On Linux an SSD will last for a very long time. If you are paranoid you can use the suggestions on the LinuxCNC wiki for compact flash cards but it probably isn't necessary. I would't run an SSD on Win7 or Win8. They thrash the drive nearly all the time and will wear out an SSD surprisingly

We have something similar on the KT. You do need to get used to the 'feel' of the keys. It reminds me of typing on a mechanical typewriter. (strait down with some force) It is working well and it get a bit of swarf on it from time to time. sam On 8/2/2012 9:01 AM, John Kasunich wrote:
