The thing is , first most important part about SSDs is minimizing the writes to the disk, which is why people add
noatime to the
Second , is running
TRIM which reclaims unused blocks of NAND memory back to SSD. Windows has TRIM enabled by default, AFAIK, so no one bothers there. With Ubuntu, it does have a weekly cronjob for TRIM, however for I've learned from Rinzwind's answer that the cron job only runs on Intel and Samsung SSDs. That's why you have to edit that
/etc/cron.weekly/fstrim file to have
exec fstrim-all --no-model-check line, so that it runs no matter what is your SSD model.
Over the recent years, this has not changed - these are still key points , minimizing writes and enabling TRIM.
Removing writes and expensive storage amount is the two factors why people also remove swap area. By default, Ubuntu creates swap partition equal to your RAM size. I have a 128 SSD and 6 GB of RAM. That means that by default Ubuntu will chop off 6 GB from 128GB, leaving 122GB for my OS, and 5% is typically reserved for root, so that leaves me 122-122*0.05=115.9 GB for myself. I might as well use that storage for something else, which is why I have only one main partition, no swap partition, but I do have a 512 MB swap file as a protective feature (not that I plan on running out of RAM, but it's always recommended to have swap)
