Интересует результаты UnixBench, правильно ли настроен мой HD?

Question 1

Я скачал UnixBench 5.1.3 и запустил его как на моем старом Dell 4600, так и на моем новом Gateway SX2800. С 2,4 ГГц P4 Dell подвергается тестированию процессором на шлюзе с четырехъядерным процессором Q8200 с частотой 2,3 ГГц.

Удивительно, что старый Dell с диском Maxtor STM3200820A (ATA) намного быстрее, чем новый шлюз с WDC WD6400AAKS-22A7B2 (SATA) при тестировании файлов. Например:

File Copy 1024 maxflocks bufsize 2000:

 181258.6 (Dell, Centos 6.5)
 16985.0 (Gateway, Ubuntu 12.04.4 LTS)

Question 2

Хорошо, я понял это. Это - "зашифрованный корневой каталог" налог.

я повторно выполнил тест на своем ноутбуке, в и из моего зашифрованного дома, и получил эти результаты:
