Compatible SD Cards for Windows Phone 7

[romskii]

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.

So first SD Card witch is compatible is the SanDisk 8GB class 2 micro SD card

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.

you sure? i also had insert my 2 GB after the 16 GB makes crashes...but i think it's still not included in system, because i only git 180 MB storage i'll try out at home with the offcial post of WP7 ROM

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 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.

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

 

[Jonny4911]

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.
