I'll buy Asus Z97-A (I wanted Asrock Z97-EXTREME4 But it costs $10 more and it's equal to Asus...)
Now, I'll have Sata Express ... can i use it with my Samsung 840 evo 500gb ??

SATA Express is the replacement for SATA 3.0 (which is limited to 6GB/s), and has very different connector. A single SATA Express connector is made up of two SATA 3.0 connectors and one additional connector. The two SATA 3.0 ports that make up a single SATA Express port can still be used separately, as normal, if you're not planning to plug in a SATA Express peripheral.

Your 840 EVO is a SATA 3.0 device, so will not gain any benefit from the SATA Express port (it lacks the connector to plug into it for one thing). You can still plug it into any of the SATA 3.0 ports on the motherboard, including those that form part of the SATA Express port.

Thanks very much :).
 
For all practical purposes SATA Express is 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 SExp. ASRock has a front panel USB 3.1 adapter that utilizes the SExp connectors that's included with their high-end Z170 Express 7+ motherboard and also sold separately. So who knows?

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