Choosing between a simple network attached storage drive and a rack-style server can change what you buy: do you want a defined-capacity external drive for sharing files and photos, or a multi-bay NAS server whose title says the hard drives and caddies are not included? This head-to-head makes that fork clear. The WD My Book Live and QNAP TS-809U serve different briefs, so the right choice depends less on a generic winner than on whether your priority is an external storage device or server hardware.
Quick verdict
Choose WD My Book Live if the external-drive format and file-and-photo-sharing language match your plan. Choose QNAP TS-809U if you specifically need the 8-Bay 2U Rackmount NAS Storage Server format. The listed-price spread is USD 193.76, making price a meaningful divider, but it does not erase the difference between a personal storage device and rackmount NAS hardware.

Product notes
WD My Book Live

The WD My Book Live is the straightforward pick when the goal is an external-drive format that names file and photo sharing right in the title. Its 3 TB storage capacity gives the purchase a clear, specific role within NAS storage and drives, while the Personal Cloud Storage wording points toward an at-home file-access use case. The limitation is the Used condition, which is part of the product's listed state, so it may not suit someone who specifically requires a new-condition purchase. The title also frames it around personal cloud storage rather than a multi-bay rackmount server. If your brief centers on a defined-capacity device for personal files and photos, the WD wording is closely aligned.
QNAP TS-809U

The QNAP TS-809U is aimed at a different brief: an 8-Bay 2U Rackmount NAS Storage Server with Remote Access listed as a feature. Choose it when that server-oriented form and remote-access role matter more than an external-drive format. Its clearest limitation is in the title itself: No HDDs No Caddies. The listed unit therefore does not include those components, making the purchase a distinct hardware-setup decision rather than a simple storage-drive choice. It is also Used, and the 1 GB cache is a specification rather than a reason to assume faster or better results. For a rackmount NAS plan, the QNAP title is direct about the intended hardware format.
Final choice by use case
For a personal-cloud file-sharing brief, choose WD My Book Live. Its listed price is USD 76.99, and its external-drive wording keeps the purchase focused. For a rackmount server brief, choose QNAP TS-809U. Its listed price is USD 270.75, and the 2U server format is the defining reason to select it. Pick based on the hardware brief first: the lower price cannot substitute for rackmount server hardware, while the QNAP's server format does not change its No HDDs No Caddies limitation.
