    I heard from a colleague at work that SSDs that run the OS fail within 2-3 years. This is due to the fact that they are constantly read/writing from the SSD but not distributing it within the entire disk, so the SSD fails much quicker than standard HDDs if you use the OS on it daily.

    And this is nonsense there are lots of SSD longevity studies.

    It's scaremongering from the early days of SSDs as self proclaimed experts didn't understand how they work internally. Wear levelling in the drive firmware, coupled with garbage collection and TRIM make efficient user of the write cycles. See the extremetech articles linked above.
