TVS-871 vs 873

[Trexx]

Really the i7 upgrade option is the only real advantage on the TVS-871.

Amazon is showing the (i5) 871 @$1,717 (8gb) , 873 @$1,249 (8gb).

Always buy your own memory for doing upgrades as it is a lot cheaper. Remove 3 screws on the back (at least for the x73) and you have easy access to memory.

I have (2) of these kits in my 673. https://www.amazon.com/dp/B014R8JRRW/

i have the same mem. also, except 2 X 16 ...

UX speed at 50% big disappointed for users and not made clear.

50% over local NAS storage, or over the glossy paper 5 Gb/s USB 3.0 numbers, or over the 1st gen 6 Gb/s SAS REXP, or over the 2nd gen 12 Gb/s SAS REXP? Expecting any of these does provide full speed for hot data is a little bit .. naive. Yes, I was kind of disappointed when running the first tests on the UX enclosures.

As for ES1640DC v2, yes if you assume 6Gb/s version never existed. Basically v2 a correction of lots of mistakes in the original ES1640DC launch. Still managed to mess up v2 version with 10Gbe Intel SFP+ card drivers that don't perform properly.

No doubts, disappointing the QES drivers for the Inhell X710/XL710 are still not ready and available. The situation reminds me somehow to the Inhell's failure to follow up their promises they had to the world and their customers (this is finally QNAP and us...) with the disappointing Cedarview GPU support...

Drivers for FreeBSB are available for the x710 cards so I'm not sure whether this is Intel's fault.
Other 10GbE SFP+ cards are available that Qnap could use such as Broadcom, Mellanox.

This is my 2 cents -
The TVS-873 looks great, but it looks like a new version of the 863+.
For video clients, (for all clients) - they want to spend as little as possible - that's the bottom line.
But of course, video clients are not storing accounting or data base data - they are storing huge video files, so everything is terabytes of data.
I always push the TVS-EC1680, but it's too much money, so I usually choose the TVS-871T, simply because I can expand with the thunderbolt 2 cable, and the TX800P is only $899 at on line retailers.
I just read (in this thread) that the REXP with the SAS expander will be available for the 873, but I can't see anything that actually says that. And no one wants "cold storage" with USB3 or USB 3,1.
They want their data - ALL their data, all the time, at a moments notice. The idea of tier 2 storage is a nice fantasy, but for these small production companies, they want it all, at the cheapest possible price.
So at this moment, the "cheapest" realistic product is the TVS-871T. Yes, the 873 looks amazing, and is about $1000 cheaper, but unless the REXP is a reality (maybe it is, and I am ignorant of this) -
then the 873 is for a client with absolutely no budget (heck, I've installed TS-831X for clients with no budget, and it works) - but for a 2017 installation for a pro video client that will absolutely run out of
room with only 64 TB of usable data (while he shoots 4K and 6K video) - the TVS-871T is still the best "bang for the buck".
With that said, I bet I install a ton of TVS-873's and if in fact they wind up supporting the REXP with SAS expansion - then yes, it may be the end for the 871T.

AND - I am completely ignorant of the new Thunderbolt 3 QNAP's they showed at CES 2017 last week.
AND - yes, the TVS-1282 is a great box, but every penny extra (including the 4 SSD's) is that much more money that clients DO NOT want to spend.

Hi Bob. The x73 info on the REXP is listed in the 4.3.2 20170104 beta release notes. Hernan also I believe mentions it in the Qnap YouTube video on the x73 family.

As for comparison to x63, it is based on a 3rd gen AMD Soc, so yes it is evolutionary just like most of Intels cpu's of late.

I'm also trying to compare TVS-871 and TVS-873. I'm curious about comparing the two from a 4K video transcoding perspective. Can either actually transcode 4K video and if so which model/config is best?

[dolbyman]

live transcoding ? how many simultaneous clients?
4k codecs used ? (codec with options,hevc, 10bit, hdr etc)
what transcoding? for plex or filestation ?

more info needed

[berrybok]

live transcoding nice, not necessary. 2 simultaneous clients preferred, 1 workable. I have ROKU 4 which supports H.265 & VP9. I am planning to use PLEX.

Assuming all your video's are capable of Direct Play in Plex, then either box would do just fine. If you need subtitles, then that generally kicks in real-time transcoding requirements.

Things to remember, x71 family is an older platform and as such has less memory expansion (16GB vs. 64GB) and slower memory (DDR3 vs. DDR4) compared to the x73. It also doesn't have the internal m.2 SSD options.

Those aren't a real big advantage for streaming, but if you are running other workloads as well (VM"s, Docker, etc.) then they can come in handy real quick.

As for real-time SW based 4k video transcoding,Plex says that you need a cpu passmark around 8,000 for a single stream.

You would need to look at the new Ryzen based TS-x77 family or an i7 based TVS-x71 or x82 models to hit that.

If you need it today, I personally would go with an TVS-x82 model over the older TVS-x71 model.

The TS-x77's aren't quite shipping yet, but they are supposed to ship yet this quarter based on QNAP's latest information.

[berrybok]

Thanks for the excellent feedback. Earlier today I learned of the anticipated TS-X77's and assuming my budget can handle it, I'll likely wait.

Interesting. Was leaning towards the 873e, but of course, would need to be able to expand it sometime in the future, seamless without to much performance loss.

And any word if possible to use a Thunderbolt PCIe 2.0 or 3.0 card in the 873e and expand with a TX800 ?

Kinda ridiculous having to buy the 1282-T3 and pay twice the price of the 873e, only to get expandability with Thunderbolt T3 when there are T3 PCIe cards available for USD$80!

As stated in this thread, QNAP does state that the x73 series should get REXP support. Here is from the release notes:

"QTS4.3.2.0050 Public beta 2
( 2017/01/05 )
QTS 4.3.2.0050(Public Beta2) Build 20170104

[New feature]

- Added support for the linear expansion of static volumes through expansion units.
- Added new disk icons in Storage Manager to help distinguish between HDDs and SSDs.
- Network & Virtual Switch now provides Basic Mode and Advanced Mode to meet different needs.
- Added the option to restore files to the specified paths in Snapshot Replica
- Added support for creating read/write cache with single drive, RAID 0, RAID 1, and RAID 10 configurations.
- Added support for the USB 3.1 PCIe card USB-U31A2P01 on the following NAS models: TVS-463/663/863/863+, TS-563, TS-463U/863U/1263U, TVS-471/671/871, TVS-471U/671U/871U, TVS-682/882/1282, TVS-682T/882/1282T, and TES-1885U/3085U.
- Added support for installing up to 4 REXP-1000 Pro expansion units on the TVS-x73 series.
- Users can now obtain support for exFAT file system through purchasing the exFAT driver license."

Also here under the expansion options, REXP is listed as an option for 873 :
https://www.qnap.com/en/compatibility-e ... l=tvs-873e

The 873e is officially listed as working with the SAS 12G2E card, so this makes the 873E expandable using 24Gbps SAS / REXP.

Even if the TVS-873 is not specifically listed as a compatible NAS under the card specs:
