16GB MicroSD - how much will the Class affect performance?

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

Sandisk 32gb micro SD. Anyone tried it yet?

http://www.sandisk.com/products/mobile-memory-products/sandisk-microsdhc
I'm thinking about getting one, but don't want to drop 200 bucks on it without hearing what others who have gotten one have to say.

What class is it? I just tried finding that information out but couldn't find the specs on it. It it's a class 6 then I would be very tempted to get this. If it's only a class 2 then I will pass.

Am I blind or what lol! Yes, far to expensive for a class 2, and after owning a class 6 card I will never go with anything less.

There AERE NO class 6, 32GB or 16 GB micro SD cards on the market today. (I think its only up to 8GB)

Something has been bothering me for a while now though about a 32 GB class 6. I dont know if we will see one (at least at a "reasonable" price ANY time soon). Think about it. 32 GB is the absolute max the microsd can handle. Device manufacturers are looking into new storage options which should be implemented next year. I just don't know how big of a demand or even incentive there is to release an upgrade to a dying storage medium.

I'm really just looking for more storage space on my phone so that I can put all of my mp3's and vids on there without filling up my card. Class 6 would be nice. Honestly I've never even seen a class 6 micro sd card.

It makes a huge difference when you're transferring files to and from your PC if you have the class 6, much faster file transfer.

Yeah thats why I said I THINK! honestly I been with my 16GB class 2 for a really long time now and did some research on the technology of the 32GB micro SD card, I read somewhere that its not possible for the moment (or something like that when I read it) how ever IF THERE IS A 32GB class 6 or EVEN a class 4 I will Definitely BUY IT!

Samsung 32GB Micro SD
If I am not mistaken, I saw a Samsung 32 GB class 6 online for about $600.00. And I too have read that 32GB is the upper limit for microSD.

I have been using a SanDisk 32GB card for about 1 month now. It says "Class 4" but the transfer rate using WMDC seems a bit slower than it should be (when moving large files). I have since moved files using standard MicroSD reader and have no problem. The [email protected] can handle 32GB. Card is still a bit pricey (you can get 2 x 16 for a lot less).

I have heard RiDATA Lightning Series 16GB is freakin fast it is class 6 for 50 bucks looks like a really good deal.

i just bought one from ebay for $34.99 the seller has 100% feedback and people that bought them says they are good. so ill see if the knockoff works lol. its covered on the ebay buyer protection

Thats not true; sdcard.org/developers/tech/sdxc
2TB is the new limit

where did you guys get the 6 class? price?

If I have to spend $600 on a 32gb class 6 microsd, I'll buy myself an iphone 4 instead.

Sorry Bud, but that's SD-XC, not HC.
It's new tech, doesn't count. :3

First, 2TB is the limit for Micro SDHX I belive, and I don't think any PDAs or phones are set up to use them yet, next generation.
I recently got a Class 2 Sandisk SDHC 32gb at Verizon for $100. It was supposed to be $150 if you didn't have one of their phones (Droid X I belive) but they didn't ask any questions and gave it to me for the cheaper price. Works fine, plenty fast for video etc.
One note, I did try to buy a cheap '32gb SDHC' off thEbay and what I got looked just like the one I got from Verizon but was marked with Class 4. It would format with 32gb but when I tried to load data onto it after about 8-16gb or so it started getting errors. I figure it was one that was tinkered with internally to make it look like 32gb but actually was just a 8gb or 16gb in reality. I got suckered for $25 so beware.
Marc

I ended up picking up a 16gb class 4 Kingston one for 40 bucks that actually works really well and my phone doesn't lag anymore accessing files on my SD card like Music...

MicroSDHC 32GB C2 or 16GB C10?

I was thinking about upgrading from my current Sandisk 16GB c2. As many of you know Sandisk is out with there 32GB c2 MicroSDHC which is selling for $100 by Verizon. But if you look on ebay you can also find other 32gb c2/c4 MicroSDHC from TopRAM and Centon. Now I personally have never heard any of these company so I am very spectacle.
Now my question is which would you go with 32GB c2 or 16GB class c6/c10? To me its storage vs transfer rate.
1) Sandisk 32GB MicroSDHC Class 2 = $100
2) Kingston 16GB MicroSDHC Class 10 = $135

Clearly you should really been far 16GB storage even as decided to use even go want to do look more like 32GB transfer rate?

FYI 16gb class 10 Kingston is $98.99 over @ newegg and if you look hard enough u can find it around $79

I am not sure what you are saying but some claims that the Sandisk 32GB C2 they get around 5mb/s write. So IDK ATM as Kingston 32GB Class 6 is selling for $700 on ebay WTF? Last time I check they didn't even have 32GB class 2, could be fake who knows.

I am aware of that as they been had it for sometimes now but I was more leading to 32GB but who knows if I do decide to go with 16GB I might go with C10 from Kingston.
But has anyone tried TopRAM 32GB Class 4 or Centon 32GB Class 4? If so is it thoughly tested via R/W IOPs and fully chunking the card.

You cant go wrong with ScanDisk
its a safe bet

ilordvader could you test the R/W speed of your card and post back.

So after searching and reading many threads in various forums I came to the conclusion that even class 6 is an overkill so class 10 is out of the question other than bragging rights.
Now has anyone used Transcend or A-Data? they seem to be selling at Newegg so they can't be questionable unknown like TopRAM or Centon which I never even heard of until I was searching for MicroSDHC.
Anyone recommend any 16GB class 6 cards? I am still unsure on not ordering SanDisk 32GB Class 2 as storage is high but the speed is low. As majority of user who running Android port do recommend getting anything over class 2.

Extreme candidates:
Sandisk 32GB MicroSDHC Class 2 - $100 < Storage
Kingston 16GB MicroSDHC Class 10 - $135 < Speed
Are these the only reputable 16GB Class 6 candidates?
A-Data 16GB Class 6 - $53.99
Transcend 16GB Class 6 - $62.99
Lexar 16GB Class 6 - $69.99 < Questionable; produce inferior products
Has anyone heard of these company before?
Centon 16GB Class 6 - $58.99 < Questionable; but listed under Newegg
3C_Pro 16GB Class 6 - $44.99
TOPRAM 16GB Class 6 - $44.99
Team 16GB Class 6 - $44.99

i bought this. Komputerbay 32GB MicroSD SDHC Microsdhc Class 6. £88, which was preety steep.
i get read speads of around 3.5 mb/s and write speeds of 4.5 mb/s, i cant find my 2 speed to compare but it does seem quicker.
though the web site gaurantees minimum 6 mb/s write speeds.
it was amazon so i though it would be ok.
edit.
just tested it again i am getting 6 mb/s read speeds now.

johnwalk did you thoroughly test the card? by formatting and filling it up fully with chunks? if you can confirm its overall performance then I might also order it. Can't wait for other vendors to make it as I need it now. On class 2 card it takes like 30min to just move around 4.5gb now that's way to long for me as I'm always on the go, but thanks for your reply as ill look in to that company.

I don't want to spoil anything, but my HD2 just destroyed my 8GB Sandisk card. 'Luckily' this was not a $100 card, but still.......
Are you shure you want to spent that much, or did you never have your previous card(s) being destroyed?
Wish you goodluck anyway

i just formated it normally the filled it up with music and video still got two gigs left im like a dog with two tails i dont know what to listen to first lol. but the tests i done with it was when it was 28 gigs full only had it two weeks and at first it was slow, especially when you went into the music player it took a few seconds to update but hey a lot of files to browse but its been ok the past few days, but im now at the stage where i dont plug it into my computer anyway i just access my pc and transfer albums by wifi takes about a minute an album, any video usually gets streamed anyway, but wanted a bigger selection when i go on holiday next month.
def recomend this card thougth the first few days i thought i should have gone for the class two, im now happy with it now it all working properly.

I'm at work now and in an hour when I go home ill thoroughly look in to this card and post my finding. As I never even have heard of the company and if I like it ill post feedback here so others can buy it with confidence.
Far as flr goes how did HD2 destroy your card? corrupted the data? or the flash device is unreadable fully? BTW I never needed an flash card before as this is my first smartphone. Also I was welling to spend $750 few months before HD2 was officially deployed in USA. So I'm not worried about $100.
PS: Also have an eye on HD3 as the spec is 90% accurate from my guess after looking at the specs. So let's see what happens as I don't want a device which may have 2 versions, hence EU-Leo512 and EU-Leo1024.

off topic but im seriously looking into the new batch of android tablets which are just coming out now, maybe 7" or 10"

Hope the HD3 is for Att this time

I've got up to 14.7 MB/sec on my 16GB Kingston Class 10.. and my phone works soo smooth now!
Compared android sliding of homepage on my 2GB Class 2 card and my 16GB Class 10 card, and there is some lag with the 2GB card, and none at all (100% realtime) with the 16GB card..
So, personally I'd say; save some exrtra bucks and go for the 16GB Class 10 Kingston one!

@HyperNode
There are several threads here regarding SD cards being destroyed, or whatever description is given to it.
From one moment to another you get the message that you're card has to be formatted. If you accept it, it says something like (only) 30 MB being available, which doesn't get formatted. Your card can no longer be seen by your HD2, nor by your PC or any other cardreader (afaik)
I´ve never had this problem before. It looks like a specific HD2 problem.
Either with or without a combination to a specific brand or card.
I'm very curious about your experiences.
Please keep us updated.
Thanks and goodluck!

Same here. Mythen hd 2 just destroyed my SD card des SYstem ago
It happened already bevor, Thatcher i couldn't See Thema data anymore , but nie i Cantel even Format it anymore

Which SD Card to get?

I am inbetween these two cards. One is a Kingston 16GB Kingston class 4, while the other is a 32GB Sandisk class 2. The only thing I'm concerned about is the speeds on the 32GB Sandisk SD Card, how do you think it will compare with the Kingston?

Real world performance... most won't notice any difference in speed. Go with the 32 GB, as the extra storage can be extremely handy.

I use the 32gb with an Incredible, speed is fine.

I compared 3 cards. Sandisk 16GB class 2, Transcend 16GB class 6, Sandisk 16GB class 4.
The Sandisk 16GB class 2 actually out performed the other 2 cards in write speed. The Sandisk class 4 had a slightly higher read speed than the class two but just not enough to justify the price difference, so I went with the Sandisk class 2 cause it's an all round performer and it's cheaper than the other 2.
I got mine for $27.00 locally

I got the 32g from Verizon. It's a class two, but all the Sd Card "Benchmark Apps" rate it as a class 4 for what its worth. Definitely the 32g...Way handy!

Thanks for all the responses guys. I guess I'll definitely be going with the 32 GB one then!!

Look on new egg you can get 32 gb for about 70$$ there, it's where I got mine
Sent from my HTC Incredible

I got the Kingston 32 gb Class 2 on ebay for $49 free shipping. You may want to look there.

Get one of these two Microsd cards if possible
I have found this card at newegg class 10. 16gb, even got a review for the htc incredible that was not bad, but the person did say that it only read it as a class 6. Was only $28. its sold out as of right now, but when it comes back you should probably get one. Im hoping this company makes a 32gb version.
but if you want a known name brand then I would go with Patriot 16gb class 10 microsd which happens to be also out of stock but goes for $38. Probably just the price difference on name brand, but you never know. both are unfortunately sold out. means they are hot right now.

Cheap class 4 8gb sd and 16gb class 6.

http://www.ebay.co.uk/itm/251038684911?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I bought the 8gb for £2.80 yesterday price seems to have risen most likely because people were buying a LOAD of them.
http://www.ebay.co.uk/itm/MicroSD-T...S_Accessories_Software_ET&hash=item3cc384c620
Probably the cheapest prices i have seen.

I would never buy anything like a class 10 card from eBay unless the seller was someone like eBuyer or Argos, so many fake cards on eBay.
Better to pay more and know you are getting class 10. Also the class doesn't mean a hole lot, read and write speeds are what you should look at.

The class of the sd card IS what indicates the read and write speed, a class 10 gives you min 10mb sec write speed.

It's also good to pay attention to the manufacturer. Some no-name class 4 card I got was barely working, while there's no problem with a Kingston one, with the same specs.

Iv been using a genric class 4gb sd card for years and i still get 5mb/s write speed on it.

My class 4 barely manages 4MB/s, usually in the 3s. Sandisk
Sent from my Optimus 2X using Tapatalk

I got the 8gb sd card in the post, speed test shows at 4.8mb/s write speed.

It happened to me to find micro sd cards not respecting class written on them. there are a lot of softwares that mesure writing and reading speed. Personally, I would spend a little more money for a good product i.e. I have a 32Gb Samsung, Class 10 and I payed it 35€ (shipping included..)
If you don't need a big capability, a good 8gb or 16gb can cost you not more than 10-15€...
It's something you buy once and least for year..buy it good and you won't regret it!
