[Q] best 32gb for dual boot?

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.

Which class micro sd card works best for rooting from sd card?

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,

I use Kinstom 32GB class10 early. But when I take photo, some photo maybe have error.
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.
or that's Kinstom's problem. I don't know.

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.

Using a class 4 32 GB Kingston since a few days, working nicely. Got 5.5 MB/s write, 12 MB/s read. Thanks for the info, I was going to buy a more expensive (and I though, more future proof and safer) class 10 one, before I read about the compatibility problems with class 10 here.

using class 6 non brand. Works perfectly with 2.3.4 CM7

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 :/

According to HTC's website, the HD2 can support up to a 32GB SDHC (class 10 i believe)

Yes. You set up two partitions 32 gb each.

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!

Help for sd card

Hello can you tell me please if this memory card is fine for windows phone 7? thank you very much
http://www.ebay.it/itm/San-disk-16G...emory_Card&hash=item3f16a59483#ht_1293wt_1103

will it work?its hard to say.There is a thread for confirmed working sd cards on this forum have a look to see if it is on there but then again all the sd cards on there are not guaranteed to work on yours as other factors may play a part so basicslly some will work for some which dont work for others..its all about trial and error my friend. Stay away from fakes. I have a 8gb sandisk class 2 which dont work for other, you know what i mean.

I just bought a 16gb sandisk today and I'm currently running WP7 tango(HD2O's ROM) It works great.
