QNAP 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.

Reviewing QNAP TR-002 for Linux/Ubuntu (Kubuntu) Setup: Installed two 4TB drives, preset mode to raid1, followed instructions, and two beeps after Set button, it was ready for setup. Ran partitionmanager, formatted it as ext4, with mount-point /backup, which took only a few minutes Test: Copied a few hundred MB files. Removed first harddrive, copy/pasted some more files, read/write was fine with only one drive in bay. Re-inserted the drive (after a few minutes (recommended)), and raid started rebuilding. That took several hours, was completed sometime overnight. Issues: Unmounts randomly after some time, even though computer is not suspended/sleeping. Fix: google GRUB_CMDLINE_LINUX_DEFAULT usbcore.autosuspend=-1 Nice to have: Would be nice to have some basic software for Linux, which provides status information, such as raid rebuild time.

Dead on arrival. I originally bought the 4-bay TR-004, and it arrived completely dead. I returned it and ordered the 2-bay TR-002, only to experience the exact same failure right out of the box. The enclosure simply refuses to establish a USB connection. The USB light stays completely unlit, and it is not recognized by any computer. I extensively tested this across 4 different machines, including my HP EliteDesk, 2 laptops, and a Mac, using multiple cables. The computers never even register a handshake. To make sure I was not crazy, I pulled my hard drives out and plugged them into a basic Sabrent docking station, and they work perfectly fine. I even tried a hardware master reset on the QNAP unit, but the internal controller would not even boot up to register the command. Running into the exact same hardware lockout across two completely different models points to a serious quality control issue. Save yourself the time and look at a different brand, because I am sending this straight back for a refund.
