I tried to re-create the RAID with 128KB stripes. /dev/sdc: pdc, "pdc_ghaehjgj-0", stripe, ok, 1759414272 sectors, data@ 0 /dev/sde: pdc, "pdc_ghaehjgj-1", stripe, ok, 1759414272 sectors, data@ 0 /dev/sdd: pdc, "pdc_ghaehjgj-0", stripe, ok, 1759414272 sectors, data@ 0 /dev/sdf: pdc, "pdc_ghaehjgj-1", stripe, ok, 1759414272 sectors, data@ 0 IO 131072 / 262144 It's still nowhere near expected results. Re-created as RAID0. 2742690304 sectors, roughly 1.3TB instead of 8. Oddly enough, the RAID controller detects as follows in lspci: 00:11.0 RAID bus controller: Advanced Micro Devices, Inc.
