Thanks for the comments. 1. From what I can tell there is at least some support for 4k disks in 5.5, at least it seems to know enough that if you create a datastore on a 4k disk it does the right thing partition wise. Installs though don't seem to work right, but like you said might be possible to manually format and install, though with I think 7+ partitions that get created on an install I don't think its worth dealing with. 2. The SAS2008 is basic, but also very cheap and actually works really well as a passthrough controller for ZFS in IT mode. I have two in this server, one in IT mode as passthrough and another in IR mode for booting and the datastore. The boot controller seems to work fairly well with a couple small SSDs in there, but not with any traditional disk drives, could be a caching issue like what you are pointing to. Re Side note: For whatever its worth I have 6 of the 3.5" Red Drives hooked up as ZFS raid-z2 setup and haven't had any issues with them over the last 6+ months. For a home server the price + 3 year warranty was enough to make me give them a try. For something more mission critical I would've gone with something else.
