              Howard Oakley Determines the Best Disk Image Format

   Adam Engst

   At The Eclectic Light Company blog, [1]Howard Oakley writes:

     Over a year ago, Apple changed the way that one of the most popular
     formats of disk image works on APFS. This article re-evaluates the
     more common general-purpose formats in light of that change. Now
     that plain disk images can be highly efficient in their use of disk
     space, should you make more use of them?

   When creating disk images in Disk Utility, I've long wondered which
   format to choose. Howard Oakley has now done the Mac world a service by
   comparing the three main types'plain read/write disk images, sparse
   images, and sparse bundles'on space efficiency, performance, and
   convenience. Read his full article, but I'll stick to sparse bundles
   whenever possible (and plain read/write disk images when not).
