this is an awesome video, thank you so so much I really appreciate it because you explained everything clearly and without fluff. much appreciated! so, I have a question: I have a lot of hard drives that I filled up over the years and now I want a storage solution where I can put all of those drives' data into for backup because I feel like it's really risky having different hard drives in case one of them breaks as they get old or through an accident or whatever. what do you suggest ??! thank you ❤️

Do you want to use those disks or just copy the data on other disks?

Question is DAS, even its a internal harddrive or any attached drive, yet if you share permission on it, anyone can access it across a network, so what makes it different to NAS? Both are accessed over the network ? Because even if a device attached to a network aka NAS and again everyone access it, in term of read right, what's the difference to DAS, because both will allow users on the network to read and right to it, where we can truly say we need NAS not DAS, because one dedicated server with loads of HARD DISKS when shared to be accessed for the network users again its the same thing, because computer is connected to a network over the ethernet.??

The main difference between DAS (Direct Attached Storage) and NAS (Network Attached Storage) lies in how they are accessed and managed, despite both being accessible over the network. 1. DAS (Direct Attached Storage): Direct Connection: DAS is physically attached to a single computer or server through interfaces like SATA, SAS, or USB. It's not designed to be a networked storage solution by default. Network Access via Sharing: Network users can access those files if a server with DAS is connected to a network and shares folders or drives. However, the key here is that the storage still depends on the host system (the server) for access control, file sharing, and performance. Usage: DAS is typically used in scenarios where storage needs are local to a single server or system. It requires manual configuration to share files across the network. 2. NAS (Network Attached Storage): Dedicated Network Storage: NAS is specifically designed to be a standalone storage device connected directly to a network. It has its own operating system and file-sharing protocols (like SMB, NFS, etc.), meaning it doesn't depend on a specific server or computer to share files. Access Control and Features: NAS devices offer built-in features for network access, including user authentication, RAID management, file permissions, and sometimes cloud integration. These features are independent of any server and are optimized for network-based access. Usage: NAS is used in environments where multiple users or devices need access to shared storage over a network, with efficient file sharing and centralized management. Key Differences: Access Dependency: DAS relies on the host server to provide network access, while NAS operates independently and directly connects to the network. Management: NAS comes with its own management tools, access controls, and features optimized for network environments, whereas DAS requires more manual configuration and lacks the network-specific features of NAS. Performance and Scalability: NAS is better suited for multiple users accessing storage over a network. DAS is more limited to the performance and scalability of the host system. When to use NAS vs DAS: DAS is good when storage is required for a single system or if network file sharing is only a secondary concern. NAS is ideal for scenarios where multiple users need access to storage across a network with better management and access controls, making it a more robust solution for shared environments. In summary, while both can allow users to access data over the network, NAS is purpose-built for that function and offers more flexibility, management, and reliability for network storage, while DAS is primarily local storage with optional network access via a server.

@@dctechnetthank you for all this info! What would you buy if you cared most about not losing data either with redundancy or other means (priority 1, 2, and 3). Distant second would transfer speed and accessibility but desired. Lastly, it would be cool if it had on/off switches to not use up the life of the drives unless you wanted them running. What would you use for both hardware and software? Scenario 1: 5x 5TB drives and Direct Connection across both a stationary Laptop and Desktop that can be moved for portability if needed but almost never moves. Scenario 2: Same but will be moved frequently to many rooms in the house or another house. Many thanks!!!
