Problem is most SSD manufactures list sustained throughput with large

Who said that the slog SSD is written to in 128K chunks? That seems
wrong to me. Previously we were advised that the slog is basically
a log of uncommitted system calls so the size of the data chunks
written to the slog should be similar to the data sizes in the
system calls.
Are these not broken into recordsize chunks?
