Im purchasing the ASRock Z97 Extreme6 LGA 1150 Intel Z97 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard and the specs say it has SATA Express capable of 10GB/s, my question is if a conventional SSD could handle that, or would it be throttled at some speed less than 10GB/s?

For all practical purposes SATA Express appears to be a dying technology (if not already dead). M.2 connectivity seems to have sounded its final death knell. It was originally designed as a SATA interface for devices that would be specifically designed for SATA Express but they never materialized since SSD manufacturers (by & large) exhibited no interest in this technology. And then came M.2...

It's conceivable I suppose that more interest may now be generated in SATA Express since ASRock has a front panel USB 3.1 adapter that utilizes the SE connectors that's included with their high-end Z170 Express 7+ motherboard and also sold separately. But I wouldn't count on it.

Anyway, a user can still utilize the SE ports for connections to...

Anyway, a user can still utilize the SE ports for connections to his/her "normal" SATA SSDs should the motherboard be equipped with SE.

You might want to do a Google search on this technology if you desire more detailed info.

The correct answer to your questions is that a standard 2.5 inch, SATA 3 6Gb/s solid stated drive would be limited to SATA 3 performance which is about 550 MB/s read and 535 MB/s write. That is the upper practical limit for a standard 2.5 inch ssd even if it is plugged into one of the two SATA ports in a motherboard's SATA Express header/port.

To the best of my knowledge there were never any SATA Express ssd's manufactured for large scale consumer use. The SATA Express standard was a last ditch effort by the international SATA organization to try and compete with newly introduced M.2 and PCIe ssd's. It was a lost cause right from the start. The new M.2 and PCIe ssd's perform better than SATA Express ever could.

Your motherboard is equipped with a M.2, 3.0 x 4, ssd header/port. You would be better off purchasing an M.2 3.0 x 4 NVMe ssd like the Samsung 950 Pro, Toshiba XG3, or OCZ RD400.
