Hi,
Sorry If it has been asked before I am new to RAID controllers and I am planning to buy one.

This one in particular. However, In India we do not have hardware availability like US so I am bit confused if it is the right one or not. Also, I would like to know when buying one of these what things you should be looking at.
I have only 4 slots on my MOBO. and all of them are utilized. So looking for expansion cards.
Hardware:
intel i5-6402p
Asus Bx-150M Motherboard
16 GB DDR3 RAM
2x3TB Mirror
