Just read through the discussion page for the downed DB and had some thoughts...

...I was thinking what Amazon offers for EC2, however I don't see anything they offer that would work for your stats DB. While there would be enough memory (68.4GB - High-Memory Quadruple Extra Large Instance), at $2.00/hr that would get expensive quick.
Just out of curiosity, how often do you download, parse and update for the stats? I'm wondering if you decreased the frequency, if that would ease up on the DB replication or have the opposite effect (wearing down the SSD at a faster rate).
EDIT: Side thought, what about a hybrid drive? I (at my job) have been testing Hybrid drives with the developers for SQL Server/Visual Studio work and we've noticed comparable performance to a standalone SSD. They appear to work very well, but then again, we ain't running DBs 24/7 on the drives.
