<\/span><\/p>\nWhen you\u2019re freshly installing a Linux system, it\u2019s best to use the ext4 filesystem. It\u2019s the most used, and most stable, filesystem available that supports TRIM (which still needs to be enabled \u2013 more on that below).<\/p>\n
<\/p>\n
This shouldn\u2019t be much of a problem: most distributions default to ext4.<\/p>\n
Mount Options At Boot<\/h2>\n
Every time you boot your Linux system, it must mount the various drives in your computer in order to use them. There are various mount options you can use, depending on your hardware and your needs, and some are appropriate to use with SSDs.<\/p>\n <\/p>\n To make these changes, open up your terminal and run the command\u00a0 Then, add the following mount options:\u00a0 If you find that some programs are misbehaving with the noatime option (as last accessed times will be before last modified times, which is normally impossible), you can replace noatime with relatime. This updates the last accessed time with the same value as the last modified time, all in the same write operation.<\/p>\n When using an SSD, it\u2019s also a very good idea to not have\u00a0a SWAP partition\u00a0on it (unless you have a serious reason to do so).<\/p>\n <\/p>\n The constant reads and writes SWAP partitions do add significant wear-and-tear to the SSD. If you really would like to have a SWAP partition, it\u2019d be better to place it on a secondary, non-SSD hard drive if at all possible. I know it\u2019s tempting to put a SWAP partition on an SSD \u2013 it would be the best-performing SWAP partition you\u2019ll ever have \u2013 but this speed comes at a major cost.<\/p>\n A lot of people suggest that you can still add a SWAP partition but disable hibernation, since that causes extreme amounts of reads and writes. But since it\u2019s rare that you\u2019ll use a SWAP partition, as you probably have more than enough RAM, it\u2019ll just take up space and potentially cause wear-and-tear. Also, not including a SWAP partition to begin with is an easy way to disable hibernation.<\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Get the most out of your SSD in Linux \u2013 here\u2019s what you need to know.

<\/span><\/p>\nsudo nano \/etc\/fstab<\/code>. Next, find the partition(s) in your SSD(s) that are listed in this file. Partitions here are normally listed by UUID, which is more precise than the\u00a0\/dev\/sdXY<\/code>\u00a0identification system. If you have multiple partitions, you can use the command\u00a0blkid \/dev\/sdXY<\/code>\u00a0to find the UUID, replacing X with a-z and Y with 1-9.<\/p>\ndiscard<\/code>\u00a0and\u00a0noatime<\/code>. Discard allows the SSD\u2019s TRIM function to be used \u2013 this improves performance and longevity. The other option, noatime, tells the filesystem to not keep track of last accessed times \u2013 just last modified times. This can reduce wear and tear on your SSD, because there are many files that you access while you use your computer but there are far fewer files that you\u2019ll end up modifying. The file should look similar to the screenshot above.<\/p>\nDon\u2019t Use SWAP<\/h2>\n
