Multimedia Console – one portal access point to manage media access, searching, indexing and transcoding on your NAS device. This is made even easier to achieve when you loo through the official QNAP QM2 upgrade card range. The cards, with several new PCIe4 entries, allow to to scale things up in your storage even further with some featuring 4x PCIe 4×4 M.2 NVMe SSD bays or even a 2x 10GbE and 2x PCIe4 M.2 NVMe SSD Combo card. Currently there is no sign of a Thunderbolt 3 or Thunderbolt 4 Card (as seen in the TVS-872XT or TVS-h1288X), but this might well be down to the continued shortage of Thunderbolt components right now (as the Intel Core 12th Gen family has complete TB4 Compatibility).

Intel® Core™ i3-12100 quad-core/8-thread processor (burst up to 4.3 GHz), 16 GB DDR4 (1 x 16 GB) memory HMB = Host Memory Buffer, using part of your System memory, to speed things up and hold them more consistent, which means with my 32gigs of DDR4 3600CL16 RAM ive no problem with that.) QTS vs. QuTS, i get QuTS is the new QNAP OS and probably the only one that will be left in few years. I guess i should go with it to play the long game. Any gotchas i should be careful with considering my uses/needs? I know i can't add a disk to a storage pool with QuTS but since the NAS will be fully loaded from day 1, that is not an issue for me. I don't think I need any SSD caching as I don't use any database/VM/video editing solution. I heavily rely on Qfile and Qget apps on iOS to remotely access my current NAS, any restriction or loss of feature if I go with QuTS?Virtual machines and containers - Host multiple virtual machines and containers with optimized resource utilization. If we skip over the difference in the actual traditional CPU power (which is expected if you were comparing a Pentium and i3 versus an i9), the hurdles start when you notice that the TVS-h474 has Gen 3×2 M.2 slots, whereas the 6-Bay and 8-Bay have Gen 4×4 – so potential bandwidth of 2,000MB vs 8,000MB/s. The same goes for the main PCIe upgrade lanes, with the 4 Bay having that massive PCIe 4 x 16 slot, but the 2nd slot is another Gen 3 x2 2,000MB/s slot. These are very small details, but they could have been easily avoided by either fixing the TVS-h474 with an i3 minimum OR just releasing the series in a fixed CPU=Bay standard (as observed in the TVS-X72 and TVS-1282 ranges). With 3 version of the 8-Bay, two of the 6 Bay and the 4-Bay being very overshadows, the narrative and presentation of the range gets a little messy. Then you can take a closer look at the CPUs themselves and how they scale up. Highly-reliable ZFS-based storage with PCIe Gen 4 expandability for 10/25GbE connectivity, M.2 NVMe SSD caching and multi-threads processors for virtualization applications

The actual number of virtual machine instances may vary by the memory installed on Comparing the full range of five early 2022 released 12th Gen Intel Core processors available, it becomes abundantly clear that the 8-Bay system and it’s options for the i5, i7 and i9 are the most powerful option, scaled according to it’s larger capacity for storage and throughput (with a higher equipped 350W PSU compared with the 250W in the 4/6-bay tiers). Interestingly, with the exception of the Intel Pentium Gold processor, the rest of the processor family has a hugely impressive 4-5Ghz turbo/burst performance level available per core and the 6-16 Core architecture (and upto 24 threads) means that everything from high-performance database creation, heavy Virtual Machine deployment, video editing and large scale surveillance is going to be an absolute doddle! Intel® Pentium® Gold G7400 dual-core/4-thread processor (burst up to 3.7 GHz), 8 GB DDR4 (1 x 8 GB) memory Intel® Pentium® Gold G7400 As far as we can tell, this new family of enclosures will be the very first to utilize 12th Gen Intel processors. Sure, 13th Gen chips are just around the corner and will likely yield better performance at a similar power draw, but compared to vastly outdated processors one is able to choose in NAS enclosures (like the superb QNAP TVS-672X), the 12th Gen series will offer a colossal uplift in performance.which also beats the SN770 (and all the other cheap options, like the NV2 or P5plus) that on top of that only comes with 2TB max, so that wasnt an Option. I was thinking RAID 50 would be a bit better than RAID 5 considering the volume size. RAID 6 is appealing for fault tolerance but no performance gain compared to RAID 5, unless i’m wrong. Note: At least 1 GB RAM is required. The maximum number of channels supported varies by NAS model, network configuration, and camera settings.

As we dug into the specs, the memory was very interesting indeed. Alder Lake supports DDR4 or DDR5, but these NAS units support DDR4 SODIMMs. It also seems like QNAP is using non-ECC memory by default, but enables ECC on this platform. Here is the slide we found on that: QNAP TVS Hx74 ECC Memory Support Core i5 and Core i7 variants of TVS-h874 come equipped with dual Transcend TS2GSH64V2E3 16GB DDR4-3200 CL22 modules as standard, and this can be upgraded to a maximum of 128GB. Do note, however, the underlying Intel H670 chipset does not include support for ECC. The system ought to boot just fine with ECC memory installed, but error correction would sadly be disabled. QuTS hero The maximum number of channels supported varies by NAS model, network configuration, and camera settings. For more information, visit https://www.qnap.com/solution/qvr-face/en-us/ Despite a few constraints, TVS-h874 is easily the most powerful turnkey NAS we’ve tested, and such potent hardware requires forward-looking software able to harness that potential. To that end, QNAP’s setup wizard begins by giving users a choice of operating systems; QTS, a mid-range platform most readers will be familiar with, and QuTS hero, a ZFS-based OS geared for business.

The price is high, but this well-endowed desktop NAS delivers enterprise-class storage features

Space Saving Efficiency – Inline data deduplication, compression, and compaction reduce file size to conserve storage capacity and optimize performance. I am well aware of how much I have been ‘banging the drum’ about PCIe 4 architecture in this review, but I cannot overstate how future-proof this makes the QNAP TVS-h874 NAS! It is a shame that the TVS-h874 suffers something of a presentation hurdle for the less technically versed who need to take some time to bone up on the range of specs before choosing the right model, but that does not really detur from the fact that the TVS-h874 NAS arrives with the best desktop NAS hardware I have ever seen! Let’s discuss those software and services found in QuTS and QTS 5 that are included with this NAS server. A virtual private network (VPN) allows secure access to network resources and services across public networks. QVPN supports creating a VPN client, using the TVS-h874 as a VPN server, and WireGuard® VPN service with an easy-to-use interface for setting up a secure connection. The PCIe expansion slots are on the other side of the motherboard. Here is the rear view annotated with features: QNAP TVS H874 Rear View In a well ventilated ATX case I have not seen any NVME heating issue, just slightly warmer than a mostly idle SATA 2.5″ SSD.

Flexible PCIe Gen4 expansion - PCIe slots allow for installing 2.5/5/10/25GbE adapters, QM2 cards, or entry-level graphics cards to increase application performance. Warning: Using unsupported modules may degrade performance, cause errors, or prevent the operating system from starting. The QNAP TVS-h874-i9-64G version of this series arrives with two 10GbE ports by default (something that I think is a bit of an oversight on the i5 and i7 models) but even then, the combination of 8 bays of SATA storage, 2x M.2 NVMe PCIe Gen 4 Bays and potential to add PCIe 4 NVMe storage and/or Network combo cards means that this system has TENS OF THOUSANDS of Megabytes of internal performance potential. So how much of that can actually be realized externally? Well, going by QNAP’s published performance figures (as I personally simply do not have the hardware environment to simulate this), we can see the following:The connectivity that the QNAP TVS-h874 NAS arrives with is all good, if fairly standard stuff (unless you opt for the Intel i9 version – more on that later). As mentioned earlier, there are a plethora of fans on the rear of this 8-Bay, but when it comes to the default connections on offer, there is only really three. It is in it’s long term scalability that the connections of the QNAP TVS-h874 that things start to get a little spicy. Intel Core i5-12400 six-core/12-thread processor (burst up to 4.4 GHz), 32 GB DDR4 (2 x 16 GB) memory For more affordable 4TB drives for gaming and/or content creation, that still deliver good performance and dont cheap out on the quality and longevity, ive opted for the Lexar NM790.
