I used to backup on a USB flash drive, it was slow, and the drive became very hot in the middle of backup, so I bought a fast external SSD drive (2,800MB/s) which connects through Thunderbolt 3.
But a 60GB backup with Time Machine still takes about "1:30-2 Hours"...
Is this normal? I thought it would be a matter of minutes with this drive :(
macOS is Mojave if that matters, and I'm taking Encrypted backups on a
Mac OS Extended (Case-sensitive, Journaled, Encrypted) formatted drive.
P.S. I found this command:
sudo sysctl debug.lowpri_throttle_enabled=0 while googling for this matter, but it is for 2017, not sure if it is still useful and a good idea on macOS Mojave?
I am using a 2019 Macbook Air, my read speed is 650MB/s using this command:
time dd if=/dev/zero bs=1024k of=tstfile count=1024
That's still 38GB per minute.
I also tried reformatting the drive to:
CoreStorage Logical Volume • Mac OS Extended (Journaled, Encrypted) (not case-sensitive)
