[问题]求助！SATA硬盘传输速度超慢仅仅28M／S

joyolee · #1

请各位大大给看下，为啥速度这么慢

内核 2.6.20-15-386

用sudo hdparm -t /dev/sda 查看速度显示如下

代码：全选

joyolee@joyolee-PKUUQ:~$ sudo hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads:   86 MB in  3.02 seconds =  28.48 MB/sec

用sudo hdparm -I /dev/sda 查看硬盘信息如下

代码：全选

joyolee@joyolee-PKUUQ:~$ sudo hdparm -I /dev/sda

我的raid0都只有70M不到，实在是SATA硬盘需要提高速度了

还是内核问题么？

copy一个文件慢到不能忍了

也许是把,,,我想自己编译内核看看,但目前还是在收集资料...不敢贸然动手啊~~~~

我们在讨论的是SATA，如果是IDE的还需要讨论么？

从LZ的hdparm信息来看，LZ的硬盘是ATA的，不是SATA的。可能是LZ看到sda设备名以为是SATA的，此外LZ的dma好像是开着的udma5,之所以速度低，可能是转数低吧，LZ的硬盘是不是笔记本硬盘呢

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

可能被骗了哦，用的ata的应怕，却说是sata的
