OWC ministack for MacMini

By Ronald

I purchased the 2TB version which is more than sufficient for my 500GB MacMini. The only thing I will criticize is that the setup instructions come with the Acronis Cyber Protect Home Office built in. If you have a Mac, you don't need this; Apple's Time Machine provides excellent backup, and it comes with your operating system. After going through the OWC setup instructions, you'll find that Acronis is being offered for a free 1 year subscription. To setup your OWC miniStack, just go straight to the Time Machine setup.

Nice match for my M1 Mac Mini

There was a wonderful setup program that ran automatically, when I first connected my miniStack to my computer, that helped me partition and set up the drive. So far, I haven't had any problems. The connection is steady and everything works well and as expected. Thanks!

Incredibly durable and reliable.

We have used several large format drives in the past, and this is by far the most stable and reliable one we've had yet. The size is great - does not take up much space on the desk top (about the size of a Mac Mini). We've had no issues with failures or transfer speeds. Heartily recommend this drive.

First impressions: wowza.

Aesthetically, this drive looks identical to my Mac Mini. The unit looks super sleek when stacked under my drive. I had the 8TB custom built for back-up purposes primarily and it seems extremely responsive with TimeMachine scheduled back-ups. The drive isn't what I would call silent, you definitely hear this drive if you're at the workstation while it's writing but it's not distracting at all. Set-up and formatting was incredibly easy. The auto formatting software comes on the drive. Plug it in, go through the set-up prompts (pick either IOS or PC) and you're good to go. Good device. Hope it lasts since I've never paid this much for an ED ever.

Almost perfect, so far

With the reviews coming out for the latest G-tech drives, I started looking for an alternative. One month in and multiple transfers on the two 12 TB drives, they are almost as quiet as most of my g-techs. No glitches, so far. The power light on one of the drives does not light up.

Great

I already have an 8tb mini stack. Can two mini stacks be connected and work together. Or, would they need to run independently?
Asked by: Joseph E.
In theory you can use SoftRAID to create a RAID 0 or RAID 1 volume, but you will take performance hits since they are not in a single enclosure.

question

I see a DC power port, can these drives be bus powered through the USB3 connection?

Sorry, no. They require much more power than what a USB 3.0 port can provide.
