[Elecraft] HRD question

[Walter Underwood]

SSDs should not need de-fragmenting.

The problem with fragmented disk volumes is that the parts of a file get scattered all of the disk. That means it takes multiple seeks to get an entire file. De-fragmenting organizes each file in neighboring blocks on the same cylinder, so the file can be accessed with the fewest number of seeks.

SSDs don’t seek. Any block anywhere on the SSD can be read with no delay.

The only effect of de-fragmenting an SSD would be to shorten its lifetime by doing unnecessary writes.
