Yes this question has been asked a million times but I am going to ask it again. Everything depends on what the server is doing and running and everyone is different. I am looking for a "generic" answer. It is going to be an entry level server. Windows 2012 something. No SQL or intensive database. Just a general purpose server for 20-25 users. I am going to run a Raid 5. That being said which would be better, SSD or 15k SAS?
As kind of a side question I have heard that longevity is a problem with MLC SSD drives. Is that true?
