The speed of my Disk is about 450 Mb/s read and 150 Mb/s write
I have a question. The speed of my Disk is about 450 Mb/s read and 150 Mb/s write. (maybe because the disk structure of Catalina is with a virtual partition as read only, I do not know)

Hello:
Replace the HD for the new SSD. Maybe the problem is the SSD disk. It is a WD green 1Tb
In my test made with BlackMagic give 166 Mb/s - 415 Mb/s
But for the limitations with the read only disk, skip a lot test.
Before include my User from High Sierra, start up only in 20 seconds. Now it's about 45.
