[OpenIndiana-discuss] Raid type selection for large # of ssds

[Sebastian Gabler]

I should have pointed out better that my intention is to use a ZIL SSD 
in context with "spinning rust", not with MLC SSDs behind them. In 
general, SLCs are more suitable as a ZIL because they can sustain write 
rates more continuously, for a wider variety of workloads, and sustain 
to writes more endurably, plus typically perform at higher IOps rates 
than an MLC SSD of the same size. BR Sebastian
