Almost 10 times better raw write, and about 3 times better on buffered reads. If IO (and more specifically mysql) is your bottleneck, which is likely the case with high volume WP network sites or with LAMP apps like 202, this SoD option gives performance that kicks the crap out of of more expensive dedis offerings with the convenient backups, console and scaling the SoD platform is known for.
