I am about to make some hardware upgrades to my Linux box, and one of the possibilities is to add an SSD drive for /, /boot, and possibly also swap. Anyone have any advice on potential issues with the above?
Use SSD for everything that requires good interactive performance. If you need bulk storage then use a RAID-1 array of cheap big disks (3TB or 4TB) for that. Write a cron job that backs up the SSD to the RAID-1 array because you don't want all your data only on one device. My wife's workstation/server has a 120G Intel SSD for boot, root, swap, and home (using BTRFS for root and home) and a pair of 3TB SATA disks in a BTRFS RAID-1 array for bulk storage. I have a cron job that creates snapshots of /home every hour and another cron job that copies a snapshot of /home to the RAID-1 array every day. The hourly snapshots cover the case of accidentally deleting the wrong file (the most common use of backups) and the daily copies cover the case of the SSD dying. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
