Other SSD users
might simply be wanting to run things just a whole lot quicker.
For example VM's. Frankly when I have to run a VM from a spinning rust drive, I feel that it just crawls alone like a snail.
I've bitten the bullet and relaced the spinning HDD's on my home kit with SSD's over the past two years.
HDD's are for backups only these days. I know that I'm not alone with this approach.
Some of my Photos are more then 70Mb in size on disk (.PS format). Opening them from an SSD is just... faster.
