The video opens with Linus introducing a new 24‑drive SSD storage server, highlighting the need for high‑performance, fault‑tolerant storage for video editing and 4K workflows. He explains the choice of Kingston KC310 drives, the Corsair HX 1200i power supply, and the LSI 9271 8‑port RAID cards that will host the 24 SSDs. Linus then walks through the physical installation of the drives on sleds, the cabling to the SFF‑887 connectors, and the mounting of the RAID cards in the PCI‑Express 3.x slots. He configures the arrays in Windows Disk Management, first creating eight‑drive RAID‑0 arrays on each card, then combining them into a RAID‑5 stripe to provide redundancy and a spare drive. In the second half, Linus benchmarks the array, reporting read speeds of over 5.12 GB/s and write speeds that exceed the 2 × 1 GB network interface. He discusses the impact of caching, the importance of a UPS for the RAID cards, and the expected throughput when multiple users write large files. The video concludes with a brief recap of the hardware, a call to action for viewers to comment and subscribe, and a nod to the sponsor link for Linus Tech Tips. Overall, the video delivers a clear, step‑by‑step guide to building a high‑capacity SSD RAID server, with practical performance data and a friendly tone that keeps the audience engaged.
Viewers praised the video for its clear explanations and practical benchmarks.

Questions answered
- What is the total capacity of the SSD array built in the video?
- The array consists of 24 Kingston KC310 1 TB drives, giving a total capacity of 24 TB.
- Which RAID level was used for the array?
- Linus configures the drives in RAID‑0 on each of the three LSI 9271 cards, then stripes the three RAID‑0 arrays together in software to create a RAID‑5 configuration.
- What performance metrics were reported for the array?
- Read speeds exceed 5.12 GB/s and write speeds are over 5 GB/s, with the array able to handle multiple users writing large files simultaneously.
- How does the server handle network traffic?
- The server is backed up nightly over a 2 × 1 GB network interface, and the RAID‑5 stripe can saturate the network with excess throughput of more than 5 GB/s for small transactions.
