Ups for running external desktop hdd

[amn87]

Hi everyone I am planning to buy WD Caviar Green 2TB and use it in a dock as my laptop's primary drive. So I need a ups for powering the dock. My question is do I need an online ups or line interactive one will do. I just want dat the system should not restart in case of power failure. And what abt pure sine wave vs approximate sine wave? Most APC models are of the later type only. Another thing are docks reliable for 24x7 operation? Here is the dock am considering. . Amazon.com: StarTech.com eSATA USB to SATA External Hard Drive Docking Station for 2.5 or 3.5in: Electronics

Docks for 24X7 operation?
No, nor possible. Docks are not meant for running in that way.

yesss a line interactive wud suffice your need.. but that approximate sine wave will definitely reduce life of HDD
