I know the difference between SLC en MLC , but beyond that I have not the best experience with all the older SSD I have lingering about here. Most of them just "disconnect" after a while. It could be because they have exceeded their wear level and just can not write any more. But than that has occurred rather fast. So what types SSD are others using for ZIL cache what is your experience with them Thanx, --WjW
