QNAP TVS-1282T3 Ultra-High Speed 12 Bay (8+4) Thunderbolt 3 NAS/iSCSI IP-SAN. Intel 7th Gen Kaby Lake Core Thunderbolt3 Port x 4 and 10Gbase-T x 2

QNAP announces this product with throughput: (mac) read/write 1171/1437 MB/sec and (win) 1973/1291 MB/sec. But nothing far from real world. Actually when I asked to QNAP people for the details of that ideal testing environment, about brand/models of the computers, operating systems, Etc. to achieve such high throughput, they refused to declare how in the real life it is possible to achieve that transfer rates, what leads me to think that those are fake numbers.QNAP Engineers never have an answer, they connected to my computer MANY times to "analyze" the problems and find why I was getting very low transfer rates, and they visited all menus that was not useful to fix the issue, and they visited the same useless menu over and over again, with no benefit nor solution.But I find myself the cause of several problems, but even fixing them, the QNAP's transfer rate is still VERY low.The transfer rate is VERY sensible to many operating systems and software factors. Al my tests were done with the same only one 43GB file.Windows Server 2016 (SMB). After reinstall from scratch the operating system (interrupting my production) I discovered that the ideal transfer rate is read/write 900/900 MB/sec. Kaspersky Anti-Virus lowered the read transfer rate to 600 and after tuning, it reached an average of 670 MB/sec. Kaspersky people worked on my problem in a very detailed way and found a bug which is being fixed now by its developers, but there is not date for the patch releas. I uninstalled Kaspersky to continue with my tests.These ideal numbers are just reported by Black Magic Speed Test. In real life, my tests were:Copy from Win->QNAP = 420 MB/sec.Copy from NAS->Win = 580 MB/secWhat it is non logical is that, From QNAP folder A to QNAP Folder B (through the WinServer), the maximum transfer rate was never higher than 350 MB/sec.Other issue with no fix as by now is that VMWare Workstation 15, cannot work properly with QNAP SMB shares. It continuously returns privileges errors, even when the QNAP share has read/write privileges.Mounting an iSCSI block device VMWare Workstation works flawlessly, but what iSCSI shares are 20% slower than SMB shares. This is absolutely unexpected because iSCSI protocol has headers much smaller than SMB. I never ever saw any storage server which reported lower transfer rates with iSCSI than with SMB.MacBookPro (AFP). I tested with 10.10.5, 10.12.1, 10.13.1, 10.13.2 10.13.3, mounting the same QNAP Shares by AFP, and Transfer rates in 10.10.5 were less than 200 MB/sec. They got higher in 10.12.1 and the highest ones was gotten with 10.13.1 with write/read 390/760 MB/sec. But my main app in my Mac is only certified for 10.13.3. I installed 10.13.2 update which got slower rates and 10.13.3 which finally has read/write 313/544 MB/sec. It is clear that the bugs that Apple fixed with that updates, destroyed something else that caused this impact in the read rates... or that QNAP OS has certain incompatibility with the macOS Updates.RAID types: I tested with RAID 0 (no redundancy at all), RAID 10, RAID 5 and RAID 6. Surprisingly there was no noticeable difference in transfer rates. This is non logical because RAID 0 must show a MUCH higher transfer rate than any other RAID type with any level of redundancy.In any case, be prepared to get any transfer rates (you cannot know it when you purchase this QNAP device) bu NEVER the transfer rates that QNAP announces for this storage model.Noise: QNAP says that this device makes a 21.6 dBA of noise. The metric I got was 35 dBA. This metric was taken early in the morning with several client machines connected but before workload from the client machines started that day.Encrypted Folders: This feature is real but with an unexpected limited scope.* Individual users cannot enter a password and access the encrypted folder to open it only for that user. The encrypted folder can only be opened directly in the admin interface of the NAS, and then it is opened for all users who have access to it.* Someone who have access to the admin interface (without the need to know the passwd) can download the key to open it again anytime it want after that.* An encrypted folder cannot be created "inside" other folders. They can be created in the "root" of the device only. You can "modify the path" of this encrypted folder and see it inside that path, but it ALWAYS also appears in the "root". QNAP's Tech Support says "that is is only a link but there is no way to prevent that link to appear".Update 2018-01-21I purchased a QNAP QSW-1208-8C to connect using Port Trunking. The throughput would never increased with this config. Money sent to the trashcan.I purchased and installed the 256 GB Internal Solid State Drive SSD SATA M.2 2280 SSD-M2080-256GB-A01 to use it as cache in my NAS. After a couple of session where the QNAP's technical support engineer connected and configured himself the cache device, my throughput access data in the NAS was actually lower (slower). QNAP engineer simply said: "I don't now why", and did nothing. Again money sent to the trash. Now I have a $200 M.2 device that I don't need and that I can't return because it works. What does't work as promised is the QNAP device.Voice announcements:I have my MacBook Pro (High Sierra) Permanently connected to QNAP NAS. When I put my MAc to sleep, QNAP announces (by voice): "Thunderbolt device has been disconnected". But after a few minutes, it announces: "Thunderbolt device has been connected" and repeat the same "cycle" announcing connected and disconnected over and over again, all the time that Mac is in sleep mode!Relevant info about my stuff:My QNAP:Model: TVS-1282T3CPU: Core i5 (never has used more than 15%)RAM: 16 GB (never has used more than 18%)HDDs: 8 x 6TB Seagate Ironwolf Pro ST6000NE0023 EN02RAID Volume: RAID5 (No spare)Data Volume: ThickMy Windows Server:CPU: 2 x Xeon E5-2650 (never used more than 10% in the test)RAM: 64 GB (It used until 43 GB for "cache" when copying from NAS to Win local disk)Network: Intel Ethernet Converged Network Adapter X540-T2 (10Mbps)My MacBookPro (2014):CPU: Core i7 (never used more than 10% in the tests)RAM: 16 GB (never used more than 20% in the tests)Network: Thunderbolt 2 (20 Mbps)

This thing is loaded with features. I have had some problems with access via the Thunderbolt 3 from PC and Mac but that just may be my lack of knowledge.

Everything that I've played with has worked well, but I've repeatedly had the network transfer speeds go from 1GBps to 100MBps, without me having changed anything. I've gotten no help from QNAP other than "check your disks and back things up", and there isn't any documentation on making it work consistently.Wouldn't recommend this for if you need any reliably fast ethernet connectivity to it. Frustrating and disappointing.

It's a total beast. This is my second QNAP NAS. First one was a TS-869Pro with 8x3TB WD RED NAS drives. It ran flawlessly for 6 years or so.This one is so much more complex...it can do SSD tiering, cashing, auto -tiering with Q-Tier, Virtual machines, run a Plex Server, Roon Server, TwonkyMedia, and a whole lot more.I set up two 1TB Crucial M.2 SSD's for my operating system / programs (QNAP / QPKG apps) in RAID 1 (THICK) and then I set up two 2.5" Crucial 1TB SSD's in RAID 1 (THICK) in a Q-Tier managed Storage Pool with 3x 8TB Seagate IronWolf NAS drives in RAID 5. QTier is working flawlessly so far. I also have 4x3TB WD Red NAS drives in a separate RAID 5 array so that I can use QVR Pro to write to that array for home Surveillance (9 cameras). That array is not part of the Q-Tier managed storage pool since performance is not a player there.The piece de resistance? This thing has 2x 10GbE network ports. I set up a virtual switch with both of them (and one of the 1GbE ports)...I plugged the 1 GbE port into my router for internet, and the other two plug in to some PC's I have. I installed a QNAP QXG-10G1T 10GbE Network Interface Card (NIC) into each PC and I'm getting 3.5 Gbps over regular CAT6 cable in my home when writing to/from the NAS using that card. Be sure to install the latest Aquantia drivers for that card if you buy one, the drivers that Windows installs by default are not Win 64 bit compatible and the card won't work without the latest (December 2018) drivers or newer.So...I basically got a free 10GbE switch to hook up to two computers with this NAS (cheapest I've found for a stand-alone 10GbE switch is also a QNAP at just under $600.00; NetGear are even costlier as of Jan 2019).So far, zero issues, it is lightning fast, and I love it. Would definitely recommend this unit.

I bought the i5/16GB/T3 version and installed 8 Ironwolf 10TB drives. Over 10GbE ethernet from Win10 clients, I usually get about ~1000-900MB/s read/write rates which would be about the max (ie ~7200 megabit in a 10,000 megabit pipeline). Over T3 to my PC (which I have a board that only has a 20Gbps T3) it is generally faster but not by much but will occasionally "burst" past 1000MMB/s. You have to think for 8 hard drives that have max ~200MB/s read/write rates apiece, a 900MB/s transfer rate in RAID6 is not bad. I have been running the unit for about a year, never given me any problems. Always stable and reliable. I think if I were running SSDs, would double the read/write rate.EDIT:Purchased 4/2018. Since that time, the unit has operated constantly and without fail, never experienced a single problem. QNAP makes a great product. This has been one of the best pieces of "high tech tech" I ever bought.
