Two things:
a. You might want to avoid anything oric0 becuz they are unreliable and could at worst kill your HDD prematurely

An enclosure such as Transcend 25S3 is MUCH MORE reliable

b. HDD wise there's only one choice for you:
- WD10JPLX
Never tried Travelstar before but non-enterprise version has lower grade spin motor which is more prone to failure AFAIK

Also you want to avoid AV25 as this is not designed for general-purpose portable carry...
Flor instance, there's no head parking mechanism so any shock would damage the drive (if not kill it)
Also it's SATA2 NOT SATA3

不過，而家買的話，只會買套裝2.5" hdd連usb盒.

無論你所指嘅碟係硬碟、SSD還是磁帶，喺呢個世界上只有兩種儲存媒體，就係將會壞同已經壞咗，並無分話易唔易壞。

儲存媒體本身只係一個唔值錢嘅數據容器，值錢嘅野係入面裝住嘅數據。你話怕一壞咩都救唔返，係因為你無做好備份，而買所謂無咁易壞嘅硬碟，跟本唔會令啲數據安全咗，點解要拎啲數據去賭隻碟唔會壞，而唔係預咗隻碟一定會隨時壞。

由你放檔案入去隻硬碟嗰一刻，你就應該預佢下一秒就會壞，所以我買硬碟係一對咁買，重要檔案喺一定會有兩個Copy，而Backup嘅硬碟仲會用SnapRAID去做保護。
