The whole discission started with software crash (nVidia drivers are very helpful here). I fail to see how these "new century" toys can help against this.

A software crash is less severe than a power failure, because file systems that don't use barriers properly (e.g., ext3 by default) will see all their writes come through to the disk drive, but on a power failure some writes may not have been carried out, whereas some logically later writes may have been carried out. As a result, such a file system can become inconsistent on power failure even if it does not get inconsistent on a software crash.
