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

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

Direct-attached storage (DAS) is digital storage directly attached to the computer accessing it, as opposed to storage accessed over a computer network (i.e. network-attached storage). Examples of DAS include hard drives, solid-state drives, optical disc 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 key difference between DAS and NAS is that DAS storage is only directly accessible from the host to which the DAS is attached. A DAS does not incorporate any network hardware and related operating environment to provide a facility to share storage resources independently. The storage presented by a DAS to a connected host can of course be shared by that host. A SAN (storage area network) has more in common with a DAS than a NAS with the key difference being that DAS is a 1:1 relationship between storage and host whereas SAN is many to many.

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