QNAP Models Description: Choose the Perfect Fit

About QNAP NAS Parameters

Let’s review the main hardware and software parameters of a NAS that you can use to make your decision:

  • Hard drive bays: 1–30
  • Type of processor: Intel, AMD, Marvell, Realtek, AnnapurnaLabs
  • Operating System: QuTS, QTS, QES

Hardware Design

  • Rackmount — primarily used by enterprise NAS models. Rackmount devices have high performance, but also higher noise levels and no fans.
  • Set-top — small and affordable devices for your home. Set-stop devices have a low level of noise but no fans.
  • Tower — great for home, office or data center. Tower NAS devices have low noise and pleasant fans. You can place a Tower model on a table or shelf.

Interpreting the QNAP NAS Parameters

Let’s talk about processors. There are two main architectures for NAS processors: x86–64 and ARM. Processors of the x86–64 type assure better performance and compatibility with applications. On the other hand, ARM processors require less power, and they are more affordable. Intel and AMD offer x86–64 architecture processors. Marvel, Realtek and AnnapurnaLabs supply ARM architecture processors.

Tips for choosing a NAS Model

Here are a couple of things you should pay attention to while choosing the right NAS model:

  • Make sure your NAS model supports an expansion unit called “expansion chassis” or “expansion enclosure”. This expansion unit comes in handy if your disk bays get full. You can use the expansion unit to install additional disk drives in your NAS device.
  • Verify the number of disk bays you can install and the number of disk drives that you can add to the NAS device. Additional disks for NAS are sold separately. The original QNAP NAS devices do not include disks. To install or uninstall disks on your NAS device, use hot swap.

More about NAS features

USB ports: You can connect a NAS to your computer with a USB 3.0 micro-B port. However, connecting a NAS device to a computer is different from connecting a USB HDD to your computer. With a NAS device, you should rely on a network interface instead of disk drives (F:), (J:), and (K:). To connect via network interface, use a virtual switch on a NAS device. Connect your NAS via the IP address of the NAS that you have connected to your computer via USB. This feature is called USB QuickAccess.

  • Balance-rr (Round-Robin)
  • Active Backup
  • Balance XOR, Broadcast

There are numerous QNAP NAS models. QNAP doesn’t offer an easy classification that can help quickly identify a device. QNAP devices are categorized by series. The first number in the series tells you the maximum number of disks you can install on your NAS. To see the full list of NAS models, click here.

QNAP NAS offers devices for:

  • Personal and home use. These units are great for multimedia streaming, collaborative editing and backup.
  • Small and medium businesses. Used for storage, file compression, deduplication, collaborative editing and remote backup. Can be optimized for a virtualization server.
  • Enterprise. You can create a cloud-based NAS and run it on a public cloud or on-premises. Use dual-NAS for backup, online deduplication and as an all-flash storage solution.

QNAP Storage Features

Now let’s go over the main features of QNAP storage:

  • Supported protocols: HTTP/HTTPS, Telnet, SSH, SNMP, SMTP, SMSC, LDAP.
  • Data sharing protocols: SMB (CIFS), NFS, FTP, SFTP, TFTP, AFP, iSCSI.
  1. Record videos from IP cameras to disks
  2. Use a web browser to view the videos in real time
  3. Watch videos from a monitor connected to a QNAP NAS
