Hi
I was wondering what the state of SSD support was. I upgraded a
netbook with a SSD and took the defaults from F14's live installable
USB disk's Anaconda.
The SSD comes unformatted, it's a OCZ Vertex 2E (SATA II) which
apparently has TRIM capability.
I wondered how I can tell if this hardware is being used to its full
potential, if the TRIM capability is being used and if the partitions
are aligned as they ought to be.
The output of sfdisk -l doesn't make it obvious if the disk is using
4k sectors or is aligned in any particular way. Googling reveals lots
of conflicting information... so any ideas?

PS. output of sfdisk -l:
