go with the 3 drives. It offers more space for a lower price.

Hello,

I am going to build my first NAS soon, probably using Unraid.

I could either buy 3 x 4TB drives and use one as parity, or 2 x 6TB drives (one in mirror).

it is about £20 more expensive to use the two drives instead of three.

the other difference is that the 3 x 4tb drives are at 5.9k RPM, whilst the 6TB are at 7.2K.

I'm planning to use this as a server to store backups so speed is not necessarily a concern, while noise is.

is there an advantage to using three or only using two?

 

thanks. :D

the slower drives are going to be quieter can you put the 3 drives in a raid 5?

unraid doesn't use traditional raid apparently, but yes i can do the equivalent

yeah, with what was mentioned either 3 4TBs or two 6TBs mirrored, the mirrored is going to be 6TBs (obviously less after formating ect.) with my rough calculation 3 4TBs are going to be around 7TBs (this is based on rough calculation of my raid 5 setup)

Yep! It is the cheapest out there, the Seagate Constellation also has a low $/gb and it is worth to consider as it was the NAS drives product line from Seagate.
