If you choose to put all your eggs in one basket for what ever reason then I usually counsel people to make that basket as bullet proof as possible. Maybe you can afford to have some the shelf just in case. Depending on your architecture and it's built in reliability (fail-over clusters and the like) maybe you can live with it being down for a while as you order replacement parts.

How prepared you are to deal with replacement and such when the time comes. By the nature if those types of use those will get over written a lot and that may be worth the extra investment for extended life. The use of your drives: The drives that are housing something very volatile will get beat up a lot more, stuff like caching drives or database tempdb. They are built to run all out for extended periods of time at higher temps in more demanding environments.So please consider a couple things when making this decision: Reliability - Enterprise SSD are made to run in a datacenter environment which typically means a higher sustained operating and level. There are also a few other points that I think make all the difference: That review highlights the differences chief among them SUSTAINED performance. There's a pretty darn good review Tweak Town SSD Review. There is a huge difference between an Enterprise SSD like the Optimus or Sandisk Lightning or the Intel 3700 and the Samsung 840 or OCZ Vector. Without going into a rediculous amount of detail, because I'll let the internet do it for me.
