NAS 必備　WD Red 系列硬蹀限時特價

雖然 SSD 是很多人的選擇，但容量需求大的人或者 NAS 用戶，硬碟 HDD 仍是必然之選，買了 NAS 要配硬碟，以下為大家介紹選硬碟心得。

WD Red VS Red Plus VS Red Pro

以 NAS 用的 WD Red 系列，當中分為 Red、Red Plus 及 Red Pro，三者也適合用作 NAS 硬碟之用，效能當然按價格而有所不同。

當中以 Red Plus 及 Red Pro 有注明可 24/7 使用，適合用在 RAID 環境。而 Red Pro 更有 7200 RPM 的高速，但如果只是用作一般備份，7200RPM 跟 5400 RPM 分別不明顯。

總括而言， WD Red 主要為個人或家居環境下使用，而中小公司則可用 WD Red Plus，中型公司則可選 WD Red Pro。

NAS 硬碟選購心得：買大一點

用於 NAS 的話，要看你的硬碟是多少 Bays，若 2 Bays ，想令資料安全一些一定是使用 RAID1 作 Mirror 之用。那就是 2 台硬碟壞了 1 台也可救回資料。因此，買 2 台 6TB 的硬碟，雖然總容量是 12TB（2X6TB），但可用空間只會是 6TB（一半用作 Mirror）。因此，建議用戶盡量買「大一點」，始終 NAS 用的時間取少數以年計，你未來的資料需求可以很高。而且你未來很難更換硬碟擴充容量。

NAS 硬碟選購心得：留意耐用性

硬碟一般也很耐用，但有些硬碟會指明是特別為 NAS 而設，這些用於 NAS 系列的硬碟會公佈一些數據，例如每年大約能讀寫多少 TB 作參考。

WD Red Plus 優惠

高容量的話，WD Red Plus 是首選，14 TB 降價 19%，而 10TB 則降 26%。留意，部份 Red Plus 有 7200RPM，速度較快。

4TB – 24%
6TB – 39%
10TB – 26%
12TB -21%
14TB -19%
