And you almost certainly don't write to your SSD at 80M/s 24 hours a day. That is based on 2007 technology - SSD life will be longer now. In the article is a calculation of the life of an SSD that is receiving writes at a continuous rate of 80M/s.

In short the circuitry inside modern SSDs manages wear-levelling for you, and they know how to do it far better than you. You can read this detailed article about why you really shouldn't worry. Generally I wouldn't bother - the worries about SSD life are overblown. # none /var/cache unionfs dirs=/tmp:/var/cache=ro 0 0 #tmpfs /var/log/apt tmpfs defaults,noatime 0 0 #tmpfs /var/log tmpfs defaults,noatime,mode=0755 0 0 #tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0 #tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0 Open /etc/fstab with an editor (assuming you have backed up the /etc/fstab file) gksudo gedit /etc/fstabДЄdd the following lines at the end of the fstab file and save: # Uncomment these after all server based applications installed - eg.

Note: only make the following changes when you have installed all software you are going to use (especially things like Apache web server), otherwise you may experience some issues with missing directories in /var/logДЇor background to this approach, see prolonging the life of your flash drive on Therefore you can configure Ubuntu so all logs get written to RAM memory rather than the SSD. You will need to reboot your machine before these changes take effectДЈ) Minimising writes from the OS and applicationsДЄssuming that you are not running a mission critical product server, most people do not look at logs should something go wrong (especially as serious errors are rare for most Ubuntu users).

# /home was on /dev/sda3 during installation This decreases the life of the SSD.Д®dit your /etc/fstab configuration file (carefully - take a backup to be sure as breaking your fstab configuration can prevent you system from working): cp /etc/fstab ~/fstab-backupД®dit the mounting options for your partitions by adding the text noatime and nodiratime to the lines defining your root (/) and other partitions if you have them (/home) - Note: if you have a /home partition, start with that just changing that partition if you are concerned about breaking something # / was on /dev/sda2 during installation The reason this is generally a bad idea, is because every read will produce a write when updating the timestamps. These timestamp writes are not generally required unless you use a local mail server client such as mutt. Mounting your partitions with the options noatime and nodiratime will stop timestamp writes when you read files and folders. If you have a mix of SSD and hard drives, place your swap partition on the hard drives only.Дў) No Writes for Read Timestamps (suitable for SSD's and hard drives) If you do not hibernate your computer and you have ample RAM memory to run all your applications, then in theory you do not need a swap partition. I have successfully used several different techniques to improve the way Ubuntu uses the storage device, whether that be solid state or traditional drive.ДЇor SSD's you are looking to minimise the number of times the drive is written too, as reads should not add wear to the drive.
