无所谓了,我这里还有个hdc,和hda一模一样的型号,大小,hdparm -i显示这样
/dev/hdc:
Model=Maxtor 6E030L0, FwRev=NAR61590, SerialNo=E11B4Q0E
Config={ Fixed }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57
BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=60058656
IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2
AdvancedPM=yes: disabled (255) WriteCache=enabled
Drive conforms to: (null): 1 2 3 4 5 6 7
根本看不到UDMA几,hda倒是对的(和你的一样)..
不过,不用管参数,用hdparm -Tt /dev/hda1之类测测性能,没什么问题就是了。我这里hda和hdc的表现就几乎一样,所以更相信这个结果而不是hdparm -i的显示
fancyworld root # hdparm -Tt /dev/hdc5
/dev/hdc5:
Timing buffer-cache reads: 128 MB in 0.82 seconds =155.34 MB/sec
Timing buffered disk reads: 64 MB in 1.37 seconds = 46.68 MB/sec
fancyworld root # hdparm -Tt /dev/hda5
/dev/hda5:
Timing buffer-cache reads: 128 MB in 0.84 seconds =153.11 MB/sec
Timing buffered disk reads: 64 MB in 1.29 seconds = 49.61 MB/sec |
