SSD : reduce wear & tear
866/5000
What modifications should be made to reducing wear on SSD? I have read about "noatime" for example but did not get it EXACT how and
WHERE
you enter this in FSTAB! If it is wrong, the computer will not start o The entire installation is corrupt.
This is my current fstab:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass> /dev/mapper/mint--vg-root / ext4 rrors=remount-ro 0 1
# /boot was on /dev/sda1 during installation
UUID=437af9a5-5c9e-4a15-b07f-22640de64986 /boot ext2 defaults 0 2
/dev/mapper/mint--vg-swap_1 none swap sw 0 0



I used LVM2 when partitioning.


I'm not completely sure HOW I will mount the disks to access fstab if I would have to boot from a MINTSTICK o then try to edit fstab.

I am using an ssd on /dev/sda. I've had these options for a few years and it hasn't blown up or refused to mount. These are available within 5 minutes with google, and I'm only bothering to answer this because I need to rest for a bit.
Code:
bash-4.3$ cat /etc/fstab
/dev/sda3        /                ext4        noatime,diratime,discard         	1   1
/dev/sda2        swap             swap        noatime,diratime,discard         	0   1
/dev/sda6	 /media/hd0	  ext4	      noatime,diratime,discard         	0   0
/dev/sda1	 /boot            auto        noatime,diratime,discard  	1   2
/dev/sda5        /home            ext4        noatime,diratime,discard         	1   2
/dev/sda7	 /mnt/virtual     ext4        noatime,diratime,discard,user     1   2
/dev/sr0         /mnt/cdrom       auto        noauto,user,ro,comment=x-gvfs-show 0   0
/dev/mmcblk0p1    /mnt/zip	  vfat        noauto,relatime,diratime,user,exec,dev,suid,nofail     0   0
/dev/sdb1	 /mnt/hd	  auto	      relatime,diratime,user,exec,dev,suid,nofail     0   0
/dev/sdb2        /mnt/tmp         auto        relatime,diratime,user,exec,dev,suid,nofail     0   0
/dev/sdb3        /mnt/dvd         auto	      relatime,diratime,user,exec,dev,suid,nofail     0   0 
/dev/sdc1        /media/hd1       auto        relatime,diratime,user,exec,dev,suid,nofail     0   0
/dev/sdc2        /media/zip1      auto        relatime,diratime,user,exec,dev,suid,nofail     0   0
/dev/sdc3        /media/dvd1      auto        relatime,diratime,user,exec,dev,suid,nofail     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
tmpfs            /dev/shm         tmpfs       defaults         0   0
sdb & sdc are usb disks. BTW, mount really tries to mount stuff even if it gets stupid or incomprehensible options. It throws "you're a twit" type errors but you usually get going read only. You can remount even / rw with the sane options.
