  • The best way to speed up Catalina, sadly, is to run off an SSD or if your system is equipped with one, an NVMe drive. APFS is really craptacular on anything but NAND based media and Catalina forces APFS now, so having solid state storage is hands down the number one way to speed things up.




  • Thanks for the useful tips. Concerning the User-Interface Performance (Reduce Motion & Reduce Transparency), also useful is

    Apple – System Preferences – Accessibility – Zoom – Smooth images (turned OFF)

    Finally, in relation to External Storage, please bring much larger capacities without RAID. The latter may be good to increase performance on some tasks, like video editing. But increases failure rate more than twice (two blades) or more than five times (four blades) if one of the SSD blades or the controller fails. That is now possible with the new high-capacity SSD of 4 and 8 TB on a single disk (no RAID involved):

    • I personally like external storage systems that have multiple slots or bays. I have limited ports on my Mac, and having a single connection to multiple volumes works fine for me.

      In many cases the multiple-drive external enclosures can be used sans RAID, which is how I use them as individual independent drive each showing up as separate volumes on the desktop.

      The option to use a RAID array to increase performance is appropriate for some uses, and having the choice in how the drive bays are configured is a big plus.

      I’m showing my age now, but when you mentioned 4 TB and 8 TB SSDs, my first thought was how the 20 MB SCSI drive connected to my Mac Plus was huge and I would never run out of space!

      • Thanks. External storage systems that have multiple slots or bay are certainly useful as desktop storage.

        But when you need portability to carry in your pocket, nothing like a small and light portable SSD. Some of them weight just 51 grams and are smaller than a credit card. They are up to 2 TB now, and hopefully 4 TB & 8 TB soon, as said above.
