A fresh look at storage performance with PCIe SSDs
 

For years, SSDs thrived under the Serial ATA banner. New generations got bigger, faster, and cheaper. Prices continue to fall and densities continue to increase, but performance has been stagnating for a while. The problem is the SATA 6Gbps interface, whose limited bandwidth keeps modern flash storage from living up to its true potential.

Fortunately, SSDs aren't inexorably tied to Serial ATA. They can tap into PCI Express, which promises substantially more bandwidth through faster signaling and ...
