I handle lots of large and small files around for engineering data logistics, and wanted to describe (nothing scientific) my take of real world SSD speed, to see if you guys agree.
5400 RPM to 7200 RPM HDD: quite noticeable
7200 RPM to SATA SSD: day and night... can't go back
SATA SSD SATA2 port vs SATA3 port: surprisingly hard to notice
Old Slow planar TLC SATA SSD vs modern SATA SSD: more noticeable than SATA2 vs SATA3 for writings
SATA3 to NVMe: surprisingly hard to notice. Things feel snappier but barely noticeable... Large files obviously transfer significantly faster but not for long.
I think maxing out SATA3 bus speed is pretty much the threshold of human sensation of SSD speed. We don't seem to benefit a lot by going faster than that.
