Sata backplanes and RAID
|

| Hello
I am going to build a small RAID 6 array for my school.
I was thinking about using the SNT-2131SATA backplane for 3 disk, and
use 2 of them for a total of 6 disks.
Using 500GB disks this would give me 2TB and RAID6 for reliability.
The problem is, on the site, only raid 0 and 1 are supported.
But other vendors just put RAID support on their site, no raid levels.
My idea was that the backplane is just a extension of the sata cable,
how can it interfere with RAID operation?
Any help would be nice
Documentation about the backplane:

The documentation you pointed to clearly shows that it is a passive
backplane and is therefore entirely agnostic to whatever you choose to
do with your disks. If the vendor mentions RAID levels that's wrong.
