可能大家未對個速度有幾多分別而煩悶,下一次我再開post把他們的速度用程式列出就一清二楚了~~
如上面的朋 ...

The HDD I’ve tested all are 2009 model, I don’t think those are consider old.
The lower transfer rate is due to the lag in the docking station.May be I am wrong, I thought we were talking external drive, right?
In case of internal, my 3 years old ST Barracuda 7200.11 500GB 7200rpm has a read transfer rate at 89MB/s.
I know what you meant by using a faster HDD.That’s why I have a raid 0 with 4 HDD in my PC.That raid drive can achieve >250MB/s.But are we talking about the 高清player的hard disk?
Also, you can check the HDD benchmark:

I'm using two WD 1.5 T ---WD15EARS
1st buy on 9/3/2010 @ HK$815
2nd buy on 15/4/2010 @ HK$770
Don't know if they are 7200 rpm ....
Media Player by HimXXX - HD 300A
SO FAR SO GOOD WOR...

其實一開波都表示左wd不是我杯茶~只是道出原因者~~
而這裡唔係pc討論區當然要講player用的hdd,但就是想道出我的睇法~
這裡好多人都冇留意到wd是5400轉~更不了解當中分別,其實不大問題
但問題是wd既推介方式有點誤道~完全避開轉數問題...用低熱量低用電來推介,坦白講我以為是新green技術,原來只是降低效能才達到...
買左既真的冇問題,一直照用,未買的~等我過幾天將有關的分析再開post介紹,等大家知道同了解多一點後才決定
而我自己來說~同一價格下係唔會買低轉數的hdd

其實我覺得係呢個post 之下...最緊要係講出邊款harddisk 最合media player 用....anyway, 謝謝師兄無私的分享...等大家知道WD Green的實際轉速
係pc 用家的point of view, 我十分同意會選擇隻快嘅...當然穩定及耐用都重要

其實用一套戲大約40多g來睇~5400轉係卓卓有餘,實際效能上1小時能應付200g的數據量,而40g是用2小時左右來處理,對hdd來說是完全沒問題,只是同一價錢下的7200轉卻可運作到360g的分別
簡單講就是提升80%左右~這是我用hdd來傳送資料的結果而非純軟件得出的數字,可能因cpu等其他硬件影響
5400轉如果係過一套40g的片~即是12分內鐘完成
7200轉 就是6分45秒左右
你可以話只是不足6分鐘差距,但亦可以用近倍分別來形容
以上數字我日後新post時再作實際測試,以上可能有出入

耐用方面~如果像mediaplayer的hdd多數都好長命,不似os的日日轉~不過當然是小心代理
至於岩media player用的hdd我睇法有2個
1.基本上高清片過戲時都唔少時間,轉數快省時
2.熱量方面唔洗擔心太多,因為唔會用佢在一個密封式冇散熱的media player中長開24小時~所以重點是成本~如果5400轉的價位是可以平過7200轉2成左右我也唔介意用~
我隻wd壞左拎左去vst偉仕修理已9天都冇回音.........錯在自己當日冇睇清楚是否xander代理...如果唔係一拎上去一陣就ok

Sorry, I thought the Green being a slower drive was a well known fact just like the capacity, 1GB is not equal to 1024MB on HDD.Also, the place I usually shop at shows the rpm information.
Anyway, I personally dislike the way of WD’s marketing also.They label their drive with Green, Blue, Black, and Raptor, which is confusing.I would like a HDD companies release data like rpm, number of patters, cache size, and the “true” capacity not the 1GB=1000MB.
同一價格下係唔會買低轉數的hdd
Agree.But my 5400rpm WD is half the price of a 7200rpm, and that’s why I choose the 5400 HDD for my media storage.
Wait!I am wrong. {:6_162:}The WD Green is not running at 5400rpm in “fully active mode”.It has a variable rpm with a range from 5400 to 7200 rpm.
See here:
http://support.wdc.com/product/kb.asp?fid=wdfCaviarGreen_SATA32&wdc_lang=en
That means the place I shop at has given me wrong info.hummmmm......{:6_131:}
Higher RPM = Higher Vibration, is 7200rpm HDD is a must for these media player?Even a 5400rpm HDD is good enough for normal data transfer.I think a lower speed with less heat storage device is ideal for these players.
P.S. I don't own any of these player but purely from the specification, any HDD you can purchase from market now is good enough, even the slowest one.
I think the main difference in 5400rpm Vs 7200rpm can only been observed when the HD is inside the PC.
If you use the media player , you can't tell the difference.
