Try unRAID.

We’ll convince you it’s worth it in 30 days or less

  1. A quality USB flash device between 512MB and 32GB in size.
  2. A 64-bit capable processor (Intel or AMD).
  3. At least 1 GB of RAM for basic storage functionality.
  4. More requirements apply if you are looking to install apps or VMs.

Additional Requirements

  1. Insert a recommended flash device into your Mac or PC.
  2. Format the device using the FAT32 file system.
  3. Set the ‘volume label’ to UNRAID (case-sensitive; all caps).
  4. Go to the download page.
  5. Download the latest release to a temporary location on your computer (e.g. a “downloads” folder).
  6. Extract the contents of the newly downloaded ZIP file onto your USB flash device.
  7. Browse to the USB flash device (using Windows File Explorer or Mac Finder) to see the newly extracted contents from your Mac or PC.
  8. Run the make bootable script.
    • From Windows XP, just double-click the make_bootable file.
    • From Windows 7 or later, right-click the file and select ‘Run as Administrator’.
    • From Mac devices, double-click the file ‘make_bootable_mac’ and enter your admin password when prompted.  NOTE:  during the process of running this script, the flash device may seem to disappear and reappear on your workstation a few times – this is expected behavior.

How many storage devices can I use with the trial?

As of unRAID 6.2-rc1, trial users can have any number of attached devices.

How long does the trial last?

Trial registration keys last for 30 days. If you need a little more time to evaluate after it expires, you can navigate to the Tools > Registration page and click Request Extension. You can request up to two extensions per trial registration.

I just used up both of my trial extensions and still need more time, can I get another?

Sorry, but no. Once you extend your trial twice, no further extensions will be granted.

My USB flash failed during my Trial, can I get a key replacement for my trial to move it to a new USB flash device?

No, but you can register for a new Trial on a new flash device.

What happens when my trial expires?

After your trial expires, you will no longer be able to start your array.

Are there any feature restrictions in the trial?

No.  All unRAID registration keys allow full access to the software’s capabilities.


How can I move my unRAID Trial config to a new flash device before purchasing a key?

1 – Prepare the new flash device for unRAID (format with FAT32, label with UNRAID in all caps)
2 – Copy all the files from the old flash device to the new flash device
3 – Run the make_bootable script as per the normal setup process
4 – Boot your server using the new flash device
5 – Purchase a registration key from the Tools > Registration page in the webGui

My trial expired but I need to get data off my drives, what can I do?

Each disk is formatted with its own filesystem and can be read from independently using any OS with support for the filesystem used (by default, array devices are formatted with XFS and cache devices with BTRFS). Most Linux-based operating systems come with built-in support for reading any filesystem used by unRAID.

I tried to register for a trial, but I received an ERROR (4) message.  What do I do?

This message means your system is unable to connect to our key server to register your trial.  Please ensure that your server has a connection to the Internet in order to register for a trial.  If you are unable to solve this problem, please e-mail us.
