I have already 2 msata ssd's and then one 2.5 ssd for the OS. (p157sm)
In addition I have 1 WD mobile blue and I have now ordered 1 more for placing in a caddy (optical bay).
The plan is to set up the two wd blue's in "hardware" raid 0 through the bios. I am already running in uefi mode, and I must change my sata mode in bios to raid mode.
But what exactly is the procedure following the settings in bios ? I do not want to touch my boot configuration and I am afraid of proceeding before I am certain of what to do.
As for the upcoming two Blue's in raid 0, I back up every day and I am not worried about loosing my data - at all.
If anyone could help me out I would be very appreciativeThanx!

Honestly I would not mess with BIOS fakeraid unless you are using the drives to boot.
Use disk management to set up a striped volume in Windows for the two drives. Here's a video, it doesn't get any easier, just make sure to use GPT format instead of MBR.

Using software RAID, you don't have to change anything in the BIOS and Windows manages the volume. You also avoid the annoyances and blue screens that Intel's Rapid Storage Technology drivers can cause and the performance difference isn't really there (IRST is still software RAID after all). -
Great
Thank you very much ! All I am really interested in is higher sequential speed. Much obliged.

You would still need the bios switched to raid mode and then you would need to edit your windows install to run in raid mode rather than AHCI which would require some registry changes.

Thanx to both of you
What is the difference between using disk management for a striped drive & making a simple volume or raid equivalent in "storage spaces" ? I have reinitialized both drives to GPT, of course now they are empty, and should I just try out both solutions for speed and usability you think ? Or is one clearly preferable over the other ?
Update: Ok, so I set up a striped volume in disk management with 2 x wd blue 1tb, and I turned off buffer flushing. I get sequentials now around ~200MB/s. Since larger type incompressible files are primarily my daily point of use for the disks I am really very happy with that, since I only saw around and below 100 MB/s for a single disk. That reminds me - I have to change my signature....
2 Update: Picked up some pointers here and there... Found an estimated drop-off point for read/write max performance for my disks, made a striped volume of 400 GB for speed and made a spanned volume for the rest. That way I can extend that volume or shrink it if I choose to, and play around to find my sweet spot for performance on the striped volume.
The problem here seemed to be that certain parts of the platters give lower write-speeds in particular, and also considering these hdd's have three platters per disk. So writing 200GB to each disk for a combined 400GB makes up a fast-transfer alternative for me for now. It seems to work well, the sequentials do not seem to drop off now, besides on the spanned volume. That is a bit irritating though, because I now use that spanned volume for temporary backup of my virtual machine - msata ssd's and iiiit iiiiss sloooooooow. I did a couple of backup tests to the striped volume, and that was a totally different story... Oh well
Non - OS raid 0
