Wait until they find out how much space is on their 2TB SSD…
That difference is because the drive manufacturer advertises capacity in Terabytes (or Gigabytes) and the operating system displays drive capacity in Tebibytes (or Gibibytes). The former unit is based on 1000 and the latter unit is based on 1024, which lets the drive manufacturer put a bigger number on the product info while technically telling the truth. The drive does have the full advertised capacity.
Hz are Hz though
Drive manufacturers aren’t really at fault here. As long as you use the proper units everything is in order. There is no reason for drives to be an exact power of two, so TiB and 1024 don’t really make sense here. The biggest offender and the only big player that still does it wrong is Microsoft by using non-standard units. The history behind the 1000/1024 confusion is IMHO really interesting: https://zeta.one/kilobyte-is-1000-bytes/
Units are important!
