Do i NEED a Class 6 Micro SDHC Card

Hello all,
Ive got a spare 16GB Micro SDHC card which i have swapped for the stock 2GB version that came with the Desire, but it is only a Class 2.
Having read that its best to use Class 6, should i shell out £50 for a new one, or will i not notice a difference in class ?

Dunno - I'm using a class 2 16gb card myself and I don't notice much slowdown if at all. I'm surprised these things haven't come down in price after two years... key thing is do you notice any slowdown with apps that access the SD card? like I say, I haven't thus far...

i read somwhere that class 4 is enough coz the phones do not support hihger speeds. class 6 will help you if you will take card to the card reader straight to the computer... it think

Thats what i ......... think. Im sure it only matters if its connected to the PC, and in that case i dont care.
I read it on another forum that i wont link too
Class 6 are almost double the price of Class 2.

You don't NEED to get one, I did use a Class 2 card for a few days and didn't have any problems.
Personally I am using a Class 6 now, as I regularly transfer a lot of big media files onto the card, so the extra speed is worth it for me.
If you don't fancy forking out though, you don't have to.

I totally agree, My desire came with a 4gb sandisk class memory card which I initially assumed was class 4 until I took the card out yesterday...connecting the desire to my pc and switching to usb drive mode, i am able to transfer my movies etc to the memory at +/- 8Meg per sec which is more than adequate enough for me...I was about to get a 16gb one but was thinking of getting the class 6 one until i discovered the one I currently have is class 2, so I just made up my mind and went for a class 2 16gb, saved me money....

They only refer to the write speed of the card, i came from a 8gb class 6 and now have a 16gb class 2 and notice no difference, only difference is the write speed from pc to card.
Even though i got a class 2 i still see 4-6mb/s so happy enough with that.

I have a class 10 16Gb card in phone. Read and write speeds seem to be limited to around 8Mb per second (copying uncompressed music). Using an adapter, the computer is able to copy at 14Mb+ using the same card.

They just seem a big outlay for nothing to me, lets face it the only big write time is when you transfer everything across from your previous card once the stuff is on there the write times really won't be much of a problem.

The main reason you will find people suggesting class 6 and above SD cards is due to "Apps to SD". For the Newbies "Apps to SD" or A2SD is a modification that has been done on most android phones (though not the desire at time of writing) which allows the Apps you download to be stored on the SD card rather than the phones limited internal memory. I am not sure if it makes a huge difference to the faster processor phones, but in the G1 days it was noticeable. For just moving music and pictures about it isn't really important to have a faster card and we may have to wait a while for A2SD anyway. I will pop over to the N1 forum and see if they can shed some light on this.

Anyone using a microSD 16GB Class 4, if so are they any good? I'm looking at buying one for the Desire. Also where's the best place to get a deal on one of these card?

16 Gb Micro Sd class 10

I wanted to let anyone looking for a micro sd about a deal i found. I found a Patriot Memory 16gb micro sdhc class 10 for $39.99 on www.CompUSA.com I think i'm going to order one after reading here on xda that patriot makes a pretty reliable sd card. I haven't ever used a patriot memory product so i only know what guys on here have posted. anyone make sure you check into the company on your own. They have the wintec 32 gb class 10 for $84.99 too!

apparently class10 cards are no good for phones, take a look at this link

yeah you dont want to spend all the money on something that might not work right?

I had read here on xda that the class of the sd card doesn't matter but the size(gb) is what matters with phones. like my SE X10 is only compatible with up to 16gb of external memory. Is that not correct? Can anyone clear this up for me?

X10's are compatible with up to 32gb microSD cards, I've got one in mine.
The size is important as you want to buy an SD card that works for the content that you intend on putting on it. If you have a lot of MP3s and videos, take a lot of pictures and shoot a lot of videos then obviously you are going to want at least a 16gb SD card.
The class does indeed matter. If you have hundreds or thousands of images then a class 2 card would take ages for them to all load in the Gallery. Or if you use App2SD at all a class 2 card wouldn't be able to keep up with the reading and writing and the app would be sluggish.
A class 10 card in my opinion is a bit excessive, I'd personally go for a class 4 or 6.

This is very true. I have a class 2 card and loading thumbnails for artists/albums is painfully slow in mediascape. I would go for a 32 GB if you are a music fan. I have a 1800 songs on my X10 and its already full. Class 4/6 should be good, class 10 is a little excessive.

Just take the card out of the phone. There should be a 'C' printed on the card and there will be a number inside the 'C'. This is the class of your card.

I was using stock 8 GB class 2, I brought Team 16 GB class 10. Difference in performance is noticeable.

I have a class 10 8gb card and it works way better than the stock card.
Just make sure you tweak your read_ahead_kb.. Search for SD card speed improvement or speed increase.

In general, Class 4 or 6 are good enough for the application usage by phone, such HD video and phones.
I tested my Class 4 sd card, it able to transfer ~5.5mb / sec, not bad.
Yes, when price come down, I will get a Class 100 sd card too.
cheers

I'd rather the class 200.

Class 10 significantly improves the performance.
Honestly it does not matter if someone is using the SE stock rom...however since I have tried the awesome ROM created by wolfbreak...my apps stored in sd was very sluggish...had to buy a class 10 16 gig to improve the performance...

Just got a 16Gig class 4 card...goto to play with data2sd and see the quadrant!!!!!!

If you get a real kingston class 10 you will get five times the speed of a low spec class 2 generic sd card.

Real Class 10 SD cards work at 10MB/s of data transfer speed.
Class 2=2MB/s
Class 4=4MB/s
Class 6=6MB/s
Class 8=8MB/s
Class 10=10MB/s
The best are as said by others Kingston and Sandisk.
I've a Sandisk class 6 card and i get near 5,5MB/s of data transfer.
Mine is still 8gb, i want to buy another but in Brazil it's very expensive, the taxes are very high.

Got the Wintec Filemate 16gb class 10 for just under $40 at Frys Electronics and it's given me no problems. Used it in my NookColor running tons of apps and music from it without a hitch. Now it's in my X10 and with using the SD Speed Up tools, it helped alot.

[Q] Anyone here use a Class 10 SD card for Android?

I'm looking to upgrade the crummy 1GB SD card in my wife's TP2 to something faster. I was wondering if buying a class 10 card was worth it or if I should just stick with a class 6 or lower. Does the SD slot in the TP2 even support a class 10 card? Would a class 10 card be noticeably faster than a class6?

Not for this project. IIRC Nate said class 4 seems to be the sweet spot, the higher the class the worse it would be running XDandroid, but even some class 4's work better than others. Walmart has 16G class 4 sandisks for around $20, not too bad if you ask me

C10 cards are supported, but some have had issues. I would not recommend a C10 card for Android use. I doubt the phone itself will be any faster...

Cool. Thanks. So get a class 4 then? Is it worth it to get a 16 over a 8GB? My wife doesn't put much on her phone really and she streams all of her music.

Yeah I've got a Patriot 16Gig Class10 SD card that I picked up on sale months ago. I have been running XDAndroid on it since then and haven't noticed any benefit over my old 4gig class 2 card.
Not sure if it's related to running andriod but at first I was having issues with the card corrupting and losing all data on it, having to format it to be usable again. Formatting a few times with the HP tool seems to be helping.
I had a similar issue with my last phone (HTC Hermes) which would only work with good quality (Sandisk) SD cars, and failed with cheap chinese flash memory. The issue was that the phone wasn't able to remount the card properly in winmo when coming out of sleep, and the filesystem would become corrupt pretty quickly with folders disappearing and files having wacky filenames. Sounded like it was more of a hardware issue than anything.

Yea I use a class 4 card. Some have reported oddness with class 6, so it seems like the type of card matters as well... Because others with C6 cards say they work just fine. I've even had some people say C10 cards are fine, but most seem to have issues with C10 cards. Don't get some cheap knockoff, get a name brand.
As for size, that's entirely up to you. You can have up to a 32gb card. 512mb minimum .

I have a Patriot 16GB C10 card here too, but I no longer use it. It was constantly getting corrupted, the kernel logs were filled with I/O error messages. I'm now on a Sandisk 32GB C4 card and no more problems.

Just don't get a C10 card... I think that's what people should take away from this.
Some have said C10 cards are fine, but most say they are not. A few have had issues with C6 cards, but most say those are OK. I've never heard of people complaining about C4 or below cards - hence the reason I recommend anything C4 or less.

c10 sd android
My company name is WinDroidz and all I do is mod android and windows devices... and I have always seen huge performance gains with c10 cards, c2 sucks major, its just the transfer speed the card can move data at and clearly more speed no matter how u look at it with an SD card. Is crucial... I always used patriot c10, or topram and pqi c6 cards for android SD on windows devices and have only seen a posative result.. this is based on my personal experience of Modding more Devices then I can remember.... not from what I read somewhere or was told by someone... SD card data transfer is the slowest method of data transfer of all other common used methods... there are graphs if u Google it that show sdhc c2 cards lined up against other transfer methods like USB, ide, sata etc..... to put in perspective how ridiculously slow SD cards really are, once u see that u will understand why your phones drags ass so much when trying to pull up gallery after cache has been wiped if you have a ton of pics etc.... so if u are having problems with a higher class SD its probly not the SD and is something else you are doing, or maybe the brand as I can only vouch for the ones I've used... (wouldn't care personally about brand as pretty much everything is same manufacturer with restamped brand and packaging.. Kingston is Japan... currently using a c4 Kingston 32gb in my desire HD (wish it was a c10 but kinda pricey for that size and brand) I recommend c10 8gb for $30 on Amazon if u are using some kind of android SD rom.. or any device if u want better transfer speeds and it is very noticeable... no matter what speed u get though it will never run like nand android.. like HD2. So lets just hope the nand development for other devices continues like clk or magldr did for hd2 cause the hd2 with clk and full rom manager support is amazing

16GB class 10
Using 16GB class 10 and have had no problems related to the card, with FRX07.
I personally cannot think of any logical reason why a class 10 card of good quality should ever be a problem.
I just installed and ran Angry Birds Rio. It is slow, but works. Kind of fun to play in slow-mo!

i use 8gb c6 and haven't had any problem so far.

My 16GB RiDATA Class 6 Micro SD has been great, no problems.

good 32gb memory card?

what do you guys think of this brand? decent? new time sd card purchaser...

Looks like garbage. Stick with trusted brands like SanDisk, Transcend, Kingston, PNY, etc..

I agree with Pheno.menon but the price might be worth the shot. Just make sure you use Paypal. I have tried a few of these even named brand and had the file with Paypal to get my $ back. You also want to test the speed if you get get one. I had one marked as a class 6 but wasn't even a class 2. Made the phone freeze up.

I remember reading about a delay when unlocking the screen whenever an SD card was installed. Can't seem to find anything about it now though. Anybody know what I'm talking about?

I get the slight delay but the thing with mine is i get the delay whether my sd card is in or not.

I remember back in the day on the G1 when you had to run apps to sd and partition your card. I bought a supposed class 6 8gb card on eBay for cheap. It was definitely slower than my Sandisk class 2. I'm using a 32gb class 4 SanDisk I conned my buddy out of his Thunderbolt. Must say so far I like it. Try craigslist. I know I picked up a 16gb for cheap a while ago...

higher class number means higher write speeds, but that doesn't always mean better read speeds.
IMO higher class cards are better when your doing photography and video stuff
I read my card more often than write to it so a lower class card with better read speeds is better for me.

I got a sandisk 32GB class 4. It is plenty fast enough. I record pics/video to onboard phone storage anyways. I store vids, music, etc on the sd card and it reads very fast. I haven't move any apps to sd card because we have plenty onboard memory.

what's a good price for a 32GB class 4 microSDHC? i've been waiting for about 2 weeks for a deal to be posted on SD, but haven't seen one yet.
amazon is selling a sandisk for $37. i'm wondering is i should just buy this?

Bestbuy has the Kingston class 4 32gb for 42.99? Do you all think that's a good deal? I know amazon has the Sandisk 32gb class 4 for 37, but i has mixed reviews.

What is the brand on the card? It may look good, at 32gb class 10, but if its not from a decent manufacturer it may not be worth the small price you paid.
Personally, I stick with pny or sandisk.

Thanks for the FYI on Pny.
I know they are a cheaper brand(price-wise) so I tended to avoid them for more name-brands.

is it a simple COPY > PASTE affair to upgrade to a new card?
i read in the past that other phones used the sd card for swap and such, which needed different procedures to upgrade but the Inc2 doesn't have any of that dependency
i picked up a 32GB Class 4 Sandisk card which should be arriving tomorrow. Hope the upgrade goes as smooth as yours
ps. you should do some benchmarks of your pny class 10 vs the OEM card. as i understand it, the sd controller in our phones aren't rated for class 10 speeds, which is why i didn't bite on the faster (more expensive) class 10 card. it would be interesting to see a comparison though.
you can use something like AnTuTu Benchmark or SD Tools. both available from the market.

This. a class 10 is kinda pointless for a phone. i remember reading somewhere on here about how any card above a class 6 will slow the phone down.
Also that off brand sd card was probably not a 32gb nor a class 10.
I bought something similar off ebay a while back and it ended up being a card that was labeled 32gb class 10 but the benchmark stated it was a 200mb class 2 or something like that. They take these already labeled 32gb class 10 cards which failed the test off the line and resell them as such although they are not.
glad you got your money back

i used AnTuTu Benchmark with the OEM 16gb class 4 card.
read: 4.4 MB/s
write: 16.6 MB/s
the Sandisk 32GB Class 4 card I picked up, according to the reviews, have above-standard write speeds for a Class 4 (something like 5-6MB/s). i'll post up scores when it gets in but i would suggest this one just for it's brand name and consistent reviews

Buy that card from Taobao?

hey guys. i have been trying to migrate over to the 32GB sandisk card without luck. the file transfers over just fine but my phone can't identify where the apps are (the card is recognized in the phone, including the full capacity).
i'm trying to resolve this before doing the benchmark. any help is appreciated!
Ps: i just copy>pasted from the old card to the new card. nothing fancy and no errors. and yes i do use App2SD

Did you unmount the old on from your phone, stick the new one in and format the new one first?
