The video discusses methods to safeguard data on a Synology NAS by utilizing SMART (Self-Monitoring, Analysis, and Reporting Technology) tests to identify potential hard drive failures. These tests, which assess attributes like age, wear, bad sectors, and overall health, are crucial in preventing data loss. Upcoming DSM-7 features enhance data protection by facilitating cloning without RAID rebuilding. The speaker emphasizes using Btrfs file systems with checksums and redundant RAID for optimal data integrity.
Synology categorizes drive health into 'Good,' 'Warning,' and 'Damage' thresholds to help users decide when to replace drives. The video provides guidance on running SMART tests via Synology DSM's Storage Manager, detailing how to view health information and specific diagnostics for Seagate IronWolf drives. Two types of SMART tests are recommended: quick tests for rapid feedback and extended tests for thorough checks. Scheduling these tests, especially extended ones weekly and quick ones nightly, and configuring email alerts for bad sectors and monthly reports are advised to ensure early issue detection and efficient drive management.

In this part of the video, the speaker discusses how to protect data on a Synology NAS by identifying potential hard drive failures through SMART tests. The upcoming DSM-7 feature will allow data cloning without RAID rebuilding, making the process more efficient. The speaker explains that SMART tests, which are self-assessments done by hard drives, provide crucial information such as the age and wear of the drive, and the presence of bad sectors. These tests help in detecting and handling corrupted data areas, preventing potential data loss. The importance of using a file system like Btrfs with checksums and redundant RAID is emphasized to ensure data integrity and facilitate the swift replacement of failing hard drives.

In this part of the video, the speaker explains how Synology tracks hard drive health using SMART tests, which monitor various drive attributes. Synology can alert users via email when a bad sector is detected. If users observe increasing bad sectors, they should replace the drive promptly as hard drives can fail suddenly. Synology categorizes drive health into three thresholds: ‘Good,’ ‘Warning,’ and ‘Damage,’ where ‘Good’ indicates no issues, ‘Warning’ suggests ordering a replacement soon, and ‘Damage’ indicates untrustworthy data. The video instructs users on running SMART tests in Synology DSM by navigating to the Storage Manager, where they can view detailed health information, including bad sectors, uptime, reconnected times, and temperature. It also covers the specialized health integration for Seagate IronWolf drives, which provides additional diagnostic codes.

In this part of the video, the speaker explains the different types of SMART (Self-Monitoring, Analysis, and Reporting Technology) tests for drives: a quick test and an extended test. The quick test is brief and minimally disruptive, providing rapid feedback, while the extended test thoroughly checks the entire drive. The speaker demonstrates how to schedule these tests and view the results, including key attributes such as read rates and usage. The values reported include the most recent reading, the worst recorded value, and the error threshold. The history of past tests is also accessible, showing details like the number of reconnections and bad sectors. Finally, the speaker shows how to set up the test scheduler for automated testing, emphasizing its ease of use and importance for managing multiple drives.

In this part of the video, the speaker explains how to schedule and manage SMART tests for drives on a Synology NAS. Users have the option to run quick or extended tests and can apply these tests to all or selected drives. The speaker recommends scheduling extended tests weekly at midnight to avoid NAS slowdowns and suggests running quick tests nightly for early detection of issues. Additionally, users can configure email notifications for monthly hard drive reports and bad sector warnings. The importance of updating the SMART database for newer drives is also highlighted, though it is typically not necessary to do often. The speaker concludes by emphasizing the value of SMART tests in preventing hard drive failures and encourages users to set them up for added protection.
