Brian invites Allyn Malventano to join him in the lab for an often candid discussion of SSD technology, specifically PCIe Gen 5.0. Allyn is, as he puts it, a jack-of-all-trades-storage, Storage Technical Analyst. Although Allyn works for Intel, he is tasked with understanding all vendor equipment related to storage and servers.
Allyn brought along a system for a live demo analog with Samsung’s Gen5 PM1743 SSDs. The discussion is mostly around SSDs, performance, and configuration requirements. It is a lively discussion about how to get the most from your existing system and what to look for moving forward.
