Ext4 filesystem hits Android, no need to fear data loss
Google's new Nexus S smartphone is the first Android device to use the Ext4 filesystem. The company published a statement on the official Android developer blog earlier this month to discuss how adoption of Ext4 on Android will impact third-party application developers.
In a follow-up post last week, Ext4 developer Ted T'so commented on the transition and offered some further clarification regarding concerns about fsync data loss issues, which he says pose minimal risk on Android due to the higher level of quality assurance testing.
An expert on filesystem development, T'so played a key role in developing Ext4, the current generation of the Linux kernel's standard filesystem. He was hired earlier this year by Google when the search giant was transitioning its server storage infrastructure from Ext2 to Ext4. He says that he didn't influence the decision to use Ext4 in Android, but provided some advice and guidance to the Android team after the decision was made.
