109 109  A fast SLOG can provide amazing benefits for applications that need lower latencies on synchronous transactions. This works well for database servers or other applications that are more time sensitive. However, there is increased cost for adding a SLOG to your pool. The battery-backed DRAM chips are very, very expensive. Usually on the order of $2,500 per 8 GB of DDR3 DIMMs, where a 40 GB MLC SSD can cost you only $100, and a 600 GB 15k SAS drive is $200. Again though, capacity really isn't an issue, while performance is. I would go for faster IOPS on the SSD, and a smaller capacity. Unless you want to partition it, and share the L2ARC on the same drive, which is a great idea, and something I'll cover in the next post.
