This 24-bay NAS is one of the fastest in the world

Main features of this ultra-fast NAS

Rack-type NAS servers are usually very powerful, however, the main manufacturers such as QNAP or Synology have this type of servers of all ranges, in order to meet the needs of their customers. Today we are going to show you the latest NAS server that QNAP has launched, a top-of-the-range model that incorporates everything you need to be one of the fastest in the world, and one of the ones that can provide the most storage thanks to its 24 bays for hard drives.

CPU, RAM and Flash characteristics

This new NAS server has a very powerful AMD Ryzen 7 3700X processor, this processor has 8 cores and 16 threads of processing, at a speed of 3.6GHz with a turbo speed of 4.4GHz. This model uses a 64-bit x86 architecture, in addition, it has a floating point unit and also the AES-NI encryption engine to transfer data with protocols that use data encryption and AES as a symmetric encryption algorithm.

This server is sold with 32GB of DDR4 UDIMM RAM, in two modules of 16GB each, however, it allows you to have up to 128GB of DDR4 RAM (4 modules of 32GB each), so we will be able to use a large number of virtual machines with Virtualization Station, host hundreds of microservices in Docker containers and much more. This RAM memory is ECC type, because this NAS server has the QuTS hero operating system, an operating system that uses the ZFS file system, one of the most advanced that we can currently have on a server.

Finally, this NAS server has 5GB of flash storage for the protection of the operating system with double boot, ideal in case we have any problem in the update of the operating system.


This NAS server is one of the most complete on the market, it has a total of 24 bays to accommodate 3.5 “or 2.5” hard drives, although it is also compatible with 2.5 “SSDs, which we can use as storage or as SSD cache to accelerate the overall performance of the NAS server. Of course, all their hard drive bays are hot swappable, and compatible with all large capacity hard drives and SSDs on the market.

Although this server does not have SSD caching with M.2 NVMe, what we can do is buy expansion cards from QNAP to provide this feature to the NAS server. Thanks to the incorporation of a total of 4 PCIe 3.0 ports of different bandwidths, we will be able to install QM2 cards with M.2 NVMe, and we can even buy 10G and 25G network cards to expand the possibilities of the server.


The connectivity of this NAS server is very complete, the first thing we have to say is that it incorporates a network card with two 10Gbps SFP + ports, therefore, we can achieve a bandwidth of 20Gbps if we use Link Aggregation. We also have two Gigabit Ethernet ports for the LAN, with support for Link Aggregation. Of course, all ports have support for 9K jumbo frames.

This QNAP TS-h2477XU-RP server has a total of 4 USB 3.2 Gen 1 5Gbps ports, that is to say, the typical USB 3.0 of always. It also has one USB 3.2 Gen 2 Type-C port at a speed of 10Gbps and other USB 3.2 Gen 2 Type-A port at a speed of 10Gbps.

Regarding the PCIe 3.0 ports that this high-performance server incorporates, we have the following expansion slots:

  • Slot 1: PCIe 3.0 x4
  • Slot 2: PCIe 3.0 x8 or PCIe Gen 3 x4
  • Slot 3: PCIe 3.0 x8 or PCIe Gen 3 x4
  • Slot 4: PCIe 3.0 x4

In case slot 1 is occupied, slot 2 will work at PCIe Gen 3 x4 instead of PCIe Gen 3 x8. If slot 4 is occupied, slot 3 will run at PCIe Gen 3 x4 speed instead of PCIe Gen 3 x8.

Thanks to these PCIe ports, we will be able to install network expansion cards to have a 25Gbps speed port, we can install M.2 NVMe cards to use them as SSD cache, 10GBASE-T Multigigabit network cards and even WiFi 6 cards and USB 3.2 Gen 2 expansion. Thanks to this connectivity, we will be able to expand the connectivity of this equipment and have a greater bandwidth in the professional local network.

Other features

Other characteristics of this model are that it needs a total of 4U in the rack to be installed, it measures 176.15mm high, 481.04 wide and 672.02mm deep, with a weight of 22.66kg. This model has two redundant 800W power supplies, ideal in case one of them stops working. The consumption at full performance is 144W, it has a total of 4 92mm fans in addition to the fans of the power supply. The sound level is 27.5dbA.

As you have seen, this NAS server model is one of the most powerful, fastest and with the largest storage that we will be able to have on a server. The QuTS hero operating system has the same configuration options and services as always, in this regard nothing has changed.
