[问题]求助！SATA硬盘传输速度超慢 仅仅28M／S

[ashunter]

恩 是的，是笔记本硬盘
查了一下这个型号 TOSHIBA MK6032GSX 60G
应该是sata而不是ata
转数5400
但是也不应该慢到这个程度

纠结

可能被骗了哦，用的ata的应怕，却说是sata的

晕死，这有什么好骗的。现在笔记本硬盘STAT 的多的是，而且又不是散卖的，怎么骗。
我的也是sata的，速度和楼主的差不多。
ps:在ubuntu英文官方论坛也有很多人在反映了，不过现在还没有解决办法，大家等更新吧.

看我SATA的
/dev/sda:
Timing buffered disk reads: 82 MB in 3.04 seconds = 26.99 MB/sec
更慢，看不出那里有问题。

不要意思，显摆一下

andrew@andrew-desktop:~$ sudo hdparm -t /dev/sda

/dev/sda:
Timing buffered disk reads: 212 MB in 3.03 seconds = 70.07 MB/sec

对硬盘啥都没配置，ubuntu 7.04, sata 320G 西数 7200转

偶的，奇怪啊。为什么这么快呢？
hdparm -Tt /dev/sda

/dev/sda:

Timing buffered disk reads: 114 MB in 3.01 seconds = 37.86 MB/se

升级了内核

还是没有改变

硬盘拷东西速度狂慢

[Varrily]

搞笑阿～～

关闭DMA

/dev/hdd:
setting using_dma to 0 (off)
using_dma = 0 (off)
root@Varrily-Ubuntu:~# hdparm -t /dev/hdd

/dev/hdd:
Timing buffered disk reads: 18 MB in 3.11 seconds = 5.78 MB/sec


打开DMA

/dev/hdd:
setting using_dma to 1 (on)
using_dma = 1 (on)
root@Varrily-Ubuntu:~# hdparm -t /dev/hdd

/dev/hdd:
Timing buffered disk reads: 164 MB in 3.02 seconds = 54.38 MB/sec

[skyx]

看我SATA的
/dev/sda:
Timing buffered disk reads: 82 MB in 3.04 seconds = 26.99 MB/sec
更慢，看不出那里有问题。

本本硬盘好多都是4200转/分的，只有这个速度也不奇怪。和接口关系不大的。以为ide就比sata慢并不正确。

pc高速发展的五到七年以来，硬盘提速是最慢的。

我的也是ata？？？

[hao123liu]

我的更慢

同样的命令，22楼的算最快的了。

[286485111]

最好把各参数报下.....
转速
单碟容量
平均寻道时间
潜伏时间

好让别人看看啊

别以为sata就比ata快很多....快的只是外部传输速率
内部传输数率搞不上来sata. ata不就一个样 .....
