Choosing nas storage & drives often comes down to a practical trade-off: do you want an enclosure built around more drive bays, or a named NAS server with a defined capacity? The 5-Bay Black Network Attached Storage NAS Enclosure w/ Drive Trays and LaCie 4TB 2big NAS Server; USB 3.0 take different approaches. Here is the useful split: the enclosure prioritizes bay count and drive trays, while LaCie gives you a specified 4TB configuration and Mac/PC compatibility.
Quick verdict
The 5-Bay Black Network Attached Storage NAS Enclosure w/ Drive Trays is the clearer fit for shoppers who want an enclosure format and five-bay layout at the lower listed price. The LaCie 4TB 2big NAS Server; USB 3.0 suits someone who wants a specified capacity and a server designed for both Mac and PC use. The listed price spread is $130, with the enclosure at $170 and LaCie at $300. One important distinction: the enclosure is used, its power indicator turns on, and no additional testing has been done. That makes the choice depend on whether your priority is the hardware format or a more specifically described storage configuration.

Where each product wins
The 5-Bay NAS Enclosure wins for an enclosure-first setup
Its clearest advantage is the combination of drive trays and a five-bay layout. That makes it the more direct match for a home or small-office shopper whose priority is an enclosure built around multiple drive positions. The lower listed price also keeps the purchase focused on the chassis format rather than a specified preconfigured capacity. Choose it when the number of bays and included trays are central to how you want to plan your NAS storage. The compromise is the used condition and the explicit statement that no additional testing has been done, so its appeal rests on the described enclosure features rather than a reported operating result.
LaCie wins for a defined capacity and mixed-computer use
LaCie offers a more specific storage proposition: a 4TB 2big NAS Server with listed compatibility for Mac and PC computers. That is a clearer fit for someone who wants a capacity stated upfront and expects to use the server across different computer platforms. The silver finish is another concrete difference, although it does not establish a performance advantage. The two-bay layout is the main trade-off against the enclosure's five-bay design, and the listed price is higher. Choose LaCie when the defined capacity and cross-platform compatibility matter more than having a larger bay count.
Product notes
5-Bay Black Network Attached Storage NAS Enclosure w/ Drive Trays

The 5-Bay Black Network Attached Storage NAS Enclosure w/ Drive Trays makes sense for an enclosure-first build. Its practical draw is the combination of drive trays and the five-bay layout, giving shoppers a clearly described chassis for a home or small-office storage setup. The black finish is a straightforward design detail, and the lower listed price supports choosing it when format and bay count matter most. The limitation is equally concrete: it is marked used, the power indicator turns on, and no additional testing has been done. That means the strongest reason to choose it is the enclosure specification, not a claimed performance result. It is less suitable for shoppers who specifically want a stated storage capacity and Mac/PC compatibility.
LaCie 4TB 2big NAS Server; USB 3.0

LaCie 4TB 2big NAS Server; USB 3.0 is the clearer choice for shoppers who want a capacity-specific NAS server. Its listed Mac and PC compatibility also suits a mixed-computer household or small office. The silver finish and 2big model name provide concrete identifying details without requiring assumptions about speed or performance. Its limitation is the two-bay layout, which gives it fewer bays than the five-bay enclosure, while the listed condition is used. Pick LaCie when a defined storage configuration and cross-platform use are more important than an enclosure with drive trays. The recommendation is based on its stated capacity, server format, and compatibility-not on an unreported test outcome.
Final choice by use case
- Choose the 5-Bay Black Network Attached Storage NAS Enclosure w/ Drive Trays if you want a five-bay enclosure with drive trays and your priority is an enclosure-first NAS setup. Keep its used condition and untested status in the decision.
- Choose LaCie 4TB 2big NAS Server; USB 3.0 if you want a specified 4TB NAS server with listed Mac/PC compatibility and are comfortable with a two-bay design.
- For the lower upfront price, the enclosure is the direct pick. For a defined capacity, LaCie is the more specific match.
