An HP laptop which uses a small SDD 128Mb, large HDD, I have never opened it up to take a look, but might it be possible to swap out both, for a single SDD, or just swap the HDD for a SDD?
It was my fastest system, replacing a much older slower Acer laptop, but since swapping it's HDD for an SDD it is now much faster than my latest laptop.
Try to gather what info you can, for better service.
msinfo32.exe is a Microsoft utility in the OS, you can try.
Really, the sum total of utilities is wanting, so it normally takes a battery of utilities, to spell out the details.
In msinfo32.exe : Components : Storage : Disks will be the names of the disks.
It doesn't tell you there, how they're connected. Whether a SATA cable, NVMe slot, or whatever.

A Linux DVD live session and inxi -F will give a summary.
The summary isn't perfect, as it might not name the HP model, so you'd have to check. It also seems to be missing the DVD drive. I just copied a few lines of it, that identify hardware.
Drives: Local Storage: total: 7.29 TiB used: 43.6 MiB (0.0%) ID-1: /dev/sda vendor: Samsung model: SSD 870 EVO 4TB size: 3.64 TiB <=== sata cable ID-2: /dev/sdb vendor: Samsung model: SSD 870 EVO 4TB size: 3.64 TiB <=== sata cable ID-3: /dev/sdc type: USB vendor: SanDisk model: Ultra size: 14.53 GiB <=== USB boot stick (Linux)
In Linux, the NVMe and eMMC storage types, have distinctive strings after /dev, hinting at how they're connected. Presumably a plugged-in SD would have a distinctive name too. My optical drive should be /dev/sr0
