How not to wear out SSD or USB flash drives?

[Nexus7]

I'm trying to find out how to have the device notifier mount some partitions (other than root), and USB flash drives with noatime, so that they don't wear out fast. There seems to be no way to tell device notifier (the plasmoid that pops up from the right-bottom corner when you stick a USB drive in) to use specific mount options for specific devices.

I found some references to changing HAL settings, but those weren't recent. Also, around 2008-2009, there was an alternative version of the notifier called "devicenotifier_automount" that allowed setting mount options per device.

So how is it done these days?

Basically, FAT32 for USB sticks and either ext2, or ext4 with modified "commit-xx" values, for SSDs mounted in /etc/fstab. No need to fiddle with HAL.

Thanks, dibl. The links in your posting deal with disks that are mounted once at startup. I can't change /etc/fstab for USB keys that are plugged in and out, and also for partitions on the hard disk that I don't want mounted all the time. This is so because the Device Notifier mounts those.

If it is USB hotplugged storage devices, probably FAT32 filesystem is your best bet.
