咁本身個2.5"有無用先??

即係好平就唔介意買?

The 2.5" hdd is new and no immediate need to use it.

係呀！每樣野都有個價嘛。

so the whole picture: u have a brand new 2.5" WD external hdd, you need a hdd as the primary backup storage to backup photos and important data.  Will u just use the 2.5" or u will buy a 3.5" for this purpose and use the 2.5" for something less important?

如果有錢, 我會買2個HDD set RAID 1; 但就你個問題.... 我會用2.5" 算, 慳返啲錢

what is the different of 2.5" & 3.5"????

ok.. that means strictly speaking a 3.5" hdd is a touch better because of the cooling, but other than that, you would still trust that a 2.5" is reliable enough to store your important data?

咁 minnie 用咗個咩荀價入咗你??

要講到咁仔細, 3.5" 仲可以再唔同level, 例如專比 server 用嗰啲, 一定 reliable 好多喎; 2.5" SSD 一定快..... etc!! 我只係用家庭用戶嘅角度去講, 2.5" 一般正常用法都安全夠用
