I'm very disappointed to hear the SATA port is a big bottleneck. I was hoping to use 6 of these to build a database cluster (Cassandra NoSQL) but it sounds like the board is not suitable. Fortunately I read your review (Thanks!) before buying 5 more boards. I'll probably use the board for some other purpose. If you know of a single board with real SATA and good integer and floating-point performance, I would love to hear about it. I also have another application where I need the performance but not SATA. More RAM would also be great. I'm considering whether I should build my own board. By the way, my board is from Eleduino but it appears to be a clone of the SinoVoip board (or vice versa).
