8M 不知道要不要買....

問一下, 在系統組件問沒人回答...
IDE <-->SATA 之間對傳 是不是會超超超慢?
或者, SATA沒有開NCQ 是不是會比IDE還慢?
上禮拜裝的電腦有這樣的問題...

可能設定有錯
不然不應該這樣

會不會IDE跑PIO Mode?

IDE 在新電腦 跑的是 DMA 2 多重文字模式 ...
可是拿到我原本電腦接上去就是 UDMA5
而且 SATA自己跑起來也很慢耶....
不管在BIOS設定為 IDE或是ACHI

8M的本來就賣2800左右 所已除了可刷卡含稅之外 好像沒別的好處...

再加上運費~
通常Y拍都是便宜一點點而!!
重點就是不用去光華人擠人

好像又標錯了
 

標題是"Seagate 320GB 3.5吋 SATAII硬碟"
但是型號是"ST3320820AS/P"
依照型號來看應該是IDE 8M的，請見此

詢問辜狗大神的結果
是SATA II 沒錯的唷
ST3320820AS SPEC

ST3320820AS SATA buffer 8M
ST3320620AS SATA buffer 16M

賣到現在還沒賣完
表示大家不想幫pchome出清庫存.....
