Sorry, the previous information was incorrect. You can only create two types of RAID similar to D5-300 at the same time. (at this time, Single is also considered one type of RAID)
In the screenshot you provided, only three hard drives can be seen.
Now that you have seen the option to create RAID, please continue.

ok. can i create 2 raids 2 for hdd1 and 2(first raid 2) and for hdd 3 and 4(second raid 2) and for single hdd 5 raid JBOD or something?

So there will be three raids, it supports the use of up to two RAID at the same time.

Can i make Raid-2 with 4 HDDs( hdd 1 and 2 main and hdd 3 and 4 mirrors)?

So you were talking about RAID2? (A RAID type?) D5-300 does not support such an array type.

[stp242]

yes. sorry. about RAID1 (mirror)

[stp242]

So,Can i make Raid1(mirror) with 4 HDDs( hdd 1 and 2 main and hdd 3 and 4 mirrors)?

RAID1 is not used in this way.
If you want to make all the disks into one RAID while making two disks redundant，you can consider RAID10.
