NAS Storage & Drives: Choosing 2-, 4-, or 6-Bay Enclosures for Home

Compare four NAS enclosures across 2-, 4-, and 6-bay designs, used and new conditions, connectivity, drive support, and a $303.99 listed-price spread.

Last updated Aug 24, 2026

Choosing a home NAS means balancing bay count, condition, drive support, and price before you commit. A used 2-bay enclosure may cover straightforward backups, while a 4- or 6-bay chassis gives your storage plan a different starting point. The four choices here range from a NETGEAR 2-bay unit to a Synology 4-bay enclosure, with a new white 2-bay home-cloud model between them in purpose but not in price.

Quick take

  • For the lowest listed price: NETGEAR ReadyNAS 202 RN202 offers 2 bays, hot-swappable drive bays, and Gigabit Ethernet.
  • For the largest bay count: NETGEAR ReadyNAS RND-6A provides a 6-bay design with RJ-45 and USB-A connectivity.
  • For a new home-cloud setup: The white 2-Bay NAS Enclosure focuses on private file access, backups, Android compatibility, and home monitoring.
  • For four-bay drive support: Synology DS423 lists four bays for 2.5- and 3.5-inch HDD or SSD drives and PC compatibility.

Listed-price comparison

NETGEAR ReadyNAS 202 RN202 2-Bay Network Attached Storage NAS RN20200-100NES

NETGEAR ReadyNAS 202 RN202 2-Bay Network Attached Storage NAS RN20200-100NES

The NETGEAR ReadyNAS 202 RN202 is a straightforward match for a shopper who wants a 2-bay NAS with hot-swappable drive bays and Gigabit Ethernet. Its black enclosure also lists two Gigabit Ethernet ports and USB 3.0 connectivity. The limitation is its used condition, so it suits buyers comfortable choosing a previously used unit. Accessories not pictured are not included, which matters if your setup depends on extra cables or peripherals. With its 2-bay design, the RN202 is more narrowly defined than the 6-bay NETGEAR chassis, but its listed configuration keeps the choice simple for a smaller NAS plan.

The NETGEAR ReadyNAS RND-6A RNDU6000-100NAS stands out for its six-bay enclosure. That bay count makes it the direct choice when the storage plan calls for a larger chassis rather than a 2-bay or 4-bay design. RJ-45 and USB-A connectivity are listed for the unit. Its limitations are concrete: the condition is used, and hard drives, cables, and other accessories are not included unless specifically mentioned. The description also notes scratches and scrapes around the body. Buyers focused on bay count may find the RND-6A compelling, while shoppers seeking a new enclosure should look at the two new choices instead.

2-Bay Network Attached Storage NAS Enclosure Diskless White Home Cloud Backup

2-Bay Network Attached Storage NAS Enclosure Diskless White Home Cloud Backup

This white 2-bay NAS enclosure is aimed at home users or small teams who want private file access, backups, and property monitoring in one setup. Android compatibility and a tabletop form factor are listed, while the description highlights access from desktop, laptop, Mac, PC, and mobile devices. Its quiet, low-power positioning may appeal to a home office or shared household space. The main limitation is the diskless format: the enclosure is sold without installed drives. It also uses a plastic and tempered-glass build, so its appeal centers on the stated home-cloud features rather than a four- or six-bay layout.

Synology DS423 4-Bay Network Attached Storage Enclosure, NEW, SEALED, DISOUNTED

Synology DS423 is the fit for a shopper specifically looking for four bays and support for both 2.5- and 3.5-inch HDD or SSD drives. PC compatibility, Ethernet, two Gigabit Ethernet ports, and two USB-A 3 connections are listed, giving the enclosure a clear desktop-storage orientation. The title and description identify it as new, sealed, and diskless, so installed drives are not part of the listed configuration. That is the key limitation for anyone wanting a ready-to-use unit with storage already inside. Its black enclosure and DS423 model name make the selection easy to identify when four bays are the deciding requirement.

Final recommendations by use case

  • Choose NETGEAR ReadyNAS 202 RN202 for the lowest listed price at $71.00, provided a used 2-bay NAS with hot-swap bays suits the plan.
  • Choose NETGEAR ReadyNAS RND-6A when six bays are the priority. Its $129.99 listed price and RJ-45/USB-A connectivity make the use case distinct, though drives and cables are not included.
  • Choose the 2-Bay NAS Enclosure for a new white home-cloud design with Android compatibility and monitoring features. Its listed price is $346.97, and it is diskless.
  • Choose Synology DS423 for four bays and 2.5- or 3.5-inch HDD/SSD support. At $374.99, it is the highest-priced choice here and is also diskless.

The simplest decision is to start with the required bay count, then separate used units from new enclosures. That approach puts the two NETGEAR models on one side of the comparison and the new 2-bay and 4-bay choices on the other.
