I have a laptop (HP DM1-3100sa) and and SSD (OCZ Agility Series 3 60 GB) on order.
On my current laptop, I have a spinning HDD and use LVM and LUKS encryption.
I would like to use both LVM and LUKS on the SSD but from doing a bit of research I am not sure if this is desirable/possible.
It seems that LVM (most likely) and LUKS (possibly???) may prevent TRIM from working.
I can't find any concrete info on this and lots of the info on SSDs such as alignment etc seems to be out of date.
1) Is TRIM necessary?: The SSD has a SandForce 2281 controller. Will this provide adequate garbage collection without TRIM
2) If I need TRIM, will it work with LVM partitionis (I can live without LVM if needs be)
3) Will TRIM work with LUKS? Because a laptop may be prone to theft, I like to have my data properly encrypted so this is important to me
