I just bought one of these a few days ago from newegg.com. I use it solely for WoW, nothing else on it yet.

It's my first SSD ever, so I don't know how it compares to others. Usually, loading is near instant and the zone just appears. Sometimes its 2-3 seconds. In Dalaran during primetime with 5 clients - no more invisible toons for 15 seconds, everyone in the city pops up a few second after zoning in.
