# hdparm -tT /dev/sdd
/dev/sdd:
Timing cached reads: 5116 MB in 2.00 seconds = 2559.79 MB/sec
Timing buffered disk reads: 244 MB in 3.00 seconds = 81.29 MB/sec
Вот я и спрашиваю, почему скорость всего 81.29 MB/sec?
При этом диск подключенный не через рейд а на прямую в материнку показывает
/dev/sda:
Timing cached reads: 4914 MB in 2.00 seconds = 2458.82 MB/sec
Timing buffered disk reads: 326 MB in 3.00 seconds = 108.62 MB/sec
