I'm wondering if it would be a good idea to use a new SSD for moving all the disk i/o to, that Linux likes to do so often. Plus putting SWAP onto a decent SSD should speed things up somewhat.
As far as I understand, SSD are fast at reading and slow at writing. They are strong if data rarely changes and if it is mainly read like root partitions.
This may be useful for webservers that hold the content in /var/www.
Putting your often changing data like swap and /var/log on a SSD may slow down your system.
A swap partition is used to save expensive RAM. Don't use much more expensive FLASH-ROM to replace it.
Beside that, if your system is heavily swapping, a SSD will wear out quickly.
OK Michael. Thankyou for that - I understand what you are saying.
Regards,
Keith
