SanDisk Ultra 32GB microSDHC & 64GB microSDXC Tests

If you are looking to make a bootable Android card for Nook devices, the SanDisk Ultra card will suffice. Both SanDisk Ultra 32 and 64 microSD cards have fast small block read and write even though the 32GB card fare a little better. 64GB card is formatted as exFAT and can be formatted as NTFS. As a warning, CyanogenMod or AOSP doesn’t support exFAT so your card will be damage if used. You’ll need recovery app to recovered lost data on computer or use “chkdsk X: /f” (Where X is the drive letter of your sdcard) in command window. You can use a partition app to format the card to FAT32 PRIMARY.

If you are looking to purchase the card for camera and other storages, you will be pleasant with its fast read and write speed.

Know that the values for read and write are not constant. The values below are ball park values to give you a good estimate of the read and write speeds.
