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

An SLC SSD would probably be substansially slower than an array of MLC SSDs, and
would be likely to slow down the system for sync >writes.
