About this tag
The zfs slog tag on WindowsForum.com covers the ZFS separate log device, the dedicated intent log that absorbs synchronous writes before they are committed to the main pool. Discussion here centers on Intel Optane P1600X 118GB drives used as SLOG devices in home labs, weighing their low latency, high rated endurance, and power-loss protection against modest PCIe 3.0 sequential performance and inflated used-market pricing. The thread also questions how much of the surrounding scarcity and price hype is justified. It is a practical reference for anyone evaluating whether an Optane SLOG is worth it for ZFS workloads.

    Intel Optane P1600X 118GB for ZFS SLOG: Latency, Power-Loss Protection and Used Price Reality

    Intel's Optane P1600X is a 118GB M.2 drive that is still in demand in home labs. It isn't fast by today's standards. The drive is PCIe 3.0, smaller than most modern SSDs, and any current NVMe will beat it in sequential transfers. Home lab builders want it for other reasons: very low latency...
