QNAPTL-D400S 4 Bay SATA 6Gbps JBOD Storage Enclosure. PCIe SATA Expansion Card (QXP-400eS-A1164) Included

I use it with a QNAP 464 and see little performance drop with it. Although it can’t support hardware raid, the software RAID has been flawless thus far. Just make sure to follow the documentation.If you do not plan on connecting this to a QNAP machine, be weary. The software’s designed for QNAP and they have a history of not being as reliable on other hardware. This is not the the fault of the product though, it’s built for a QNAP NAS.This expansion is designed well, and I’m grateful for it. Stacks perfectly on top of the existing NAS.

Bought to expand a 6-year-old NAS TS-453Be. Easy install. Install PCI card into NAS, connect cable, install drives. Upon power on, it was instantly recognized. was able to create storage pool & shared folders as normal using "Storage & Snapshots" in QTS. Installed 2 8TB WD Red Plus Drives configured as JBOD as enclosure will house non-critical heavy read/write storage for Blue Iris security cameras, and Plex OTA TV DVR Recordings. It works seamlessly with my NAS and I couldn't be happier. Works as expected.

The QNAP TL-D800S claims to support running on Ubuntu or Windows, connected to a PC rather than to an existing QNAP NAS. But that's only partially true. Linux support is limited to Desktop Ubuntu for the QNAP Manager app, and it can not run on a server without a GUI. There is no command line interface available, and making matters worse the Linux app can not update the JBOD device's firmware. It's not really "linux support" in a meaningful sense if all it's doing is reporting SMART data in a GUI.The unit I received is causing my Debian system to freeze whenever I attempt to write data to any of the disks, so I'm unable to use the device in the first place. The search feature for the knowledge base is incredibly lacking, the forums need to be searched using an advanced google query, and they offer minimal support since most people seem to get frustrated and give up.I'm also pretty disappointed with the quality of the disk trays. The plastic drive retainers are okay at best, but I would NEVER trust them to hold a drive outside of the chassis. Fortunately they ship screws with the accessory kit. But the latch mechanism is very thin plastic, they keys are very thin plastic, the locks I guess are okay for just making sure you don't accidentally pull the latch open? In any even, the latch doesn't have a release button so there isn't anything positively keeping it in place. The tray rails also get bound easily in the tray slots in the chassis, so tilting the front of the drive downward when installing is necessary.The SATA adapter included is pretty low spec as well, and doesn't actually offer enough PCIe lanes for the throughput that the SATA links can support. This won't matter much if you're using HDDs, but if you're installing SSDs, you should probably provide your own SATA/SAS HBA with two SFF-8088 ports.One good point, if I have to give one, is that internally everything is a PCB that is socketed to other PCBs. This means there are no loose data cables inside the chassis getting chafed or otherwise damaged on sharp corners. There's also little or no room for the sockets to come partially unseated in transit, so if your unit actually functions, it's unlikely you'll have to re-seat anything.

Can get a bit "rumbly" so put it on a stable surface or on a rubber matt. Otherwise, it's awesome. Use it for my unraid setup.

The speed-adjustable main fans are fine (you can't hear them), but the power supply contains a tiny, non-adjustable screamer of a fan than makes this unit completely unusable in any closed room where you want to comfortably work.The 24db number in the specs is a lie. Actual measured noise is 44db, at an unpleasant high pitch.

Plenty of drive space and it just worked with qnap nas I have.

Best all-in-one miniSAS enclosure. Works with Linux out of the box. Have it installed in my home r630.

After having received this 15 days ago, I've been on a quest for Linux drivers for the TL-D1600S. Without the driver, this product is about as useful as a $1100 doorstop. On the QNAP download site, neither the TL-D1600S nor the included QXP-1600eS HBA card has any downloads at all, let alone drivers (Windows or Linux). I initially contacted QNAP customer support 14 days ago, and they still have not been able to provide suitable drivers. The heart of the HBA card is a Marvell chip; I haven't been able to find (Windows or Linux) drivers from Marvell either.The product website at qnap.com advertises support for Windows, "Linux with Kernel 3.10 ~ 5.0", and "officially supports Ubuntu 18.04.03 (Kernel 5.0)". Despite this, the QNAP download site has absolutely nothing available for the TL-D1600S nor the included QXP-1600eS HBA card. Go to download.qnap.com, choose the product type "NAS / Expansion", then "16 Bays", and see that TL-D1600S is missing from the model list. Similarly, if you choose product type "QXP Expansion Cards", you'll see model QXP-1600eS is missing.After seeing this, I contacted QNAP customer support. (I had to file the ticket under TL-D800C. The TL-D1600S wasn't even available as a support option!) It took them 11 days and two levels of escalation before they finally came back with a steaming pile of driver binaries for ancient (kernel 2.6) versions of RedHat and SUSE distributions, a far cry from the advertised support for kernel 5.0 and Ubuntu!Even more discouraging is that I can't find any drivers (Windows or Linux) for the HBA card's chipset. The QXP-1600eS is based on the Marvell 88SE1475. Marvell's product brief for the 88SE14xx claims to have "Windows and Linux reference drivers" and a "Linux GPL open-source driver", but couldn't find downloads for any of this.After half a month of struggling with this, I've lost patience and I'm returning this glorified doorstop. It's a shame, since I quite liked the physical design. Even if I could get the device working today, this experience does not instill confidence that driver support will be maintained as the Linux kernel evolves.Stay away if you plan to use the TL-D1600S with Linux! You *might* have better luck with Windows, but you'll have to go through support to find drivers, and probably roll the same dice I did. I checked, and the drivers aren't built into Windows 10, either. I can't find any suitable drivers available, for neither Windows nor a modern Linux, from neither QNAP support nor QNAP's website nor Marvell's website.
