  • At CES 2013 Dave visited with the guys in the QNAP booth.  This provided the Home Server Show Podcast the opportunity to review the TS-269L in 2013.  The TS-269L was a 2 bay NAS and was fun to review.  For 2014 QNAP has introduced the QNAP TS-x51 Series and they have sent us a 4 bay TS-451 NAS to review and evaluate.




    The contents of the box are an external power supply brick and cord, 2 ethernet cables, an assortment of screws and of course the NAS.  There is also a Quick Installation Guide and a Getting Started Pamphlet.




    Interestingly enough you must have an internet connection in your home to setup the NAS.  QNAP does not send a disk instead using the start.qnap.com website and a Cloud Key to begin the system setup.  I will demonstrate the setup in another article.


    When I removed the NAS from the packaging the first things I noticed was it’s white and the case is completely made of plastic.




    Even the drive trays are now made out of plastic.




    The QNAP TS-269L I previously reviewed had stamped metal trays that felt like they were higher quality.




    However, I encounter in my own job a reluctance for customers to use a plastic part over a metal part and I know the plastic part will work fine the in application.  I have to give QNAP the benefit of the doubt here and we will see over time if the all plastic tray makes any difference.


    Looking at the back of the NAS you will see a huge 120mm fan is utilized to move air past the drives and electronics inside.




    Also on the back are 2 Gigabit RJ-45 Ethernet ports, 2 USB 2.0 ports, 1 USB 3.0 port, HDMI port and the power supply jack.


    The front of the box has a 2nd USB 3.0 jack and 4 Hot-Swappable bays.  The NAS is designed for 4 x 3.5” or 2.5” SATA 6Gb/s, SATA 3Gb/s hard drives or SSD.




    Let’s take a look at the specs for this box.


    CPU - Intel® Celeron® 2.41GHz dual-core processor (burst up to 2.58GHz)


    DRAM - TS-451: 1GB DDR3L RAM expandable up to 8GB

    Hard Disk Drive - 4 x 3.5” or 2.5” SATA 6Gb/s, SATA 3Gb/s hard drive or SSD


    1. The system is shipped without HDD.

    Weight - Net: 3 kg (6.61 lbs) / Gross: 4.3 kg (9.48 lbs)


    Power Consumption (W)

    HDD standby: 15.85W

    S3 sleep: 0.55W

    In operation: 31.07W

    (with 4 x 1TB HDD installed)


    Power Supply - External Power Adapter, 90W, 100-240V


    Secure Design - Kensington security slot for theft prevention


    Fan - 1 x quiet cooling fan (12 cm, 12V DC)


    So specifications are great but what does this mean?


    QNAP describes the TS-X51 Series as a High Performance Dual Core NAS with On-the-fly & Offline Full HD Video Transcoding.  These devices are capable of transcoding multimedia content on the fly including Full HD (1080P) videos to mobile devices and other computers.  Offline transcoding can allow the user to prepare a selection of optimized videos in advance for viewing on devices with smaller screen or when using a limited internet connection.  I will be writing a future article that examines how this works and does it affect the useability of the NAS for other tasks.


    The TS-x451 series is also the world’s first home NAS with an integrated virtualization solution.  The Virtualization app will allow users to effortlessly operating VM’s that run Windows, Linux or UNIX.  To provide this functionality a minimum of 2GB of RAM is required so QNAP has provided 4GB of RAM in the TS-451 for review.


    This is just the tip of the iceberg for all the capabilities of this NAS which provides features like streaming your videos via DLNA, Airplay and Plex.  Personal cloud storage is provided through the QSync app that I reviewed on the TS-269L.   I plan to explore and talk about many of these features and my experience using them as I use the TS-451 and learn it’s potential.


    One of the nice features of the QNAP devices is they all use the same QTS operating system.  Once you are familiar with the interface, features and apps you can work on any of the QNAP NAS devices and already be familiar with the interface.


    One additoinal note.  In the TS-X51 Series QNAP offers 2 bay, 4 bay, 6 bay and 8 bay devices.  If that isn’t going to be enough storage space for you the TS-X51 Series can be expanded with the additional of a UX-500P or EX-800P Expansion Enclosure.  These will add an additional 5 or 8 bays respectively of additional storage on the NAS using a USB 3.0 connection.  While the expansion boxes are not going to be reviewed at this time it’s nice to know these options exist.


    Leave me a note in the comments if there is something specific you would like to see or a question you have.


    My next step is to make sure I have some hard drives from the QNAP compatibility list http://www.qnap.com/i/useng/product_x_grade/?hf=old and start setting up the NAS.

    No I have never used a Synology. I will be at the 2015 Meetup with this box so that people can take a look at it and try it out.

    • I throw this out every once in a while.  Is anyone interested in writing up "semi-formal" reviews here on the forums?  I say semi-formal because they don't have to be pro level, just a good attempt at telling the story about the gear.  Something you have purchased lately.  You don't have to go buy stuff, just incorporate what you have already have purchased.  Hit me up with any questions.  You never know where it will lead!

    • D-Link has dropped a couple of new products and additions to their lineup of smart home gear.  Hold on because there is a lot of gear!
      Let's start with cameras.  D-Link has new Wi-Fi cameras, the Full HD Pan and Tilt Pro Wi-Fi Camera (DCS-8302LH) and Full HD Indoor and Outdoor Pro Wi-Fi Camera (DCS-8526LH).  These are not just new, and good looking cams, they can now perform people detection and glass break detection.  The new cameras also feature expanded ways for customers to save video, including ONVIF Profile S, which enables custom storage and streaming options to personal NAS devices, built-in storage microSD capacity up to 256 GB, as well as free and paid cloud storage options. 

      This year's camera models include both an indoor and an outdoor model. The outdoor model features a spotlight and siren that can be triggered when motion is detected, deterring potential intruders. The indoor model pans around to give a full 360-degree view of any room and tracks motion. Both include two-way audio. 
      Full HD Pan and Tilt Pro Wi-Fi Camera is the model (DCS-8302LH), available in Q2, 2020, and retail pricing will be $99.99.
      Full HD Indoor and Outdoor Pro Wi-Fi Camera is the model (DCS-8526LH), available in Q3, 2020, and retail pricing will be $119.99.

    • RESET Merch Shop
      Get ya Merch here!  I've created a T-Shirt shop with the famous RESET paperclip. I've pasted that clip on just about everything so you can wear it around town!  Cable bags, Coffee Mugs, T-Shirts, and more. 
      or you can get it it via
      Here is the main design.

      Below is a part of the order that I put in!  

      The Heather Grey above is the Extra Soft version and it is awesome.  I highly recommend the softness!    The "Chili Red" is the Tri-Blend and probably my favorite feel and color.

      This is the Zip-Up Hoody, Heather Indigo, Sponge Fleece, Men's, Large.  In my podcast I couldn't remember what style it was but it is Sponge Fleece. It's REALLY soft on the inside. Soft outside as well. The only problem is with the zip up hoody the logo is on the back. Regular hoody, it will be on the front.

    • OneDrive Personal Vault and expandable storage
      Microsoft's OneDrive has a few new features and options worth pointing out.  Personal Vault and Expandable Storage.
      Personal Vault is a protected area in OneDrive that can only be accessed with a strong authentication method or a second step of identity verification, such as your fingerprint, face, PIN, or a code sent to you via email or SMS. 
      Personal Vault gives you an added layer of protection for your most important files, photos, and videos—for example, copies of documents such as your passport, driver’s license, or insurance information—should someone gain access to your account or device.
      Plus, this added security won’t slow you down. You can quickly access your important documents, photos, and files with confidence wherever you are, on your PC, OneDrive.com, or your mobile device.

      Beyond a second layer of identity verification, Personal Vault also includes the following security measures:
      Scan and shoot—Using the OneDrive app, you can scan documents or shoot photos directly into your Personal Vault, keeping them off less secure areas of your device, like your camera roll.
      Automatic locking—No need to worry about whether you left your Personal Vault or your files open—both will close and lock automatically after a period of inactivity.
      BitLocker encryption—On Windows 10 PCs, OneDrive automatically syncs your Personal Vault files to a BitLocker-encrypted area of your local hard drive.
      Restricted sharing—To prevent accidental sharing, files in Personal Vault and shared items moved into Personal Vault cannot be shared.
      Taken together, these security measures help ensure that Personal Vault files are not stored unprotected on your PC, and your files have additional protection, even if your Windows 10 PC or mobile device is lost, stolen, or someone gains access to it or to your account.
      Expandable Storage
      If you are and Office 365 Subscriber you get 1 TB of OneDrive storage space with all the other Office goodies like Word, Excel, etc.  I know personally that I have gone over the 1TB limit and have always wanted to be able to add additional storage to my account.  Now you can!

      Pick and option and keep on hoarding, errr, I mean saving! Cancel anytime, upgrade at any moment.

    • Ubiquiti adds new items to the Unifi Line including UAP Flex HD and the Unifi Dream machine
      Ubiquiti has been busy.  There area ton of new items to recently released and I'm going to share two of my favorites.
      The UAP Flex HD and the Unifi Dream machine. The Flex HD is a mouthful of descriptors like most of UI gear is.  It's a 2Ghz 2x2 MIMO, 5GHz 4x4 MU-MIMO, POE, Indoor/Outdoor, multi mount, mesh point that is no bigger than a can of Coke.

      You will still need the Unifi controller although you can configure it with basic functionality with the Unifi App.  I've always found it's best to configure with your controller and then use the app as an add-on.  There are several mounting options that include sitting it on a shelf! That is something that Unifi has not had before unless you count the ceiling AP I have awkwardly mounted placed on top of a few books.  It can be found on the Unifi store for $179.
      The Dream Machine is an altogether different beast that I hope lives up to its naming.  This is the gateway drug, for lack of a better term, to the Unifi world.  The starter kit.  It is an Access Point, Gigabit Switch, Security Gateway, and the Cloud Key all in one package.  The latter being the most significant as this is something that has deterred new users from getting started with Unifi.  Requiring new users to purchase a $100 item just to run the AP's has been somewhat of a roadblock in the past.  Granted, that is improving every year with the ability to run it in the cloud, on a NAS, a Pi, Docker, MacOS, and of course Windows, it is still a barricade to getting up and running when manufacturers such as Eero offer simplicity in an app.

      The switch includes 4 LAN Ports and 1 WAN port.  All of which are Gigabit and security services such as IPS are rated at Gigabit speed. It's $299 in the Unifi store but I'm unsure how nicely it will play with other Unifi gear.  This may be a nice "first AP" with its built in Cloud Key if you can add additional units or other Unifi access points.
