Как я понимаю непрерывный трансфер должен быть порядка 40-50Мb/s. Хотя hdparm дает следующее: #hdparm -tT /dev/sda /dev/sda: Timing buffer-cache reads: 492 MB in 2.00 seconds = 246.00 MB/sec Timing buffered disk reads: 26 MB in 3.16 seconds = 8.23 MB/sec Помогите разобраться с этой проблемой, или наставте на путь истинный. P.S. Кусок dmesg в атаче. -- Best regards, Alexey [-- Attachment #2: dmesg. --] [-- Type: application/octet-stream, Size: 2118 bytes --]
