AI OverviewEnglishEnglish

Samsung’s 960 Pro SSD delivers high‑speed storage at a third of the cost of the first boot SSD and is an order of magnitude faster in real‑world performance. Melanox Connect 4 cards, two generations old, reach 100 GB transfer speeds (~12 GB/s), enough to download Fortnite in one second. The cards use Intel controllers, plug into PCI‑Express 2.0 slots, and support Ethernet and InfiniBand; they feature QSFP+ connectors and full‑fat PCI‑Express Gen 3 × 16 links. The test setup uses an Intel 18‑core processor on a Rampage 6 Extreme motherboard with 128 GB RAM, and a second system with a 16‑core 7960X on an ASUS X299 Deluxe, also with 128 GB RAM. Four Samsung 960 Pros and four Corsair MP500s are configured in RAID 0 for NVMe storage. Windows Server 2016 is used for the OS, and the cards are paired with 100 GB passive copper direct‑attach cables (≈$60 for a 3 m cable). Benchmarks show 40 GB files transfer at ~2 GB/s from NVMe to RAM disk, rising to ~4 GB/s, then ~10 GB/s, demonstrating effective RDMA over converged Ethernet (ROCE). The setup supports lossless network transfers with minimal CPU overhead, achieving near‑zero CPU usage during transfers. The video concludes with a call for feedback on deploying this technology in real‑world scenarios. Join the forum and wear that shirt.

The comment thread shows a lively discussion about transfer speeds and hardware choices, with several users praising the 100 GB/s transfer claim and asking for more details on the testbench. A few commenters note the importance of dual‑core setups and the potential for SLI, while others joke about the “dual‑citizen” nature of the build. Overall sentiment is positive, with high‑like counts and multiple replies indicating strong engagement. The community also references real‑world scenarios such as downloading large games and moving data between servers, reinforcing the relevance of the video’s performance claims.
