What Micro SD Card: Class & Brand

Looking forward to finally turning my phone into my day-to-day mp3 player, as well as running debian and apps2sd, I've been reading all the latest threads about sd cards and finally decided the most optimal config is a 16gb class 4.
Reasons:
· Class 6 is unnecessary as the nexus wont really take advantage of it.
· Class 2 may be kind of slow for apps2sd and debian, which I'm looking forward to investigate on.
· 16gb because although 32gb is comming, it will probably be too expensive for me.
Benchmarks:
I've looked through eBay and found a few interesting "offers", both at about $40:
SanDisk 16GB Class 2
TOPRAM 16GB Class 4
I really want a Class 4 for all I've been reading lately, but I can't afford a 16GB Class 4 SanDisk.
Does anyone know anything about "TOPRAM"? I had never heard about it before and I'm wondering if it could be a low-quality card.
Any help will be greatly appreciated.

No one knows ANYTHING about TOPRAM?

I've seen ppl complaining on the internet about the device not recognizing the sd card, but i guess that happens sometimes..i think..o.o

I have always used A-Data cards, been happy with them.
here are some speed test people have done http://wiki.cyanogenmod.com/index.php/SDCardSpeedTests

I use and trust PNY class 4 sd cards never failed a year in my rooted g1 and still going with apps2sd and so far with my nexus

With all the talk about SD card speeds I've been seeing lately, I was starting to regret buying the SanDisk 16gb class 2 and not getting a Class 6. But after looking at this chart, I can't imagine why I would need more speeds than that?

I have a 16GB Team Class 6 from ebay

I'm using a Polaroid 16gb class 2. Seems to be working fine for me, even running apps2sd.

I have an 8gb class 6 from RiData. seems fine to me, used on my MT3G, HD2 and now my N1.
i do agree with you though that a 16gb class 4 might just be the best cost/performance

Since we are talking about storage memory, I have a slightly unrelated question. Which is the better, microSD or internal storage that comes with some of the phones out there? In terms of speed, reliability, and cost, which one is better?

With regard to Class 6 - don't write it off if you plan to remove the card from the phone to do movie or music transfers. There are a lot of microSD adapters for computers that can exceed the performance of a Class 6 card and so if you are commonly hooking it up to a computer to transfer media then you'll be glad you went with a Class 6.
Now, if the capacity gets high enough to store all of my music, then I won't care about that issue, but personally I can only store a subset of my music on my microSD card so I do worry about the speed when attaching it to a computer...

i have that TOPRAM sd card on my nexus one i got from amazon Usa and it work very well

Class2 is definitely slower
I've used classes 2, 4 and 6 in an HTC Magic. I used apps2sd with Cyanogen Mod.
My own experience was that Class2 was definitely slower when using apps2sd. But Class4 and Class6 were better...and didn't appear to be much different. I had Class6 sdcards anyway as that is what was recommended for most of a year. They performed well.
The last ones I bought were Class 6 8GB Transcend MicroSDs for NZ$40 each (US$28-ish). That included 12.5% GST.

Compatible SD Cards for Windows Phone 7

Hi there,
i want to make some Thread about the SD Cards for the use of Windows Phone 7 and want to collect information. I Think many people who want to use WP7 on HD2 have to buy a new one, even my 16 GB SanDisk Class 6 is not compatible.
I found this on web:
Hi, actually the Samsung Focus has a 16GB internal memory and expandable up to 32GB. So you can insert a 32GB micro SD card on this device. However there are certain limitations when it comes to the micro SD card. Compatible micro SD cards will be branded as “Windows Phone 7 Compatible” on the packaging. Approved cards can be obtained from the manufacturer or carrier. (The SanDisk 8GB class 2 micro SD card has been certified.) Many commercially available retail micro SD cards are not approved for use in Windows Phone 7. Use of unapproved cards may cause performance degradation or device instability, including unexpected reset and loss of user data.

edit: ah sry i think wrong section

i use a 32gb SDHC sandisk (don't know the class but i think this is the regular one...)

For WP7 i use the 2GB SanDisc that was sold with the phone. I had crashs at first install but after Hardreset it is working without lags or crashes. Everything is fine.

but so far i know only class 2 sd's from sandisk are working

I have a sandisk 4gb class 4, everything works normally from the first boot
Sent from my HTC HD2 using XDA App

My 16GB Sandisk class 2 worked then all of a sudden the phone kept rebooting constantly. I had to reflash again to fix the reboot, 1 hour later it kept screwing up again.

i have wifi problems with my sandisc 2 gb , today i will be tryin lixar on 16gb

I also tried the 2GB SD Card, that came with the phone. It doesn't work. The phone shows only 15mb and the free space is full after a few minutes using it.

Yea, phone memory is VERY low but i copied 1,5gb music on my phone with that ****ty zune software and i can play it with the music player on wp7. Looks like the card is in use but only a low ammount for the system i think.

My Kingston 4GB Micro SDHC class 4 works but I'm finding that the Phone can get very laggy. I didn't have this problem when there was no SD card in the phone. I'm guessing its my SD card?
Can everyone post how the phone runs with their SD cards.

My 8GB Class 4 Kingston (SDC4/8GB) work like a charm :>

Hi bro, cheers for that information. Checked the sources you provided. Interesting comments there, one saying that SanDisk withdrew its compatibility Page since they haven't tested their (those) cards on WP7 yet themselves...
So we actually are left out in the wild with as much info as before. So it is even more important that people here report their experience with their cards.
I would strongly recommend, that people pay very close attention to the performance and any interesting detail before they post reports here. This would ensure quality of this thread is high. Maybe you, the OP could add cards, that have been verified by more than one user as working well to the first post? May i suggest that?
cheers...

Kingston 8 GB class 4 SDHC working fine on WP7

Class 4 Sandisk 8GB, works amazingly!, first flash, of course i hard reset it when it was flashed as per win-mo days

Was using Kingston 8gb class 4. Phone picks up the card fine but I was seeing random lags throughout system . It also slowed the market place down to where it was dreadful to download an app. When I removed card. The system is incredibly speedy, and shutdown speeds are very quick.
I am not sure if this is a general problem with these cards but I am going to send mine into Kingston for a replacement, I've read some reviews that there quality control has been hit and miss and some cards don't operate at rated speed.

32gb card problem !!

I need to use w7. Class4 32gb card is available. How can I use this card in w7, or can I use without any problem which I use with rum. I tried the reset at startup which puts rum always opens by chance, but after seeing this at a time card but gets stuck constantly scratching his rum. Is there a solution or stable rom 32gb class 4 card, which runs with the idea here?
I did my English is not good sorry for that translation google translate

you can try every rom
but its not the rom but your card that is laggy
not every card is good for wp7 so your have to change your card

I'm sorry English is not very good .. Do you have a rom that will support my card now, but I find it needed? previously or currently using a 32gb card and wonder if you have friends among you?

nothing to do with the size, 32GB is the maximum our hardware is capable of taking, buying a 32GB card for our device in the HOPE that it works seems a bit mental to me, yours doesnt work by the sound of it, but that is not because of the size, some of us believe its to do with random access speeds, class 2 or 4 is usually a good bet but by no means will they give you a 100% chance of it working.

Both my Sandisk 32gb cards have worked fine for me... 1 is class 2 with part number ending in A11M, the other is class 4 ending in P36A. Sandisk is a good brand and are pretty consistent in their cards, but even so, there's no 100% certainty that getting the same card will have the same exact performance... but I believe Sandisk gives you the best chance of working well.
I have also tried with my Kingston class 4 32gb card, but that card didn't work too well... was laggy, and kept resetting and not reading the card after reset.
What brand of SD card are you using?

integral micro sd hc 32gb class 4

[Q] Best 16Gb SD card for HD2 with WP7?

Which is the best 16Gb SD card for HD2 with WP7 (no freezes, no reboots)? And which card installed in HD7? Thanks!

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.

I use the stock sandisk 16gb, class 2 sd card that came with my phone. Runs smooth as butter!

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.

My hd2 wp7 doesn't read my 16 gb sandisk class 2 at all. How do I get it to work?

I first used a Kingston 16gb class 6 but had constant freezes, laggy os and constant reboots. Than I used the SanDisk 16gb class 2 and the phone runs just as smooth as my brothers hd7. But I do get occasional reboots still...

A-data microSD 16Gb class 6 work on my HD2 with Wp7 2 month without problems

i have Sandisk 16GB class 2

I have an SanDisk 16gb Class 4 and after First Boot nothing happens.
Without SD Card wp7 Starts und run perfectly...

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.

A list of micro SD(HC) cards supported by HTC HD2 for Android?

And I don't mean for installing a ROM onto (I use NAND builds)--just for storage purposes.
Been looking at upgrading my slow 8GB storage card to a faster and larger one (16 or 32GB), and I can't seem to find what is going to be compatible and what will not. For example, I was going to get a 16GB PNY Class 10 card, but one of the first user review comments was that someone got one for their rooted HTC HD2, and the card would not allow the phone to boot (however, it worked fine with their camera).
I'm not sure if I should go with SanDisk cards or Samsung cards, or PNY, Class 6 maximum, Class 10 maximum, or what have you. Some are on better deals than others, but clearly price is secondary to compatibility.
Is there some sort of a master list of compatible cards that I've missed in my search? Many thanks!!!

Thank you. I do respect Samsung a lot, based on personal experience with desktop RAM, but my brief research into Sandisk offerings have returned questionable results: some people say that advertised speeds don't match real transfer speeds.
What about the PNY cards though--I'm still unclear what makes a card compatible or not. Is it down to individual firmware or is there just some basic limits for HTC HD2 Leo (rooted) -- like no UHS cards. In theory, those PNY Class 10 cards seem like they should be okay, but that one review makes me wonder if the user did something incorrectly, or whether there was a true incompatibility.

Been looking at Samsung cards, and they come in a few varieties: regular, "plus", and "pro". The first two are older, I guess, since they are stamped with "class 6" but differ in their speeds.
The "regular" version for up to 24MB/s:
http://www.samsung.com/us/computer/memory-storage/MB-MSAGB/AM
The "plus" version with "UHS-I Interface" for up to 48MB/s:
http://www.samsung.com/us/computer/memory-storage/MB-MPAGB/AM
And then there's one labeled "class 10" that is the "pro" version, supporting up to 70MB/s:
http://www.samsung.com/us/computer/memory-storage/MB-MGAGB/AM
I imagine the regular version is just fine, but would the faster two cards simply not work with HD2? PNY Class 10 cards are better priced, but again, I have no idea if they will work. Any pointers into how I can research micro SDHC card compatibility would be greatly appreciated! The manual and phone description simply state that it is SD 2.0 compatible up to 32GB, which doesn't help with my search, since some of those cards appear to not work well (hearsay).
