Скачать или смотреть DAS NAS SAN : Understanding Data Storage Systems

Every single second, the world generates hundreds of terabytes of new data — photos, videos, messages, research, transactions, and AI-generated content.

But where does all this data actually get stored?

In this video, we’ll explore the three main types of data storage systems used today — DAS (Direct-Attached Storage), NAS (Network-Attached Storage), and SAN (Storage Area Network).

We’ll look at how data flows from the application layer all the way down to the drives, and understand:

How DAS connects directly to a computer’s motherboard (SATA, NVMe).

How NAS makes data accessible over a local network using file-level access.

How SAN enables enterprise-level block storage over fiber channel or high-speed Ethernet.

You’ll see real hardware examples — from SATA drives and SSDs to enterprise-grade NAS and SAN racks — along with block diagrams that illustrate how data travels through each storage type (the software stack).
