What settings can I use to preserve the SSD?

Is everything correct in the chatbot’s answer? Should I use a flash drive or hard drive for the swap file?

There are several settings you can configure in Manjaro Linux to preserve your SSD and extend its lifespan. Here are some tips:

  1. Enable TRIM: TRIM is a command that helps to maintain the performance of your SSD by informing it which data blocks are no longer in use and can be safely erased. To enable TRIM, you can run the following command in the terminal:
sudo systemctl enable fstrim.timer

This will schedule TRIM to run automatically once a week.

  1. Use a swap file instead of a swap partition: By default, Manjaro Linux creates a swap partition during installation. However, swap partitions can cause a lot of unnecessary writes to your SSD, which can reduce its lifespan. Instead, you can use a swap file, which is a dedicated file on your filesystem that serves the same purpose as a swap partition. To create a swap file, follow these steps:

a. Open a terminal and run the following command to create a 4 GB swap file:

sudo fallocate -l 4G /swapfile

b. Set the correct permissions on the file:

sudo chmod 600 /swapfile

c. Turn the file into a swap file:

sudo mkswap /swapfile

d. Add the file to your system’s fstab file:

sudo echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
  1. Disable unnecessary services and daemons: Some services and daemons can cause unnecessary writes to your SSD. For example, you can disable the atime option on your filesystem, which causes the system to update the access time of each file every time it is read. To do this, add the following line to your /etc/fstab file:
  1. Move your temporary and cache files to a RAM disk: Temporary and cache files can cause a lot of writes to your SSD. To reduce this, you can move these files to a RAM disk, which is a portion of your system’s memory that is used as a filesystem. To create a RAM disk, follow these steps:

a. Open a terminal and create a directory to use as the mount point for the RAM disk:

mkdir /mnt/ramdisk

b. Add the following line to your /etc/fstab file to create a 2 GB RAM disk:

tmpfs /mnt/ramdisk tmpfs nodev,nosuid,size=2G 0 0

c. Move your temporary and cache files to the RAM disk:

sudo mount /mnt/ramdisk
sudo ln -s /mnt/ramdisk /var/tmp
sudo ln -s /mnt/ramdisk /var/cache

By following these tips, you can help to preserve your SSD and extend its lifespan.

A flash drive is both slow and has a low lifespan eg breaks after x writes in the long run…

You should ask that question to it also :rofl:
