I noticed that my Supertalent MEs were experiencing massive speed loss in tests when file size fell under 32k and set my strip size accordingly. If I remember right I went to 64k. When I cloned my OS X drive I got something like 30 MB/s average and initally it was down at 10. Later when I was copying Gigabyte files (Winclone images) it got up to 110 MB/s peak value. I have no simmillar info for my new Intels 2nd gen. So provisionally I'll be using a simillar value. I also noticed that Windows disk management program uses 4128k as a standard which appears massive and probably usefull for HDDs. Could somebody with more in depth knowledge advise a rational choice for OS x and Windows for different SSDs?
