Bootup speed

[PEDRO524]

I have upgraded my RAM to 16gb, removed mechanical HDD and optical drive and replaced both with two 500gb SSDs, but boot still lags. I use one as tye main boot up drive and the other one as internal storage. What can I do to improve boot up time and overall speed? Is raiding an option?

Make sure the drive in the optical bay is not the boot drive.

Is it possible the SATA drive cable is not quite up to spec?

Too many apps loading at start up?

The SSD should NOT be connected to the optical bay connector.
Use that one for the platter-based data drive.

One other thing:
Did you go to the startup disk preference pane, and reset the SSD to be "the new boot drive" ?

By never shutting your Mac down, you won't have to worry about boot up speed. Just let it sleep.

Try going into System Preferences > Startup Disk and selecting the appropriate drive.
