I am deploying a new backup drive for my pc. I plan to do image backups, supplanted by incremental backups, unless space gets cramped, then switch to differential. Also on the drive, might be extra copies of folders for a quick copy to the drive or camera card dumps (.nefs) until they get on a DVD. I expect the image files to be large, but possibly no larger than 2 GB in some cases so I can upload to an inexpensive online storage facility that has a max file size.

Typically, the allocation size for current computers just about always falls to a recommended 4K.

But, for this backup drive being used for images and incrementals, if I were to increase the allocation size, will there be any appreciable increase in efficiency, or drive reliability? If so, would I bump it to 8K or 16K?

specifically, a 1T WD Black, SATA III ports for now / then a USB 3.0 enclosure.

Don't bother, unless you are going to micro-manage everything, and even if you do, do that, you won't really notice anything different 99% of the time.
