I would like to know if I maxed out speed on my vintage MacPro. I have 4 interal ssd that are rated upto 550mb/sec write and 420mb/sec read. I am getting average 255mb/sec write and 266mb/sec read. I am attaching a Geek bench score that show my MacPro specs.
Mac Pro, macOS 10.14
As mentioned in passing above, your Mac Pro 5,1 has only a SATA-2 capability in its main drive bays (300 M Bytes/sec). That can't hurt any Rotating magnetic drive you can put in there, but will slightly clip a 500 M Bytes/sec drive. (which seems to be what you are experiencing)
If what you need is more drive speed, a PCIe slot card can go faster. Most walk away from SATA drives and use other, faster interfaces, but OWC sells a card that will take your 500 GB/sec drive if you hate to set it aside.
Be sure to use a card with a heatsink -- as you go faster, the SSD drives will get hot, and they throttle down when pushed too hard.

That data is useless currently. The data we need is the model of the Mac Pro. Some have link speed of 1.5 or 3.0 or 6. which effects the speed of a so called great SSD. That single core score is LOW which I'd guess the model is the original Mac Pro.
If you click on below my message is the full specs under GeekBench 5 score. Hope this help:

Your SSDs look healthy and as @Grant mentioned they are restricted to SATA II speeds of 300MB/s. You may want to consider enabling TRIM on the SSDs by using the following Terminal command:
sudo trimforce enable
If you don't enable TRIM, then I recommend you uncheck "Put hard disks to sleep when possible" so that the SSDs' internal garbage collection routines have time to run when the SSDs are not being actively used.
You need to uninstall ESET and CleanMyMac by following the developers' instructions. Anti-virus and cleaning apps are not needed on a Mac and usually causes more problems than they solve plus they impact system performance.

In what way(s) does this Mac fall short of your needs?
My 2014 Macmini has the same Samsung ssd and speed write and read is double my MacPro. J
Thanks Grant, I was curious as to why and I am glad to know it just a limitation of the drive bays.
Thanks for your advise. I did uncheck put hard disks to sleep when possible. As far as enabling TRIM, I have no idea how to do that.
ssd is slow
