Storage Server Capable of Raid 6

[Christy007]

Budget (including currency): ₹150000

Country: India

Games, programs or workloads that it will be used for: As a storage server.

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 

My total Budget is 150000 INR

4x 4TB Seagate Barracuda 6 Gb/s 5400 RPM (on amazon 4*8199= 32796)

2x 4TB Seagate IronWolf NAS 5900RPM (on amazon 2*12399= 24798)

1x Crucial MX500 250GB (on amazon 2700)

I am thinking of running it in raid 6 Config. 4*Barracuda as normal & 2*IronWolf as Parity. I guess this config is great for redundancy & performance. Please suggest any changes if this is a bad configuration. 

The balance is ₹89706. Can i build a serve with that config with that money?

Please suggest parts for the build.
