  • Will Ubuntu be the only OS on the drive? Your swap will be very fast on a SSD but will wear it out faster than normal if memory is actually swapped to disk (hopefully that won't happen very often with 4 GB ram). – WinEunuuchs2Unix Sep 12 '16 at 01:25

  • Swap wearing out an SSD faster is a myth nowadays, this really has not been the case for a long time. If you have enough RAM, you basically won't swap at all, or only rarely. And even if you do heavily swap all the time (the sign of a computer with too little RAM), modern SSDs can still take 10, maybe even 100 years of it without longevity ever becoming a problem. – thomasrutter Sep 12 '16 at 02:15
  • Since you seem to have no other drives, there's no difference to other single-drive partitioning scheme. – David Foerster Sep 13 '16 at 06:59

I recently got a 128GB SanDisk USB Fit flash drive for the exact same purpose. I gave 3GB to swap and the rest went to root. Even though my laptop, comes with 8GB my ram usage is sitting at about 3GB right now but this is most likely because I'm running Google Chrome with several tabs open. I would definitely recommend a minimum of 2GB of swap for your setup though.

At first glance this question seems like a duplicate of how-to-use-manual-partitioning-during-installation. Please look at this question and accepted answer for the what you need to do.

Set your swap size to 4GB and hopefully it will be seldom used because swap on a SSD will wear it down faster.

After installation look at SSD life extending techniques such as TRIM and log file writes. In summary:

Add noatime,nodiratime to your ssd drives or partitions, after ext4

UUID=bef10b86-494d-41c6-aa46-af72cfba90fd / ext4 discard,noatime,nodiratime,errors=remount-ro 0 1

UUID is your actual device not the one in the example. For more information read: what-ssd-optimization-are-needed-on-latest-ubuntu-version

Don't worry about these technical details right away. You have lots of time to optimize your SSD life extension. We are talking of extending from 7 years to 10 years probably. Your mileage may vary.

You haven't mentioned any specific requirements that are out of the ordinary, so I would recommend going with the installer defaults.

The installer defaults are carefully chosen to be the best compromise that would satisfy the most situations. The reason you alter defaults is when you have specific requirements, which you don't appear to have.
