如果要買Toshiba的桌上型硬碟, 最好是選擇MC03/MC04系列, 雖然讀取聲音會咕嚕咕嚕, 可是公司去年底買了10台, 24小時不停, 到現在一台都沒出問題, 等滿一年來寫心得..... 這10台是用來替換WD的硬碟, 那批WD, 10台9個月壞5台. IT被搞到快瘋掉, 想去拜拜除厄運. 老闆也怕資料真的會出問題, 允許IT一次全都換成Toshiba.

這顆是4-platter設計，實際容量不到單碟1T
MG04/MC04/MD04真正採用完整單碟1T碟片的只有5TB與6TB而已

世界上沒有這種型號...
菲律賓廠產的MD03ACA200V是4-platter、單碟600G碟片+屏蔽容量後做成
真正單碟1T的是中國廠產的DT01ACA200V與DT01ABA200V，這兩顆才是2-platter設計

MD03 改了

MD03/MC04碟片都是1TB, 那是使用short-stroked (短行程技術),並非是碟片使用舊技術.

中國廠的型號耐用度差. 建議別碰. 不是我說而已, 是原廠自己規格表上宣稱的平均使用時數就都是最低的.

我之前貼過toshiba規格, 再貼一次:

MD03碟片都是1TB?
光這點就是明顯錯誤資訊，還是說你不會看那篇?
MG03/MD03全都是舊世代單碟600G~800G的碟片
跟MG04/MC04/MD04高容量系列的單碟1T碟片磁密度不同，這是不同世代的產品
另外short-stroked講白點只不過是拿瑕疵碟片+屏蔽容量後做成低容量硬碟使用而已

況且TOSHIBA產線相關工程師都直白表示企業級MG03判等沒過的不合格品打下來改做MD03普通碟
這兩款只差在品控嚴謹度不同、PCB不同罷了，其它像是單碟磁密度都一樣
並不會像你說什麼碟片變成單碟1T
這系列同型號並不會無故改用不同單碟磁密度的碟片，那是其它系列與別牌才會這樣搞

順道一提...你貼的是The HDD Platter Capacity Database網站上的資訊
該網站上的碟片資訊也不完全正確喔，偶爾還是錯誤
因為最近幾年我一直都有在回報正確的碟片訊息給他們

MC04/MD03是1T的碟片. 無誤. 使用short-storked技術... 你再去問清楚就知道了....是使用了short-storked技術之後,每片的可用容量才變少, 其他型號不一定, 可是MC04/MD03都是使用1TB的碟片.

至於你說的可用度的問題, Toshiba的問題確實比Seagate/WD更少一點.可靠度算不錯. 哪一家硬碟敢說他的的碟片每年幾億片的每一片都是百分之百完美無缺呢?

如果要避開這種機械性與物理性衍生的問題, 那最好是改用SSD囉. 別再買傳統機械式硬碟了. 把傳統硬碟徹底淘汰掉. 別再用了. 我心中最想看到的事情就是機械式硬碟完全被SSD擊敗, 產能報銷....事實上也是往這個方向發展, 距離硬碟廠爆發財務困難的日子, 一天比一天更接近了.

別被台灣富基代理商那個模糊不清廣告給騙了
MD03不是單碟1TB碟片，單碟磁密度也跟MD04不一樣
再強調一次MD03是舊世代的產物
說真的要是MD03是單碟1T碟片的話...速度哪有可能這麼低?

話說台灣富基代理商寫的真的很隨便....廣告內容把MD03與DT01放在一起說是單碟1TB
卻沒做任何詳細說明，很多人還天真以為兩者都是
實際上只有中國廠的DT01才是，菲律賓廠的MD03不是
菲律賓廠要等到MG04/MC04/MD04才開始使用單碟1T
嘛...畢竟富基只是個"代理商"，不是TOSHIBA產線相關技術人員

你打死不信MD03用1TB碟也沒辦法. 不是代理商寫錯, short-stroked短行程容量變小, 原始碟片容量是用1TB碟

我的資料不是來自富基電通. 我也沒看富基電通的資料

另外, DT系列是大陸廠做的, 原廠可用平均時數沒有高於MC/MD系列, 是低階產品, 別買別試

說到這裡打住. 我資料沒看錯. 不想再無厘頭

花了一點時間研究MD03家族，下面這個列表還蠻清楚的
http://rml527.blogspot.tw/2010/12/hdd-platter-database-toshiba-35.html

MD03若是單碟1TB的話，7200轉的 OD sustained transfer data rate 不可能低於 200MB/s (即便用了short-stroked)
short-stroked 說穿了只是"屏蔽"掉部分讀寫頭，讓硬碟可用容量降低
