Maximize SSD lifespan for Windows Server 2008 R2 OS drive?

I have a solid state drive for my operating system on my server, Windows 2008 R2.
I have read that these drives degrade as they write.    My server has 2 SSD drives and one spinning drive for misc data.

1.  Should I move my pagefile off the SSD drive?    
2. Was this a bad idea having my Server OS on an SSD (including MSSQL)?
3.  How will I know when my disk is being 'degraded' and when should I consider moving my server?

My server is an ASP.NET webserver that dishes out about 800,000 pageviews a month, that interact with SQL server.....all running from 2 SSD's  (1 SSD is the OS and IIS, the other is Email, and SQL)

Here's a good read that addresses your concern.

Regarding your page file, if you increase your RAM then you'll use it less, or you can even get rid of it.

most of your worries date from the first SSD drives, that had some problems, so for now, don't worry

           Not unless you need to. If Performance is an issue then yes. As said increasing RAM will reduce the reliance on Pagefile, but i certainly would not recommend getting rid of it alltogether from a server environment.'

2. Was this a bad idea having my Server OS on an SSD (including MSSQL)?
           No. you want the data that needs to run the system to be on the fastest, most stable platform.

3.  How will I know when my disk is being 'degraded' and when should I consider moving my server?
         As said their are tools to monitor. But just like any electronic device they can fail at anytime with or without warning. You can mitigate this with RAID or reduce the recoverable point in time with backup solutions like shadowprotect. You MUST be prepared for the drives/server to die at any time, because sometime between now and infinity, it WILL.

If the drive is good aligned then you do not need to worry. The lifespan of the drive will be approximately the same as the lifespan of spinning drive.

If you have TRIM enabled on the OS, which is supported in 2008 R2, it will even out the wear automatically.  As longs as you do not use all the capacity on the drive, it will function normally (a full drive with no free space will suffer accelerated wear problems).  You should not worry about the way they are being used now if TRIM is on, regardless of whether you have Intel drives or not.
