Thinkpad T61p的UltraBay Slim放入SATA硬盤性能不如T43p啊

moonstar2k

弄的高仿的光驅(qū)位的硬盤托，里面帶PATA轉(zhuǎn)SATA接口，支持SATA，所以弄了個(gè)500G的SATA的硬盤，以下 是在光驅(qū)位和硬盤位的性能測試對比

以下是光驅(qū)位的，在t61p下，光驅(qū)位自動(dòng)被識別為hda，倒是省了必須加noprobe的選項(xiàng)，反而是在kernel加啟動(dòng)參數(shù) hda=noprobe會報(bào) kernel panic錯(cuò)誤，也就是無法被識別為/dev/sdb

[root@localhost ~]# hdparm -tT /dev/hda

/dev/hda:
Timing cached reads:   25552 MB in  1.98 seconds = 12933.78 MB/sec
Timing buffered disk reads:  196 MB in  3.01 seconds =  65.10MB/sec
[root@localhost ~]# hdparm -tT /dev/hda

/dev/hda:
Timing cached reads:   21940 MB in  1.98 seconds = 11086.19 MB/sec
Timing buffered disk reads:  196 MB in  3.01 seconds =  65.06 MB/sec
[root@localhost ~]# hdparm -tT /dev/hda

/dev/hda:
Timing cached reads:   24528 MB in  1.98 seconds = 12410.96 MB/sec
Timing buffered disk reads:  196 MB in  3.02 seconds =  64.91 MB/sec


以下是放在硬盤位上的測試

[root@localhost ~]# hdparm -tT /dev/sda

/dev/sda:
Timing cached reads:   25660 MB in  1.98 seconds = 12989.54 MB/sec
Timing buffered disk reads:  272 MB in  3.01 seconds =  90.41 MB/sec
[root@localhost ~]# hdparm -tT /dev/sda

/dev/sda:
Timing cached reads:   25064 MB in  1.98 seconds = 12684.04 MB/sec
Timing buffered disk reads:  272 MB in  3.00 seconds =  90.53 MB/sec
[root@localhost ~]# hdparm -tT /dev/sda

/dev/sda:
Timing cached reads:   25992 MB in  1.97 seconds = 13160.73 MB/sec
Timing buffered disk reads:  274 MB in  3.02 seconds =  90.84 MB/sec



后來我翻出我以前的一個(gè)關(guān)于 T43p的類似問題的帖子，發(fā)覺我以前250g的硬盤在t43p光驅(qū)位上的性能比現(xiàn)在500g的硬盤在t61p上的性能要好啊(都是7200轉(zhuǎn)的)。


hdparm -tT /dev/sdb

/dev/sdb:
Timing cached reads:   3568 MB in  2.00 seconds = 1785.87 MB/sec
Timing buffered disk reads:  228 MB in  3.01 seconds =  75.74 MB/sec



不知道有沒有什么好的辦法可以解決這個(gè)問題啊，聽說過 t61p限制了 sata的速度，也不至于連 PATA的也一起限制了吧
