MP 7,1 Slow internal SSD speed?

[Aboo]

Hi Team,

Anyone having experiences with slow internal SSD speeds- I have the 4TB configuration on my Mac Pro, and with black magic speed test, I am noting internal SSD speeds of around 620 MB/sec write, and over 2800 MB/sec read with the standard 1GB stress. It will occasionally rise up to about 1800 MB/Sec on write, but then drops right back down. Short of doing a wipe and clean install, not sure if anyone has any brilliant suggestions.

Thanks!

We need to know the details of your SSD, not the 7,1.

Ah - Its the standard stock 4TB SSD. Apple installed.

That's strange. I wish more 7,1 owner can tell you if their 7,1 perform the same.

The symptom points to your SSD run out of cache very quickly. Or TRIM isn't working etc. But for Apple stock SSD, this shouldn't happen.

ok thank you for taking the time to respond. I have more than 70% free on this SSD so don’t know what the issue can be. I think I may just try to reformat and do a fresh install to see where things go.
