Oyen Digital Novus 20TB External USB-C Rugged Desktop Hard Drive

I have about 15 TB on mine now - Photos and videos for my YT channels .Picking up another one. This has about 400 hours of run time on it and no problems at all. Going on 4 years now. It is not powered on all the time. I do a back up 3 times a week and other wise it is off.It's power supply plugged is into my systems APC so it gets clean power all the time.

First off, the product seems robust and well equipped with cables and instructions. It seems to work well.However, it's made for the US market and ships only with an American two-pin adaptor. I can't find anything in the sales blurb that states this and Amazon does not seem to want me to contact the seller directly.I just don't understand why Amazon.sg sells products that weren't designed for the Singaporean market. I now have to go to a third party to enquire about replacement adaptors.Moreover, most adaptors nowadays come with a range of international fittings. Who still ships single market adaptors? 95% of us don't live in the US. Definitely time to broaden a few horizons.

I've used a variety of external drive enclosures over the years, mostly just for USB drives attached to a computer. I bought the Novus because the drive I installed in it will have to go on the road with me from time to time and I wanted the protection afforded by the silicon "sleeve". It's electronics and a drive so I will treat it accordingly. The protection is for the occasional bump it may get.First, it arrived precisely as predicted, well done Amazon.Packaging was easy to open and everything was individually wrapped. There are actually PRINTED instructions included, although they're hardly necessary. This is a very simple, but well designed enclosure. And everything fits like a well engineered and constructed product. As nearly as I can tell it is manufactured in the USA using materials from the USA. But I could not find that specifically stated even on their web site.My 8TB (purchased separately) 3.5" drive slid right in - at a slight angle to enable aligning and mating the SATA connector in the case. This was very easy. Everything fit, aligned and went together perfectly. There was a small zip lock bag containing 12 screws - 8 for mounting the drive - only 4 required. Two different types provided. And there were four black screws to secure the "sled" inside the case. It is also very nice they included a small MAGNETIZED screwdriver. This is good because they ensure users have the right SIZE and tip screwdriver and also because the tiny screws are...tiny. MUCH easier to install using the magnetized screwdriver than trying to start them by hand.I may not get out enough but I haven't seen a lot of thunderbolt connectors, although I would like to. And I don't have any. So it is great that they also provided a USB-c - to - USB-A cable for connection to my system.The one 'ding' I'll give them is the freakin' wall wart! I would very much have preferred a slightly larger enclosure with the wall wart electronics inside the case and a normal AC power cord. I thought about taking off a star in the rating for that but they're not the only ones guilty of using them! So suffice to say, it's an area that NEEDS improvement.Overall, an excellent and very well designed and manufactured product. I would buy another if I needed another external enclosure and highly recommend them to anyone who may need one.

I have tried everything to have it appear on Disk Utility or Finder, but it does not appear.My system : Mac Book Pro with Big Sur

The enclosure works well for what it is, but it powers down and goes to sleep when left alone, but does not wake back up with the computer. I have to power cycle the enclosure to reconnect the hard drive. It is very annoying as I was looking for something that I could leave and forget.
