Если запускать
-device virtio-scsi-pci,id=bus-scsi0 \
-drive file=/dev/disk/by-uuid/28D5DD2B087E6B9E,format=raw,discard=unmap,if=none,id=drive0,cache=directsync,aio=threads -device scsi-hd,bus=bus-scsi0.0,drive=drive0

Вообщем то вроде перегуглил все, что мог. Скорость ужасна, судя по бенчмарку. В реале, копирование разноразмерных файлов с hdd на этот sdd началось от 120 мб\сек и опустилось до 50мб\сек (как кеш кончился).
