Вечер добрый!

Что-то меня достали тормоза на моём ноуте. Вроде машинка не сильно
старая, но всё как-то медленно.

Решил первым делом посмотреть на параметры винчестера.

[denis@ogion ~]$ sudo -H hdparm -tT /dev/hda

/dev/hda:
 Timing cached reads:   224 MB in  2.04 seconds = 110.01 MB/sec
 Timing buffered disk reads:   54 MB in  3.05 seconds =  17.69 MB/sec


[denis@ogion ~]$ sudo -H hdparm -iIv /dev/hda

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 65535/16/63, sectors = 78140160, start = 0

        R/W multiple sector transfer: Max = 16  Current = 16
        Advanced power management level: 128 (0x80)
        Recommended acoustic management value: 254, current value: 254
        DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 udma5
             Cycle time: min=120ns recommended=120ns
        PIO: pio0 pio1 pio2 pio3 pio4
             Cycle time: no flow control=240ns  IORDY flow control=120ns
...

На сколько я понял, включен режим udma2. У меня такой вопрос, можно ли
для этого винчестера включить более быстрый режим, или udma2 для него
потолок? И можно ли включть 32-bit для IO_support, или не стоит?

Всего доброго,

Денис.
