SSD - best setup

Postby Ram » Thu Feb 20, 2014 12:59 pm

Just purchased SSD - what is the best way to set it up for use with Linux, trim etc.

Haven't decided where it going just yet.

Laptop - openSUSE 12.3 - thinking of upgrading to 13.*
Desktop - Ubuntu / LXDE 13.10.
Server - openSUSE 11.* - which does need an update.

I suppose the file system is up to you to choose, I use ext4, but I think btrfs is supposed to work fine with SSDs.
For mount options, I use noatime,discard and I've also moved some of the sections of the filesystem off to tmpfs to avoid unnecessary writes:
Code: Select all
#tmpfs modifications for SSD
tmpfs   /tmp   tmpfs   defaults,noatime,mode=1777   0   0
tmpfs   /var/spool   tmpfs   defaults,noatime,mode=1777   0   0
tmpfs   /var/tmp   tmpfs   defaults,noatime,mode=1777   0   0


I have found putting an SSD into a laptop disappointing on one machine. It seems, from what I have read, that the SATA bus is underclocked to reduce power consumption on some models (especially cheaper ones with smaller batteries).
However, on my desktop machine, boot to log-in is about 7 seconds and things like LibreOffice open in a trice.

I can test with the laptop first. HP G62 Quad core i3 so hopefully the sata bus hasn't been put on a go slow.

Is there any setup needed prior to installation of the distro?

Installing Mint16 (and 15 before it come to that) partitioning proceeded as with a normal HDD and I found the partitions to be aligned when I checked them (with parted IIRC).
The other modifications were made after the distro was installed.
