首先表明，自己是日立和三星的死忠，平日當中我也都推薦其他人選購此二品牌，但是今天不同，有客觀數據說話，我就暫時靜音先吧。
介紹一下自己所用過的硬碟。
3.5寸有：IBM 40G（2002年），
Hitachi HDT721010SLA360 1TB 3碟裝16M（2009年），
Maxtor 7H500F0 企業級500G 4碟裝16M（2010年），
HCS721010CLA332 監控級1TB 2碟裝32M（2010年）。
2.5寸有：希捷 ST9120817AS 120G 2碟裝 8M（2008年），
三星 HM320II 320G 1碟裝 8M，
東芝 MK3263GSX 320G 1碟裝 8M。
1寸有：Hitachi DK14-FA 20G 不知道幾碟 大概2M（2004）。
現在電腦吵著要升級最多的就是存儲部份，1TB現在早就不是什麽新鮮玩意了。不過好多人都比較迷茫的是不知道究竟該選擇哪一款。日立，WD，希捷，三星？
其實相對於性能方面，可能大家更關注的是大容量硬碟的穩定度以及價格問題，有關於穩定度的方面限於固有條件不能逐一測試，唯有總結經驗。價格方面畢竟各地有差，很難拿出一個標準。
此次測試一共收取了5大品牌的產品，包括了Hitachi，maxtor，Samsung，seagate和WD。測試結果為PASSMARK SOFTWARE網站公佈，採用相同條件進行對比。（PS：分數不代表讀取速度等單一性能指數，大概是類似於PCmark一類的指數吧XD）
型號之後緊隨的三位數為benchmark分數，越高越好。之後的數字代表測試排名，越小越好。
