Choosing nas storage & drives means solving two problems at once: which enclosure format suits your space and how much preparation the drive setup will require. The NETGEAR ReadyNAS RND-6A RNDU6000-100NAS and Netgear ReadyNAS 2100 RNRX4410-100NAS take different approaches, with the RND-6A emphasizing a lower price and the 2100 using a different enclosure layout. Both are used, so the decision should focus on concrete format, connection, and accessory details rather than broad NAS labels.
Quick verdict
The RND-6A is the lower-priced choice, while the 2100 is the targeted choice for a particular physical setup. Start with layout, then weigh connection types, computer compatibility, and accessory needs. Both require separate drive planning, and the 2100 also lacks a power adapter. Choose the unit whose concrete details match your setup rather than treating a technical number as a quality ranking.

Where each wins
NETGEAR ReadyNAS RND-6A
The RND-6A wins when RJ-45 and USB-A are the deciding connection details. Its six-bay layout is also the direct reason to choose it when bay count drives the decision. That combination gives the enclosure a clear use case for shoppers who want the named ports and a larger listed bay count, without needing the rack-oriented format of the 2100. Choose the RND-6A when those connections and the enclosure layout fit the setup.
Netgear ReadyNAS 2100
The 2100 wins when PC/Mac compatibility is central. Its physical format is another concrete reason to choose it, especially if the surrounding setup is already organized around that style. The 3.5-inch HDD specification adds a defined drive-format criterion for planning. Choose the 2100 when its compatibility and placement requirements are known priorities, rather than paying more for details that do not match the intended arrangement.
Product notes
NETGEAR ReadyNAS RND-6A RNDU6000-100NAS
The NETGEAR ReadyNAS RND-6A RNDU6000-100NAS has a concrete reason to choose it: functionality is described as tested and working. That suits a shopper looking for a used enclosure with a stated working condition. The limitation is preparation: cables and hard drives are not included. Scratches and scrapes around the body are also described, so cosmetic wear is part of the decision. Choose the RND-6A when a tested, working unit and a separate accessory plan fit your project; the missing cables and drives are the clear constraints on that choice.
Netgear ReadyNAS 2100 RNRX4410-100NAS
Netgear ReadyNAS 2100 RNRX4410-100NAS has a clear reason to choose it for a drive plan using 3.5-inch HDDs: that form factor is specifically identified. The specification gives shoppers a concrete way to match the enclosure to their intended drive size without implying anything about performance. The limitations are practical: no HDDs are included, and the power adapter is not included. The condition is used, with minor scratches or scuffs part of the described cosmetic wear. Choose the 2100 when its drive format fits the setup; otherwise, the missing accessories should weigh against it.
Final choice by use case
- For the lower-price enclosure route: Choose the NETGEAR ReadyNAS RND-6A at USD 129.99 when the six-bay layout and separate cable and hard-drive plan are acceptable.
- For the rackmount and computer-fit route: Choose the Netgear ReadyNAS 2100 at USD 149.99 when its physical format and compatibility details match the setup, while allowing for the missing HDDs and power adapter.
