Core Storage bound volumes are not striped and they are not RAID either. Also unlike RAID, Fusion Drives are tiered Storage that operates below the file level. Keep squirming if you feel you must though. > Since Fusion is host based disk management Nonsense. Core Storage presents a single volume to the system. > The Ars articles seem to conclude it is block based As do Apple's own tools referenced by the Ars Technical articles. There's a reason Apple named Core Storage operations related to Fusion Drives RdChunkCS, WrChunkCS: because data is moved at the block (chunk) level, which is easily verified by Ars and others simply by watching the activity during file access. > but I am not > convinced their metrics are correct.

Not when Apples own tools (fs_usage etc) show the data being read and written on the SSD itself, nope. That's also mentioned in the Ars Technical articles. -- E-mail sent to this address may be devoured by my ravenous SPAM filter. I often ignore posts from Google. Use a real news client instead. JR
