Bottom Line:

The Netgear ReadyNAS 2100 is an exceptional network storage device that is perfectly adequate to base an entire small business network around, or provide a very cost effective SAN for medium size businesses or an enterprise.

For the most part, the ReadyNAS 2100 is the equivalent of the ReadyNAS NVX only in a rack mount form factor. The hard drives you get in the 2100 are enterprise class drives that are more reliable than ordinary consumer models.

With RAID5 you have the comfort of knowing that no data is lost if you lose just one drive and get it replaced promptly, but who needs that hassle? A more reliable drive gives you better piece of mind.

This NAS is a solid, versatile and reliable performer. With more businesses moving to a virtual server environment, the iSCSI capability makes the 2100 an ideal network storage device for virtual machines.

Review Detail:

The Netgear ReadyNAS 2100 utilizes some of the most advanced network storage technologies available. Intel embedded CPU, a healthy 1GB of RAM, 2 gigabit network connections and iSCSI capability tell you that this NAS is ready for business up to the enterprise level.

It supports SATA I & SATA II hard drives, with native support for SATA II. This network storage device performs well.

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.

In a business environment, I would only use those external drives for on-site backup or for offloading seldom used data that is backed up somewhere else but you want to have ready access to.

Obviously this can be less than ideal in a rack environment, but at least you have the option.

One of the benefits of buying any ReadyNAS product is the auto-expandable X-RAID technology. The 2100 has the newer X-RAID2. While you can configure the drives as a larger, non-redundant 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.

I highly recommend letting the X-RAID2 give you the optimum storage size while maintaining disk redundancy. This is actually the easiest option for you as well.

Probably the most exciting feature of the ReadyNAS 2100 is the ability to simultaneously operate with standard volumes and iSCSI support.

Virtual machine technology is super hot, and having a SAN with these features and this price point is very attractive.


The ReadyNAS 2100 is designed for the business environment but can acually offer the same media handling features as the desktop family of ReadyNAS network storage devices.

If you have a small business with a planned or existing equipment rack and you need to either store data on a more reliable platform than just your PC or need to share files with coworkers, the ReadyNAS 2100 is an extremely competent network server to build your network around.

The ReadyNAS can function as your file server, print server, DHCP (network addressing) server and provide software and storage for individual PC backup.

The ReadyNAS 2100, like it’s desktop sibbling NVX, can even replace a Microsoft Server or Small Business Server if you decide you want to simplify and save on maintenance, licensing and consultant costs.

Backup Options:

The Netgear ReadyNAS 2100 really shines, as all model in the ReadyNAS family do, when it comes to data backup. Remember, RAID1/RAID5/X-RAID 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-RAID2 in the 2100). 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 ElephantDrivetechnology

Medium sized business and enterprises find the ability to synchronize with another ReadyNAS at a remote site extremely valuable for disaster recovery planning.
