MiniPro RAID V4 USB-C (10Gbps) Dual Bay Enclosure

Version 4 of the Oyen Digital SSD MiniPro RAID is a significant upgrade from Version 3. Specifically, the following:1. The V4 is encased in a silicone bumper. The unit is quite rugged, and the chance that the added protection of a bumper will ever be needed is certain to be miniscule. However, for the user who experiences that one-in-a-million catastrophe where the bumper saves the day, it will at that moment be worth substantially more than the cost of a new unit. It never hurts to have added protection.2. The on/off switch on the V4 is recessed within the bumper. The one flaw in the design of the V3 was that the switch could easily be turned off while in use by accidental contact with anything. The addition of the bumper fixes that problem.3. The V4 adds the ability to daisy-chain additional USB devices. Let’s face it - one of the biggest advantages of the USB environment is the promise of being able to daisy chain other devices onto whatever you plug into your computer. Very few manufacturers enable you to benefit from that feature. Note that Oyen Digital cautions that you should use DC power (and not bus power) if plugging other devices into the V4. Take this warning seriously. On DC power, I could operate multiple daisy chained SSD’s, Blu-Ray/DVD/CD drives, and a mouse. On bus power, my computer would recognize other devices, but could not operate any except the mouse, and then only if nothing else was plugged in.4. The price of the V4 is $100 cheaper than the price of the V3. Until they put it on sale at clearance prices, forget the older model. The V4 has only added features and a cheaper price.I note that when I first got the unit, I plugged it into a (very expensive) Lenovo laptop’s Thunderbolt port. It worked fine on DC power, but would not power up on bus power. (Once on, I could switch from DC to bus power, and it would continue to work.) I tried several other laptop and desktop computers, and the Raid V4 powered up flawlessly in each when using bus power. Turns out that this was exclusively a Lenovo problem. Seems that they and some other manufacturers under-power certain of their ports on select computers. Although neither of the Thunderbolt ports on that laptop could power up this device, the same laptop also has a separate USB C port that can. (I’ve been told that I could also use a splitter cable to simultaneously draw power from 2 USB A ports, but I haven’t yet tried that solution.) Using that USB C port, the Raid V4 works flawlessly on bus power, so long as I don’t daisy chain other devices. (As above, if I use external power, I can daisy chain all I'd ever want.)I need a lot of storage (currently a minimum of 20tb) for work I perform on my laptop. Manufacturers long ago stopped providing room inside their laptops for additional drives. I attached the Raid V4 to my laptop with nano tape next to a couple of 8tb U32 Shadow SSD’s, giving my laptop 36tb of storage, which should keep me going for a few more years. I couldn’t be happier with this purchase.

I have become a oyen digital fan since buying my portable 4tb ssd a few years ago. This is also excellent. Spread the word and buy quality!

I bought external HD enclosures 20 years ago with same switches, plugs and enclosure parts. This item feels cheap and may the chipset be uptodate everything else physically involved is cheapest china made. The charger, cables at least 30 years old stuff. Too bulky. Don't buy!

Super easy to setup and add the SSDs functioning 4tb RAID for photos

I'm partial. Used the v1, v2 and v3 versions. They just work and are very cost effective.

I'm very happy with this product, it's all that I was looking for, simple and small, easy to install and use, good materials, I recommend it.

I purchased two SAMSUNG 870 QVO SATA III SSD 8TB 2.5" SSD drives, installed them inside this enclosure, and set the device at RAID 0 for performance. I have been using it as my primary media drive to store images from my Sony A7RV, which produces pretty big JPEG (40-80 MB) and RAW files in the range of 150 MB each. It is super quiet and does not heat up much.After using it for a month or so, I have nothing negative to say about this drive. I use offsite backup services, so I didn't need the safety of RAID 1-5 for this device. However, I am considering getting another enclosure and setting up a second one with RAID to rsync from one to another as a local backup in the near future.

Takes up much less space on my desk...works as advertised
