Hi all,
I'm going to finally have some spare time this weekend and might even get to have a mess around with Android on my HD2 if I get lucky! My concern is that I have a 16GB Class2 microSD in my Leo and while looking at HD2 stuff on ebay came across this.
The seller states that Android won't run (properly?) on his 16gb Class2 and includes a Class6 8gb card aswell for this purpose.
What's everyone's experience with running Android on a slower card? From looking around I've seen people saying 'there isn't much difference' for most things but a lot of contridictions for others.
Thanks gang!
I have no issues with my Android build currently, and it's on a 4gb Class 2 SD card.
It does help having a faster one, but It's not the end of the world.

Have been testing out froyostone sense build on a 2gb class 2 card and it's like lightening So yes, would format first though otherwise you will get lag.
Cheers - yep I won't forget to format, been reading the threads while working this week... taken in loads of info, just need to find the time to actually get it rolling
I was wondering the same thing. I installed froyostone 08.07.2010 using miri Rom on stock radio on a friends hd2 and it freezes and comes back to life very often. Would a higher class sdcard solve his problem?
I think they guy on eBay is talking rubbish. I run darkstone's 2.2 perfectly well on a 16GB Class 2. A Class 4 would probably help a little bit, but I'm not that fussed really.
I'd be more concerned about getting dodgy copies of Transformers from them!!

The whole OS and all animations etc, or just touch screen response?
If its the touch screen, that's a known issue and will be addressed in due course.

A Little more information would be useful, what's not working about it? How's it formatted? Has it even been formatted and then had a new build copied to it?
Phil
i never had issues with a class 2 before... no SOD or anything... although after switching to class 4, there is noticeable speed. now in class 10, a lot faster. but no real issues in class 2 except a tad slower (but decent speed nonetheless)
I use the 16gb class 2 card and its quick with decent quadrant tests. I think its because android loads into ram (please correct me if I am wrong, ill search for this later). I think there are apps that read or write to folders on the SD card that would gain from speed of a class 6 or 10 card and if I am right about loading to ram the boot up time could receive a benefit.
Personally I am looking to get one just to access media faster and for taking pics and vids as there is a write delay that's typical with all phones. If it helps android in its current state the cool but I'm not in a rush. Development here have made great strides in making android snappy and android is an awesome is as it is for handling background tasks. Much to the credit of Linux but I find android to be a faster evolution then most mobile oses. Much to the credit of being open source and encourage community development. Nothing here is illegal but maybe some grey areas in closed source distributing which cyanogen had an interesting situation that was resolved quickly with Google's assistance.
But I am off topic now. Yes it would help with some things but don't break the piggy bank over it.
Hope my thoughts are helpful. It would be better to get feedback from those that have done it and get before and after boot, quad, and market download responsiveness tests. I may have a class 6 8gb card somewhere I can test later tonight. I would do fresh sdformatter formats with nothing but android on the card to get a somewhat standard benchmark.

the touch screen. The SD card was quick formatted. Would that make a difference in the builds performance ?
I'm using a Kingston class 2, but it performs with 5,5MBs writing speed when used in a computer slot, so in practice its a class 5,5. Works great! Froyostone sense v1

You have experience with your G1, the class 6 I use on mine makes definite difference when running apps from your sd card. I've been alternating using my 16 GB Class 2 and my 8 GB Class 6 in my HD2 but I haven't seen any speed difference with android so I believe that it runs on the internal ram.
i think class 2 is enough

Touch Screen lag/freezing is a known issue right now and doesn't relate to the SD card.
It's being worked on.

I have a class 2 16GB sandisk drive and score 1578 in quadrant standard, that said i usually get write speeds of around 6MB/sec on my computer
i personally think it helps a bit ( i ws previously running Android off the 16GB class 2 card the HD2 came with) but experienced some lag when scrolling.
That said, it was an early build of Android so it was probably just that.
The thing is, 8GB class6 cards are relatively cheap to buy (i picked up an A-DATA 8GB class 6 for $21 canadian at CanadaComputers)
so..why not upgrade to the class6 card? I'm sure it wouldn't hurt and no matter what you'll experience at least have SOME sort of performance gain in other aspects (music, pictures, file managers, etc)
OK so I've been running many version and builds of android since day one on my tmous hd2. At first it was with the stock 16gb sdcard, (till it got corrupted, LOL) so then I switch to a 2gb I had around. I have only formatted this 2gb card once in the begging and never again.many times I have deleted the android folder and many times I has switch to new builds ( I think I try everyones.latest I been using n very stable JDMS 1.3) n haven't had any issues. Like freezing or SOD. Now two days ago I help my friend with his and his wife's tmous hd2 with the 16gb card. So I did a fresh format fat32 then flash the same rom (ozDroid) and radio I been using for months. It results they are getting freezes and occasionally SOD. So for a test I took my wife's tmous hd2 with 16gb card did the hole setup an guess what the freezing and SOD is the more often..when I don't get any with my sdcard 2gb. Could there be an issue with high capacity cards. And could that be the reason why many tmous have the more problems with freezes and SOD

I use stock 16gb and dont have those issues.

this is common knowledge in the IT field. the larger the card, the more slowly it will write and access small files, such as the files needed to run android. take 100 small text files and copy them to a 256 thumb drive, and an 8 gb thumb drive. you can copy them all to the 256mb drive, and delete them all again, before the are all copied to the 8gb thumb drive. the 8 gb drive, will work much faster copying an .avi, or large file than the 256, but it sucks at lots of small files.
but it's good that you're posting your exp here. many people would not know this otherwise, and may stop experimenting with android due to frustration, when all they need is a $10 2gb card from walmart.
another couple tips when dealing with solidstate memory. just like a harddrive, files can become fragmented if you have multiple tasks or file transfers going at the same time. to avoid this, make sure each is done before starting another set of files. next, do not defrag solid state drives. they only have a limited amount of times they can read and write to each sector, and defragging, and excessive copying/deleting, wears down the material, and kills sectors of the drive. and last but not least, watch your battery. just as it says not to attempt an install with less than 50% battery, don't run your phone down to a dead battery when possible. because your booting of the microsd, it's constantly being accessed by read and write functions, and if the battery dies before it finishes writing, you get corrupted files, and you'll have to do your install all over.
No lockup or freeze with 16GB.

Same here. 16 gb SDHC, no problems.
I haven't noticed any difference between a Class 2 2gb, Class 2 16gb, or a Class 4 8gb - they all run about the same with not noticeable differences in boot time, smoothness, or SODs, even though the class 4 is 2x as fast.
hi guys,
before you post any comment, you can grab a none SDHC card, and do a comparison.
if you have benchmark software, please look at the "access time", the None-SDHC card always faster than the SDHC card. not the speed, but the access time.
after I change to 2GB SD Card, I never meeting any sleep, lag program with any version of roms.
if you don't have none-SDHC card, please do not make any conclusion.
16 gb class 10 kingston sdhc
works great
compaired a class 6 no name 8gb sdhc and the stock 16gb class 2 the class six lags less than the class 2 but the class 10 16 gb kingston is super fast
I am using class 4 8GB and 16GB, no diffrence found.
I can confirm, going from 16gb to 8gb, I've had far less issues with the 8gb card using the same setup. 0 SODs when I'd get them daily with the 16gb card. May or may not have anything or everything to do with it, but I'm sticking with the 8gb card. lol
My experience has been that performance has been about the same whether using a 2 GB SD card or a 16 GB SDHC. However, it seems that my 16 GB card was slower at one point because I had an excessive number of individual files on it. It's a double edge sword because you have all that capacity but the more you use it the slower it seems to run.
I had this issue aswell but I updated my radio to 2.12.xx.xx. and since then I have not seen any performance issue due to the SD card size.

That's very presumptuous of you.
I fixed all of my lag and screen freeze problems with a combination of setCPU settings, ADW launcher settings, and updating my radio rom.
Before I finished doing all of that this morning, I'd get a freeze from wake fairly often. Since then, not a single freeze, and trust me, I've been trying to get it to freeze up.
Believe what you will my friend, but punishing yourself with a 2GB card just seems silly when people are outright telling you that the size isn't the problem.
Good luck either way!

Yes ur are right with the new builds and using setting and programs like setcpu or even auto killers will help eliminate this problems. But I I said in the first post was that high capacity cards tend to give u more problems, using my 2gb (I think all the way to 6gb is non high capacity) I have no need for such adjustments to whatever build I use..u can read post 2, is very well explain there.

My 32GB did worked only one time, after first reboot i cant use android. But 2gb works like a charm
Anyone else experiencing a slow device? Some apps take forever to load, some pretend they are loading then I am thrown back to the start screen.
Going into things like people, or market place takes ages, and the screen sometimes freezes up for a few seconds while it fetches data.
I also find that after waking up the machine I have to wait about a second before I can scroll up the keylock or the screen doesnt respond to my touch.
Is this the norm for most people? Its tolerable, but extremely annoying.
When they work, the graphics are smooth as silk.
Also, downloaded need for speed from the app store and find the sound to be very choppy, to the extent that I have to shut the music off for the game to be playable.
Haven't had any issues of that sort here - Everything has been running smooth and fast - I am using 8G Sandisk card - Been playing need for speed and it has been smooth as well -
Its been smooth as butter for me. You may need to try a different sd card. Only certain cards work well for wp7... they have to have a good random access speed.
I had been using WP7 for almost 2 days without live services on a 2gb card, then once I got my code and activated live services, everything was a bit chuggy. I reflashed with a 16gb card and everything is now super fast and smooth, so you may need a larger card possibly?
I'm having the same problems as well. Phone was really fast until I put an SD card in now it lags alot and some apps look like they are about to start and then shut down.
Can some one who's phone is running without any lag try installing Endomondo (free GPS running app) and see if it starts on your phone. This would indicate its my Kingston 4GB SDHC class 4 card.

i used a 16gb class 2 at the first time and the system is laggy. now i am using a 8gb 6 class card, it seems normal now.
hmm it doesnt seem to make much sense. My card is a 16gb class 4.
I have a 6gb class 6 I could try, or a 16gb class 2.
I would have thought class 4 would be good.
Just a real pain to have to go back to square 1 with a hard reset, then unlocking, bla bla bla.
I just assumed that what I am experiencing is the norm for this port, but apparently not.

You can just turn your phone off and swap the SD cards, then reboot. It should format the new card for you.
Oddly enough, I just took my mem card out to check the class printed on it, popped it back in, and now my device is running as smooth as silk, no lagging, aps load very quickly.
Wtf gives?!

Sandisk class 2 cards seem to work well. I've heard that higher class cards sometimes has speed tweaks done to them to make write speed higher, but will lower the random access speed, which is what wp7 needs. I'm using sandisk class 2 16gb and it works great for me.

I took it out and in while the handset was still on.
But, in the last hour or so I decided that maybe the mem card was not good for win7, so I formatted my class 6 16gb scandisk, did a hard reset, went through chevy unlocking, etc etc (ive done this so many times now I have got the whole process down to under 10 mins
Now the handset is the best its ever run, fast, smooth, no lagging.. I had convinced myself that the laggy version I had before was the norm, so this truly is like having a brand new HD7.
It only took 2 days, and about 18 man hours, but finally (knock on wood) its complete and im a very, very happy bunny.
I also hope this clears up the battery drain problem too.
Crazy how a tiny bit of plastic can be so problematic and critical to the whole handset working correctly. No wonder Microsoft have locked down the SD cards inside the handset, but great that we have the option to upgrade and reset unlike iphone.

Can you tell me what the model number of your Sandisk memory card is and keep us updated about the speed of the phone or if the laggyness comes back. This could be a big help for user having a laggy phone, like me.
Oh and does wifi work with this card now?

I thought it might be written on the SD card.
I was searching for a 8gb Sandisk card model number SDSDQR-8192-A11M as thats the one Sandisk listed as compatible for Windows Phone 7 but I could only find the 8gb card model number SDSDQR-8192-E11M.
The difference between them is the A is class 2 and the E is class 4. I think I'll just get the E one and give it a go. It's only a few quid
cheers for your help!
A quick flick to scroll seems to be impossible. Does anyone know the registry tweak that edits the initial scroll lag? Thanks!
Searched but I cant find it?
Does no one know? Everyone is looking but no answers. lol.

um yes, thanks but no thanks. I have a compatible sd card. if it isn't i wouldnt be able to use wp7.
my card works and has always worked. even with android i had no problem.
So you're telling me you have super fast flick-ing action? I highly doubt it.
Anyone else with a better suggestion?
Yeah, I have one - change your SD card.
I have great scrolling, no lag at all. The SD card makes a huge difference. When I was using a class 4 kingston, wp7 was laggy and didn't run that well... it still ran and used the card, though. But now using a class 2 sandisk, wp7 runs as smooth as butter... no lag and battery life is much improved. What kind of card do you have? Cards with good random access speed is what you want for wp7... usually lower class cards have better random access speed than higher class cards. Class 2 sandisk seem to work consistently well, but I guess some people have had issues. But even cards that are same class and same brand, but have different manufacturing numbers or serial numbers will be very different performance wise.
i have a sandisk 8GB class 4. it has never had any problem.
are you guys telling me that by downgrading to a class 2, i may have a faster WP7 OS?
that is ridiculous!
can anyone confirm this?
I'm still using Class 4
I will backup my data and test this tomorrow.

You might... it really depends on the sd card. Sandisk class 2 cards made at one time can be very different than sandisk class 2 cards made 6 months later. Same with class 4 or with any sd card out there. When it comes to the random access speed, it can vary greatly... manufacturers don't test this speed and don't aim to make consistent scores of that. But usually the tricks that manufacturers do to get better sequential write scores on their chips end up hurting the random access speeds. That's why more class 2 cards are compatible and work better with wp7 than class 4, 6 and 10 cards. And if you are having lag, then that means you can definitely do better, because I have no lag at all at this point... maybe every once in a while I'll get a little lag here or there, but overall, it's VERY smooth. I haven't installed my apps yet... only like 10 or so apps from the market, and only copied one music album over so far, so maybe I'll get more lag when more is installed... not sure. I have 21gb partitioned over for wp7 on my sandisk class 2 32gb card. When I was using a kingston class 4, I definitely had a lot of lags and I hadn't even installed anything at that point. But I have heard that sandisk class 4 works good, too, but, like I said, when and what factory the chips were produced in can make a big difference with the random access speed which is what wp7 needs to be smooth.

It's all to do with your micro SD card, my old Samsung 8gb card, ran ok, but would somtimes lag, not load marketplace, things would crash and the occassional autoreboot as well, so I ordered one of the Microsoft recommended sandisk 8 GB ultra microsd cards, not a single lag, no crashes, things run so smooth and fast its really quiet amazing. How ever many times and different ways you format your card if its not the right one it will never run wp7 smoothly

You should take the class 2 sandisk back and order a class 2 sandisk from somewhere else... most class 2 sandisks work great with wp7. But like I said in several other posts, just because the brand and class are the same, doesn't mean the card will perform the same. They don't test the random access speed on cards so it's not consistent on cards, and it's random access speed that matters with wp7. I was just testing my cards today... I have one class 2 16gb sandisk with great random access speed and works great in wp7, and I have another class 2 sandisk that has bad random access speed and makes wp7 laggy. The read and write speeds were the same on the cards, though. My class 2 32gb sandisk has good random access speed, and my class 4 32gb sandisk I just got yesterday has even better, but my old class 4 sandisk 4gb card has terrible random access speed. My class 4 32gb kingston and my class 6 8gb kingston both have terrible random access speed as well.
Cards of same class from same manufacturer can have different chips made in different factories depending on when and where they were made. Also, a lot of the time, the chips the they make to have higher sequential read and write speeds will have worse random access speeds, so you will probably have better luck running wp7 with a class 2 than with a class 6 or 10. Microsoft reported this from their testing of memory cards for wp7. This doesn't necessarily mean a class 4 or 6 card won't work just as good or better than some class 2 cards, and it doesn't necessarily mean a class 2 card will work well. The problem is that the random access speed is not rated for cards so it's not kept consistent on cards. But at this time, it seems the class 2 sandisk seem to have the most consistent high random access speeds, but again, doesn't mean all of them will. Like I said, I have a class 2 16gb sandisk that doesn't work well (which is the one I bought retail), but the class 2 16gb sandisk that came with my phone works very well. Also, I just got a new class 4 sandisk 32gb card which I haven't tried for wp7 yet, but from benchmarking the card, it looks like it will work very well. I'm gonna test it with wp7 tonight.
I used a sandisk 8gb class 4 when I first installed wp7 but I thought I should make a dual boot and I bought a samsung 32gb class 10 microsdhc.
wp7 couldn't load and I got a message the memory card wasn't compatible...
right now I use android and everything works like a charm but I would love to do that dual boot.
I there anyway to fix that except buying a new card?
format card with SDFormatter v3.0, insert to phone and do hard reset with Volume Up and Down together and power up... maybe not help but you can try...
i use Sandisk 32 gb class 2 and card is very fast and stable under WP7, faster than Sandisk 8g class4 from original HTC 7 Pro device

There is a huge amount of info out there on what cards to buy, but none of it is 100%, it still might not work, and going for a class 10 card was probably the big mistake, dont get me wrong, some folk have them working, but generally WP7 tends to like class 2/4 and potentially 6 the best, its believed its to do with random access speeds which are usually lower on higher class devices
tthere has been some development with cards that install but sometimes reboot, some small reg tweaks have had a positive effect, but cards that do not work at all is going to be very unlikely to get working. you can format it all you like but the installer will clear all partition tables and set new partitions up, meaning it wont make much if any difference.
ive spent all week looking at new cards, crystal disk mark seems to be a good judge, but if you dig through the net at revews and forums you'll see why its very much hit or miss, the bench marks are all different. Bt the more you look at and the more a given card looks ok, the higher the chances of it working. Ill tell you saturday if mines any good, but i physically couldnt do any more in identifying a working card, so its an educated guess
in answer to your question, no, you need to install WP7 first, then partition it and install SD android, so unless you can get WP working you'll not dual boot them, send the card back, say it wasnt working with your camera or something
