the claims are on the box. I have purchased many SD cards (all brands) over the last couple of months. 6 class 10 Sandisk all 32GB from different sources (Amazon, Best Buy, Radio Shack, etc...) and none of them benchmarked in at class 10. Most were between class 4 and 8 write speeds with read speeds being a bit better. 2 PNY 32 GB class 10 cards. Both of those tested above class 10 performance but died within 2 weeks. I have not been able to find and Amazon Basics 32 GB Class 10, but the other Amazon cards I have tried have worked well. Samsung cards seem to work well as well, but I have not benchmarked any of them. It really seems to be a crapshoot if you get a good card or not. Each specific device seems to like some brands better than others. Also, there is a huge (and I mean huge) problem with counterfeit cards and misrepresented (changed) class of cards flooding all markets. So good luck and let everyone know if you find a good card.

I also would say, download and do a full write format on the card with sdformatter https://www.sdcard.org/downloads/formatter_3/ prior to use. I have gotten many 4 speed cards to record hd video on my t3i just by using that software, when a regular format won't work.

If the Galaxy S4 supports the UHS sdcards (45mb or 90mb read/write) then that would be as fast as you need imho.
