Hard disk drive is a common component in both DIY NAS and off shelve NAS. Typically, the price of off shelve NAS do not include HDDs. For a clear comparison, I will not include the cost of HDDs in my NAS build.
The Three Musketeers
I planned to start with 3x 2TB HDDs and scale to 6 in total. If the NAS enclosure also offers hot swappable features, upgrading or replacing HDDs will be a walk in the park. Master C suggested Western Digital RED HDDs while Ah Kim ambitiously recommended 4TB drives. On a tight shoestring budget, I prefer to start modestly and expand in future. Below are the three musketeers used in my setup:
| QTY | Manufactuer | Capacity | Model | Specs |
| 1 | WD Green | 2TB | WD20EARS-00S8B1 | 64MB Cache / 5400RPM |
| 1 | Seagate Barracuda Green | 2TB | ST2000DL003 9VT-166 | 64MB Cache / 5900RPM |
| 1 | Samsung EcoGreen F4 (Barracuda Green) | 2TB | ST2000DL004 | 32MB Cache / 5400RPM |
The WD Green is recycled from my current desktop while I purchased the Seagate & Samsung drives from IT Garage sales. Both the Seagate & Samsung are fresh RMA drives, as good as new. I intently picked 3 HDDs of different makes; which one do you think will die first?
