QNAP QTS 5.0Source: QNAP

QNAP is working hard on revamping its QTS operating system for NAS enclosures like the TS-431X3. Version 5.0 is currently in public beta for testing and is set to be quite the substantial upgrade for enclosures, introducing performance improvements, visual enhancements, as well as some other handy features.

The company makes some of the best NAS for home, so it’s good to see the company looking to enhance the experience with the OS. The big update in question is QTS 5.0, which is quite the overhaul. The beta launched in June 2021, and we’ve had a chance to play around with the update to see what’s new. Here’s everything you need to know about QTS 5.0.




The QNAP TS-451D2 is a great home NAS with an attractive price and plenty of performance. The enclosure has four drive bays, an Intel processor, upgradable RAM, and full support for QTS 5.0 once it releases.

QNAP QTS 5.0: When will it be released?

QNAP hasn’t yet stated when QTS 5.0 will be made available for the general public outside of testing. The beta period ends on July 31 for collecting feedback from testers, so we can’t see it being much longer before the release candidates are made available.

QNAP QTS 5.0: How to install

I highly recommend installing and testing the beta of QTS 5.0 on a NAS enclosure you are not currently using in a live environment. It’s still in beta and isn’t ready for the real world just yet. You won’t be able to downgrade your NAS once you’ve upgraded it to the QTS beta. Ready? Here’s how to install QTS 5.0 on your QNAP NAS:

  1. Go to the ASUSTOR website.
  2. Select the product type, bays, and then model using the drop-down menus.
  3. Select Operating System
  4. Scroll down and select one of the download links for build 20210701 public beta.
  5. Log into your QNAP NAS.
  6. Go to Control Panel > Firmware Update.
  7. Click Browse.
  8. Select the downloaded QTS beta file.

The NAS will then run through the installation process and will reboot. Sit back, relax, and read through the list of new features in the meantime. The beta test period ends on July 31, so be sure to submit all your feedback by that date.




If you’re looking for the best value NAS from QNAP, look no further than the TS-451D2. It has four drive bays, an Intel processor, and everything you need to set up your very first home NAS.
