Hey - I know a bunch of you own Airs and Retina MBPs.  How full can you fill the SSDs without running into problems?  More than the ~80% max we have on platter drives?

Hi Julie.

SSD's use the same filing system as HDD's - HFS plus. The 80% recommendation is a feature/limitation of the the filesystem not the drive itself.

 

Having said that, many SSD's use self-optimising routines that make storage more efficient, but this (in most cases) should be transparent to the user.

 

I think you can reasonably happily approach 90% full on most drives. The issue with that is there is no room to grow.

 

Any engineers out there have a different viewpoint?
