Hi all!
What memorycard is to prefer?
I know it is microSD, but there's so many different microSD's out there so how will I know which one to choose? (classes, speed a.s.o.)
If we don't care about memory size (4-8-16GB) what is the very best to use?
Best memory?
Best memory/$?
What memory NOT to use?
I picked up an A-DATA 8gb Class 6 microsd card (US$35) to use once I get the Touch Pro. I haven't used it yet, but I also have the 4gb version (US$15) which works great.

DO NOT BUY.
That's SDHC, not MicroSDHC...
32 gig Micros aren't available yet.
This is a totally personal opinion. You will find that among us professional geeks, we have brand preference.
When It comes to Solid State Media, I always pay a little more the get a SanDisk item from a reputable dealer.
Every Card CF or SD or my MicroSD, has been SanDisk Manufactured and I've never been disappointed.

OK guys, thx for your input!
@JimmyMcGee: Yeah, I too has allways payed a little extra when choosing between some things, in most cases it's clearly that you get what you payed for, I mean, even if you look beyond brand names a.s.o. there often is a difference between the cheap and the more expensive ones.
But my reson for this Q was foremost to clarify the speed and class issue, is someone better then the other, so except brand, what more do I need to consider?
I bought a Scandisk 8gb. Play.com have them for £16.99 with free delivery.
I found this after i ordered the same from mobymemory which was more expensive.
I am also looking for a microSD card for my future friend Raphael.
I want the fastest 8 GB MicroSD card available that can be used in Raphael. €10 more or less, I dont care but I dont want to pay for overkilling the spec.
What MicroSD do you recommend, if not this one that I have found:
SanDisk Mobile Ultra 8GB microSDHC
http://www.i4u.com/full-review-447.html
Would it work fine in a Raphael?
Have anyone used it in an other HTC?
Simple:
Dont buy a memory that don't have "C" logo with class number in it.
If it doesn' have it, there's probably nothing to be proud of.
Currently you can get a decent-prized "class 6" memory with 4 GB or 8 GB capacity.
Class 6 is faster than Class 2 and Class 4 of course.
Cheers,
bought a sandisk 8gb microsd sdhc card .. 7700 mb free
they sell it at mediamarkt for 40€
@corsa2: this is probably the same card it is pretty fast and works fine as these are designed for mobile phones
Just buy a SanDisk. Work out how much memory you are likely to need - get a card with more than you require and MAKE SURE ITS A SANDISK! this will avoid fighting for refunds, hours trying to reformat, burnt dinners cause you are engrossed in the problem, angry women who just don’t understand why you don’t pay them any attention anymore, females who fight back when you loose you temper cause your new "good value" f'n card has failed and you refuse to accept the fact - BUY A SANDISK... I don’t work for SanDisk but they do work for me and will probably work for you…
Just bought a Touch Pro... will update my sig when I've decided which ROM to install...
Rgs,

SanDisk Mobile Ultra 8GB is superb!
Bought this one for my MDA Vario IV (T-Mobile branded HTC Touch Pro) for 40 euro at the Phone House (Netherlands). This class 6 micro SDHC was 10 euro more expensive than a class 4 device, but worth every cent!!
I've used several brands micro SDHC cards, but i'll stick to SanDisk now, maybe more expensive but reliable: no issues at all for about 3 years of use in my PPC's.
I don't have a Touch Pro yet (that will change in around 3-4 days though), but I do have a Sandisk 8 Gb class 4 card, which is very good but unfortunately isn't sold anymore, now there's only class 2 and 6 (which is extremely expensive).
I tested it with H2testw and got the following results:
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 11.4 MByte/s
Reading speed: 16.8 MByte/s
H2testw v1.4
I was wondering if anyone with a class 6 card could do the same test?
Hello there, just bought a PNY Micro SDHC Premium 8 Go ... but it's not recognize by the phone ... do you think that it can be solve by a Rom update ?

There are a number of dependable cards out there. Amazon has user feedback on each of their cards which can be useful to help you decide which card is best for you. Which ever card you chose, make sure you format it before you use it. Put the card into a card reader and format it FAT32 on your computer at least once. The ROM should not be a factor in you device reading your card, FORMAT the card...David.
Ok thx for the information
Formating was the first thing I did after trying it in the phone ... but didn't help
I bought the PNY because It's suppose to be a good brand, and never thought it would not work with my phone
Guess I gona have to buy an other one
Thx
I bought a 16gb Toshiba MicroSDHC card yesterday for $50. So far so good--I put it in and it has been working flawlessly. Hope I'm not jinxing myself! lol
IMHO I don't think it really matters but I have always used Sandisk and have been quite happy.....
i use a-data since i find it to be the cheapest. i've used 4 and still use them. no data loss or failure yet. oh and i just ordered another just for my fuze. 8gb ($18 shipped)

Hey guys, I tried to search about this topic in the forum but I don'y anything about it or was it just already in pit of the forum?
Anyways, I would like to ask the maximum capacity of memory card for Elf(in)? I am planning to buy a micro-sd and I just want to buy the best available.
Does it support SDHC memory cards? And also, does using a large GB of memory presents a risk on my device to be brick when time goes on?
Thanks for the help guys!

I have 4gb micro sdhc and it works fine. I have heard that 8GB won't function properly after a while. But I am not a genius
SanDisk 8GB
I've been working with a SanDisk 8GB MicroSD HC for about 4 months now, and still have had no issues...
And that goes without saying that I think It's a fake SanDisk, because of the packaging.
Have an 8GB SanDisk on my Elfin. Works great.
@vette95: Good to hear that! Thanks for responding..
@htedum: how long have you bean using your 8gb micro-sd? Haven't experienced any problem yet? Any slow down or hangs?
i've been using 8gb in my elf for over a year and did not ever have any issues or hangs so i would recommend it.
just my 2 cents
Wow! Thanks bro for the feedback! Will buy 8gb now.. hehe..
Been using it for two weeks now; no problems at all. I've overclocked to 273 using HomeScreen, maybe that helps. Loaded up 6G worth of music and 1G worth of movies. Installed PocketPlayer (and TCPMP for movies), and I have a slick, portable media player. Battery life isn't bad at all, but I've ordered a 2500mAh replacement, waiting for that to come in.
A tip - be sure to pick up an original, name-brand card, even if you have to pay more. A lot of fakes going around, they may slow down your phone.
@vette95: No problems with your fake?
I've been searching google how to detect fake micro-sd but unfortunately the only info I got was to make sure the serial of the memory is readable and also try to call on the manufacturer and confirm the serial. Of course, I cannot do that when I am in the store, to check each items and call them. LOL. So do you know other ways how to know it if it is genuine?
The best bet would be to avoid ebay and the like; that's where most of them are floating around. Since you're buying retail, you should be pretty safe, since you can go right back to the store if you discover that it's fake.
From what I've read, there's also the issue of classes; best pick up class 6 or at least class 4. Class 2 will be slow.

Also check the packaging. Check if the fonts are printed alright and not fading or anything.
I have already bought a 4gb sdhc class 6 kingston micro-sd. There is no 8gb available in store so I decided to just go with 4gb and just upgrade when I need it. It was fast and I guest it is not fake(though I'm not sure). Thanks for the advice guys. I hope this will also be helpful for people who are planning to upgrade memory.
As far as I know, Transcend and Sandisk are the brands that are flooding in the market which are fake so I really looked for other brand. Fortunately I found one and it is made in Japan(the fakes are made in China written at the back of this brands) so I'm little confident with the memory I bought. hehe..
ive been using an 8gb card too for awhile now on my elfin. just got my 16gb card last month and havent had a problem yet. everything runs very smoothly.
i have 8GB V-gen and running well until now...
8gb
i´ve used a 8gb sdhc since a month without problems...it runs smoothly...
I bought a 16 gb sandisk sdhc. It didn't even register regardless of what drivers I installed on my phone.
I've just experienced a weird issue with the SD cards.
So whats happen.
After I started to use Android on my HD2 my 8GB Kingston Class4 SD card just get a bit small. So I decided to buy some bigger one. First I bought a 32GB unbranded micro SD but soon I found that HD won't take that much so I sold it straight away.
Than I've looked around here on XDA and I found that so many guys using 16GB without probs.
So I bought another SD this time 16GB unbranded ( to keep the cost low) Class10 what's probably fastest at the moment.
I backup my old 8GB card ( just copy all content into my comp ). Than copied all content onto new 16GB card and sticked it into HD2. I thought all should work without any probs but it wasn't.
Phone was really slow, unresponsive, many fc.
OK I set its just need to flash the ROM again so I deleted content of .data folder and did a fresh clean flash with all caches wiped. I thought after this it have to be OK but again it wasn't.
So I started to be a bit worried by that time than I decide to buy another 16GB card but this time I spend more and I bought a Kingston 16GB Class4 ( same brand and class like my old 8GB ). That was for sure it will work 100% if my old works fine. And many people using 16GB, also one of my friends got 16GB SanDisk with Jaws MIUI ( I flashed it for him ).
So today I received that new 16GB Kingston Class4.
I did the same again - backup/restore all content and surprise *** NOT GOOD again; slow, unresponsive, fc's
So reinstall again and surprise *** NOT GOOD again; slow, unresponsive, fc's
I've almost rip of all mine hair (I mean the few bits whats still there )
So after all of this I came out with the last chance idea....
To do total wipe - thats included
- delete all data from the card
- flash stock Winmo ROM
- flash latest MAGLDR
- flash latest CWM Rec.
- flash latest Jaws MIUI
.......
.......and surprise *** All is OK, the SD is working just fine, finaly
So weird and I don't understand this.
I know this was probably long reading post but maybe someone have an explanation for this or some one have a same issue like me and can use this like a last help.
Where did you buy the card from? The market is flooded with low quality counterfeits, so always buy good brand from reputable source. I always buy sandisk, and never had a problem.
well normally I buy a Kingston or Sandisk. This was a first time I get unbranded cards but anyway at the and it wasnt caused by card quality cos this Kingston didn't work, only after I've done all that steps all is OK.

I have the same issue with Kingston 8GB Class 4 SD card, it is very slow, unresponsive and sometimes it doesn't come back from lock screen... i have to restart it... right now i am using Scandisk 4GB Class 2 card, it is OK but my phone heats up pretty quickly...
How can i resolve the heating issue... any idea?
Well, Kingston re-brands their SD Cards, so you never know what you're getting. I have a few and you can just pull the "Kingston" labels off to see what the original manufacturer is, and often thats just another rebrand anyway. I'll assume they do the same with their Micro SD cards.
maybe its a fake card
If u want to verify your card genuine or not, go to fake-memory.com,
u can download some tools over there.
your card might be ok today, but once its near full, you will see weird thing happening again, I also bought OEM card. (unbranded)
lucky my "32GB" is really a 1GB, so I spot it early.
Just get refund from seller through ebay.
I would have think about the SD also. But due to the solution you apply, I think now about a corrupted file somewhere. Maybe at a low level of your NAND.
That's just a thought (so maybe not so helpfull).
We play sorcerers with our phone... so I'm not surprized this happens.
I also have a corrupted SD few times. The validation processes are important and I don't think we can do the same as manufacturer on this point.
As the first level loader is never touch we can't brick our phones but this is the price to pay. DO NOT PUT VITAL DATA WITHOUT BACKUP IN YOUR PHONE !

What I meant was where did you buy your kingston from? Kingston cards counterfeited alot. Kingston is also known to sell many low quality or defective cards. Kingston doesn't do any of their own manufacturing... they just rebrand cards, so many times they get bottom of the barrel cards. I won't buy kingston anymore after I did some research. Sandisk actually owns their own factories and create the chips they sell... they probably keep all the good ones for themselves and sell the bad quality or defective ones to kingston. I really don't understand how kingston is known as a good brand-name, because they shouldn't be. Buy sandisk cards from a reputable seller.
I got 3 micro cards
1. adata 16gb class 10
2. pqi 8gb class 6
3. sandisk 8gb class 2
All cards are without any errors and works with WM6 well. Unfortunatelu on Android with ext partition isnt so good.
There is no single rom using ext partition and working well on my class 10 card!!!
On PQI some works ok, some not
And on Sandisk every rum is running without errors.
What's going on? Ported android to HD2 probably is not 100% compatible with HD2 card reader ;-((((
I thought all is OK.well it was a day and now im back to sh*t.phone its slowing down,sometime cant wake up from lock screen or have to wait 30 or more seconds. i dont know whats the problem. looks like i have to sell my card and buy another one.this time i go for Sandisk but 100% genuine. its gona be expensive but what else i can do :-(

Maybe you have tried before...
Why don't you try another build before buying another SD? This at least will cost nothing. Just to be sure.
it seems we're all agree to say that Kingston sucks...
cheers.
I've already tried and its same. Its definitely a card issue.
Damn, I have to buy another one, 4th card in week or twoo
will see, hope die last...

Goodnight/Good morning my fellow XDA-ers!
Okay so I have a USA T-Mobile HD2 I installed WP7 the day after it was released by DFT but the day after I was forced back to WM6.5 due to the SD card issue, my device was constantly restarting every 15-ish minutes. I was wondering if anyone has any experience running WP7 successfully on their HD2's for a decent amount of time with a specific card. I'm willing to purchase one of these cards as I want to get away from WM6 as soon as possible, but I really want to know if the card will work!
What I'm looking for is a 16Gb card that works. So if you have purchased a 16GB micro SD card that has been working flawlessly with your HD2 for some time now, please chime in, and please include a serial number as I want to get the exact thing!
Thanks for your time.

Just recently purchased a Sandisk 16gb card. Works flawlessly. No crashes, hangs, resets or whatsoever.
AAARRRGGHHH!!!!
how many times do a few others and myself have to tell people this!!!
no two cards are alike, you could buy two identical cards and one might not work, there is no "working card list"
Statistically you will have better luck with a class 2 or a class 4, ive personally had better luck with sandisk class 4
but that is it, its just luck
I've been running mine flawlessly since the first rom (now on my second) on my HD2. I'm using the stock 16gb SanDisk that came with the phone. Indeed it is "luck of the draw" but most people I've talked with and/or flashed for others have had no problems with the stock sd cards.

I like you had the same problems with a few SD cards. I remembered seeing a post going back about Sandisk selling SD cards as being HD compatible. So I did a search and found the cards and their model numbers, bought one and have had no problems at all, no lag and WP7 runs perfectly!

Yeah, the class 2 sandisk with serial ending in A11M were called wp7 certified by sandisk for about a day before they pulled that certification. What dazza said is true... at the moment, card makers don't test their random access speeds and don't keep them consistent enough batch to batch to guarantee any specific card will work. Sandisk makes very high quality cards and I think you're best chance of getting a card that works is to go with class 2 or 4 sandisk. I have few Sandisk class 2 cards ending in A11M... 1 8gb, 2 16gb, and 1 32gb. All work... All work flawlessly except for 1 of the 16gb cards, which give a little lag, but no resets or anything like that. After testing, the access speeds are very different on the 2 cards, even though they are the same brand,class, and model number. Were even bought from same store, but 6-9 months apart.
So yeah, if you want to try wp7, go for a class 2 or 4 sandisk. It will most likely work... but there's no 100% guarantee. But sandisk has good warrantee... if in the rare case it doesn't work, tell sandisk it's brok or something and try to get them to send a different one.

You may get varying answers with that question but I was using the Sandisk Class 2 16gb card that came with my TMOUS HD2
I ordered a class 2 San disk off Amazon.co.uk for 15.99 I ended up with a class 4 one off them and it works great but I also heard its pritty much a lucky dip with sd cards for wp7.
no way of knowing what cards will work unless you try it, that is the only answer im afraid, class 2 and 4 seem to have a higher chance of working but your just as likely to have a sandisk working as you are having a supermarket own brand
course the flip side is you may get a class 6 or even a 10 working fine too...
its luck, good luck!
Just thought id add my 2 pence, I started with an 8gb class 4 card (brandless) and decided I wanted more memory so I bought a San disk mobile ultra 16gb class 4 from eBay. I was happy with my 8gb cards performance until I replaced it, the speed increase was massive so I would recommend the mobile ultra by San disk my self I picked mine up for £15 with free delivery

a working OS has absolutely no lag, it smooth and very slick, there is a slight touch screen bug that may mean you need to swipe a couple of times but actual OS transitions are incredible, so if you dont have the experience i have mentioned then its likely your card isnt 100% compatible.

The os was slick and smooth on my unbranded card, the speed difference i noticed was when it came to installing apps. I would estimate it takes a quarter of the time to install an app than it did before. Also there was an increase in speed in running some apps for example fruit ninja used to be slow in parts and now runs alot better

oh for god sake, here we go again,
ITS LUCK!! there is no relation to any SD card working on the HD2 for WP7 other than class 2 or 4 seem to have a high chance of success, thats not to say class 6 and 10 wont work, just less likely
Sandisk have cards that work and others that dont, they are not above this problem, two identical cards may not work the same, because the manufacturing process isnt always the same.
in short, ITS LUCK!!
lol
Unless they start advertising it as a WP7 compatible card, which i doubt will happen as devices that run WP7 must have the SD card in or use additional NAND memory, given that mainstream joe public isnt likely to break down their £400 phone to add some memory i doubt very much that SD card manufactures will release a branded product to the highstreet specifically designed for the WP7 devices that can ripped apart to allow an upgrade to the internal SD card.
the very best you can do is find out the batch number of some of the SD cards in the HD7 and attempt to find a high street version sporting teh same number, good luck with that.

Today I changed my 16GB SD card from a no-name class "I don´t know" to a 16GB class 10 SD card. The Phone ist now much more faster than before, it is nearly as fast as my HTC Mozart.
When you have probs with the SD card, it was a very good hint to format it with the digicam.
