Two Netgear network storage units, the ReadyNAS 2100 and ReadyNAS 202, take different approaches to serving files on your network. Form factor, drive capacity, and built-in hardware all play a role in which one fits your setup. This guide breaks down the key differences so you can decide based on the storage capacity, networking features, and setup requirements that matter most.
Quick verdict
Both of these Netgear NAS units serve network storage needs, but they target different setups. The ReadyNAS 2100 is the rackmount option listed at $149.99, while the ReadyNAS 202 is listed at $71.00. They differ in drive capacity, form factor, and price.

| Number of bays | 4 | 2 |
What to keep in mind
Both of these Netgear units are used, so you'll want to confirm the exact condition of the item you receive. The 2100 listing describes the unit as refurbished and notes it may have cosmetic wear. The 202 is characterized as a 'good working pull.' Also, check the listing's accessory details: the 2100 says the power adapter is not included, and the 202 says any accessories not pictured are not included.
Where each product wins
ReadyNAS 2100 for rackmount expansion. This unit is designed for users who plan to install drives in a rack setup. It supports 3.5-inch HDDs and is compatible with both PC and Mac, giving you flexibility in client access.
ReadyNAS 202 for dual-gigabit connectivity. The 202 comes with dual gigabit Ethernet ports, which is useful for network transfers, and hot-swap bays let you replace drives without powering down the system. This makes it suitable for setups that need multiple network connections.
Product notes
Netgear ReadyNAS 2100 RNRX4410-100NAS
This NAS comes in a silver rackmount form factor with four 3.5-inch bays. It's also listed as compatible with both PC and Mac, making it a flexible hub for a networked storage setup. The catch: this listing does not include a power adapter, and the unit is described as refurbished with possible cosmetic wear, so you're getting the bare unit. The listing title also specifies 'NO HDDs,' so you're starting with an empty chassis. If you're comfortable providing your own power supply and drives, the four-bay capacity gives you clear headroom.
NETGEAR ReadyNAS 202 RN20200-100NES
The ReadyNAS 202 is a 2-bay NAS with hot-swap drive bays and a dual gigabit Ethernet interface. Its 1.4GHz dual-core ARM Cortex-A15 processor and 2GB RAM give you a capable base for a home or small-office network storage setup. The main limitation is the two-bay capacity, which caps total storage before you'd need to swap drives. The listing also states that any accessories not pictured are not included, and that the item is in 'good working pull' condition. The listing also provides default admin credentials for the web interface (user: admin, password: admin). If you're ready to go with a two-drive NAS, this is the pragmatic option.
Final choice by use case
For a straightforward network storage setup, the ReadyNAS 202 is the practical pick. For a rack-based project where you want more drive expansion, the ReadyNAS 2100 gives you the chassis and capacity to build on, but you'll need to add your own drives.
