Hi guys, I am about to purchase my galaxy note next week and I was wondering if anyone could shed some light into the matter..
Which class of micro sd card should I buy? (minimum) I was hoping to get a 64gb but if that would underperform, there would not be much of a sense to it.
The maximum reading/writing I will be doing in the note is probably playing 1080p playback + mirroring it to the tv. maybe some hi definition video recording as well straight to the memory card.. but most often than not, I would play a 720p mkv movie.
Would a class 4 suffice? Any suggestions on which brands I should look at / stay away from?
Class 4 of any decent brand should suffice.
Class 2 cards from Sandisk will also suffice (their read/write speeds are enough for 1080p encoding and decoding). May be a hassle if you regularly transfer a lot of data to and from the card since thats the time when the slower R/W speeds will come into play.
Why get anything less than class 10? If you can afford a Note, you should be able to spare another $20 for a fast sdcard...
class 10 cards can cost upwards of $80 for an 8gig card.

i picked up my class 10 a-ram 32gb microsd for $49.95AU + shipping.
it really depends on what you plan to use your note for. if youre filming 1080p video at the default 17mbps, thats about 2mb/s that you'd want minimum for just filming. so any speed should be fine as long as its above class 2. i just prefer faster cards since theyre getting cheaper.

I've read class 10 doesn't always mean fastest read speed or something to that effect. Not always beneficial to get a class 10 since it writes faster but doesn't always means it reads faster. Someone else can probably elaborate for me.

A-RAM is the brand. i bench'd it. write speeds are 11mb/s, read speeds are 14mb/s.
it was one of the random daily specials they had at www.shoppingsquare.com.au a week or so ago.
right now, the next best deal they have is http://www.shoppingsquare.com.au/p_276323_Kingston_32GB_Class_10_Micro_SDHC_Memory_Card

normally read speeds of class 10 are still higher than write speeds. but the read speeds dont really vary much between classes. my kingston class 10 reads at 12mb/s, my a-ram class 10 reads at 14mb/s, my sandisk class 2 reads at 10mb/s. so if all you need is read speed, then any card will do.
even class 2 or 4 on Sandisk it will work fine. i believe just buy a good make one ( not a fake from China ) , but i bought mine Lexar class 10 and work great , i couldnt be happier.

It doesn't necessarily write faster either!
All the class indicates is the minimum sustained write speed under optimal (i.e. unfragmented) conditions. It says nothing about the read speed, which is what is generally important in mobile devices since they are usually used for content consumption rather than creation.
As NZtechfreak has already mentioned, Sandisk Class 2 cards almost always well exceed the class minimums - I've been using 16gb Sandisk Class 2 cards in my phones for a long time now, and I've yet to get one that had a write speed less than the Class 6 minimum of 6MB/s, and the read speed has always been 20MB/s or above.

A good read why Class 4 cards are the best ones to use for your smartphone: http://forum.xda-developers.com/showpost.php?p=14456360&postcount=42
I started out with a Kingston Class 2 32GB I had laying around, and then switched to a Class 10 32GB made by PNY that I got from Microcenter for $59.95.
There was a very noticeable difference in photo taking lag and the media scanner, plus app access on the card. Now there is almost no photo lag, from snap to saving. Haven't messed with the video much yet...
I've Samsung class 10 32 gb. It's really good, but my device started rebooting because of it. "System Process has stopped working."
What I found out is that after removing my micro sd my device is a hell FASTER than before!!!
Maybe a faulty micro sd, no since it works fine in my pc and other devices.
I want to check does any of you have the same problem???

I know that there's been several threads about memory for HD2 before, however I just noticed that Kingston has made some 16 GB Class 10 cards.
That means that the read speed is 10 mb/s which is pretty darn fast compared to most Class 2 cards, reading only 2 mb/s.
But ofcourse, these cards is a lot more expensive (about 60%) so my question is if it is worth paying extra for that speed? Will the HD2 even be able to read that fast from the card?
Here's a link to a retailer, its danish sorry, but you should be able to figure out what it says.
http://www.getmore.dk/detalje-side.aspx?ProductGuid=SDC10/16GB-2ADP
well i got myself a 16gb class 10 card (Kingston) and am very happy with it.
i did a small test with a couple of high quality movies on all my 3 16gb cards (classes 2/4/10) and on the class 2 i get small freezes in playback, on the class 4 virtually no freezes and with the class 10 absolutely no freeze at all
this testing was done by myself and i am pleased with the class 10 card (and secretly wish i had one with 32gigs)
PS: All cards had the exact same data on them
can the HD2 even reach class 10 speeds?

i dont think it exeeds class 6, however i dont have a class 6 card around
there is however a difference between classes 2, 4 against class 10
the reason of me getting a class 10 was simple, they didnt have the class 6 i ordered left and couldnt resupply so i got the opportunity to get this one at a reduced price instead, which i of course accepted
big files are best copied over via usb adapter/card reader anyway (as it goes much faster) and there you will love the class 10 by lengths
Good choice, atleast you can look at replacing the phone in the future and still have a fast enough card or use the card in something else if you need the speed. was the class 10 expensive?

depends, for swiss standards the full price is a fairly reasonable 129.00 swiss francs which would be approx 80€ or so. I did however get it a bit cheaper than that
I reckon there are some tests involved by tokolosh, and that must mean something
But if I had to talk with my own experience... I'd say class 10 microsd's are useless to say the least.
My test was simple:
1) got a class 2 sandisk 16gb off singapore or something for ~30euro
2) put inside an SD adapter and tested with my linux laptop, got 7M/s writes and little less reads
3) put inside the HD2, and under Seven I get little more than 3M/s writes when connected in disk mode via USB, and surprisingly more than 7M/s reads
4) never had any lags of sorts during video playback, and I usually watch tv series on my phone, which have higher bitrate than movies (~170MB for ~20 mins).
So I'd say that as long as it's sandisk, anything class4 or higher is partially or totally useless

and this is where it would get interesting
Evening XDA!
So... It's time I upgraded my HD2's capacity. 16GB MicroSD's are now reasonably (ish! @ under £30) priced so that's what I want to go for. Most are Class 2 but I've seen a few Class 6s knocking about too.
Is the speed difference, in reality, a massive issue? Stuff I do that perhaps might require speed:
Watching XviDs in TCPMP
Taking photos
TomTom/iGO
Music
Will I notice much of a difference between the two classes of cards?
Any feedback is much appreciated! Thanks!
u just can compare my
kingston sdhc 8gb class 6
to
sandisk sdhc 16gb class 2
i could figure out a speed advantage of the class 6 about 0.8 mb per sec
my 16gb class 2 got 3.8Mb/sec
my 8 gb class 6 got 4.5Mb/sec
copiing the same file....
if somebody got different rates pls post them there.
i never had any problem with the lower data transfer rate of my 16gb sdhc, smooth vids, instant starting apps, nearly same "short" install time for apps
Ps.: i was copiing a 7xx Mb video file to my HD2 in HDD mode
I have a class 2 16gb in my HD2 - I've had no problems with the speed.
watching AVI files with coreplayer is always smooth, tomtom loads up in about 3-4 seconds.
Remember the read speed is a lot higher than the write speed.
Generally you are going to be OK with a lower class. There are however certain things that a lower class memory card will limit, like HD video playback or a high speed game installed on the card (I think Asphalt is a good example of this).
You have to decide what your going to be using the card for and adjust how much you are expecting to spend accordingly.
Be aware that if you are going for a reputable brand then buy from a reputable site. Buying a Kingston or Sandisk from Ebay for a knock down price may mean you getting a cheap knock off. Tread carefully, and give this article a good read, give you a better idea of how easy it is to buy a knock-off card.

Hope this helps
I have been wondering the same because I have been debating on buying the new Kingston Class 10 16GB MicroSDHC card but if the HD2 can't fully utilize the speed, I will probably splurge for the SanDisk 32GB MicroSDHC card and get rid of a few of my 16GB MicroSDHC cards. It is kinda a hassle to carry around a card full of movies, card full of music, and a card full of pictures so I would love to get a 32GB when the price comes down a little more.
Anyone know any reputable sites??? I'm in Australia... So hard to find one to ship Australia and cheap!
I'm after the Kingston 16GB Class 10 card!!!
Thanks a lot for the tip guys. I'll definitely have to have a think about whether I'll need the extra speed, of the top off my head I don't think so but there's a good chance I'll be slapping a few PSX ISO's on the SD card in the future which I guess might be a factor!
@above - unsure of Aus sites, but stay away from ebay as another poster said. 99% of stuff from China (and a lot of the stuff local too) is cheap, low capacity memory hacked to appear to be 16GB and often enough they even include viruses on the damn things too!
UK buyers - Play.com are doing Class2 16GB's for £28 delivered (+Quidco cashback, www.quidco.com)

the only place in oz i could find a 16gb card for my hd2 was vodafone. it wasn't cheap ($89aud) but i've not had any issues with it. it says it's a class 2. i'm sure i read here on the forum that the class really isn't an issue with the hd2 anyway.

Umart sell the Kingston 16GB Class 2 Micro SD for $55. Unfortunately it's the only one they sell (no class 6 available on the website). Have purchased several times from them with no issues.
I did not even know there was a difference in classes. Glad I read this thread.
Class 10 SD cards
Anything over class 2 (which means it can read at a minimum or 2Mb sec) will be a waste of money on a mobile phone. Class 4 and up to the latest class 10, are designed for the speed needed on high end digital cameras that shoot HD videos.
Save your money, buy a good quality, genuine class 2 card, you will not see any difference on an HD2 with a class 10 card in it.
Some users reported that after changing their bundled class 2 card with class 6, music, album etc are up to 3 times faster in loading.
I just ordered a class 6 card to change it with mine class 2, will report about it.
Class
Im using the 16 gb kingston class 2 and it works like a sharm... if you are really picky you can go with a higher class card but be prepared to add some extra cash for a tiny bit of quicker preformance
Just so you will understand how the cards are built there is not much diference amongst the classes. This cards all have 16 Gb space whitch cover the tiny sd card. the diference is that on the higher class cards, the bytes will be shared out in a much more constructive way so it makes it easyer for the phone to read the data. we talk up to 2 seconds faster from the lowest class card to the highest class card. I belive thats from class 2 to class 6.
Good luck with your choice
I will be receiving my g2x on around the 18th and need some advice on which sd card to purchase. Also which class is most recommended. All help and info is greatly appreciated.
you're a "senior member" and don't know what class sdcard to buy? ugh
Crazythunder, flaming someone doesn't help.
SanDisk is a great brand, and class 4 is high enough.
In my opinion the prices of class 6+ are too high for the extra transfer rate they give you.
I would go with a SanDisk class 4

Thanks so much for your kind reply. I was leaning toward a class 4 just wanted to know what others might be running in this new phone. Thanks again and I hit the thanks button.
placebo? Here's my story:
I was quite happy with my desire phone and wanted to use it as my main music player for the road (silly me).
To save me the time i bought a class 6 8GB card, while the desire was preloaded with a class 4 8 GB card.
Transfered all the music and was happy with the extra speed untill i noticed i made a small mistake, i switched those cards way to often and ended up with the class 4 card while i tought it was the class 6 one.
For that one time you transfer a lot of data it's worth it, but for everyday use .. not so much (and yes i used both cards as ext2sd cards, that was what triggered me, i lost a few apps )
In terms of the o2x; well we got a nice big space internal for our apps (perhaps we can use fdisk to make it even bigger?) and no control over the speed, so the external sd is purely for userdata; your phone won't mind a class 2, 4 or 8 it's just how patient you can be

This is a review (not mine) from Newegg...
Pros: Large capacity, great price and fantastic speeds. Class 4 card with sustained class 10 transfer rates. Blew the SanDisk 16GB Class 4 card out of the water. My previous 8GB PNY has lasted 8+ months with quite a bit of transferring. Let's hope this one lasts as well.
Cons: NONE.

ok, i blew it. i've been a wiseass all my life. but online in forums i usually always bite my tongue. for some reason i didn't tonight. sorry about that. won't happen again. my punishment is i got to watch the sabres have their asses handed to them by philly tonight.
I'll be getting the g2x next week since ive been waiting for an upgrade for a while i have a bunch of best buy gift cards. Im sad to see that best buy isn't carrying the phone yet and I am impatient so I currently have 175$ in gift cards I will probably use on accessories like an sd card, a mini hdmi cord(since it doesn't come with the g2x) and a thin case. I was looking at a couple class 10 16gb or 32gb cards because I wanted to run full ubuntu 10.10 through vnc on my new g2x as well as movies, music, games, and I will be using this phone to develop a couple games on in the near future. My suggestion would be to get a nice fast class 4(they do have them where they are faster than class 6 of different brands) if you are just going to do music and movies. Another thing to note is a lot of large sized games use the sd card to save data on. If you were planning on playing high end games you want those games to fetch the data as quickly as possible so I believe the faster the card, the faster the loading. Personally, I'm going with a class 10 16gb or 32gb with great reviews in hoping it will last me for a couple phones into the future

Hey guys,
I'm interested in getting a 32gb card. I will be watching movies off it and just basically reading books. Is there a huge diff between the two? I googled and I found the diff write and read speeds but my question is how relevant is it to the user? Like will the movies be choppier or books open slower? etc

Sadly, to throw a wrench in your question, there is authority behind the class markings. Basically, there is nothing stoping makers for marking a card Class 10, even when it can barely do 1MB/s writes. So, how does that answer your question?
It comes down to brand. Sandisk by far makes the best microSD cards, which almost always outperform their rating. I have an 8Gb Class 2, that constantly benches at 5MB/s sustained write, and 12MB/s sustained read. I also have an 8GB Kingston clas4, that can barely hold 2MB/s write, if it is lucky. The other issue few talk about is random reads, where again, the Sandisk is much faster (and random reads are not part of the class specifications)..
So, if you get a decent brand (again, Sandisk), a class 2 should be suitable for all music, and most movies. If you can afford it, class 4 will give you wiggle room.
How about adata? Have you had any experience with them?

personal experience no, but i haven't heard alot bad (actually, better than Kingston in many cases). I know they have decent prices on their cards.
With what i was saying before, it is fair to mention that while slow, my Kingston does still work. But saving things to it was painful, and so i avoid its use. Even if you don't get the fastest card, i think the biggest pain will be filling it once.. after that, using it should be ok..
I see. What about the performance? Saving stuff to it isnt much of an issue to me I think. Im more concerned on the performance. Like running movies off it and launching programs etc the sandisk sounds awesome but the price is much higher
For the use you are planning(movies) the big factor will be sequential read speeds. The class system is too easy for the manufacturers to game. Check the specs for the card you are looking at...if they don't tell you, it's likely because they suck. Sandisk class 2 cards are, as stated, usually better than the class 2 they are rated.
so you guys would recommend a class 2 32gb sandisk over a class 4 adata card of the same size yeah?
Can't really say one way or the other. From reading reviews at Newegg...seems like Adata tech support might be a bit iffy...then again those reviews are usually posted by those who have issues or feel like they have to defend their purchase(ie...fanboi's).
One thing I can see for myself...Adata is the only manufacturer on Newegg to actually list their full specs. Even on the manufacturers pages...only Adata has manned up and posted specs. otherwise they all just fall back on the SDHC specifications for class...which as stated can be gamed a bit.
At the end of it all..it's your cash...spend it the way you feel like...do some research for yourself first.
I have a scandisk class 4 32GB and it is way slower then a smaller class 6 that I have. For me, I don't think I could stomach anything slower then the class 4 for large files.

Sandisk is great. I was originally running Nookie Froyo from a class 2 Sandisk. It was actually pretty solid. I moved up to a Transcend class 6 and it's been good too. Both seem to perform well over their class specification when I'm transferring files and have been very stable.
On the other hand, my friend has a Kingston class 10 which seems pretty buggy. A lot of force close errors, looping boots, etc. Though these could just be a coincidence. Haven't seen him transfer any files though, so I can't judge the speed.
SD Cards..
You should be aware that Sandisk, Adata and others do not actually manufacture flash memory chips, they mostly package and test it - the big boys in the game are Intel, Samsung, Toshiba and Hynix. Depending on where or from whom Sandisk buys the basic chip the specs may be different.

Sadly, to throw a wrench in your question, there is authority behind the class markings. Basically, there is nothing stoping makers for marking a card Class 10, even when it can barely do 1MB/s writes. So, how does that answer your question?

Actually there is a requirement if you're in the SD Association. But in reality anyone can stamp a C10 on a card, especially no-name brands.

so you guys would recommend a class 2 32gb sandisk over a class 4 adata card of the same size yeah?

Absolutely. AData are junk in my experience.
Kingston and SanDisc are the only ones that are reliable for all devices that I've owned. Others are hit and miss, PARTICULARLY Patriot. I've had 3 Patriot cards that were JUNK in most devices. I had two Patriot SD cards for a camera that were fine but couldn't work right in anything else, and I (stupidly) purchased an 8G uSD card a few years ago for a phone and it was junk there, and I've periodically tried it in new devices for giggles and it's been junk in every single one.
I'll bet a SanDisc C4 out classes any other brand C10 in device like a phone or tablet.
Side note: All 3 Patriot's work just fine on my computer. I did tests particuarlly on the 8G uSD over and over and over and it was fast and reliable in my card reader. Every device locks up or goes slow as hell if it's in 'em. My guess is that they didn't follow specs closely.
So a Sandisk Class 4, 8GB would be a good pick?

I recently bought this on and have found it to be an excellent performer. Loading/watching mp4 movies. The 30 day return window is pretty generous.

SD cards are a complicated topic... not to throw another wrench into the system but you also want to be careful WHERE you buy your card. SanDisk counterfeiting is RAMPANT since a vendor can take a blank card, less than a pennies worth of ink and then charge you some percentage of the SanDisk price while still reaping a huge profit. As unfortunate as it is, real SanDisk cards always seem to just work while the other cheaper cards can be hit or miss. Honestly though the only real problem with off brand cards and the NC I have had is that they don't always boot so good. So I use my SanDisk 8GB C2 (bought from Costco) to boot and my Patriot 16GB C10 to watch movies and store stuff. Buying from Retail, Newegg, or Amazon (Amazon itself, not a sold through vendor on Amazon) should help make sure whatever you buy is the real thing. Good Luck!
Hi,
Does anyone know if going "too high" with a card on the G1 would be a waste ?
I currently have a class 2 samsung which does 5.6Mb/s write and 14Mb/s read - and loading the drawer (takes ages .. as sometimes also the desktop, even I did "keep in memory")
Would it be beneficial to go for a Class 10 ?
As the rom on the g1 is so small, like everyone else, I need to keep 99% of stuff and apps on the SD - so I think the performance issues are purely related to the SD
Thanks.
Nick
Class 2 is pretty slow. I bought a class 4 card and I am beginning to regret it really. I could have got a class 10 for just a bit more, but it was out of stock.
I would take a look at prices for class 10 cards, personally. I haven't owned a G1 very long but as I understand it, it's worth going for a faster card as you will be storing more on there than you would be with a more recent Android phone.
Thanks !
Will go for Class 6 or 10 depending on price. Still it seems my class 2 performs as a class 6 (nearly) .. and that some low cost Class 10 are closer to Class 6 !

That could be true, but if I remember correctly the class refers to the minimum sustained transfer speed, so in other words your class 2 should never drop below 2MB/s, and a class 10 should never drop below 10MB/s, etc.
When doing transfers to and from my class 4 I often see around 8MB/s.
At least that's how I understand it, correct me if I'm wrong anyone.
Yep - that's the definition it seems.
So back to the original question, it seems that it's always worth having a better class of SD, and there are no particular limits on the device side relating to the speed it can transfer at.

Basically, yeah.
I think it's more important with a slower device such as the G1 though - if you have a Samsung Galaxy SII with a 1.2GHz dual core processor and 1GB of RAM, well, you're not exactly going to need a swap partition!
And also it comes in handy having a faster card when installing apps to it, as the G1 has very limited internal storage as well.
got that.
Yes .. the limited user-space on the G1 is so painful.
