I have not heard argument about ssd in high write applications. I put one in my core and it seems to me that the core and my mds boot faster. The last time I researched the topic, which was a while ago, linux wasn't able to unleash the true performance capabilities of a ssd. It would still be faster than a conventional hd but no where near as fast as the same ssd running windows. I didn't do it so much for speed, I was after the reliability. Typically they out last conventional hard drives.
