  • External power supply (most competitors do too, though)

Bottom Line:

The Netgear ReadyNAS Duo is a nice entry level product that gives you most all of the features and advantages of a network storage device in the ReadyNAS stable yet at the most affordable price. The newer multimedia functions like Orb, though, require Intel x86 processor which the Duo does NOT have.

Recommended configuration is RAID1 for data redundancy to help protect valuable business data, expensive music collection or irreplaceable family photos between backups. Keep in mind if you store video that 1TB can get gobbled up pretty quickly.

Review Detail:

The Netgear ReadyNAS Duo is the least expensive way to get most all of the benefits of having what I feel is the best network storage solution on your network. The ReadyNAS product line that will make setup and maintaining your NAS an enjoyable experience. It is not Intel x86 powered, though, so the latest features you see Netgear advertising do not apply to the Duo.

The Duo is limited to two SATA hard drives internally. It supports SATA I & SATA II hard drives, but does not boast native support for SATA II. This means you can use SATA II but do not expect the increased performance they have the potential for.

You can attach external USB hard drives and create shares on those drives as well. Keep in mind that performance will not be as high as the internal drives, nor will there be benefit of RAID technology on those external drives.

One of the benefits of buying any ReadyNAS product is the auto-expandable X-RAID technology. The Duo has the original X-RAID while newer models have X-RAID2. While you can configure the 2 drives as either a larger 2TB data store (RAID0), doing so means that if a hard drive fails you lose data. This is not acceptable to me, but you can decide for yourself.

RAID1, on the other hand, allows 1 hard drive to fail without losing data. The unit can easily be configured to send you an email when this happens allowing you to immediately backup!, then replace the failed drive and restore data redundancy. The downside of this is that the Duo then offers you only 1 terabyte of storage instead of 2. But what good is a huge data store if you cannot depend on it?


The ReadyNAS Duo makes an excellent home network storage device for storing data on redundant drives, sharing data, photos both within the home and even with secure remote access via the internet. Display photos, movies or other multimedia on your PlayStation or XBox; attach to the NAS for access to music libraries played with iTunes, Squeezebox, etc. Use the built in BitTorrent for downloads.

If you have a small business where you need to either store data on a more reliable platform than just your PC or need to share files with coworkers, the ReadyNAS Duo is a great entry level network server to start with. The ReadyNAS can function as your file server, print server, DHCP (network addressing) server and provide software and storage for individual PC backup.

Backup Options:

The Netgear ReadyNAS Duo really shines, as all model in the ReadyNAS family do, when it comes to data backup. Remember, RAID1 is NOT data backup! It is data reliability and availability. RAID1 (otherwise known as mirroring) means that hopefully you never have to restore a backup due to media (drive) failure. It does not protect you against data corruption (virus, power loss) or accidental deletion by the user.

Let’s face it, network attached storage is all about your data. So to make it available and reliable, we use redundant disk technology (X-RAID in the duo). To make sure we do not lose it to fire, theft, natural disaster or even our own error, we back it up.

Backup with any ReadyNAS network attached storage device can be done using any combination of the following methods:

  • Local backup to an attached USB hard drive
  • Backup to another ReadyNAS unit, local or in a remote location
  • Online backup (in the cloud backup) using the built in support for ReadyNAS vault online backup service based on ElephantDrive technology
