Захотел сделать хранилку на теробайт из старого компа(второй пень), все встало хорошо, единственное что смущает - скорость чтения с диска: dd с раздела в /dev/null идёт со скоростью 10 мегов в секунду при этом загрузка проца 60% из них 55% system, диски быстрые, хотелось бы хотябы 30 при ATA66 это вроде как вполне возможно.

Что можно сделать?
