40Gbps M.2 NVMe SSD Enclosure, Maintenance-Free, Dual-Sided Raised Heatsink, Tool-Free Quick-Open, for Thunderbolt 4/3/USB4/3.2/3.0, for Mac Mini M4/Pro, M1 M2 Pro/Max, SSD Size 2280/2260/2242/2230

Most of these cases are pretty low quality. I bought a bunch with the thought of keeping the best and returning the others. And this one won by a a lot. It's much more substantial that the others, without being bulky, plenty of heat sinking capability. The materials and workmanship is on point. And even the led light is high quality and placed well. Not like some of the others with their little point lights or little holes to see the led through. The USB cable is also thicker than the others, and this played a role in what speeds each one supported. While some of the others also had high speeds, this one was more consistent across all my testing, and compatibility.I used a MacBook Air M1 and a Dell Precision 5520. The MacBook had no issues with any of them, just small speed differences. The Dell though, man what are they doing, some of them didn't even mount! Compatibility was a nightmare. And sometimes they'd connect and then disconnect a short while later. This one was the most reliable with that pesky Dell. (I put most of the blame with Dell, and some on Microsoft)The speeds will depend on 1) Your SSD and 2) the negotiated connection speed. I was testing with a Crucial P1 Plus, so SSD speed was NOT the limiting factor. lol. If you can connect with thunderbolt speeds, you're getting 2-3gigs/second, less with USB3, and much much less with USB2.BUT, you may want to connect with USB3 if you'll leave this plugged in long term (or any thunderbolt device for that matter). As when you're running thunderbolt, not only will the device get hot to the touch (but not burning, these things can operate at pretty elevated temperatures), but so will the controller on the laptop! And that's with no transfers even. This was worse for the Dell than the Macbook, but both heated up. Not great for long term use plugged in. Since it takes like 30 min to heat up, it's not even noticeable if you're just transferring files real quick. And this thing is REAL quick at 3 gigs/second. lolThe heating was only warm to touch with USB 3 negotiated connections. This is not a flaw with this device, as all the devices I tested had the same pattern. So for long term plugged in, use USB 3. Still pretty fast, but much cooler temps.Also, even the packaging was high quality. Probably overkill, but nice touch.

I have multiple Samsung 990 EVO Plus's connected to a current ASUS laptop with TB4 ports and running PCIe Gen 4 motherboard along with all TB4 cables from OWC and Cal Digtl cables.- PERFORMANCE - The NewQ enclosure gives me performance that exceeds their own claims!! NewQ claims up to 3000MB/s - I got 3150 on reads, 2520 on Writes and 3280 on Mix. I use CrystalDisk Mark 8.06 for performance measurements.- Tech Support - I did have some problems getting it to work properly and contacted Support. They responded the next day. While it took a series of email exchanges to resolve the issue, including a firmware update, the issue has been resolved, and now my performance is rock solid. Their tech support was truly there for me. I will add that I tried the ACASIS enclosure which had performance problems (like under 1000MB/s) and emailed their tech support multiple times - THEY DID NOT RESPOND. Like wise I contacted ORICO tech support and they also did not respond. So NewQ's tech support wins hands down.- Quality - from the packaging to the actual enclosure itself the quality is evident. Nothing flimsy or cheap whatsoever._ Takeaway - Great product and the price is RIGHT.

Nice speeds using a Samsung 990 Pro 2gb nvme! Unfortunately, #$@!% Windows disables write caching by default on every USB hub I've used. Once enabled, you get the correct write speeds. Otherwise, you're capped around 500 mb/s. So far, temps have been great as well. Was looking for a newer enclosure with the ASM2464PD chip instead of the JHL7440. So was deciding between this and the Zike. What sold me was the easy to see led! Plus I liked the design and the orange cover is a nice bonus!

I bought it to use on USB4 and the read speed is fine 3630 Mbs but the write speed is only 660 Mbs. On USB3.2 write speed is 997 but on USB 3.2gen 2 by 2 write speed is 2025 Mbps. There is no way USB 4 should be slower. By the way this is with Crucial P3 pcie 4.0 2TB drives. I bought 6 of these enclosures and they all tested the same. Also the included thermal pad is too thin to contact both the drive and the enclosure, making it useless.

This is well made. It is FAST and detects usb2,3 and 4 connections along with thunderbolt. I purchased it because occasionally I need to swap drives and wanted a case that will work with usb and thunderbolt/USB4. This one does. The performance of the case is flawless. The heavy case dissipates heat well. Every time I change the drive i have to pop out the little grummet and over time I don't know how this will hold up. It comes with a bright orange condom which is great because if you drop it, something could break and the orange makes it easy to find but it can be a pain to get on and off. This is the heaviest case I have ever seen which is good and bad. Great for heat dispersion but not very portable Overall a good enclosure for the $.

This is a great enclosure, especially if you want to upgrade the storage for cheap on one of those new M4 Mac Minis. Read a many other enclosure felt quite hot to touch, but this one had very few complaint on that front.It only gets a little warm, despite being attached to the computer all day. Definitely worth recommending. Even the packing feels quite premium

Admittedly, I am not moving tons of data. I do casual video editing at 4K resolution, and backup a lot of small media assets. This thing FLIIES! I'm able to keep sustained read and write speeds above 3,000MB/s with a Samsung 990 Evo Plus. It does get warm, but never too uncomfortable to touch. Despite being tool-free, it feels very sturdy and well built.Almost forgot, the included cable is very high quality too!
