I'd believe this, that's the worse part. Recoloring several objects and constantly reloading the same categories over and over when you just had to wait for it on the previous item. It is faster than it was before and somewhat tolerable on my new computer, I can deal with it, I just wondered if there was something else I can focus on to speed it up.
You can easily copy the color of one object to another object by dragging a single box from the mesh mask panel to the object you want to recolor. The object should glow when you drag your box over it. You can also drag the entire panel to the object you want to copy the entire style and not just the color.
That's a reasonable HDD as far as speed, the "green" ones usually run around 5400RPM, give or take. The only thing faster is either a velociraptor drive from WD which spins at 10000 RPM or a SSD which have read/write speeds considerably faster again.
Although the read/write speeds of a SSD are considerably faster than an average hard drive, SSDs are not cheap with a 512gb going for $1000 and a 1tb going for $4999.
