Timeouts on modern SATA disks usually indicate hardware problem.
* unstable power supply (this is quite common)
* faulty cable or poorly seated connectors
* faulty drive or controller (seems rare)
Please apply common hardware debugging method - isolate problem by
changing configuration piece-by-piece and finding out to which component
the error actually belongs to.
