ICH7有支援SSD固態硬碟嗎?發揮出ssd的效能嗎?謝謝
只要有SATA port,都可以使用SSD。
IDE port也可以使用SSD,只要能找到適用的轉接卡,SATA轉成IDE。
只是SSD的讀取、寫入速度會被SATA的等級限制。
例如,SATA 1(=150MB/s)、2(=300MB/s)、3(=600MB/s),
支援SATA 3速度的SSD就會被ICH 7限制在SATA 2,
如果SSD可以跑到讀取400MB/s,如果插在SATA 1 port上,
用測試軟體測出來的讀取速度就會被限制在150MB/s以下,
打個8折,大概都會跑到極限值120MB/s吧。
不過,雖然SSD讀取、寫入速度會被SATA的等級所限制,
但在使用上的感覺,頻寬SATA 1和2比較,
在一般使用上,基本上已經是接近無感(幾乎沒有感覺),
感覺幾乎一樣快(我猜最多開機差3-5秒內吧),只有測試數據上的不同。
現在的SSD都有支援"TRIM指令",這和作業系統有關,和AHCI無關。
請參考之前的討論文章,SSD支援TRIM指令和AHCI、SATA、IDE和作業系統的關係。

如要在SSD上安裝WinXP,
我建議使用INTEL這品牌的SSD,
因有Intel官方出的Intel SSD Toolbox可以使用,其功能是模擬作業系統下TRIM指令。
(Intel SSD Toolbox安裝之後,需再自己設定intel SSD Optimizer每周排程。)

ICH7-M 真的很無言
只有SATA 1 ....
最近幫W7J換上EZLINK 60G
真的跑不出SATA2速度....
不過是比傳統硬碟快啦...

Crucial SSDs and TRIM/Garbage Collection
Since not all operating systems support TRIM, Crucial SSDs have a special feature called Active Garbage Collection. Active Garbage Collection is a process that helps an SSD maintain optimal performance by freeing up memory sectors that are no longer in use. Garbage collection is part of the SSD itself and thus not dependent on your computer’s operating system. Since garbage collection is part of the SSD’s firmware, it works regardless of which operating and filing systems your computer is using.
Note: Garbage collection only works when your Crucial SSD is idle, so make sure to configure your system so it doesn’t go to sleep when it’s idling. Garbage Collection takes time to do its job, but as long as it gets time to idle every now and then, your Crucial SSD will maintain its high level of performance over time.
