RAID01/RAID10 with two M500 960GB SSDs and singe 2TB HDD

Hi, I've recently sold my laptop and recovered my 960gb M500 ssd from it. I also have a lot of budget left over from cooling as I went with TEC instead of pre-built compressor phase cooler which saved me around a grand.

There is a guy locally who wants to sell his 960GB M500 SSD bought in early january for 400$. I am tempted to have a RAID01/10 where I have two SSDs in RAID0 and the 2tb HDD to mirror the raid0 array.
Raid1[Raid0(SSD,SSD),HDD] Like this.
My motherboard is X99 Extreme11 from Asrock. I have more than enough Sata3 ports.

My question is does the motherboard/chipset support this kind of raid? Also, I heard that TRIM with Raid0 is supported in most motherboards now, is the TRIM still supported when going with this kind of configuration? Will the SSDs be bottle-necked by the slow HDD mirroring it-am I just better off going with RAID0 and then using the HDD as a scheduled backup drive?

Any insight/warning/suggestion on this configuration would be wonderful.
Thank you for your time.

You don't want to mirror a HDD with an SSD. You might still get the read benefits of the SSDs, but you'll lose all the write performance as the system (and you SSDs) will be waiting on the HDD to complete write commands.

If you're worried about losing data, why don't you use the HDD as a backup drive. Have your 2TB Raid0 array with your M500s, and setup a daily backup (or whatever) to the HDD. You get all the performance benefits of SSDs, and most of the protection against a failed disk (you would lose data since your last backup), but also the benefits of backup such as accidental file deletion, where RAID doesn't help you.

That sounds like a bad idea, on multiple levels.

Yes, sounds like RAIDing SSD and HDD seems bad idea overall. I will go with scheduled backup instead.
