Sequential Writes

Hi 

I am writing pseudo-random data worth 200 GB sequentially to the SSD. The actual file size on the SSD is 186 GB ( total writes ) whereas the same data is exactly 200 GB on a normal partition ( HDD). 

First I thought it was compression, but it isn’t.

It isn’t 1024 vs 1000 either.

I am not sure as to why this is happening. Any help would be appreciated. 

Thanks

I am probably a little bit late, but…

200 GB * (1000^3) / (1024^3) = 186.26 GiB
