| Why does Sonnet use only PCIe 2 to connect the two controllers on these 4-port USB 3.2 Gen 2 cards? | Apr-18-21 |
| We connect each USB 3 controller with two lanes of PCIe 2. Each controller has 1000MB/s bandwidth which is enough bandwidth for the fastest devices you can connect, such as USB 3.1 Gen 2 NVMe SSDs. Because the read/write bandwidth is independent, on one controller you can be reading from one SSD at 1000MB/s, and writing to another at 1000MB/s, plus the same on the 2nd controller for an aggregate transfer rate of 4000MB/s. What makes this possible is that Sonnet uses the advanced ASMedia 3142 Controller that supports Multiple INs, which means that reads can commence on one port before a write has competed on the other port.
A PCIe 3 Bridge chip would cost you $50 more, but would give you incremental performance only if you needed to continually simultaneously read--or simultaneously write--to four USB 3.1 Gen 2 NVMe devices, a very unusual use case.
