MAIWO Dual Bay Raid Enclosure for 3.5” SATA HDD, 10Gbps SATA Docking Station with Adajustable Fan, 4 Raid Modes,Type C SATA Enclosure for 44TB Capacity Expansion

The chassis is made of metal, and has a nice feel. Strong and sturdy. The installation of the matching HDD's was pretty straight forward. The only drawbacks are not actual operational paperwork and the speed of the array after configuration as RAID1 is really slow. I placed 2 8tb how's in RAID 1 configuration and plugged the box into a USB 3.2 pirt. Average write speed from an NVME M.2 PCI4.0 SDD was only 20 mps. When using the 8tb drives directly connected to the 3.2 USB port ithout the RAID enclosure averaged a speed of 220mps. So for backups, it's going to be slow (time wise) if you have a lot of files.

works good

Por el momento todo bien, llevo algunos días utilizándolo con un disco de 3.5 de 1 Tb y otro de 2.5 de 500Gb que no usaba y ya por fin los puedo utilizar. No está configurada con RAID, ya que me interesa poner información diferente en cada uno y por lo pronto todo bien. Buen diseño y la carcasa es toda metálica. El switch superior trasero regula el ventilador ya que no es automático y no se detiene, tiene dos modos para regularlo. El dispositivo se apaga solo cuando deja de recibir información de la PC pero el ventilador lo tienes que apagar manualmente. La tengo conectada con USB a una PC con Windows. En cuanto a velocidad de transferencia, con la configuración NORMAL, le estoy transfiriendo 100 Gb de archivos variados de la PC al disco 3.5 y ronda entre máximo los 41mb/s, no me quejo.

Bought this to back up my Synology using Hyper Backup using it in JBOD mode. After running the backup job for a period of time, the Synology would report that the disk was ejected improperly and the backup failed. This happened on multiple occasions, so I took the disks out of JBOD mode and ran the drives independently, manually splitting the backup between the two drives. Got the same error. I read an article on Reddit about similar issues that were evidently caused by the different chipsets between the NAS and the drive. Using a USB hub was the solution, so I bought the same one mentioned in the article that resolved the problem, but I got the same error, and after that attempt, the NAS wouldn't even attempt to mount the drives, with or without the hub. I moved it to my Windows system and tried reformatting the disks to NTFS, but I received "fatal hardware error" messages until Disk Manager would no longer respond. I couldn't even access the disks through DISKPART. I swapped out the drives with another one, and it still wouldn't function properly. I ended up returning the unit, as I could no longer trust it for backups on any platform.

Not an attractive design, but works like a charm. Makes a great external backup.
