Different time on each boot

With the dmesg command I noticed that the disks are mounted at different times for each boot. Ubuntu 20.04 dual-boot Windows.

Fast boot:

$ dmesg 
...
[    5.870528] EDAC amd64: F15h detected (node 0).
[    6.490309] EXT4-fs (sdd2): mounted filesystem with ordered data mode. Opts: (null). Quota mode: none.
[    6.634475] EXT4-fs (sdb2): mounted filesystem with ordered data mode. Opts: (null). Quota mode: none.
[    6.658732] EXT4-fs (sdc1): mounted filesystem with ordered data mode. Opts: (null). Quota mode: none.
...

$ systemd-analyze blame

1.270s snapd.service      
...

(sdd2) (sdb2) (sdc1) are mounted quickly.

Slow boot:

$ dmesg
...
[    8.596732] usbcore: registered new interface driver snd-usb-audio

$ systemd-analyze blame

...

(sdd2) (sdb2) (sdc1) are mounted with a delay of almost 4 seconds.

Maybe I did something wrong in the /etc/fstab?

Why does this happen? Is there a way to always mount the disks at the same time as in fast boot?

Thank you guys :)

I installed Ubuntu in dual-boot with Windows. The partition where Windows is installed is not mounted in /etc/fstab because it is not needed. If it helps, Windows starts very rarely. Months can go by without using it.

Sorry I misread your question. Your problem may not be related to Windows, at least not in the way I was thinking.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
