TR-002-A-US 2 Bay USB Type-C Direct Attached Storage (DAS) with Hardware RAID (Diskless)

Muito bom, fácil configuração, atendeu expectativas.

This enclosure worked for WD16tb drives in raid 1 array. Easy to setup, flip dip switches to raid 1, insert drives power up format for OS. tested removing a single drive putting in a toaster and it was read just fine with all data there. Erased drive and reinserted in enclosure it automatically started rebuilding array. The only negative I have is when the array is degraded the enclosure beeps very loudly 3 times every 5 minutes, there is no control to shut it off or silence it. Even tho their raid software is not necessary I highly recommend installing it for more visibility (for instance will give you % complete while rebuilding array). It also allows you to upgrade firmware on the enclosure, read logs, etc... The enclosure also has hardware raid support chips onboard so it offloads some of the work from the CPU. I previously used a major mfg pre-built raid DAS units, but this is better because the disks can be read directly without enclosure encrypting disks limiting them to only being used in that specific enclosure. it was also cheaper to buy disks and this enclosure than their pre-built models. 👍

Setup in software RAID1 and has been performing fine with a pair of 6TB WD Red Pro HDD's. Getting this set up on my M4 Mac Mini took some effort, but with the help of Google Assistant we eventually got things up and running and also downloading and getting the QNAP App onto the MacOS was again challenging due to Mac security settings not openly allowing the app to be downloaded and installed but we go there in the end.

I've now tried the TR-002 and TR-004. They are much different in their performance: **TR-002 Review** I did some initial speed trials using two identical Seagate EXOS drives in RAID 0 (striped) mode. I used Amorphous Disk Mark on a Mac to measure speeds. The cable that came with the enclosure gave different results depending on which orientation I inserted the USB-C side of the cable into the enclosure. Read speeds were the same for both orientations (~350 MB/sec), but write speeds were 20 MB/s in one orientation and 300 MB/s in the other. This same cable gave 500+ MB/s read and write speeds in either orientation when attached to a Samsung T5 SSD. I got similar results for a few other cables, and finally came across a cable in my inventory that gave consistent high read and write speeds in either orientation on the USB-C side of the cable. There was nothing special about that cable. Bottom line is that as other people have said, this enclosure is very finicky about which USB cable is used. Cable issues aside, its a gets-the-job-done kind of enclosure. Its mostly plastic, but seems solid. Its a tool-free enclosure. QNAP has Mac, PC, and mobile apps to manage the enclosure, including the ability to update the enclosure firmware. I give the TR-004 4.5 stars. **TR-004** This thing is advertised as USB-C 3.2 gen 2 with 10 gbps speeds, but it does not operate at this speed. It only operates at 5 gbps = 625 MB/s. This seems ok, but then the next issue is that the controller is only SATA II which operates at max 3 gbps = 375 MB/s. Still not horrible. However, in practice, it doesn't do better than 250 MB/s no matter what drive configuration. A single drive does the best at 250 MB/s R/W. Everything else is slower. RAID0 with 2 drives gives a few MB/s slower, and RAID0 with 4 drives tops out at 225 MB/s. So amazingly 4-drive RAID0 is obviously slower than a single drive configuration. What's worse is that the TR-004 in RAID10 with 4 drives is super slow - only 110 MB/S R/W for large files. In comparison, my TR-002 with the same brand/model/size drives does 400 MB/s R/W for large files in RAID0. What a disappointment for the TR-004. I don't understand how QNAP flubs something like this. Sending it back for a refund. I give the TR-004 1 star.

I have bought several QNAP devices, and each one I love. QNAP is just reliable, I have never had issues with anything they have made. The 2-bay drive is super easy to set up. Just download the software, plug it in, and it automatically recognizes it. There are sometimes it doesn't; if that is the case, you might need to go into disk management and format the drives. This is a great DAS for anyone who just needs a little extra drive space for their computer but doesn't want to go through the hassle of setting up a NAS.
