If you are taking about a Flash based SSD do not worry about wearing it out. You will expire before it will. Also the average life of a conventional hard drive is much shorter. These SSDs are being used in place of mechanical spinning drives in all but the lowest end cheap computers now. They are even being use almost universally in server rooms in web servers that take lots of web traffic.
So don't worry the SSD is now the most reliable storage device you can buy. (Not to be confused to SD cards with have very poor performance.) Infact if you have a PC or laptop and it has a spinning hard drive that it boots from, replace it with SSD right now. Just spend the $100 or so ad do it. It will dramatically improve the performance, like night and day. As for "modifying the OS" to use RAM for storage. No, it is a configuration option (in /etc/fstab) The only reason to use a RAM disk is because you are running off a live DVD file system. If you are booting from a SSD it would be pointless to have a RAM based file system On Wed, Oct 18, 2017 at 9:14 PM, John Dammeyer <jo...@autoartisans.com> wrote: > I do have one question about this module just before I order one.
