是的，現在已經進入 2TB 的時代了！

假如您正打算為自家的農場擴增領土的話，那麼引用來源這篇友站耗費多時，精選Samsung
、Seagate 及 WD 三家廠牌十顆 2TB 硬碟進行多達 250 項的測試，嘔心瀝血撰寫的評比
文絕對值得各位好好參考一番。若是各位沒什麼時間的話，那麼請看底下癮科技為各位所
彙整的超精簡評論。

好的，請各位直接翻到最後一頁，結論就是：噹噹，用錢砸出來的 WD 黑標 RE4 2TB 硬
碟跑的最快( 每 GB 約 0.16 美元，約新台幣 5 元 )；而效能最差的也和各位猜想的一
樣，就是省能型的 WD 綠標 Caviar Green 2TB 以及 Seagate Barracuda LP 2TB ( 不過
每 GB 的單價也便宜一半以上 )拿下這個殊榮。

當然，硬碟的效能並非是唯一的考量。若只是要當儲藏室的話，慢一點但便宜許多的硬碟
也是 CP 值相當高的選擇。總而言之，不過是黑貓還是綠貓，只要不會得機瘟的就是好貓
囉！

Three HDDs exceeded write speeds of 140MB/Sec on our ATTO test: the WD RE4
2TB (144.3MB/Sec), Seagate Barracuda XT 2TB (143.8MB/Sec), and the Seagate
Constellation ES 2TB (141.0MB/Sec). Both WD Caviar Black drives also showed
strong write performance--the 2TB drive had a write speed of 138.1MB/Sec and
the 1TB version saw 133.7MB/Sec.

For read speeds, a total of five drives managed speeds that exceeded
140MB/Sec: The WD RE4 2TB lead the pack at 155.8MB/Sec, followed by the WD
Caviar Black 2TB (148.9MB/Sec), Seagate Barracuda XT 2TB (147.5MB/Sec),
Seagate Constellation ES 2TB (145.1MB/Sec), and the WD Caviar Black 1TB
(142.8MB/Sec).



As far as CrystalDiskMark's sequential write speeds are concerned, the trend
we've seen with the previous tests continues--with the fastest drives being
the Seagate Barracuda XT 2TB (142.7MB/Sec), Seagate Constellation ES 2TB
(138.4MB/Sec), WD RE4 2TB (138.8MB/Sec), WD Caviar Black 1TB (131.3MB/Sec),
and WD Caviar Black 2TB (128MB/Sec). As to the general-purpose drives, the
Seagate Barracuda LP 2TB is once again the leader at 116.8MB/Sec.

The same five performance and enterprise drives are also once again the
leaders on CrystalDiskMark's sequential read test, but they are also joined
here by the WD RE4-GP (157.3MB/Sec). As a matter of fact, the top four drives
here are all WD drives, with three in particular having standout performance:
the WD Caviar Black 1 TB (193.6MB/Sec), WD Caviar Black 2TB (179.8MB/Sec),
and the WD RE4 (177.3MB/Sec). No surprises here either with the
best-performing general-purpose drive: the Seagate Barracuda LP 2TB had a
read speed of 119.9MB/Sec.
