I linked to a category of products; Internal SSDs which directly connect via PCIe. Currently 27 listings in that category. Lots of neat stuff. As for systemic performance...I'm certain your controller being only one PCIe lane is a major limiting factor. Beyond that, there are a lot of factors which weigh into SSD performance...which at least a few people in here (such as Neil) can tell you about. I only know things like SLC is often faster than MLC, that the on-drive controller's properties can have a major impact, and that SSDs are mostly awesome due to low latency. -- :wq
