Review on 💾 Terramaster D5-300C USB 3.1 (Gen 1) Type C 5-Bay RAID Enclosure - RAID 0/1/Single Support, Exclusive 2+3 RAID Mode, Diskless Hard Drive RAID Storage by Daniel Aboubakar

I have been using a Dell R610 as a file server for a long time and wanted something low power, quieter, cheaper etc. I got this one 5 bay Saw the unit and with its unique RAID configuration I thought it would be perfect as I only need redundancy for some of my data.It comes with a screwdriver to mount the drive, extra rubber feet and labels.I was glad to find it at the extras but that's where the luck stops, despite the fact that the block itself is metal, the plastic front and back are a problem because any operation of a platter on hard drives reaches a resonant frequency from plastic slots and makes enough noise that I it through the whole office listening instructions and installed two new WD Red 8TB drives in slots 1 and 2 after RA ID-1 had been set up and the device reset (again per instructions). The hard drive was not recognized by the operating system. I had to restart the device for it to be recognized. Then I added a couple of matching drives in bays 3 and 4 to use as a zpool and a 10TB drive in bay 5 as a spare. I use this for storage as that is its purpose and the first thing I did was sync a few TB into a RAID 1 array in bays 1 and 2. As far as I can tell, writing data to this drive went smoothly. Both activity lights showed writing to both drives and I was able to confirm this later. I then created a ZFS zpool from disks 3 and 4 (e.g. software RAID) and synced the files from the RAID 1 array to those disks. I immediately noticed that the performance is half the advertised speed and started looking for the reason. Then I saw that the disk 2 lights only blink when a directory is scanned. All reads from the RAID array are isolated on disk 1. So you have disk 1 which is fully utilized and disk 2 is idle. RAID-1 has two goals: provide redundancy in the event of drive failure and double read performance. This product offers no performance increase over a single drive (max. 172 MB/s equivalent to a single drive). Worst of all, this product shifts all read wear to disk 1, giving you a far shorter disk lifespan. failed. Then the RAID 1 array appears, allowing slow access, and then disappears. I had to hard reset the device to keep the RAID 1 array visible. All of this indicates that I have had this product for a few days now. That's a great idea and if it works I'd be very happy. I was hoping to save some money since Synologies are very expensive, but I can't afford to lose my family's photos and videos. So if you can't trust your RAID 1 backup, there's no point in having one. My advice: Stay away from this product and this company if your data is important to you. And if you don't value your data, why buy it at all?
