Yep, it looks like the Asus comes equipped with a Sandisk ReadyCache SSD connected to a port on the board
searching for the drive listed in your DevMgr returns: SANDISK READYCACHE SSD
This page references a 32 GB drive, yours is 24 GB - just a capacity difference.

Desktop computers running the Windows® 7 or Windows 8 operating system. An open SATA port must be available on the motherboard to install the SanDisk ReadyCache SSD

I suspect the cache holds the OEM Recovery (based on the partition Type) but it would make more sense for it to also hold boot contents.
The drive might be put to better use, but that will take a lot of looking. In the end, very little might be changed - perhaps only placing the Windows10 install wim on the Recovery partition - not sure.
If your machine is running fine, it's easier to leave it be. ... it's only 24 GB (only he says)
Let me know if you want to play with the ReadyCache/Boot/Recovery possibilities. It takes a bit of time doing it on a forum ...
I'd need to know the exact model of you Asus to go any further ... and answers to questions I haven't yet asked
UX501 | UX305 | UX303| UX301 | ?something else?
Also, it would be helpful to know what Win10 has configured for the Recovery partition:

Post the results
It's also VERY useful to members to have details on your machine in your TenForums > Profile > system spec.
The easiest way to do this is to use the information from a PUBLISHED Speccy report.
See: Speccy - Publish Snapshot of your System Specs
Post the link to the report that Speccy gives you and also open the Speccy link.
Then click here to view your System Specs on this forum.
When you have both windows open, put them side-by-side and simply copy the information, field by field, from the Speccy report to your System Specs.
- In the System Manufacturer/Model Number field, manually type Desktop or Laptop adding it to the information already in the field. The specific model number is important - there are often many models of a given series.
For example, my machine is a HP Pavilion dv6, but there are tens of the dv6 series, so dv6-6c10us is the specific model.
- Specify Custom Build as the manufacturer if it is not an OEM machine.
- Don't forget to include the bitdepth of your Os (32-bit or 64-bit)
