Are there reports on its proven quality, whether SMART works with smartmontools, and if/how hotplug/hot-add/hot-swap/hot-remove is handled? I.e. can we run a 4 disk software RAID-5 from this controller and use hot-swap and SMART reliably? Also, I noticed there is no driver yet for the libata framework by Jeff Garzik. Jeff reported to work on hotswap RSN so maybe a libata driver for Marvell is the way to go? Given the host controller chip datasheet, would it be hard to add a libata driver (what are the hurdles to take?) Regards, Leon.
