我買了一顆新的wd640 aaks用了一陣子系統是ubuntu 8.04的我上網查了一下 ST3640323AS Seagate 梭魚11代緩衝區32MB 容量640GB(實際可用596.17GB) 單碟320GB hdparam的測試結果： Timing cached reads: 7798 MB in 2.00 seconds = 3901.91 MB/sec Timing buffered disk reads: 320 MB in 3.02 seconds = 106.06 MB/sec 這是別人seagate的數據照到理來說應不會差距多大但我跑的結果是 Timing cached reads: 550 MB in 2.00 seconds = 274.57 MB/sec Timing buffered disk reads: 16 MB in 3.12 seconds = 5.12 MB/sec 我有三顆硬碟只有這顆sata 不知是不是這原因另兩顆cached reads都差不多但第二項數據至少都50起跳且是四年前的硬碟我的主機板是kt880-l(via 880晶片組) 不知有解嗎? 搞老半天總覺的是硬碟效能沒被發揮到複製檔案到這個硬碟就很痛苦! 特請求救 -i的也列一下三顆硬碟都有怪現象 /dev/sdc: IO_support = 0 (default) 16-bit) HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device HDIO_GET_DMA failed: Inappropriate ioctl for device HDIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device readonly = 0 (off) readahead = 256 (on) geometry = 12289/255/63, sectors = 1250263728, start = 0 中間那三項都是一樣出現failed -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 123.204.92.180
