USB 3.0 HDD low speed after spindown

[SES]

Hello!

Board: Orange Pi 3 LTS

SATA-USB3: Bus 002 Device 003: ID 152d:0578 JMicron Technology Corp. / JMicron USA Technology Corp. JMS578 SATA 6Gb/s

Speed after load: sudo dd if=/dev/sda of=/dev/null status=progress ... (5,8 GB, 5,4 GiB), 50 s, 115 MB/s

Speed after spindown: sudo dd if=/dev/sda of=/dev/null status=progress ... (4,5 GB, 4,2 GiB), 71 s, 62,9 MB/s

After reboot the speed is again 115 MB/s

The drive does not respond to changes in Power Management settings.

Help me solve the problem.

Sometimes the disk cannot start after spindown.

Thanks!

Just to rule out one possibility, Have you tried using a different power supply? What power supply you are using right now? Orange Pi recommends 5V 3A supply

I use an 18W tablet charger.

Maximum consumption 1.4A when executing the command dd if=/dev/sda...

At rest, with the HDD spindle rotating, the consumption is 0.7A.

I found a solution to the problem I described (a crutch, of course, but still): query the disk status (hdparm -C /dev/sda) every 60 seconds. And the disk never resets.

Maybe someone will suggest the right solution.

Thank you.

not designed for variable loads. Voltage probably breaks down on load spikes.
