Choosing between two used enclosures for NAS storage & drives is a practical trade-off: do you want a straightforward drive enclosure, or a configuration with more included setup hardware? The Netgear ReadyNAS 2100 and Qnap TS-431P2 sit close together, yet their parts and specifications point to different buyers. For a home NAS, the right choice is the one that fits the equipment and accessories you plan to build around it.
Quick verdict
Netgear is practical when PC/Mac compatibility and HDD support are your starting requirements. Qnap is better aligned with shoppers who want four included caddies. Netgear also carries the lower listed amount; the absolute spread is $19.96. That makes this a setup-fit decision rather than a reason to assume one unit will be faster.

Where each product wins
Netgear ReadyNAS 2100
Netgear wins on its connection and form-factor details: USB 3.0 and a 3.5 in form factor are both stated. Those specifics help a shopper map the enclosure to an existing computer-and-drive plan. They describe supported connections and format, not a speed or performance advantage.
Qnap TS-431P2
Qnap wins on the included bay accessories and the way it is described: four caddies are included, and it is presented as a 4-bay personal cloud NAS. That is a concrete distinction for anyone who wants the bay hardware accounted for before selecting storage. The difference concerns the listed configuration, not a claim of greater performance or capacity.
Product notes
Netgear ReadyNAS 2100 RNRX4410-100NAS
The Netgear ReadyNAS 2100 RNRX4410-100NAS is a clear fit for an HDD plan. Its details identify HDD support and a 3.5 in form factor; the silver color gives the listed unit a specific finish. The limitation is explicit: no HDDs and no power adapter are included, so storage and power must be sourced separately. The unit is marked used, making it an enclosure purchase rather than a complete storage bundle. Choose it when that drive format and finish suit your setup; the missing components are the practical trade-off.
Qnap TS-431P2
Qnap TS-431P2 suits a shopper who is comfortable buying the NAS unit separately and planning the rest of the storage setup around it. Its package is described as unit only, which can fit a build assembled in stages. The limitation is equally concrete: no drives and no power adapter are included, so storage and power must be added separately. The condition is used. Choose Qnap when that separate-unit format matches your plan; its role as a personal-cloud NAS gives the enclosure a clear use case without promising a particular performance level.
Final choice by use case
- For PC/Mac use: Choose Netgear ReadyNAS 2100 because compatibility with both platforms is explicitly stated.
- For a personal-cloud NAS format: Choose Qnap TS-431P2 because it is described as a 4-bay personal cloud NAS.
- For connection planning: Netgear is the clearer fit if USB 3.0 is important to your setup.
The bottom line is simple: Netgear is the clearer drive-and-connection match, while Qnap is the clearer accessory-focused match. Neither should be selected on an assumed speed advantage. Choose based on the setup you intend to assemble around the enclosure.
