[Q] New microSD - Desire HD Q&A, Help & Troubleshooting

hello guys.
I have a memory card(Adata microSDhc 8gb class6) and I want to replace the old one(samsung microSDhc 8gb class2), because I think the new one is faster, am I right?.. and I want to know what steps need to follow to replace him or simply hand him the old with the new one??

The class 6 card should be faster, although bear in mind that the speed rating is a minimum so a quality class 2 card could be faster than a shoddy class 6 card. As for replacing it mount your SD card to your pc copy everything to the pc, install your new sd and transfer everything back, job done.

I understand, thanks. but I'd like to say your opinion if it's worth to make this change ?

for me no, samsung cards may not be the top of the line but they are good enough.
and the fact that it's only 8GB, getting a faster class cards will be worth it if you're getting those higher capacity cards 16gb / 32 gb.

ok thanks. remain with the old one ,and I will change when I'll buy a card of 16gb or 32gb. but are so expensive in our country :-<

Personally if you've got the card there I'd give it a go download SD-tools and benchmark both cards and keep the faster one, I find that faster cards do improve life sometimes with faster gallery load times and less likelihood of stuttering when recording HD video.

Actually i too had an 8 gb class 2 and i upgraded to 8 gb class 6. The problem with class 2 is that videos recorded at 720p start lagging when you play them with a class 2 card. I had this problem with the new sd card i got with my dhd. it was a class 2 and videos at 720p would lag like crazy. Got a new class 6 and the problem just disappeared.

What MicroSD are you using?

Hi, I have been searching on the forum in search of some information on MicroSD cards and came to no avail.
With my HD, it came with a 8GB Class 6 MicroSDHC. I think it needed it to play videos. I can't imagine using it with a slower card.
Now, my TP2 will arrive Monday and I would like to know the following:
1. Brand
2. Size
3. Speed (class)
4. Price
Is it performing well with the video playbacks or have you installed the SD Tuner software available for the HD?
What do you recommend?
Many, many thanks for any replies, comments and help!
Bought a A-Data microSD class 6, 4 GB at a local computer store.
Not the one i was looking for, i wanted the 8GB or 16GB but both where not in stock and the 4GB was less then 10 euros. I will buy a larger one in a few months.
With class 6 my phone isn't slowed down. A few years ago i bought a 2GB mini-SD, but my HTC Vox was slowed down very much. Didn't look to the class/or speed back then.
MicroSD cards based on SLC might be beter them MLC. IMHO i would always take a class 6 or higher card. However class 8 cards are hard to find.
I'm using the 8GB Class 4 card that came with my daughter's Nokia 5800 and it seems fine. Just watched an xdiv episode of Only Fools and Horses on it with no stutter or dropped frames.
I bought a class 6 off Ebay and it should be here on Monday so I can compare then
i'm using sandisk 8g class 2. whatched movies and played music, everything is fine. It only cost me just under tenner.
The performance diference between a class 2 or a class 6 is not that noticeable. However, at the price the cards are, I think it worths always to buy a class 6 card.
I bought a Transcend 8GB class 6 card. It cost me aprox. 20€.
The biggest differences I noticed between a class 2 and 6 card are:
-Taking photos is faster with class 6
-Browsing photos in sdcard is a bit faster also
-Viewing movies sometimes is a bit more smooth.
HastaSSSS
I have a 16GB class 2 Sandisk. I watch movies just fine. I figure with a class 6 i might be able to watch HD videos more smoothly.
Hi guys,
Thanks for all your replies. So from what you guys are telling me, it is always better to pay that little extra for the class 6 MicroSDs. But then again, is it worth investing in a 16GB Class 4 (no Class 6 available except the brand A-Data) or an 8GB Class 6.
16GB is nearly 4 times more expensive than the 8GB and yet it is slower. Shall I just get 2 8GB and hot swap the 2 cards as need be?
I bought a class 6 off Ebay and it should be here on Monday so I can compare then

I have read about this brand, and what others said was that their Class 6 under performs Sandisk's Class 4 Cards. Do yo notice any differences? How is the performance?
Also, I wouldn't recommend buying these cards off eBay. There are so many, fake cards on there. I know so, because I know mates that sell these cards. I would just buy from a genuine local store and pay a little bit more unless you don't care about performance.
Anyway, my last question.
What brand do you think has the best performance. Yeah, we can find out all the data about these cards on the web but it's nothing like the hands on tests from real users. So, will it be Sandisk, Transend, Toshiba, Kingston or the later A-Data?
Found a pretty review on the Sandisk 16GB C4 MicroSDHC cards. They compared it to the Kingston 8GB C4 MicroSDHC card.
Sandisk seems to be the company that is producing the fastest cards. It out performs Kingston.
But $133, is a bit steep. I think if I am correct a Sandisk 8GB C6 MicroSDHC is only $49.
What do you think?
You won't notice much difference between class 2 and class 6 as the device can only read at a certain speed, which is nearer class 4.
There are some cheap class 2 16gb cards out there, I have them and you only really notice if you install something like sdtuneup, but then again, you wouldn't notice much difference between class4 and class6
SanDisk microSDHC 16 GB Mobile Ultra works fine!
With the enclosed reader it is really fast via USB.

Cheers for the heads up about the TP2's read speed.
I was going to go for a 16GB class 2 but now might hold out for a class 4.
Haven't noticed any speed difference between my 8GB class 4 and 6 cards except that it's possibly slower than my Trinity but that may be due to the crummy TP2 stock ROM...

Please don't get two 8GB's, you will ruin the back cover of the device swapping the cards over all the time
My understanding is that the Class affects write speed, not read speed, so you won't see a difference playing movies on one or the other. You will see a difference in the amount of time it takes to get the movie onto the card (providing you aren't using ActiveSync, which will slow things down way beyond Class2 speeds).
I have a SanDisk Class 2 16 GB card on my Vogue and watch movies just fine with CorePlayer. Maybe a brief stutter once every 5 minutes or so, which I attribute to WinMo doing some other task in the background, not the read speed of the card.
In short, if it doesn't matter to you how long it takes to transfer large files onto the card, go with the least expensive.

Really? How much slower?
Yeah, I think I will go for 16GB for sure. The only thing now is what class. I am hearing 2 things here. I am worried about stutters on watching movies.
Some are saying speed only matters to write and not read.
But then I have read that it does matter, that is why there is a SDTuneUp for the HD.
I really don't want to buy a cheaper Class 2 card and only finding it is not working to my standards. I am pretty fussy about these things.
Any of you needed to install the SDTuneUp registry edit for the TP2? Do we need it? Anyone did any tests?

Check this out.
And this.
Class rating only refers to write speed, even though on the official SD association page it says "transfer speed." What they don't say is that it's transfer speed only one direction.

Hello ajbopp,
Thanks for your additional information. I think not a lot of people actually realise this. I always thought the Class Rating was how you determine transfer speed and not just write speed.
But there must be some ratings for Reading. Some cards are faster than others and that will certainly affect the rate of requiring information from the card, right? Because files are written in blocks and are distributed everywhere (fragmentation), so if the card is faster, then finding the blocks will be quicker, hence a better performance for reading movie files.
Just thinking logically how computer hard disk works. Not sure if that applies to SDHC cards. I also think the speed is also determined by the drive (the hardware reading/writing on the card).
There aren't many information on this. I have been searching around and most information I found was given by the companies that made these cards. Real tests are few and far between. Most websites I visited, tells me only of the write speed as I think that is what is most important to people who uses these cards, such as Photo Fanatics who needs speed for taking high end photos very quickly and for taking HD videos at 30fps. There is less need to know about read speed.
It's so confusing...
Got it yesterday. Thanks for all your help guys!
I finally went for the Transcend 8GB Class 6 Micro SDHC. Cost of only $187 HKD, roughly $23 USD. Didn't end up getting the 16GB as they didn't have any in stock and it costs 3 times the amount.
Without any tests, I just loaded my movies and it played very well. No dropped frames. No tweaks whatsoever.
Hello!
I had a TP with a Micro SD 8GB Class 2 card.
I'm considering buying a new one (lack of space available) and I wonder if I should consider a class 4 or 6...
I use the MicroSD to store software, pictures (camera), music (to listen), and some videos (to watch).
I don't intend to remove the microsd from the TP2 slot (have to remove the cover) so what I usually do is to connect via USB cable (data instead of AS).
So, transfering data like this will I notice difference with Class 2, 4 or 6?
I'd get a good price with this:
http://www.amazon.com/Kingston-Technology-SDC2-16GB-microSDHC/dp/B001RPD06I
is it good enough or should I buy a Sandisk or perhaps a Class 4 or 6?
Thanks
SanDisk and Kingston are both good manufactures.
Class 4 is faster than class 2 and class 6 is faster than class 4.
But on the other hand: class 4 cards need more power consumption than class 2 cards and class 6 cards need power consumption than class 4.
For this reason I bought 1 x 16gb class 4. That is the compromise of speed and power.

Again, this is only for write speed. I think it's an important distinction to make, especially if you are hoping for better video playback because of a faster card. The class of the card is not likely to have any impact on the device's performance, either video or anything else (other than file saving/writing operations).
so... for my kinda use there is no need for a class 6 right?
do you think a class 2 kingston MicroSD 16GB can be used for what I want?
playback music and some video... storage ... navigation?

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?

[Q] Why class 6 SD card?

Hi all,
I've read in a few places that if you want to run apps from your SD card that you should have a class 6 SD card. Can anyone explain why this is? I've currently got the one that came with the phone, which is class 2. Just want to understand why I need it before splashing out the cash
Thanks
It's all about speed. Class 6 is faster than Class 4 is faster than Class 2. If you are happy with the performance with your Class 2 card, no need to splash out the cash.
yeah its just about speed, the higher the class the faster the r/w speed, you dont really need a class 6 these days tho, maybe in the old days of the g1/hero but not now
There's quite a bit of discussion on this and I'm honestly quite confused over this as well.
The higher classes just means faster write speeds but same read speeds. Certainly, this shouldn't affect the performance of apps that are installed on the card; unless the card is being used for swap memory.
Anyway, I've heard some users with 32GB microSD card (only available in class 2) using app2sd with no ill-effects. I've recently purchased one myself and will be swapping it out later tonight.
newbie on Android here.....may I ask....Im currently using a 16Gb mem card....If I change it to a 32Gb, what are the files that I need to copy to the new card, so that the apps/games currently installed will still run? I noticed there are so many folders inside my memory card now.....which one should I transfer to my new card? Or should I need to re-install the apps?
thanks..

Before the usual flamers get to write on this topic to say high-class cards are useless, it really comes down I think to the time you have available to wait for USB transfers. On a class 2 it takes AGES. I bought a class10 16gb and it's an absolute life changer (i do have a lot of public transport so I make heavy use of my phone as a video player)

Another reason to have a class 4 or faster card in the phone is to have reliable 720p 25fps video recording. On my Class 2 with a2sd+ recording stutters.
thanks for the responses. from what i read previously, it talked about class 6 cards being less likely to be unmounted and causing problems to running applications. does this mean anything to anyone?!

This is the reason when I eventually get the money I'll be getting a 16GB class 4 or 6 card. At the moment 720p is fairly pointless to me since I can't get smooth recordings with my SD card.
Have no issues with my 16Gb Class-2 sdcard. R/W speed enough to handle 720p recording and rockplayer playing avis perfectly.

Are you running A2SD or a2sd+ on your phone? If not, that may be the reason.
The more apps and widgets and stuff is moved to the sd, the more r/w-access happens to the card, which has serious impact on video recording. I really wish the internal memory of the Desire wasn't so small. What the heck did HTC think by putting only 560 MByte internal storage into their android flagship? The SGS has 5 GiBytes!

Incorrect!
The class of the card doesn't tell you the speed of a card - it tells you the *minimum* sustained write speed on a card which is completely unfragmented
A good quality class 2 card can and often will be faster than a poor quality class 6 card.
The two Sandisk Class 2 card I use both write at around 7.5mb/s, which is faster than the class 6 minimums.

Dave

That's interesting info! Would explain why I have far fewer problems than most people report with 720p recording onto my class2 card.
So the real answer is: Benchmark your write speed before making any big purchasing decisions on SD cards.

[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

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 .

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.

I am having an 8GB class 10 Toshiba MicroSDHC with technical reading speed indicated at up to 25mb/s and writing speed up to 20mb/s but I usually can only get slightly more than half of its full speed capability when running a benchmark Is it because I did not perform an initial format for the card or the Play does not support such hi-speed transaction?
It has been proven that the Xperia PLAY and probably other phones as well have problems with Class 10 cards. The problem with Class 10 cards is that, while they have super high speed writing capabilities, there goes a trouble with reading speeds. It has been proven in games in which during gameplay, the games that were tested lagged to the point of unplayability while they are trying to read game data (or SD files, more commonly) from the card.
Users here mostly recommend Class 2 and 4 regardless of the capacity.
PS: I can live with Class 2 microSDHC, so why can't you?
Well, I was attracted by producer's advertisement of their so-called fastest microsdhc in the market and did not know the fact that my PLAY does not handle such speed.
Since I already bought it, do you know if there is any solution now to overcome this problem and utilize the full capability of the card' speed?
honestly, i don't know. first things first when buying new hardware, read and read and read and read and read and read a lot of reviews until you are satisfied. never read company claims because they are just marketing strategies, ALL LIES, rather, read user opinions.
since you bought it already, all i can think of for it to not be wasted is to just buy a card reader for it and use it as a flash memory stick for your laptop or desktop instead. i mean use it like a regular USB flash drive. that's just my opinion though. you really can't stick a Class 10 card on the XPlay. all hell will break loose.
start looking for class 2 or 4 instead.
So sad...I thought I could somehow improve my PLAY performance. Anyway, I think I will use it for my Digital Camera instead and start looking for the class 4 one as your advise.

Class 10 cards are KILLER in a digital Camera. I use one in my Canon Rebel T1i and continuous shooting works so much better and faster with a Class 10 card. Also much smoother video recording if you record in HD.
BTW the best card for this device is the Sandisk 32GB Class 4 card. Buy from a reputable seller as fakes are out there...
I am currently using a Sandisc 32gb Class 4 card and there are slight lags on Modern COmbat 2, my old card was a class 6 16gb card. I saw better performance on the class 6. I am aware of the class 10 issues. My question is I am currently using SD card speed increase software to cahgne the Android cache size from 128kb to 4mb, is this software make a difference? Just curious to get peoples input.

i'd stick to class 2 if i were you, it's slow when writing (but that's already fast for me), but it's fast when reading.. at least no lags when something operates within the card..
and oh, is it true that SanDisk get their cards from random unbranded producers then label them with "SanDisk"? If so, then I won't trust this brand anymore..
what is the best brand then? they say it's only between SanDisk, Kingston, and Transcend. But my sister had problems with Kingston USB Flash drives where they periodically corrupt files and have slow writing/reading speeds and that gives me a negative feedback on the whole company. as for Transcend, i think it's too cheap that the quality might be substandard.
I'm still using the stock card that came with my Play (i don't know but it doesn't have a brand) and it's doing its job pretty well. i'm considering an upgrade soon.

It is a great information indeed. I am more confident for my next choice of card now.
Problem with high class SDHC cards is that they're good at big files, but suck at small files like game data files on phones.
Class 4&6 are the most versatile for all the various things you might do with the phone.
Also, I've always found SanDisk to be the most reliable.
