DiskPerf /dev/hde Device: Maxtor 91536H2 Serial Number: N200PGDD LBA 0 PIO Read Test = 5.32 MB/Sec (46.98 Seconds) LBA 1 PIO Read Test = 5.32 MB/Sec (46.99 Seconds) Outer Diameter Sequential PIO Read Test = 5.29 MB/Sec (47.24 Seconds) Inner Diameter Sequential PIO Read Test = 5.29 MB/Sec (47.28 Seconds) LBA 1 PIO Write Test = 5.22 MB/Sec (47.86 Seconds) Outer Diameter Sequential PIO Write Test = 5.21 MB/Sec (48.02 Seconds) Inner Diameter Sequential PIO Write Test = 5.22 MB/Sec (47.89 Seconds) LBA 0 DMA Read Test = 48.84 MB/Sec (5.12 Seconds) LBA 1 DMA Read Test = 49.07 MB/Sec (5.09 Seconds) Outer Diameter Sequential DMA Read Test = 26.53 MB/Sec (9.42 Seconds) Inner Diameter Sequential DMA Read Test = 14.68 MB/Sec (17.03 Seconds) LBA 1 DMA Write Test = 44.94 MB/Sec (5.56 Seconds) Outer Diameter Sequential DMA Write Test = 14.72 MB/Sec (16.98 Seconds) Inner Diameter Sequential DMA Write Test = 14.39 MB/Sec (17.38 Seconds)
These are all 4000 IO's at 128 blocks each or a total of 512,000 blocks. Not to bad........
Now we can profile drives to super-charge the elevator!!
One catch, these tests require a native ATA-passthough and that will not be included until 2.5.........
It is completely stable with the tested data-phases.
