NAS 必備 WD Red 系列硬蹀限時特價

wd red plus

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。
