Another issue to consider with SSDs is that they are based on Flash technology. Each flash cell can only be written on about 10,000 to 100,000 times or so (*), so if you're using extensive read/write on your server you will be impacted. SSD manufacturers go around this issue by giving some intelligence to the drive controllers, so that they minimize the per-cell usage (which means moving things around a bit internally, transparently to you), so in many cases you will not see any impact. However, I would be careful on what I run on it, and what services are enabled, maybe having another disk around for write intensive apps.
