[購買問題] 三百幾蚊 1TB,2.5 好定 3.5 好?

如題,差幾十......

係裝枱機,放 data,OS 行緊 SSD.

諗緊用2.5 又慳電 D,通風散熱又好 D,而且因為預俾 NB 或 portable 用,應該會襟 D?但速度會唔會因為碟圏細而慢好多?相反 access time 又會唔會因為碟細而 快返?

可以考慮買2.5" 7200轉的,夠快又可以做外置和俾Laptop用。速度都唔錯。

Then it has to be 3.5" but why just 1TB?
For your cause, the minimum capacity should be 2TB

Different HDD specs are designed for different use
Therefore your decision should not be simply based on price perspective

其實係大人部機,佢無咁多 data 啦,1TB 乜都夠。
佢而家隻640都未爆,不過出 C5,想趁早搬 data 啫。
唔係淨係睇價錢,仲想睇埋發熱、散熱、避震等.....2.5 都應該好過 3.5,但就係怕佢個速度爭好遠....

AFAIK 2.5" HDD's motor is less durable in general (except for 7x24 enterprise models)

Besides, if your HDD is subject to frequent data access then seriously 2.5" is not a good idea

睇埋發熱、散熱、避震等... it's all 挑骨頭

用過2.5" 5400 RPM,確實慢過3.5" 7200 RPM唔少。
一向未聽聞過2.5"會襟用D,不過會慳電係真既。

噢....因為我仲有幾隻 2.5",由60g 到 120g 到 500g 不等,好多年都好健康,而家成日「裸跑」插個 eSATA 或者 USB 就用,以為 2.5" 會襟用 D 添....始終係比portable device 用嘛....原來唔係的。

所有重要資料都要最少備兩份在不同裝置,買一隻硬碟幾百,救一隻硬碟就幾千

買2.5

2.5 seems more reliable.
