Consumer SSDs used to max out at about 550MB/s, some still do. You need a larger and more modern drive to do 1.25GB/s sustained write. Even then buffering can get you.
- Dalewyn 4y agoThat's due to the communication protocol. 2.5 inch and M.2 SATA SSDs max out around 550MB/s due to the limits of SATA3 connections which cap out at 6gbps. M.2 NVME SSDs meanwhile communicate over PCIE, generally using four lanes, and the latest PCIE5 SSDs can do around 15GB/s if I recall. PCIE4 drives can get up to around 7GB/s, and PCIE3 drives up to around 3GB/s. Other potential bottlenecks can occur with the motherboard chipset, controller, and NAND flash, but details. TL;DR: Any NVME SSD can saturate a 10gbps ethernet connection.
