[Funtoo Stable Desktop] Optimization of mount options for ssd.

Question

Hi Dear Friends.

I've 2 disks.

 

1) The first is an SSD of 120 GiB; I've installed /boot , swap and the root partition.

2) The 2nd is an classiic HDD 1TiB.

 

I've used ext4 for /boot anx xfs for root and /home

This is my actually fstab:

 
ci74771ht ~ # cat /etc/fstab 
# /etc/fstab: static file system information.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#
# See the manpage fstab(5) for more information.
#
# <fs>                  <mountpoint>    <type>          <opts>          <dump/pass>
 
/dev/sda3               /boot           ext4            noauto,noatime  1 2
/dev/sda5               none            swap            sw              0 0
/dev/sda6               /               xfs             noatime         0 1
/dev/sdb2               /home           xfs             noatime         1 2
/dev/sdb1               /mnt/Volume     ntfs-3g         defaults        0 0
#/dev/cdrom             /mnt/cdrom      auto            noauto,ro       0 0
shm                     /dev/shm        tmpfs           exec,rw         0 0

I'd like to hear your opinion about it and if I can add options to henance performances about my ssd ....... especially about security and stability.

Hi, when researching about SSD, I found this helpful link:

http://blog.neutrino.es/2013/howto-properly-activate-trim-for-your-ssd-on-linux-fstrim-lvm-and-dmcrypt/

 

Also relevant:

http://wiki.gentoo.org/wiki/SSD

https://wiki.debian.org/SSDOptimization

 

In the end, I have just "noatime" in the fstab and I do "fstrim -av" when I remember.

Thanks for your answer dear emarsk.

For Now i've operated only at cron level:

 

i74771ht ~ # crontab -l
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/home/sandro/Funtoo/crons.cron installed on Sun Dec 21 22:10:02 2014)
# (Cron version V5.0 -- $Id: crontab.c,v 1.12 2004/01/23 18:56:42 vixie Exp $)
*       *       *       1-12    1               /sbin/fstrim -v -a
