[Q] Fastest SD for Android on HD2

Hi guys i have been using
FroyoStone Sense - V2 for couple of days now and with basic winmo install, so far I love it.
Although it seems to slow down when more stuff is opened also when using Astro for file explorer.
Since this android build is all running from the SD card are there better cards like faster ones? I'm using the original 16g that came with my T-mobile phone. Is that the fastest i can have for that phone?

what's your sd card class ?

Class 2 i think

im usung a 4gb class 6 and its screaming compared to my friends using the included (class 2) 16gb cards.
so yes the speed of the sd card helps, they go all the way up to class 10

ok thx looks like im getting new sd

Class 6 seems to be the most popular. I went with this one.

wait till the nand rom comes..it will be there soon
DN41

im not sure i want an incomplete rom in the nand.

I'm using a 16gb Kingston C10, and yes it's really fast, compared to my old
16gb sandisk C2.

Ok but now I need to transfer my android and all the stuff to the new sd
should I just copy over all the folders and thats all?
I want to keep all my settings cotacts, apps and more!

Problem with unrooted legend froyo 2.2 8gb sdhc card.

Hello everyone,
This is my very first post. Sorry if its redundant one. But i couldnt find any thread with this specific problem.
Here is the thing, i bought HTC legend just 2 weeks ago. I have unrooted legend with Froyo 2.2 vodafone update. Yesterday i bought Kingston 8GB class 4 microSDHC card. I placed it in my legend. It detects it no problem formatted it. But it seems whenever any application tried to write to sd card. I get the message "SD card unexpectedly removed".
I have tried formatting card with Panasonic sd card formatter . Tried formating it under windows. The card works fine on PC read/write. But for some odd reason phone can only read from it
Also stock 2gb card is working like a charm in phone.
Please Help!

Try with some other brand
Usually Kingston has lot of duplicates especially in India

Yes i did consider that possibility. But the thing is card is working perfectly fine in pc. I have 3MB/s write speed when i copy things into card using pc. So if card was not original it shouldn't work even under windows. It just doesnt work with legend.
If i shall not find a suitable solution here. I will be left with no choice but to spend more money. Try ScanDisk.

Anyone??? I dont want to end up buying another card just to find out it doesnt work either.

man i have the same issue using kinsgton 8gb microsd hc, for example i do some photos, and on the 5th one, it says unaable to save file do unsuitable permissions or smth like that...it also mixes my music in a way i cannot imagine ! ahah, it puts like..5 songs into 1 without any pause ...dont know. the stock one is perfect, but i just guess theres problem with the company..they might be fake.

Try to enable usb debugging mode.

You should consider that your card is a fake one ...

That could be the case. At this point i have given up trying to make 8gb card work on my phone .I think i will buy ScanDisk and give it a try.
Any idea how much write speed a class 5 card should have?

Class 5 has minimum write speed of 5MB/s

5MB/s minimum. If class 5 existed
Here is the definition of the class for sdcards :
Class 2 : 2 MB/s minimum write speed
Class 4 : 4 MB/s minimum write speed
Class 6 : 6 MB/s minimum write speed
Class 10 : 10 MB/s minimum write speed
However, certains class 6 are less performant than certain class 2, so try to choose your new card wisely.

sometimes it is not the brand but the shop/seller is the issue. can always buy online from Kingston online shop if u have doubt abt counterfeit.

Hi! Check the lock switch! maybe its turning on when you put the card into the phone...

I had kinsgton 8gb microsd with same problem
work fine on PC with low read/write rate and my HTC legend rejecting it sometimes saying i don't have permission over my SD
anyways, this was due to corrupted SD card. I replaced it and everything works fine now

I had kinsgton 8gb cls4 microsd with same problem
on my LG OPTIMUS ONE with froyo
it notify me with msg "SD card unexpectedly removed"
some time after this notify msg my phone reboot ifself

Copying SD Cards

I ordered a 32Gb SD Card for my HD2. But, I finally got a quality Android build going on my little 2 gigger. Everything works 99.9%. . . I did not think it was possible but after 2 days of tweaking and scowering threads I have one(I can share it if you like).
If I copy all files from my 2Gb card I can drop then straight on the 32Gb card after formatting.
Is there any issues with this at all?
I really hope not, since I have been working on this for pretty much two days straight.

You should be able to copy it over with out any issues. Just be sure to format your new card beforehand

I just got a class 4 Kingston 32gb microsd... I think that's the highest class 32gb available so far that's legitimate.
Anything that can read a 16gb card will be able to read a 32gb card... they're all sdhc. I don't think cards bigger than 32gb will be able to be made, though.

If you think logically, yeah ofc 32gb shouldnt be a problem O.O
well there is 64gb on his way to micro SD HC (2gb+ = HC -->High Capacity)
they're also making 2TB micro XC ( eXtended Capacity),, O.O
2TB!!! xD
my pc got 2TB, imagine 2tb in that micro sd,, WTF O.O!!!!
A lot of pron on the 4,3 inch big ass htc screen!! LMAO

Are they making a 64gb sdhc? I thought I read somewhere that 32gb was the limit for sdhc. I know sdxc will be able to hold huge amounts, but unfortunately our hd2s can't use sdxc. That would be great if 64gb sdhc is made, because eventually a micro-sdhc version will be made. 64gb storage for my hd2 would be awesome... I could keep my entire music collection in that, along with my ebook and comic book collection!

Dude as far as I know Kingston do not make a 32GB sd card yet so you have likely bought one of those cheap fake ones of somewhere like ebay from a Chinese seller that is actually only 4/8/16GB and will just corrupt most of data as soon as you get to the "real" size limit.
A lot of people have been fooled by these fake cheap cards (myself included in past)

Kingston does make a 32GB microSDHC card.

I wouldn't buy a memory card from eBay... especially not for a 32gb card. I bought it from newegg. And you should maybe do a quick Google search before claiming to know something, because Kingston made announcements about these class 4 32gb cards a couple months ago.

To expand on this (since I am still new to HD2 and Android), if I wanted to change SD Cards, or try out a new ROM, all I have to do is make sure the Android folder is copied over?
Example 1: New SD Card - Format new card, copy all files, will boot into current Android ROM.
Example 2: Same SD Card, want to try a new Android build, backup the Android folder, replace with new ROM and boot up, if I don't like it, delete new Android folder and replace with backed up one and will boot back into old Android build without issues?
Thanks,

Yes!
And same for kernel ( zImage if is compress, and ussualy it is ) inside Android folder

I did learn one thing the hard way. Doing this while booted into Android is not really a safe way to do it. When I backed up my Android folder and put a new one on, it would not boot back into Android (said no Android Build was found). Looked at my SD card on the device and in a PC and the space was used up (for both builds) but could not find them.
I ended up backing up my SD Card contents I COULDD see (pics and whatnot) and formatting the card.
I copied it on the SD Card via Adapter in PC and everything is fine now.
I would suggest (for safety), that you do it this way or from WMo.
Thanks,

Well, this is wonderfull. First SD card I ordered was from eGay. 13 Bucks for a 32Gb. Right after I bought it, the seller cancelled their eGay account and dissapered.
I bought another card now a 16 Gigger for 26 Bucks.
Seems to be fake. I copy over the info and then I can not read anything. . . .
Crap, should have spent the extra 10 Bucks. Now, I have to get my money back from GayPal.
eGay really does suck now. . . . .

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!

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.
