I confirmed that the backup and verify times were virtually identical to the times I had previously seen.
I then installed the 5.5.2.1 release version and ran the backup and verify times again.
This is when I noticed that the backup time had stayed roughly the same using a USB SSD, but the backup time had increased on a USB HDD.
The tests were performed within a few mins of each other, so the only change was the Hasleo version.
I will try to run the same tests on another PC later and report back the results.
Thank you. I believe we should conduct multiple rounds of testing separately to minimize random errors and arrive at the fairest possible conclusion.
I have now run some tests on a different PC with the backup files going to an internal SATA 8TB HDD and an external USB SSD.
Hasleo V5425 Backup Time Verify Time Size
Ext USB SSD 0m59s 1m 54s 36.8GB
Int SATA 8TB 4m 22ss 8m32s 36.8GB
Hasleo V5521 Backup Time Verify Time Size
Ext USB SSD 1m01s 1m 54s 36.8GB
Int SATA 8TB 6m58s 8m12s 36.8GB
If anything, the difference is even more marked on this PC between V5425 and V5521 backing up to the internal SATA drive,
4m22s vs 6m 58s.
The time for the ext USB SSD is fairly similar between the 2 versions.
Obviously, it would be nice to use an SSD to hold the backups, but it becomes expensive if you want to hold a lot of backups.
I'm sure it would be of benefit to most people to optimise the backup and verify times on Spinning HHD as well as SSD.
