My Disk Speed Test scores are ~90/90. Is that merely a function of the boot drive? Or are there other things that could be changed to improve those scores?

Thanks.

It depends on what kind of drive you refer to.
For all kinds of drives (HDD or SSD) speed will decrease if there's less than ~20% of free space.
SSD drives get slower by the years depending on the amount of i/o writes..

If it's an SSD enabling TRIM is recommended by this terminal command: sudo trimforce enable
This can improve i/o speed of the SSD in case it has been used a lot without TRIM.
If it's an SSD mounted in a SATA bay /optical bay, speed is limited to SATA-2(~300mb/s).
One could install an PCIe adapter to get SATA-3 speeds(~600 mb/s ) e.g. Accelsior S.
Backdraws are that the drive will be seen as external by the OS and the speed improvement is not very spectacular thus maybe not worth ~ 50,- ...

The speed of i/o is independent if its the OS disk or a data disk.

Yeah, I was recently advised as to how to turn on trim, and my speeds went up to ~242/265.
