Hi, I'm a new HD Sentinel user.
I bought a new 6GB HDD to connect via usb c 3.1.
When I started the quick tests the HDD was noisy but it stopped shortly after.
Then I started the test on the surface for write / read but, due to problems with the mains that forced me to restart the test a couple of times, I postponed to proceed to connect the disk to the UPS.
Restarted the test with the disk connected to the UPS to my surprise I observed a speed of execution of the write test of 39 mb / s, with an estimate for completion of 89 hours!
The previous day I observed speeds of 150mb / s and an estimate of the time it would take to complete the test of 16 hours.
Why this difference?
