QNAP TL-R1200S-RP 12 Bay 2U Rackmount SATA 6Gbps JBOD Storage Enclosure with Redundant Power Supply. PCIe SATA Interface Card (QXP-1600eS) 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.

Missing screwd for the side.

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.

First off ignore the comments. Assuming you followed the included diagram and installed the device management software the drive is included with that software. I plugged this into windows and it "just worked" But I did not purchased this storage shelf for Windows. I have a TVs-1282T3 who's storage I needed to expand. Install is easy. But be 100% certain you have the SAS cables labeled as the SAS cables control specific groups of drives. Reference the diagram for what is cable 1,2,3,4 on the shelf. On the controller it shows 1,2,3,4 on the card's back. Its difficult to see once installed so take note of this before you install the card.Then just plug in the cables to the correction location, power on the shelf, wait 2 minutes. Then power on the host.Throughput is fast, but it seems it is a bit slower than what is on the host even though in theory the drives I installed are faster. (Seagate Ironwolf Pro's 10TB 7200 drives.)Also not a big fan of not being able to control the fans from the software. There is a switch on the back that you can set the fans to slow, high, or auto. I left it on auto, As I was building the RAID group I got an alert that one of the drives reached a temp alert threshold. As the NAS's software can't control fan speed it didn't change anything with that alert. Went and changed the switch to fast and within 2 minutes the temp of the drive dropped from 110F to 90F. Afterwards I turned it back to Auto. No alerts since but I haven't put a major load on the system beyond copying files. (We'll see what happens on the first scrub.)Overall I'm happy. I have 90TB RAID6 on this storage. The performance is solid. Definitely would recommend.
