PCIe Interface For SSD

• In 2007, Fusion-IO introduced an SSD on a controller that attaches directly to a PCI slot.
• This bypasses the slower interfaces, and allows for read latency of ~60 micro-seconds (for SLC FLASH) or a little more (for MLC FLASH).
• This can also use the 2GB/second throughput of PCIe (vs. 300MB/second for SAS/SATA and 600MB/second for SAS2).
