To be frank, one person's experience with an SSD's lifespan should not have any impact on your decision. The reality is that SSDs are doing very well, most brands are very reliable, and the feelings regarding them are OVERWHELMINGLY positive. There are always people who are worried about change, but it doesn't take a rocket scientist to look at the inner workings of both storage mediums to decide which would be more likely to last if all else (quality etc.) is equal.
Additionally, NEVER EVER EVER buy a storage medium because it's reliable to replace redundancy AND backups. Don't trust anything with your data.
Your friend is right. Two raptors in raid 0 is likely still going to be notably slower than a single SSD.
What does your friend do? This is a huge waste as a gaming machine, or likely even a workstation for one user. It's entirely plausible that it will actually perform significantly worse than usual off-the-shelf stuff unless we're talking about some kind of rendering or scientific processing... but the HD throughput is awesome.
Given that, it would actually still be entirely believable to find out that a $300 SSD would still have better random read/write speeds
