The positives are a much larger "randomly addressable" memory pool. The
negatives are that its still flash (for the moment), and has all the
issues associated with flash (random small writes == very bad).
For read heavy workloads (in memory databases, etc.) its wonderful. For
write heavy workloads, you'd want to make sure the devices were hot
swappable (DIMMs aren't except in specific cases).
