Default Best 32Gb Micro SD card for SGS2?

Just wondering if anyone is using a 32Gb Micro SD card in their SGS2, and if so what make [brand] is it and what are your thoughts on its performance?

Lol, i know NZtechfreak will probably say all you need is a class 2, sandisk. But personally, any major brand should do, either class 2 or 4 maybe class 6 if you want to future proof your purchase, however you will only really see performance benifits if the card itself gets plugged into a laptop for file transfer via sdhc adapter.

I guess check out Kingston or Crucial as well as Sandisk, maybe samsung.

I have a Class 2 Sandisk card - although its Class 2 its fast enough for encoding and decoding 1080p, which is all you need. I always recommend Sandisk, although other manufacturers are decent too. The mymemory branded one is OK, I got one of those for my partners phone and she's had no worries.

Here is another forum with some posts about cards, and the benchmarks of my Sandisk and Mymemory cards -

Micro SD cards
Thank you, that is very helpful.

I checked out the 32GB SanDisk and the cheapest I found was 62.49 at Play.com, it was much more expensive at myMemory.

Play.com's info provides the following:

Capacity: 32GB
High storage capacity for storing essential digital content such as high quality photos, videos, music and more
Optimal speed and performance for microSDHC compatible devices
Speed performance rating: Class 4 (based on SD 2.00 Specification)
High Quality microSDHC card backed by 5 year limited warranty
Built to last, with an operating shock rating of 2,000Gs, equivalent to a ten-foot drop
Easily transfer files between your digital devices and computer
Hi-Speed USB 2.0 compatible transfer rates.
View, edit, and copy photos/data/music.

When are you going to benchmark the major brands with the same capacity/class cards? That would be interesting

Thanks for this. I have used other cards before on different devices, but when it comes to the processing speed of the SGS2 I was hoping to make sure I didn't fork out X amount of readies for something not able to deal with it.

This may be a silly question, but are microSDHC cards compatible with SGS2? As I'm mostly finding microSDHC cards for sale, but Samsung lists the phone as having only a microSD slot.

Yes, it's a bit of an oversight.

Any sd card 4gb + will most likely be sdhc, as I believe the earlyer sd standard only supports up to 2gb.

So although it's only started that it's a micro sd slot, it should be technically corrected to the "micro sdhc slot" term

class 2 is too slow, oh sure it's fine for in the phone, but try to copy a big chunk of files to it and you will see it takes a great deal of time. Class 10 is super fast but kinda costly at the 32gb range, I would go class 4 or class 6 is even better.

Default Sd cards

Just looking at some 32gb cards for the GS2 and have come across one for 45 sterling's made by Dane-Elec. It says that it is not *backwards* (WTF) compatible and to make sure the device is SDHC enabled and will accept the card, before buying. Does any one know that it is in fact SDHC enbabled. Also is this a good make?

If by "it" you mean the SGS2 then yes. I has to be because there is no such thing as a 32GB SD card that is not SDHC. Consequently, any device that accepts a 32GB card of any sort must be compatible with SDHC.

SD cards work in SDHC slots. SDHC card do not necessarily work in SD slots.

As said in other posts, I believe the SD standard goes upto 2gb where as the SDHC standard ranges from 4gb - 32gb cards.

from what i read stick with either sandisk or lexar branded 32gb micro-sdhc cards class 10 if you can find them

They're still expensive in Australia so probably get one from adorama.com who ship to Australia. Currently using 16GB Sandisk micro-sdhc.

I got a Kingston 32gb Class 4 for 50 from ebuyer, it's plenty fast and a good reliable brand to boot (i've had Sandisk cards just die on me for no reason in the past).

I'm just waiting for the 64/128gb versions to be released as 32 has never been enough for my favorite music collection

The SDHC standard only goes up to 32GB. The next version, SDXC goes way higher (more than 2TB I think) and these are available now in the SD card rather than micro SD form factor.

What I don't know is whether these will work in our phone. I suspect they may not but does anyone know for sure?

[Edit]

According to this thread on Engadget http://www.engadget.com/2011/05/26/kingmax-flaunts-worlds-first-64gb-microsd-card/ there are already 64GB SDXC cards and the hardware is basically the same. The discussion on the comments on that page suggests that there will be no hardware incompatibility. I'm not risking >100 of my money to find out though. Any brave (or rich or foolish) people out there willing to test one?

I started my collection in the 90's and over the years it's expanded to cover all the best music over the last 70 years (good music is timeless to the wise mind).

I would say i'd be content with 64gb of space for my music collection on the go but i would like another 16-32gb for videos on top of that also.

If there wasn't a size limit on mobile internet (i still don't see a good reason why it should be as unlimited broadband has been around for years) and media streaming wasn't such a drain on the battery, i wouldn't need to store my favorite media on the phone locally, i could just stream it instead.

Which is why the stupidly named 'Cloud' concept is going to be massive.

So two obstacles need to be over come before smart phones become completely useful to me.

A) mobile providers need to stop being greedy gits and start allowing customers unlimited mobile internet for reasonable prices (3 and Giff Gaff have just started to lead the way in this area)

and

B) new battery technology that provides at least triple the battery life we are currently getting needs to be introduced.

The SG2 has a 1650mAh battery which isn't the largest capacity on offer for a smart phone, that title goes to the Motorola Atrix 4G which has a 1950mAh charge and while that might sound impressive, we haven't actually advanced that far in the last 10 years.

The first mobile phone i ever had back in 2000 was the Nokia 3210 (those were the days) and even that had a battery life of 1250mAh.

So basically (in terms of capacity) over the last 10 years we have advanced a mind blowing 700mAh extra, woot!

Well i've been keeping a close eye on MicroSD technology and their press releases over the last couple of years now (i've been dying to get my hands on a 32gb card since 2006!) and while everything i've read leads me to conclude that the new SDXC cards will not be backwards compatible with the current technology.

Kingston comes along and releases a statement like this:

Quote:
The Kingmax 64GB microSD XC complies with SD3.0 and Class 6 specifications and is also backwards compatible with the SD2.0 specification, the company said. Kingmax estimates the microSD cards will be able to store around 15,500 MP3 files or around 155,000 JPEG images.

Kingmax raises microSD storage to 64GB | ZDNet UK

So there is hope after all

I can't image using a C2 card in this phone. The C2 8G in my Aino would not keep up with its recording on the 8MP cam it had. Maybe the video is better compressed on this one, we know it has the power to do it, or it could be buffing the video to the ram?? Any way I've decided to stick with the C10 16G card from that I using in the Aino to get smooth recording. If I update to 32G I would look to a quality C8-C10 again as I see no reason to have a fast phone having to wait longer than needed on the SD card.

On NZTechFreak's advice (for which I thank him), I went for a Class 4 card and it is easily fast enough. I know it always seems appealing to have the fastest whatever it is but I don't like wasting my money. My Class 4 and NZTechFreak's Class 2 both work fine. There is no point in buying a card that is faster than the phone can drive and my card can keep up with video capture or play so what would be the point of spending more money on a faster card?

The only advantage really is data transfer via a PC, if you think you'll be doing lots of that, then it may be worth it, if not, then stick with class 2-4.

I do lots of transfers to/from the PC. That is where most of my media is. Phones still can't match the capacity of a PC, drives in mine are just shy of having 5TB, so I'm often rotating media in and out of my phone to keep it "fresh".

Maybe if I get bored I can still that old C2 in there and do some pic timing test, the retest with the C10. I know that on the Aino there was a big difference in the time between taking a pic and being able to take the next. With a 2.5 year old you need a fast camera or you always miss something. Again though, this is my first venture into Android and I've not had the phone a week yet. Maybe Android uses the ram for caching better than the Aino, I don't know.

As I said, for those who transfer a lot of data, as you do, you will most likely see the benifit of a class 10 card. But some users don't transfer that much, and so can't justify the extra expense.

Going on nztechfreaks info, 1080p video recording to an sd card is about the hardest thing the sd card has to do 'in house' and for that, class 2 is sufficient, apparently.

So it remains, (it seems) that if you intend to combine your phone with a pc for media transfer in a regular basis, then you could well gain from investing in a higher class sd card.

Regarding to those who asked about SD vs SDHC, theyre the same thing. HC just stands for high capacity.

Lexar do a 32GB SDHC Class 10 for 45 if you search google which cant be a bad price for those looking

I have a 16GB class 4 Kingston. Loads up plenty fast but if you want rea speed, get a class 10...lol. They are well under a $100 now for the 32GB compared to last year this time.

Would anyone go for a higher class, lower branded card such as Komputerbay Class 6 or a Sandisk Class 4 for similar money?

That's not really true, they are different standards and SDHC cards will not necessarily work in an SD slot.

That Lexmark card looks good value but I searched high and low about a fortnight ago and absolutely everywhere was out of stock. Do you know anywhere that has them in stock?

Transfer speed.

I find class 2 (2MB per second) more than adequate for both video and music (but only if you use a dedicated card reader instead of the phone).

I do this for multi GB transfers (with my card reader i get 4MB speeds on a class 2 card and 6MB on a class 4).

I've never paid more than 50 for a 32gb Micro SD card and even then i consider that hugely over priced considering a decent make 16gb version is only 15 online.

So, from my above post, in general would users buy a higher class small brand or lower class card of a better known manufacturer. Komputerbay as opposed to Kingston?

I usually go by how long the warranties are and existing user reviews (i won't buy ANYTHING if there is no user reviews, far too risky).

32gb Micro SD cards are currently very expensive, you don't want to buy one that will only last / be covered for replacement for only a year now do you?

So if I understand correctly, if I buy a 32GB Kingston C4 and I record my 1080p video, I will not see any difference in quality as opposed to a C10. As well as running apps? And that I would only notice the difference if I transfer data to my PC?

I just purchased a Kingston Class 4 32GB SD Microcard for my SGS2 at US$38 from HK and it would only load 4GB. The E Bay supplier gave me my money back and was convinced card was not second but from China manufacturing plant that was reputable. Anyway I am now looking for another 32GB Class 6 SD card in another brand . Kingston is lost for for me. I have confirmed formatting on PC and within phone keeps formatting to 32Gb fine but will only load 4GB of music/videos etc

Got my 64GB Micro SDXC card today from Sandisk - not meant to be compatible with the SGSII but if you format it to Fat32 it seems to be working fine...

Ebay is full of fake memory cards, buy from a proper retailer instead.

I got my 32gb class 4 Kingston microSD card about 6 months ago from ebuyer.com for 50 quid and it's still going strong.

Can you update us on how things are going after you have filled up all 64gb?

Cheers

Sweet

140 is a bit rich for my blood personally, i think i'm going to wait for it to drop to 100 before i buy but i am still very much interested in its reliability and performance over the long term so please come along in a few months time and update us.

It would be much appreciated!

I will. Although it works for now there is always the question of whether it will corrupt itself or something in longer term use outside the manufacturers guidance.

San-disks limited warranties for MicroSD cards is usually 5 years.

Not sure if the warranty applies when I've changed the format of the card and using it in a device that isn't recommended!

Got my Sandisk 32GB class 4 yesterday (Amazon 33.49), put nearly 15GB of music, mostly flac, on it and it seems fine... reads around 18 MB/s and writes 4.5 - 5.

Won't be using the Sandisk Media Manager Coupon, drag and drop works just fine in non-debug mode.

Does the class number matter for apps or games? Say if I wanna play modern combat 3(not out yet on android but will be this month) it's a 1.7gb game once installed and that game is really heavy on the graphics for my iPhone, would that game be slowed down or any performance drop if it were to be on a class 2 or 4 card?

See this topic. A Class 4 card should be more than adequate if storage is the main use.

I brought a Kingston 32GB micro HDSD card for 25 yesterday....

Copied some files over to it and most of them wont play now. Infact they come up corrupt.

Ok. So I slipped in into the adapter, plugged it into the laptop, and i'm moving a huge amount of files to it and the transfer speed of 4MB/sec seems accurate...

I'll see what the files are like after transfer. If they check out ok then it must be the transfer on the Android system that corrupt the files.
I'm running H2testw and yea... it's bad. The test is at the verification stage and it states "The media is likely to be defective" and DATA LOST/CORRUPT is 7GB and increasing!!!!

Ah well, I've learnt my lesson here...
