Anybody here uses a Seagate ST320413A with UDMA enabled on Linux? I can't seem to get anything better than 5.x from hdparm tests compared with a Samsung drive. I've already tried upgrading the firmware, interchanging the cables and drives but still no luck. Any tips? # hdparm -tT /dev/hda /dev/hdc /dev/hda: Timing buffer-cache reads: 128 MB in 3.16 seconds = 40.51 MB/sec Timing buffered disk reads: 64 MB in 11.84 seconds = 5.41 MB/sec /dev/hdc: Timing buffer-cache reads: 128 MB in 3.12 seconds = 41.03 MB/sec Timing buffered disk reads: 64 MB in 5.17 seconds = 12.38 MB/sec # dmesg | grep 'hd[a|c]: ' hda: ST320413A, ATA DISK drive hdc: SAMSUNG SV0761D, ATA DISK drive hda: 39102336 sectors (20020 MB) w/512KiB Cache, CHS=2434/255/63, UDMA(66) hdc: 14948640 sectors (7654 MB) w/434KiB Cache, CHS=14830/16/63, UDMA(66) hda: hda1 hda2 hda3 hda4 < hda5 hda6 hda7 hda8 > hdc: [PTBL] [930/255/63] hdc1 hdc2 hdc3 hdc4 < hdc5 hdc6 > -- .--.
