New LSI 9200 series controllers: 6Gb/s, 2.88 GB/s seq. reads, 1.87 GB/s seq. writes

[One_Hertz]

Sorry, I was referring to HDTune in benchmark mode (which is the value that most people quote with the pretty graph), not random access mode (which is obviously random). Are you saying this is 100% random?

Yes, I believe so. Sequential access time would be like 1ms even for HDDs.
