Fresh install on an SSD?

[SpecialEd]

I think I'm going to do a fresh install on a 500GB SSD (Samsung, 850 EVO). So far the most recent info I can find is here. Does anyone have recent experience with newer SSDs regarding over-provisioning, Trim, and Swap?

Also, most of what I have read/watched has pushed the idea of a separate /home folder, which I currently have. The above website recommends against that.

All suggestions and comments are welcome,

Best,

Having a separate /home partition is beneficial if it every becomes necessary to reinstall the primary OS, as you can do so and elect not to format the /home partition, keeping everything intact. You cannot do that if you do not have a separate /home partition.

Thanks for the always quick response Snowhog. I have a separate home folder now. If do a fresh install on a new SSD, will I be able to copy/restore a copy of my current home drive to the new install and expect everything to mesh? I'm thinking not.

While it's 'possible', it's more likely that there will be 'some' issues, although they'd likely be minor, not major.

Thanks again Snowhog. found some info here at this thread: https://www.kubuntuforums.net/showthread.php?t (funny, when I did a seardh on SSD or ssd, I got no returns, but when I did a search on partitions, I found this.)

Since you're doing a new install, consider btrfs as a file system. It supports trim and doesn't require partitioning for your home - it uses subvolumes. I and others have written about it extensively here and, as always, Arch maintains a good wiki on it.

As far as the SSD, common wisdom is to not use trim as a mount option as it's unnecessary and causes excess wear and drive usage. The preferred method is to "manually" run trim periodically. *buntus accomplish this through a weekly cron job, which I believe is the default. Personally, I think even weekly is too often for most users. Monthly or even less often makes more sense.

Also be aware that SSDs have come a long way in a very short time so most advice on the 'net is outdated regarding excessive wear and such. Modern SSDs like yours will likely outlast your need for it, so swap partitions are fine on an SSD. The one mount option I do always use is noatime.

Thanks oshunlluvr. That is one of my biggest concerns, the technology seems to be outpacing the tutorials. I've been reading the posts on btrfs but I'm afraid I don't understand it well enough at this point.
