At times, plugging it directly into a Thunderbolt 4 port on an M2 Mac mini with the provided cable, it connected using USB 3.1 rather than Thunderbolt. I verified this by looking at the USB and Thunderbolt buses using System Report; also BlackMagic disk speed tests were much slower when this happened (700-800MB/s rather than 2400ish). I'm not sure if that flakiness is caused by the drive, the Mac mini, or the cable—but I'd guess it's the cable. Other times, it connected to the Thunderbolt bus as expected.
Mostly I will have this connected to a Thunderbolt 4 hub that nets me two more Thunderbolt 4 ports. I've found that this setup, with otherwise base M2 but upgraded to 24GB RAM, plus the external TB4 ports and storage, is very cost effective for my needs. Note that there is no decrease in speeds having it connected to the hub vs. directly to the Mac.
Update 1: Because this SSD (the 4TB version) is **both 50% faster and 15 times larger** than the internal SSD on my 256GB M2 Mac Mini, I have turned it into a bootable drive and am running macOS from it. No complaints! Upgrading the Mac Mini at time of purchase to 2TB (half the space!) internally would have cost a whopping $800 extra with Apple's pricing, and I'd have less space. Not to mention it's impossible to upgrade the internal storage after the fact. Setting up as a bootable drive was simple and painless for me. More benefits of the big, fast bootable drive include plenty of space for memory swapping at higher speeds than the internal SSD if I run out of RAM, plus being able to keep large cloud storage drives fully available offline (Apple's FileProvider forces many of them to live in a particular location on the same volume macOS is installed on, which was too small for them until I moved to this drive).
Update 2: If you're looking for a Thunderbolt drive that's a lot faster than this, don't bother looking. Theoretical max data transfer speeds over Thunderbolt 3/4 are limited to something like 22 Gbps (maybe 24 Gbps for Thunderbolt 4?) which translates to 2750MB/sec for Thunderbolt 3. The rest of the 40 Gbps bandwidth of Thunderbolt is reserved for other things. With this drive, I've gotten around 2480MB/sec read and 2400MB/sec write in BlackMagic disk speed benchmarks, which is close enough to top speed that I've stopped looking at, say, external Thunderbolt SSD enclosures + NVMe SSD sticks to try to get faster speeds than this.
Even running VMs, the device takes hours to heat up, and it has yet to get uncomfortably hot. Just warm. I see no performance difference when running a VM off this external SSD. That’s wild.
I’m very happy with this device. It checks all of the boxes. It’s fast, it’s durable, it’s cool, and it has plenty of space.
2800 MB/S read and 2550 MB/S write when tested in Mac with Blackmagic.
When I bought, the 1TB unit seemed like the best price point, with the 2TB being 2.5 times the price for double the storage and the 4TB unit being 5 times the price for four times the storage.
The drive itself is compact and silent. It comes with a relatively short (nine-inch) cable that gets the job done but doesn't seem to be anything special. In operation, the drive doesn't seem to get as hot as some others I've seen, although it does get somewhat warm to the touch when plugged in for a while.
I have mine connected via Thunderbolt 4 to my MacMini and it works without issue. SanDisk provides very minimal instructions, but thankfully it really is as simple as plugging the cable in and letting Mac OS do its thing.
According to the Black Magic Speed Test, I'm getting 2785 MB/sec read performance and 2580 MB/sec write performance - this is quite fast for an external drive. For comparison, the built-in NVMe drive in my MacMini benchmarks at about 3000 MB/sec read performance. A higher-end OWC external RAID 0 device running 8 2TB high-end NVME drives actually returns about 20% lower benchmark scores than this SanDisk, despite it costing much more per TB than this external drive.
Overall, I'm impressed with this drive enough to use it for some critical files and I've had no issues with it so far. There've been no compatibility issues and it seems to run just as fast as the internal disk no matter how I use it. If you're looking for a good quality and speedy external drive, then I have no trouble recommending this little SanDisk - definitely seems to be a gem, especially when you consider the price.
I use it for Lightroom editing have have zero complaints. Ran me $387 (listed as 52% off at the time) in Feb 2024 - which is far cheaper than I could built it.
It gets warm to the touch, has an indicator led, is ruggedized, and has worked in every port and dock I've tried it in flawlessly. No idea on longitivtiy at this point, but damn it is fast and at a good price point.
Considering grabbing a few more.

Eine Rezension gibts bal auf da-schau-her.de
Using it on a Mac Mini and it is nearly as fast as the inbuilt storage. Makes editing videos and photos super quick.
The design is very sleek and it is small and very portable. It stays cooler than expected. The included cable is quite short but does the job.
It is really expensive and only provides the top speeds with thunderbolt. If you have only usb 3.2 or don’t need the fastest available then there are much cheaper options available.
