some questions about the data

[cighao]

Hi. It's a very nice website. But I have some questions about the data. On the website, "read 1000,000 bytes sequentially from memory is 3us", so the memory bandwidth should be 1MB/3us = 333GB/s. "read 1000,000 bytes sequentially from SSD is 49us", so the SSD bandwidth should be 1MB/49us = 20GB/s. "read 1000,000 bytes sequentially from disk is 825us", so the disk bandwidth should be 1MB/815us = 1.2GB/s. From my point of view, these data are much bigger than the real products' performance.

It looks like the numbers are currently projections from 2012???

Here are some reasonable bandwidth numbers: https://www.forrestthewoods.com/blog/memory-bandwidth-napkin-math/

That's correct, I created this in 2012 ;-)

Happy to accept pull requests for updated models
