Fedora release 38 (Thirty Eight)
My HP Omen laptop has the following specs:
256GB NVME SSD drive
2 TB SSD Hard drive
Its a dual boot configuration: Fedora 38 and Windows 10
The laptop originally came with 1TB Mechanical SATA disk drive (2.5 inch internal HDD). I upgraded it to a Sandisk 2TB SSD (2.5 inch) Hard drive.
For faster performance, both Fedora and Windows OS are installed in the NVME drive.
Fedora OS runs from /dev/mapper/fedora_rootvg-root which is created NVME partition /dev/nvme0n1p7 as shown below.
To store my personal data, I use the 2 TB drive. Fedora assigned the name /dev/sda for this drive.
Now, /dev/sda is an SSD but it used to be a mechanical disk based HDD.
For my personal data, I created the LV /dev/mapper/fedora_homevg-home which is created from /dev/sda3 as shown below.
/dev/mapper/fedora_homevg-home is mounted on mount point /home .

My question:
When I was using 1TB Mechanical SATA disk drive and when I launch Firefox browser, it took roughly 1 minute to load.
But, when I upgraded the HDD to a 2TB SSD, the firefox browser starts almost immediately. Its fast.
I presume all softwares like firefox was always installed in the following filesystem which is created from a NVME partition.
So, how did an upgrade from mechanical disk to SSD make loading for Firefox browser faster ?
