hey guys im new to the hd2 threads and i want to dual boot windows phone 7 and android and i just want to know what kind of 32gb sd cards are the best because i want to partition it to where windows will have 16 and android the other 16 thanks in advance
I wanna bump this but re-phrase his question a little bit.
For anyone using a 32 GB SD card or have tried it for dual booting WP7 and Android - How is it performing? What brand would you recommend? Does class make a difference?
I searched and came to this thread. I have an idea but would like more input in this matter. I need more feedback to make the best decision possible because I plan on triple booting into Ubuntu but sorely lacking space right now. Thanks. And don't be shy to reply.
I'm guessing sandisk, but hold your horses.

Really? I hardly found Sandisk with class more than class 2....
There is a thread that shows the different speeds for sd cards. I found that class 2 Scandisk 8gb is the best preformer.

So have you given 32gb sd card a try? I'm not looking for speed and don't mind a lock up, hiccup, or even random reboot once in awhile. I just want something that works, minimally, at best. Now, if it works but there are constant problems and prevents me from doing certain things on my phone then forget it. I'll have to somehow make room for ubuntu or just plain do without it.

I have a PNY Class 6 8GB MicroSD for my phone. I was wondering what are the benefits of a2sd, and what are the benefits of a class 6 SD rather than a lower number? I don't currently use a2sd, and wondering if i should.
lower number is slower. iirc, the Hero supports speeds up to class 6, which is faster then the phones ROM

Ok, that makes sense, but why should I use a2sd? How is it better than storing them on internal memory?
if its a class 6 it will load faster.

Ability to have more apps installed, as well as not having to wipe all the applications when you flash a new ROM (although some require you to wipe the ext partition, the ROM chef will tell you if you need to wipe the ext parition (where your apps are stored).
I didn't think I would ever need A2SD until I got to my limit.
I have not noticed a drop in performance opening apps with A2SD on my class 6 card, if there is, its milliseconds.

A2SD moves all of your installed apps to the SD card. If you have a class 6 card, which have a faster read and write speed than the internal memory in the phone, it makes everything run a lot faster since it doesn't have to run everything from the phone.
sorry to get off topic a bit, but ive been looking for a good class 6 card. the only brand i have seen is a-data i believe for about 20 dollars. im not really looking for something that has a large capacity. in your opinion, which one is better as far as brand? and how much did you pay for your card?
One thing to remember though is that class 6 just means it is certified/guaranteed to transfer at 6MB/sec or faster. A class 2 card can still be as fast or faster than a class 6 and there are some out there that do just this.

I wouldn't... every A-Data sdcard I've ever bought has developed bad sectors almost immediately.
Sandisk is the standard, but a class 6 SanDisk is hard to find. The last few I bought were Transcend.
How do you tell what class your card is?

It's on the card itself. It's the letter C with a number inside it. That number is the class number.

thats what ive always been looking for, but as you said its hard to find. if you dont mind me asking how much did you pay for your card and what size is it? also, thanks for the heads up on the a-data card.
I read a review not long ago about sandisk class 2 cards. the tests they ran on them showed they were the equivalent to 10 mb/s. of course you would have to get the right batch number. does anyone know a site that tracks this kind of info?

Depends on how you use a2sd.
If you move dalvik-cache to it as well as your apps it'll be a lot.
But the total amount depends on the number and size of the apps you have installed. I'm sitting with 126/160mb free on Internal Storage.

+2 I have a Class 2 card and I get around ~7+MB/sec, I'm tempted to bump it up to run A2SD more aggressively so that my phone's faster.
i was thinking about buying a class 4 16 gb Sd card.. will this help at all i am not running app2sd..so will the sd card make any difference??
Will it make my screen run smoother and fast on Damage Control 2.8??

If you're not using a2sd it probably won't make much difference either way. If you're thinking of running a2sd later spend the extra 10.00 and get the class 6. regardless of the people talking about their high speed class 2 cards, you'd have to be fairly lucky to get those speeds (as someone else noted, depends on the batch of cards) with class 2, or 4.
an also if i run app2sd if i pull out my memory card at anytime will it mess up my phone??
and i have the 1st class right now so upgrading will make no difference when downloading apps to my phone or anything like that??
I recently bought a 16GB Patriot MicroSD card, class 10. I find that after 24 hours of use, things start to fall apart (I've tried several different SD builds). I also have Sandisk 16GB Class 2 card that runs my daily Android software; never had a problem with it in 2 months. I follow the same procedure when attaching the card via a reader and removing it from my computer. I also use the same procedure when attaching the phone to my PC. I have concluded that the new Class 10 card is failing. My questions are:
1. Is anyone using a Patriot 16GB Class 10 card with success?
2. Can you give me an opinion of the best 16GB card when using Android on the HD2?
3. Could the Patriot card be too fast for the HD2?
4. Is there a maximum class rating I should not go over?
Thanks in advance.

Same is true with my very old Adata 16gb Class 2. But, I was hoping to get a bit more speed.
I think class 10 is too fast (and expensive XD ) for the HD2,
I got Kingston 16GB Class 4 and it works perfectly.
Hey all. I've got a 16gb Patriot class 10 installed, been using 1week now with no issues, Cotulla's Nand stock desire rom. Seem a little faster than the stock provided card, not sure if was worth the $ for the slight boost though.

3/19/2011 - my 16gb patriot still no issues. Mine has been formatted multiple times and been re-partitioned with ext3 and even split for dual boot wp7 and hyperdroid gbx v7 and now v9 and have noted no sdcard related problems. Have downloaded and deleted multiple apps, and currently have 6gb of full DVDs on it. Have noted with all SD cards, you gotta pay attention when you're instructed to mount/dismount card via phone or when in mass storage mode connected to PC via USB, or when in PC using card reader or data can get corrupted. Hope this helps.

Hmmm, I absolutely can't seem to keep it from crashing. Right now I'm experimenting with another class 2 card to see if I can manage to destroy the installation again. Glad it's working for you. Might the difference be that I'm running an SD version from the card using the current stock HTC ROM?

I was using an 8 gig class 2 that I have misplaced. It didnt run too well and my nook was laggy. I am hoping to get an 8 or 15 gig card. Which class will work best for rooting? Thanks

Strictly speaking any microsd card should work for rooting the B&N stock install on the built in memory. But if you are talking about booting from microsd and running a ROM, you want a Sandisk card.
I've noticed you've started a few threads now that could have been avoided with a little searching. Talk about microsd cards can usually be found in the first two pages of the Accessories subforum just by skimming the titles.
Most of the common topics will show up in the first three pages of any given forum.
Happy Searching,

After that I check for internet about it. Someone said that maybe Kinstom's problem. It's not stable.
Now I use the Sandisk 32GB class4.
Maybe defy not support class10.

I bought a Team 16Gb Class 10 micro SD and it freeze my Defy, but I read that all Smartphone have trouble with class 10 cards (maemo and WP7 too).
It's something related to voltage (if you use setsvel to undervolt) and with partition (you need format the card with 32k or 64k)
I think Class 4-6 will be enough, until the Android Kernel will support class10.

Did you mean SD Class?
Just look at the card, it has either a 2 or a 4 or a 6 in a circle stamped on it. Thats the class. The class = the number of MB/S it can transfer.

No. Class=speed only. He said the partition have 32K 64K.....I think that is not Class. Because the class can't change when you format the sd card.

If you want to find out what partition your card is just plug it into your computer then mount as SD storage. Right click on the card from "computer" and select format. The default settings your card is set at will be shown. You can change it to other sizes, and formats (like FAT, NTFS, but FAT32 should be default and used for phones). I recently formatted my Samsung 8GB class 6 at 4069, and no issues so far. Don't worry it won't format unless you select to format, so you can do this just to check.
Hi there, because of this thread i bought a class 6 16GB Trancend SD card. Formatted it with 64kb clusters now have 11,2 Write and 21,9 Read speed (in SD tools).
Thx you all for the advice not to buy a class 10!

I'm really not certain about this, but their a limit on the size SD card our hd2's can support. (Either 16 or 32gb which is what I'm uncertain of) try formatting your new SD card into two 16 gb partitions and then see what happens.
Hopefully either that helps or someone with more knowledge than I will comment and give you a better answer

Well the limit is definitely not 16gb because I have one of those and it works fine in Android but it for some reason cannot boot SD Android. Also, if I'm not mistaken MarkAtHome (I've seen him in many of the NAND threads, especially NexusHD2) has a 64GB SDXC card as he was posting something about that a while ago. He'd have to confirm though.

Where did you get your memory card?? You son are a victim of false advertisement. I purposely purchased a "cheap" 16GB sd card from ebay and it wasnt even bigger than like 300MB. There are ways to fake the memory size, and thats why when you try to put the music on your card is says its not there because there truly isnt any physical memory available. And also why it gives those weird readouts. Sorry to bust the news :/

There have been threads discussing how certain sd cards do not perform well in android devices, including the HD2. It has to do with some of the access times the cards are rated at.
I have tested a 32gb patriot class 10 card in the HD2 and samsung vibrant that made both phones freeze and run terribly slow until the card was removed.
Sandisk cards run flawlessly in the HD2 and I have only been using them for the past year, including a 32gb and a 64gb SDXC. The 64gb must be formatted as fat32 inside the phone before it can be used, but the full 64gb is available.

I agree with elesbb. Infact the same thing had happened to me about 4 years ago. What they do it put a memory hack in the SD card fooling it to think there is more memory. I would say if you bought it from ebay contact the seller first and
tell them you think it might be fake and you wish to get a real card asap. If they don't send you one or sound like they may be un-willing to then you should report them. Here's some information found on ebay's site about fake memory cards.
If you bought it from a different online seller you should still contact them about it and say you did some research and believe you recieved a counterfit item. In the link i shared above there are a few examples of how to spot fake cards including some pictures if you go through the links. I've read somewhere that if you have a sandisk and the class rating is in the corner then you more then likly have a counterfit one. Sandisk's class ratings should be centered in the middle of the SD card.
Okay, i've just sent email to him, hopefully he will just re-send me new, (working..?) or give money back!
