Hello all, I booted the laptop into a grml boot-cd, then checked things with hpdarm -I. It appeared this old SSD does not do TRIM. Given that it's just an old disk with possibly low firmware performance, and a small and cheap one anyway, and without TRIM, i decided to just go with the memory c

I think i meant GPT here. And from what i've read, following the link Bob Prolux posted, i conclude it doesn't really matter, as GPT is just a newer and more flexible system to cover disk sizes >2T, but for laptops the old MRB system should be good enough (as long as grub supports it). -- T
