The video discusses the dropping prices of SSDs compared to traditional hard drives, highlighting advantages like faster random file access and improved performance. It emphasizes that SSDs are becoming more affordable, making all SSD NAS setups feasible for users with moderate storage needs. The speaker compares SATA SSDs and NVMe SSDs, noting differences in performance and price. While hard drives excel in storage capacity, SSDs offer faster speeds and benefits for virtual machines. The video also touches on considerations for RAID configurations, SSD longevity, and the benefits of SSDs in NAS setups like lower power draw and quick installation. The transition to all SSD NAS setups is seen as more viable as technology advances, but cost and speed constraints remain a concern for very high-capacity SSDs.

In this segment of the video, the speaker discusses the dropping prices of SSDs, highlighting that you can now buy a one terabyte SATA SSD for $60 and a four terabyte SATA SSD for $220. The video presents the debate on whether to use traditional hard drives or SSDs, emphasizing the advantages of SSDs for specific use cases, particularly in random file access where SSDs significantly outperform hard drives. The speaker also mentions the differences between SATA SSDs and NVMe SSDs, focusing on performance, price, and hot-swapping capabilities. The increased affordability of SSDs makes deploying all SSD NAS systems feasible for many users, especially for those with moderate storage needs.

In this segment of the video, the speaker emphasizes the significant performance difference between using a SATA SSD and a mechanical hard drive in a NAS system. SSDs offer about a hundred times faster random read and write speeds compared to hard drives, leading to faster file access and operations, especially in scenarios with multiple users or running applications like a Synology Drive database. The speaker highlights the benefits of all SSD NAS setups for virtual machines, noting that SSDs excel in handling random file access and updates much faster than traditional hard drives. While hard drives currently excel in storage capacity, SSDs are gradually improving, although consumer-level adoption of very high-capacity SSDs is not yet feasible due to cost and speed constraints.

In this segment of the video, the speaker discusses the current capacities of hard drives and SSDs, highlighting that the highest hard drive capacity available is 22 terabytes and the maximum SATA SSD capacity is eight terabytes. The speaker explains that QLC SSDs store more data on each cell, but this can lead to longer access times and reduced lifespan. They compare the pricing and storage capacity of hard drives versus SSDs, noting that hard drives are more cost-effective and offer greater overall capacity. The speaker also addresses concerns about SSD longevity, stating that modern SSDs have significantly increased data storage capabilities and are unlikely to fail unless mismanaged. RAID rebuilds on SSDs are noted to be faster due to improved random access times.
00:09:00
In this segment of the video, the speaker discusses the importance of considering terabytes written when using SATA hard drives in RAID configurations. They suggest multiplying the terabytes written value by the number of drives in the array to determine overall endurance. The benefits of SSDs over HDDs are highlighted, including lower power draw, silent operation, and easy installation in NAS units. The speaker also touches on utilizing NVMe SSD caching in NAS setups, which enables faster access to frequently accessed files by storing them on SSDs for quicker retrieval.
00:12:00
In this segment of the video, the speaker discusses the benefits of using SSDs over hard drives in a NAS setup. SSDs provide almost instant returns, allowing for more time on sequential workflows and improved performance when installing apps. Synergy models with DSM 7.2 support using NVMe drives for storage, offering significant performance benefits, especially with large deployments of Synology Drive. However, using Synology NVMe SSDs can be costly, making it hard to justify for regular volumes. While NVMe SSDs are faster, the performance benefit may not be significant due to networking protocol overhead. One downside of using NVMe drives is the lack of hot swap ability in enterprise settings, requiring the unit to be shut down for replacement. Ultimately, the transition to all SSD NAS setups is becoming more viable as technology progresses.
