New Features

TiVo® Integration

NETGEAR ReadyNAS is the very first NAS to be certified TiVo compatible and that’s because NETGEAR owns ReadyDLNA and has integrated DLNA support with TiVo.  TiVo users have had the option of playing back video streams (along with photos and music) from the ReadyNAS in the past, but with Ultra, you can now save your favorite programs to your ReadyNAS for future playback by just using your TiVo remote control.

Remote DLNA media streaming with Skifta and ReadyDLNA

DLNA is the buzzword that you’ve been hearing about.  Playstation 3, Xbox 360, and popular network media playback devices support DLNA, and even your new TV and hi-fi receiver may support it.  DLNA is a standard that benefits media streaming, and the ReadyNAS was an early adopter of DLNA, allowing the it to be at the center of your home media streaming solution.  Our partnership with Skifta now allows DLNA media streaming to go outside your home.  With Skifta, you can now shift your media to your family or friend’s house and enjoy it on a remote DLNA renderer or playback device.


We had initially thought iSCSI support was only important in a business environment.  Well, we were proven wrong, and we now include iSCSI support on the Ultra.  Certain applications just don’t work across a network file sharing protocol, and they require a block-level interface, like a USB device.  With iSCSI support on the ReadyNAS, you can allocate a certain capacity from your data volume to appear as a block device, and with an iSCSI initiator on your client, you can mount that network block device and make it show up similar to a USB drive.  This allows applications like iMovie and Outlook to work seamlessly with data residing on the ReadyNAS.


Windows, Mac, Linux, Solaris

Sharing is at the heart of all ReadyNAS, and ubiquitously sharing data to all popular operating systems is what the ReadyNAS does best.  The ReadyNAS speaks various file sharing protocols, including CIFS (SMB), AFP, NFS, HTTP, HTTPS, FTP, FTPS, and Rsync, so whether you’re running any one or more of the various Windows releases, OS X, Linux, or Solaris, the ReadyNAS offers the best possible sharing experience in a heterogeneous environment.

User and Group Quotas

The ReadyNAS supports disk quotas on a per-user or per-group basis. Even with terabytes of storage, certain users or groups of users may abuse the usage norm. The quota system allows you to specify how much space each user or group is allowed to use on the ReadyNAS, and the guilty party and the ReadyNAS admin will be properly notified of any violation.

ReadyNAS Photos

Have you ever wanted to share your photos straight from your home instead of having to upload your files to a remote location?  Not only can it take forever to upload your photos and often deal with timeouts, folks who you are sharing to often need to create an account just to view your photos.  And when your family and friends want to print pictures, they’ll have to do so with a low-res file that’s optimized for display.  Don’t forget your free account comes with a space limitation, and a small one at that.  And of course, if the photo site goes under or merges with another, you’re left without your albums.

With ReadyNAS Photos, simply share your photos straight from the ReadyNAS.  No complicated router setup to do.  Simply download the free ReadyNAS add-on and PC or Mac software, and install.  Then upload your photos straight to your ReadyNAS and start sharing.


RAID disk failure protection

With everything now being stored digitally, a simple disk failure can be catastrophic, especially with the large capacity disks that are certainly the norm these days. And it really is not a matter of if but when you will have a massive data loss. Your financial records, your business data, and your whole family history captured on photos and videos can be lost at an instant.  And by chance if data recovery is possible, the cost will be quite substantial.

To protect against data loss from disk failures, the ReadyNAS uses RAID, which stands for “Redundant Array of Independent Disks”.  RAID is simply a way of pooling disks into one big virtual disk. If one of the disks in that pool fails, the data from the failed disk can be resurrected by the parity information kept on the surviving disks in the pool.  Once the failed disk is replaced, data that was lost with the failed disk can be regenerated onto the replacement disk.

The cost of safeguarding your data form one disk failure comes at a price of one disk capacity, regardless of whether your RAID volume consists of two drives or six drives. For example, a ReadyNAS with four 1 TB drives will have a protected capacity of 3 TB.   Additionally, because larger capacity disks, the propensity for a two-disk failure in a RAID set can grow as you have more disks in a pool.  On ReadyNAS with 6 disks or greater, you have the option of setting the RAID volume for dual redundancy, allowing for up to 2 disks to fail simultaneously without losing any data.

With the price of disks being relatively cheap and data loss and recovery being so expensive, it’s really a no-brainer to use RAID whenever you have irreplaceable data.

Hotplug Disk Replacement

Disk failure is inevitable, so when that time comes, you certainly don’t want to have to fumble your way through trying to disassemble your device. With the Ultra, simply press on the latch to release the disk tray, remove 4 screws that attaches the disk to the tray, replace with a new disk, and insert the disk back into the chassis, all while the unit is powered on. There’s no need to power off the chassis, and there’s no need to worry about downtime. Once the new disk is in place, the disk is resync’d in the background to provide full protection from another disk failure.

Active UPS Monitoring

Ever wonder what happens when the power goes out for a little too long and the UPS battery is drained? The ReadyNAS constantly monitors the UPS battery level and sends alerts whenever there’s a power interruption. And when the battery runs low, the ReadyNAS shuts down gracefully, avoiding any file corruption caused by unwritten cached data. Just use a UPS from the ReadyNAS compatibility list, connect the USB monitoring cable to the ReadyNAS, and everything else is taken care of automatically.

And if you have multiple ReadyNAS systems, you can connect them all to the same UPS, and the alerts and graceful shutdown are supported simply by connecting the USB monitoring cable to one ReadyNAS and setting the other units to monitor this ReadyNAS over the network.


Your data is important and you need to be aware of any anomaly on the ReadyNAS. Rest assure that the email alert system will let you know what’s going on. You will be notified when a disk fails, when a disk overheats, when a disk encounters warning signs of failure, when a fan fails, when a user or group reaches a disk quota limit, and when your volume is near capacity. It’ll even alert you in case the attached UPS is on battery. You can rest assured that ReadyNAS systems are well-prepared for non-ideal conditions just as it’s able to function optimally in ideal conditions.


Integrated Backup

If you’re looking to centralize your backups, the ReadyNAS has a web-based Backup Manager built right into Frontview. From there, you have the option of scheduling backups to or from the ReadyNAS shares. You can opt to backup from a remote site over CIFS, NFS, FTP, HTTP, or RSYNC protocols, or similarly backup the ReadyNAS share to a remote site. You can even perform backups between the ReadyNAS and an attached USB disk drive or to another ReadyNAS.

Programmable Backup Button

We’ve made the Backup Button on the front of the Ultra quite powerful.  By default, pressing the button will backup the content of the backup share on the ReadyNAS to a connected USB storage device.  However, you can override this behavior with any one or more of the backup jobs that’s defined with the Backup Manager (see above).  With just a press of the button, you can now have the Backup Manager start off a series of pre-defined backup jobs in sequence.

Time Machine

The best way to backup your Mac is with Time Machine. But you don’t have to be stuck using Time Capsule if you have a ReadyNAS. Just enable the Time Machine service on the ReadyNAS and start backing up all the Macs on your LAN straight to the ReadyNAS via Time Machine.  Whether you need one file or need to restore the entire Mac image (such as when you’re upgrading a hard disk on the Mac), having the Time Machine backup on the ReadyNAS can be invaluable.

Continuous Data Protect (CDP) Backup

The ReadyNAS comes with a 3-user license of Memeo Backup Premium.  This software resides on the CD that ships with the ReadyNAS. Backup Premium utilized CDP and versioning to give you instantaneous backup of your PC or Mac data, and allows you to revert back to any of the earlier version of a file.  Simply select the folder you want to backup and forget it.  Backup Premium works great with your laptop, even in disconnected mode, queuing up all the changes until your laptop is reconnected to your ReadyNAS network.  When you need to restore an earlier version of a file, simply right-click on a file and you can select the revision that you want to restore to.

Network Recycle Bin

Windows users accustomed to the Recycle Bin on their PC will love the Recycle Bin on the ReadyNAS. If you’ve ever inadvertently deleted a file, you know well the anxiety as you frantically search for a backup somewhere. With the Recycle Bin option on the ReadyNAS, you can relax, because your deleted file will be found in the Recycle Bin of your ReadyNAS share.  Simply define how large your Recycle Bin will hold and how long to hold the files there.

ReadyNAS Vault

The ReadyNAS can be the absolute center of your storage world, but what happens when a catastrophe takes the ReadyNAS with it? It’s a smart idea to think about disaster recovery, and with ReadyNAS Vault, offsite backups can be enabled in a matter of minutes. With ReadyNAS Vault, all your backups and restores are controlled in the cloud, so you’re never more than a quick Internet access from managing or accessing your backups.  You can even share your backup files or folders safely with others, and they’ll have access to just the files or folders you share whether your ReadyNAS is turn on or not.

Take a look at how quickly you can get going with ReadyNAS Vault.



X-RAID2 Automatic Volume Expansion

There’s really no need to understand RAID on a ReadyNAS. The Ultra comes pre-configured with X-RAID2, NETGEAR’s exclusive automatic expandable RAID technology. With X-RAID2, complex RAID management is a thing of the past!

For instance, let’s say you start out with one disk and you treat the ReadyNAS as secondary backup. If one day, you want to make the ReadyNAS a primary backup or primary storage, it’s prudent to make the storage redundant. To do this, you simply secure a 2nd disk with 4 screws to the disk tray and hot-add the disk while the system is still running (you can do this while the system is powered off if you prefer). Your data on the first disk will automatically mirror to the 2nd disk in the background while the ReadyNAS is available for access on your network.

Now if you’re close to reaching the capacity on your ReadyNAS, just add a 3rd disk, and your volume expands on the fly, giving twice the original capacity, and maintaining protection from a disk failure. And again, if you add a 4th disk, your ReadyNAS will triple in capacity.

That’s not all with X-RAID2. If you find that you’re close to capacity on the four disks (or six on the 6-bay ReadyNAS), just replace two of the disks one by one, allowing it to sync along the way, and just reboot the ReadyNAS to expand the data volume. You can continue to replace each of the lesser capacity disks and reboot to gain more capacity after that.

Click on the image below for a demo on how volume capacity is expanded (demo is based on a 6-bay ReadyNAS).


Other NAS may tout that they have “online” RAID expansion just like X-RAID, but take a closer look and you’ll see it’s just not quite the same. Not only are there complex RAID migration steps involved, but they don’t mention that if you encounter a power loss during the process, you can say goodbye to your entire data volume.  With X-RAID2, you can turn off the power as many times as you want during the expansion, and it’ll continue where it left off.


Because the ReadyNAS is an energy efficient device, they tend to be kept on 24/7.  Yet because the ReadyNAS is also quite powerful, the ReadyNAS can be extended to take on more duties than simple file sharing and backups.  This is possible through the ReadyNAS add-on architecture.  It’s a simple, powerful, and open architecture that’s available to anyone that wants to create an add-on application that runs right on the ReadyNAS.

ReadyNAS Photos, BitTorrent, ReadyNAS Remote, ReadyDLNA, and TiVo are just a few examples of applications made available through add-ons by NETGEAR.  Skifta, and SqueezeCenter are some add-ons available through our growing third-party partner program, and more are just around the corner.  There are also quite a number of add-ons available online from our community at  Our community developers have written add-ons to extend the ReadyNAS into a full-fledged website, a news grabber, web file manager, and more.

Just as X-RAID2 extends the life of the ReadyNAS by allowing you to continually expand its capacity, the add-ons make the ReadyNAS continually expandable through new and exciting features.

Media Streaming

ReadyDLNA with TiVo integration, PS3, XBox 360 support

DLNA we feel is a key piece to integrating the various media devices in your home, and we’ve made ReadyDLNA is a superset of DLNA.  Not only are you able to stream photos, music, and video to your PS3, XBox 360, and other DLNA players and renderers, you can use ReadyDLNA to stream media to your networked TiVo devices.

And with Ultra, we’ve stepped up the TiVo experience a step further.  Now, you have the option to save your non-DRM TiVo programs to the ReadyNAS and playback these shows on any of the TiVo devices in your home.  What this means is that you can now record multiple episodes of your favorite seasons or sports programs without worrying that you’ll run out of space on your TiVo.  For TiVo users, there’s no other NAS out there that’ll do that for you.

Logitech SqueezeBox

The ReadyNAS is the first NAS to natively support SqueezeBox and currently is only one of two NAS architectures that Logitech makes add-ons available.  The reason?  Our engineers work directly with SqueezeBox developers to ensure the best possible experience from a NAS, and it’s no wonder the ReadyNAS is the number one choice of SqueezeBox users and developers.

iTunes Server

The popularity of iPods, iPhones, and iPad devices has a lot of folks using iTunes to archive and playback their musical collections on their Macs and PCs.  But what if you wanted to centralize your music library on one device where your various desktops and laptops in your home can access it?  With the ReadyNAS, you can do this.  Just enable the iTunes service on the ReadyNAS and start moving your files to the ReadyNAS.


SONOS has some of the coolest multi-room music playback solutions and the ReadyNAS fits in nicely into every one of them.  Just store your music on the ReadyNAS and point the Sonos library to the ReadyNAS.

Remote Access

ReadyNAS Remote

For an even more seamless remote access experience, ReadyNAS users can now use ReadyNAS Remote to securely access the ReadyNAS remotely, going over CIFS/SMB and AFP without the use of a VPN. Setup is simple, and once connected, Windows users access the ReadyNAS users with the Windows File Explorer and Mac users access the ReadyNAS with the Finder, with the same share restrictions that you’ve imposed for the LAN.  No more uploading files one by one with a clunky web-based file explorer.  ReadyNAS Remote in itself is worth choosing a ReadyNAS.

Take a look at how quickly you can start using ReadyNAS Remote.


Remote Media Streaming

Our third-party add-ons, including Skifta (see New Features), opens up options for remote media streaming.  With Skifta, you can now shift your media to a remote DLNA player or renderer by forwarding your ReadyDLNA content to a remote location.

Other Remote Access Methods

With so much data on the ReadyNAS, it’s certainly desirable to access that data remotely with standard protocols. The ReadyNAS allows this via FTP and HTTP, and the more secure and SSL encrypted form via FTPS and HTTPS, with appropriate port forwarding on your router. Simply use your favorite FTP/S client to connect to the ReadyNAS FTP server, or use your browser to access the built-in Web File Manager via HTTP/S. In addition, the ReadyNAS supports WebDAV, allowing drag & drop file explorer support over LAN or WAN. A simple tutorial on how to do this can be found here. And with Wake-On-LAN support, you can wake and boot up your ReadyNAS Ultra remotely from a power-off state.

Energy Efficiency

Low-power Consumption

It’s nice to see a lot of companies start thinking about making their products green. It’s now the in thing to do and that’s a good thing. Well, the ReadyNAS product line has always been green even before regulations and consumer demand. For instance, the Ultra 4 with one disk consumes only 31W or power and with four disks consumes 48W in idle mode.  Normal disk activity only adds a few more watts.

Disk Spin-down

If you enable disk spin-down mode, you can cut down energy usage lower.  For instance, the Ultra 4 consumes only 25W when disks are spun down.  You can specify how long before the spin-down takes effect, and once the disks are spun down, it open takes a few seconds to automatically spin back up when there is access.

Power-on Schedule

Furthermore, if you utilize the automatic power-on timer, you’ll save even more. For instance, if you plan on accessing the ReadyNAS only during an 8-hour window each day, your average consumption over the course of the day can be reduced by 66% — all without compromising performance.


Wake-On-LAN (WOL)

And if you will be on the road, you can simply shut off the ReadyNAS Ultra. When you need to access it, you can use the Wake-On-LAN feature to wake it up. Now, that sure beats running a PC, a monitor, keyboard and mouse at 100W+ 24/7.


New 64-bit Intel architecture

The Ultra line runs on a fast single and dual-core Intel 64-bit processors with RAID processing that will outrun what most home PCs can drive across the network.  In fact, throughput to the Ultra across a gigabit network will often be faster than throughput to the local hard disk on the PCs.  The faster speed opens up potential for more CPU-intensive applications to be run straight on the ReadyNAS allowing for exciting potentials for add-ons from third-party and community add-on developers.  That said, the Ultra architecture ensures that the ReadyNAS is energy-efficient, with each Ultra using power comparable to a typical light bulb, and even less when various power-saving options are enabled.
