Help with Asus ROG Maximus Z790 Hero and SATA PCIe Adapter Compatibility

I have and Asus ROG Maximus Z790 Hero with a RTX 4090 covering all but the PCIEX16(G4) Slot.
I would like to add some SATA ports for more hot swap drive cadies to take 2.5" SSD's.

I have found a number of SATA PCIe Adapters on e-bay with four or six ports with the following specs and wondering if they would be suitable:-
LINK TO EBAY

Description:
SATA PCIe Adapter 6 Ports SATA III to PCI Express 3.0 X4 Controller Expansion Card
Feature:
Good reliability, availability, and high compatibility.
Able to achieve fast data transmission, up to 6Gbps transmission mechanism, save more time!
6 standard SATA III ports, which can be connected to multiple devices at the same time.
Can be used as a system disk, supports large-capacity hard disks, and can be connected to SSDs!
Highly compatible ASM processor, lower power consumption, better compatibility and faster transmission!

Specification:
Transmission rate: 6Gbps
Bus type: PCI-E X4, compatible with PCI-E X8/X16 and other interfaces
Bus speed: PCI-E 3.0
Interface: SATA III
Number of SATA interfaces: 6
Installation conditions: there must be one or more free PCI-E slots on the motherboard

Storage temperature: -20~+40 °C
Application: desktops, workstations, servers, industrial equipment

I tried an older PCI-E to SATA Card that worked fine on my old Z390 PC and while it is recognized, the transfer rate is only about 512kb/s instead of the 490MB/s I got on my Z390 so that sucks.

Any advice appreciated.

Looks like I'll have to answer this myself as I purchased the card whilst waiting for an answer.

Yes it works and it gave me an extra six SATA ports on the Asus ROG Maximus Z790 Hero.
