- Special NASWare firmware
- Low power consumption
- Quiet operation
- Optimised and certified for NAS use
- Mediocre transfer rates
The Western Digital Red 4TB (WD40EFRX) is specially designed for NAS use. In testing, it shows only average performance, but low power consumption. It also remains pleasantly quiet both at rest and in operation. In combination with the huge capacity and the low price per GByte, the Red is a good choice for NAS users.
- Particularly energy-saving
- Very quiet when idling and accessing
- leisurely pace of work
With its fair price and quiet operation, the WD is a rather slow hard drive, but it is convincing in terms of power consumption and has a good price-performance ratio. So if you can afford to compromise on speed, this is a good choice.
