Hi all. I'm new in the list, this is my third message = :)
First at all, I need to say sorry if my english is not perfect. I sp= eak spanish. I post here because gentoo-user-es it's middle dead, and i= t's a great chance to practice my english :) Now, the problem.

I'm going to get a new PC with a disc SSD 120GB and= another HDD of 1TB. But in a coming future, I want to add 2 or more disks = SSD.

Mi idea now, is:

=C2=A0=C2=A0 =C2=A0Disk HHD: /dev/sda
/dev/sda1 26GB
/dev/sda2 90GB
/dev/= sda3 904GB<= /div>

=C2=A0=C2=A0 =C2=A0Disk SSD: /dev/sdb
/dev/sdb1 26GB
/dev/= sdb2 90GB
/= dev/sdb3 4G= B

And use /dev/sdb3 as swap. (I will add more with anothe= r SSD in future)
/dev/sda3 mounted in /home/user/data (to save da= ta unused)

And a RAID 1 with:
md0: sda1+= sdb1 =C2=A0 =C2=A0/
md1: sda2+sdb2 =C2=A0 =C2=A0/home

(sda1 and s= da2 will be made with the flag: write-mostly. This is useful for disks slow= er).
In a future, I'm going to add more SSD's on this RAI= D.=C2=A0My idea is the fastest I/O.

Now. My problem/question is:
Following the gentoo's doc, it says I need to put the flag --metadata=3D0.9 on = the RAID. My question is =C2=BFThis will make get off the performance?.

I only found this do= cument. This says the difference, but nothing about performance and adv= antages/disadvantages.

Another question is, =C2=BFGRUB2 still unsupporting met= adata 1.2?

In case that metadata get off performan= ce, and GRUB2 doesn't support this. =C2=BFAnyone knows how can I fix th= is to use metadata 1.2?

I don't partitioned more, because I saw this = unnecessary. I just need to separate /home in case I need to format the sys= tem. But if I need to separate /boot to make it work, I don't have prob= lems doing that.

But of course, /boot also as RAID...

=C2=BFSomebody have any ideas to make it work?

Thank you all. Bytes! ;)
