Raspberry Pi 2 with 128GB microSD

Summary #

128GB microSD cards work with the Raspeberry Pi 2.

The Card #

The card in use is a 128GB Kingston SDC10G2/128GBFR

Check the file system ‘from factory’, which is exfat

ian@ian-laptop:~ $ blkid | grep mmcblk0p1
/dev/mmcblk0p1: UUID="0123-4567" TYPE="exfat"

Check the reported size, which is 118G

ian@ian-laptop:~ $ df -h | grep mmcblk
/dev/mmcblk0p1  118G   17M  117G   1%

ian@ian-laptop:~ $ df | grep mmcblk
/dev/mmcblk0p1 122691584     17024 122674560   1%

The Pi #

Raspberry Pi 2 Model B V1.1

Raspbian Jessie with a fully expanded filesystem.

pi@raspberrypi:~ $ df | grep root
/dev/root      120715332 925232 114856388   1% /

pi@raspberrypi:~ $ df -h | grep root
/dev/root       116G  904M  110G   1% /

Fill it up to confirm the full size is available for use (ie check the microsd card is not fake)

pi@raspberrypi:~ $ date; cat /dev/zero > /tmp/zeros; date
Tue Jun 21 22:02:27 UTC 2016
cat: write error: No space left on device
Wed Jun 22 00:34:29 UTC 2016

pi@raspberrypi:~ $ ls -hl /tmp | grep zeros
-rw-r--r-- 1 pi pi 110G Jun 22 00:34 zeros

pi@raspberrypi:~ $ df | grep root
/dev/root      120715332 115782080         0 100% /

pi@raspberrypi:~ $ df -h | grep root
/dev/root       116G  111G     0 100% /

The drive filled to 110G in 9122s for a write rate of 12.9 MB/s.

Conclusion #

Raspberry Pi can run with 128GB, as tested with the Raspberry Pi 2 Model B V1.1.
