optimizing the hard drive?
How can I optimize hard drive access? Please tell me I don't
have to try one million random combinations of the various flags
to hdparm. Or is the kernel doing the right thing already?
Possibly relevant bits from dmesg:
VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0xe000-0xe007, BIOS settings: hda:DMA,
hdb:DMA
ide1: BM-DMA at 0xe008-0xe00f, BIOS settings: hdc:DMA,
hdd:DMA
hda: WDC WD102BA, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: WDC WD102BA, 9779MB w/2048kB Cache, CHS=1246/255/63
Partition check:
hda: hda1 hda2 < hda5 hda6 hda7 hda8 hda9 >
This drive is supposedly 7200 rpm (according to my receipt).
Can anyone confirm this? Shouldn't that make it blazing fast?
Hdparm -tT says:
/dev/hda:
Timing buffer-cache reads: 128 MB in 2.08 seconds = 61.54
MB/sec
Timing buffered disk reads: 64 MB in 22.28 seconds = 2.87
MB/sec
