[外置硬碟] 2.5" 外置 7200rpm 重唔重要???

諗住買隻 1T 2.5" 俾部 macbook 放剪聲 source 用

而家主要諗呢兩隻

HGST Touro S <<----貪佢有 7200rpm
OR
Transcend 25h3/其他牌子防震. 耐摔

想問問各位2.5" 外置有 7200rpm 重唔重要??? 因為我見主流隻隻都係 5400rpm
如果同 5400rpm分別好大 咁我唯有去 HGST

Thanks all!

7200轉在讀寫速度上會快過5400轉好多,但就會熱D和耗電量會高D。

咁做放 source 同埋錄野 外置  7200rpm 係咪好啲? 定 5400rpm都冇大分別?

Looks like you want something for pro AV work
Go for 7200rpm model if you can get access to good metal enclosure
BTW 7200rpm models often come with larger cache (16MB or more) which is also important for y our cause

外置 SSD 會不會都是可考慮 ?

假如只係接機頂盒等用來錄野,由於廣播的速度是固定的,5400轉的其實也夠用,7200轉發揮唔到佢的威力。

touro S 速度一定快過其他牌子
Hdd係標準sata,方便換hdd或放電腦度用
出事率好似比其他牌子低

但沒有usb3.0真係有機會斷線

No
Becuz SSD when connected as USB3 device may not be able to run TRIM command which is important

Once the entire capacity has been used (ie. data has been filled up), performance will drop dramatically even after repeated formatting
