What the hell is SATA Express and how do I connect a normal SATA drive to it?

So I had a ASRock Z87 Professional motherboard which had 10 SATA ports on it that unfortunately just shit the bed.

Finding a replacement Z87 was too difficult so I replaced it with a Z97 Professional.

Problem is, I was running ten hard drives in my machine using all 10 SATA ports on the Z87 Professional.

The Z97 Professional is largely identical to the Z87 model but instead of 10 SATA ports it has 8 SATA ports with these two little extra "SATA Express" ports.

What the hell is this and how do I find a cable that allows me to connect one end to the SATA Express port and the other end to my regular SATA hard drives? I tried searching for a "SATA Express to SATA adapter" but I just got a bunch of stuff that didn't look like what I need.

Wiki says this:
SATA Express (abbreviated from Serial ATA Express and sometimes unofficially shortened to SATAe) is a computer bus interface that supports both Serial ATA (SATA) and PCI Express (PCIe) storage devices, initially standardized in the SATA 3.2 specification.[1] The SATA Express connector used on the host side is backward compatible with the standard 3.5-inch SATA data connector,[2] while it also provides multiple PCI Express lanes as a pure PCI Express connection to the storage device.

This is also from this page: https://en.wikipedia.org/wiki/SATA_Express

Mechanically, connectors on the host side retain their backward compatibility in a way similar to how USB 3.0 does it – the new host-side SATA Express connector is made by "stacking" an additional connector on top of two legacy 3.5-inch SATA data connectors, which are regular SATA 3.0 (6 Gbit/s) ports that can accept legacy SATA devices.

There is a picture on that page that for some reason i cant link too, but the picture shows 2 regular sata cables plugged into the 2 plugs on the sata express ports.
 
Take SATA cable, plug one end into drive, plug other end into motherboard. Done.
 
Your board only has 8 ports. Each Sata Express port only allows for 2 regular sata devices to be plugged into it. The Sata Express device will occupy both sata ports, and the third sata-express specific port, thereby taking up the entire row.

Unlike Z87, you need to move up to the Z97 Deluxe to regain those extra 2 ports for 10 total.
 
Oh ffs. Now I get it. Stupid ASRock.

This was almost the perfect Z97 motherboard too. Now I have two useless ports when they could've just left it at a 10 SATA port configuration like the Z87 Professional.

Guess I'll go throw two of these hard drives into the basement server.
