Would recommend adding the specific SSD model and also adding some fio benchmarks to show the real limits of the ssd.

SSDs can be connected to a machine through raid cards or some enclosures etc. etc. And all of this makes massive differences compared to a proper on-board PCIe connection.

Also obviously SSDs have very vastly different performance characteristics.

For example an ssd might look very good at writes until you keep writing for more than some amount without any breaks, and then it becomes super slow.
