TerraMaster D5-300C Review

Many users prefer the RAID storage configuration for their personal needs. For entry level users, simplification of such procedure is a must and therefore Terramaster offers an external solution with five (5) HDDs that can be used in RAID 0/1 configuration and also support more external HDDs that can be transferred on different personal computers. The D5-300C Direct-Attached Storage (DAS) offers many features that we will discuss in this review.

So what is DAS and how is it different from NAS / SAS? (source)

Direct-Attached Storage (DAS) is digital storage that is directly attached to the computer accessing it, as opposed to storage that is accessed through a computer network (i.e., network-attached storage). Examples of DAS are hard drives, solid state drives, optical drives, and storage on external drives. The name “DAS” is a retronym to contrast with Storage Area Network (SAN) and Network-Attached Storage (NAS).

The main difference between DAS and NAS is that DAS storage can only be accessed directly from the host that the DAS is connected to. A DAS does not include network hardware and related operating environment to provide the ability to independently share storage resources. The storage offered by a DAS to an attached host can of course be shared by that host. A SAN (Storage Area Network) has more in common with a DAS than with a NAS, with the main difference that DAS is a 1: 1 relationship between storage and host, while SAN is many to many.

DAS is also generally faster than NAS, with most networks limited to 1 Gbps, while USB 3.0, common on external drives, supports up to 5 Gbps

Exclusive 2 + 3 RAID storage

The D5-300C offers 2 + 3 RAID storage. This means that hard disk 1 and hard disk 2 can be configured as RAID 0, RAID 1 or single disk to keep your important data safe. The remaining drives 3 through 5 work as single, independent drives. This gives you maximum flexibility when using these three drives.
