Woah this thing is fast! Tested on my MBP M2 Max and a Mac Studio M1 using 5GB (large file) setting using blackmagic's testing tool (avail. on the app store). The picture is the MBP but about same results for the Studio (though note that you have to use the ports at the back; the ones at the front only allow transfer up to a little over 300Mbps) Cable is provided (that's important). The drive comes formatted as HFS+. First screenshot is with the original HFS+ partition, second is after re-formating as APFS. HFS is for compatibility with older MacOS pre-Sierra and is less optimal for SSDs, especially for smaller files. Also while APFS is not PC-compatible, neither is HFS so there is little to gain for keeping it as HFS for the regular Mac user. Other big plus: the drive is small (basically the part not covered by the rubber thing in the middle is slightly smaller than a credit card in surface, so the whole thing is just a nudge wider than a credit card) and relatively thin. Fits in a jeans pocket like a pretty full wallet would (not that I would carry it like that, but it means it fits easily in a front pocket of a backpack) NOTE: External SSDs have a bad tendency of failing (just bought this after my Kingston failed within 6mo - granted manufacturer warranty is good for 3 years for these type of devices) so will come back in ~6mo to confirm everything is fine.

Here are performance tests of (a) this product, (b) mac mini m4 internal hard drive, (c) external 2.5" mechanical hard drive from a few years ago via USB-C. As you can see this external NVME drive is faster than even the internal drive, and 50x faster than a mechanical drive. I bought this specifically to use with the base Mac Mini m4 with its very small internal storage. Initially I tried a mechanical drive to see if I could manage. But it was absymally slow trying to manage my photo library on it. And I bought the Mac because I wanted to use its AI to catalog the people in my photos. I did not find a user friendly, accurate Windows software for this to use on my gaming PC. So decided to buy a mac.

This is (at least) my fourth Oyen Digital drive. They are blazingly fast and don’t get hot. I’ve used others (and still have them), but each has had issues or doesn’t make 8TB. The Sabrent, which are more compact, run extremely hot (so hot they are hard to touch). I love the mini Sandisks, but one failed on me early on. I’ve since read other warnings on those. (All drives will fail at some point, but that one was not old - and I was able to reformat it, so I don’t rely on it.) In all, the Oyen Digital drives have proven to be reliable in the long run, fast, and reasonably small and durable. And they don’t get hot (just warm, as you’d expect).

Just got it a week ago. So far seems solid, one of the best investments for heavy video editing on the go. May be another larger 1TB.

I must add on for anyone with a Mac with very little storage. Highly recommended.

Extremely fast, great for quick backups and transfers. Make sure you have an appropriate thunderbolt cable though!

I bought two of them, much cheaper than apple internal storage but still very pricey considering you can buy two 4TB ssd drives for under $600 but this is what you buy if you need all your files together in one drive and need them to run real fast. The only down side I've experienced is that these drive become noticeably slower the more they fill up which is good to know if you are using these drives for video editing

I have the 2tb version and it's connected to the thunderbolt port of a mac mini M4 pro. Photo of the speed test attached, because I would not have believe it. Insane. This thing is ridiculously fast. Definitely pro level on a budget and most certainly worth the money. Yes, a T7 will give you amazing everyday speeds and yes, it's ALL dependent on the connection and the OS speed, but if you want blazing, future proof speed, this is it.
