Here is what the hdtune benchmark showed for my 3 year old 970 EVO Plus before running SpinRite. The left of the diagram shows the beginning of the drive and the right shows the end of the drive.
As you can see, the drive is performing worse at the beginning of the drive which matches many anecdotal reports.
This is the result after running SpinRite on Level 3:
Minimum speed is 4x better and the whole drive is restored to original performance.
The drive had 32.5 TB written before running SpinRite (34.5 TB after) so this operation added about 6% writes to the drive. But the drive is rated for 1,200 TBW so I have plenty of margin. Will be nice if/when a future version of SpinRite can rewrite selectively though. The drive has 15,494 hours of power-on time so it has been on for about 60% of the time since I bought it.
The level3 operation took 7h 23m. SpinRite's own benchmark shows really bad numbers (314MB/s), not sure why but I guess that explains why the operation took so long. Maybe related to my UEFI/BIOS settings?
