Difference in SSD speeds?

[Suno]

Now we all know SSDs are super fast, but I'm just curious to know from users of different SSD's -- Is the speed difference between one SSD even noticeable to a slightly faster SSD? Say for example, one SSD "only" reads up to 400 MB/s while another reads 535 MB/s. Would the slight increase in read speed warrant an increase in price?

Not really. It is mostly imagination.
Only some really heavy duty stuff may show a benefit. Like running some server workload.
There is a difference in file copy speed and extraction between a sata 2 and a sata 3 drive and between the really fast write speed SSDs like the 830. Quick feel and app launches, boottimes aren't really significantly better with a slightly faster SSD. Nobody feels the difference between 4.5 seconds or 5.5 seconds launch time.
HDDs are much slower especially if multiple applications want something at the same time. An SSD is like a multi core CPU compared to a single. Yet usually the CPU limits before you notice a difference with a faster SSD.
