Exact SSD specs

[DanielMcc]

Well it wouldn't let me select any other options for this conversation... I have a pavilion tp01-2227c. I am wanting to upgrade my SSD I have been told conflicting things about this. Some have one slot and it's what is being used some say I have an extra M.2 along with the SSD being used. How many are there really? And exactly what kind am I needing to replace it with? Yes I understand I could simply open it and look. However I am not currently around and my wife laughed at me when I asked her to open it for me in video call. So as to me not getting laughed at again I am turning it over to you for assistance

According to the parts list for your PC, it comes with a HP 'Stark' motherboard, which has an Intel H570 chipset.

Motherboard specs:

There is one M.2 slot for a M.2 2280 NVMe SSD which is occupied, and one M.2 2230 slot for a Wi-Fi card which is occupied.

The M.2 'Expansion Slot' is kind of a misnomer.

There aren't extra slots for another SSD and Wi-Fi card.

When you look at the motherboard specs, you have to assume that you are looking at a barebones motherboard with nothing installed.

So, if you need more NVMe storage you will have to remove the existing 512 GB drive and install one having a greater storage capacity.

According to the chipset specs from Intel the SSD PCIe slot is PCIe Gen 3.0.

A PCIe Gen 4.0 SSD will work fine but it will not run at its maximum advertised read/write speeds from the Gen 3 slot.

You will probably find it easier and less expensive to buy a Gen 4.0 NVMe SSD than to buy another PCIe Gen 3.0 SSD.
