    When to select 1024K cache tile size versus 1028K size in Preferences > Performance...

      I'm interested to know which option to choose. I see significant performance improvement using 1024K over 124K or 132K on my system on the kinds of files I usually work with: 100+ pixel layers, vector layers, type layers, masks, effects on 1600 x 1200 px images; and ~14 MB Nikon NEFs, DNGs with only a few adjustment layers and/or masks.

       

       

      But what about 1028K?

       

      I'm guessing this has something to do with disk block size.

       

      I'm using a 17" MacBook Pro i7 with 8 Gi RAM, and 2 internal 200 Gi OWC Mercury Extreme SSDs set up as a RAID0. The block size on my RAID volume is 32K. It's both my Startup disk (and Application volume), as well as my only Scratch volume.

       

      Thank you!
