SSD

Problem: I bought a SSD
Solution: Read the corresponding section at the Arch linux wiki. So, I did:

• change in BIOS the controller driving the SSD to AHCI mode
• use gdisk to partition the disk (GPT)
• use EXT4 for filesystem
• do normal installation

After install edit /etc/fstab, adding the noatime and discard options to the EXT4 partitions: WARNING — read below!

EDIT (16 Jan 2016): Setting the noatime and especially the discard option may cause problems! Read this newer post!
