Hi all, I have been looking at the speeds of the disks in some of the threads lately. I noticed that mine is a lot slower than most. I have attached some info. Is my disk running as optimally as it can or is there some more tweaking I can do to improve performance?
laptop root # hdparm -tT /dev/hda
/dev/hda:
Timing buffer-cache reads: 644 MB in 2.00 seconds = 322.00 MB/sec
Timing buffered disk reads: 22 MB in 3.25 seconds = 6.77 MB/sec
laptop root # hdparm /dev/hda
/dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 2432/255/63, sectors = 39070080, start = 0
laptop root # hdparm -i /dev/hda
/dev/hda:
Model=HITACHI_DK23CA-20, FwRev=00H1A0J1, SerialNo=12N68B
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
RawCHS=16383/16/63, TrkSize=36477, SectSize=579, ECCbytes=4
BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=39070080
IORDY=yes, tPIO={min:400,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: sdma0 sdma1 sdma2 mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 *udma2 udma3 udma4 udma5
AdvancedPM=yes: mode=0x80 (128) WriteCache=enabled
Drive conforms to: ATA/ATAPI-5 T13 1321D revision 3:
* signifies the current active mode
What other hdparm flags can I _safely_ use, I don't want to trash my
disk.
Thanks and Regards
Craig
