The truth is, if you go SSD - you will never go back! Some helpful suggestions may be: if you have a data drive (in addition to your ssd) it is a good idea to put your paging file on there. If you can minimise the number of writes to the drive, you will extend its working life considerably, so the best idea is to install your software on the drive and put data elsewhere. It is a good idea to do a fresh installation of your chosen OS, as many modern operating systems are able to recognise SSD drives and optimise accordingly. As with all drives, some people will experience failures, so make sure you backup important data. Sit back and enjoy the most considerable performance improvement you can treat your pc or mac to.
