White label = 3rd party builder/logo isn't the HD make
In effect, HDs are brought in bulk and then build by some vendor which sells them under "their logo", label like Simple Technologies, BubbaPC or Buffalo Tech., etc.. While they may use the same actual HD inside these are NOT the same whole units as Seagate or WD builds that they sell under their own logo. You have to look for warranty or support by the logo sold under.
Next, if you read here on the forums all the issues ext. HDs have, they aren't the best for prolonged storage. IMHO, all ext. HDs(any brand) are bound to cause some issue whether it be user or actual h/w failure. So, don't count on these as your primary back-up or long term storage for pics, data, or audio, sooner or later something happens. Also, it has been IMHO the primary cause of failure is "heat build-up". Most ext. HDs use "passive heat exchange" and it just sits in its own heat build-up and stews. That's not too bad for 1-platter media HD but is for multiple platter media and/or very large HDs. So, if you want an ext. HD to last, plug-in when needed and UNPLUG PROPERLY(dismount). Don't have it always plugged in and use as needed, its prone to fail. Of course, this is my opinion and generally I've found other reasons for failure to include dropage, pets, sunlight, power glitches and kids. Last, sometimes the users does a boo-boo and acted upon the wrong HD(stroage area) and deleted or swapped whole data elsewhere then back by user action or s/w feature(over-worked).
