The enclosure was fine, the accessories were bad or missing. After a long email correspondence with Acacias Customer Support, which included pictures of what I received, they told me that the cable I got was not their cable and so I thought I might have received a device that had been shipped to someone else and returned without the heat pad and with a useless usb cable, and I ordered a replacement. The Acacias product package was not sealed so it was not possible to tell if it already had been opened. The replacement just came in and when I opened the package (it was also not sealed) it contained a proper Thunderbolt 4 cable and the heat pad, and when I tested it I received the kind of speeds I expected - about 2800 MB/s using the WD 1 TB 2280 memory. That makes it clear that I received the bad usb cable due to my original order having been returned to desertcart by another customer and not due to the fault of the vendor, so I have revised my review. This enclosure works very well, although it does get very warm and probably needs a cooling fan as well as the included heat pads. The speeds are everything I expected and the included Thunderbolt cable works properly. It is a bit short for me, but it is the length specified in the product description. I am happy with the replacement and feel capable of recommending it. If you want external drive speeds close to the speed of your computer memory consider this enclosure. --------------- I recently bought the version of this enclosure that contains a fan for cooling and when I tried to leave a review desertcart told me that I had already reviewed it, although that version was the version without the fan, so I am adding this review to the end of the original review. While the original enclosure is a great way of adding high speed memory to your system it suffered from one drawback and that is it needs cooling. I solved the problem by buying a small muffin fan and attaching it to the enclosure and, with that, it ran cool and I had no heat issues. This new enclosure solves that problem and I have replaced the version without the fan with this one. This is a first class enclosure with transfer speeds as high, if not higher, than the internal memory of my Mac M2 Mini. Repeated use of the Black Magic speed app showed no slowdowns due to thermal throttling so it is dependable and fast, even after long use. Thee are some minor issues. First, the manual that comes with the enclosure is the manual for the version without the fan so it contains no information about the cooling fan. There is a small button on the side of the enclosure to turn the fan on and off, but even when holding the unit next to my face I could not feel air moving. To be sure that the fan was working I had to hold it next to my ear, and I could hear it running. There is also a small LED on the side of the enclosure and it shows a constant light when the fan is running and a blinking light when the fan is not running. I have picked up the enclosure during the day and found it to be slightly warm while the old enclosure was hot to the touch without the muffin fan I attached. This is a great enclosure and I believe that it deserves the 5 stars I have given it. Review: Reliable, fast, solid construction, easy to re/use with no tools, stays fairly warm - This enclosure seems reliable, fast, easy to use, and is recommended (though a major caveat is I’m a first-time user of SSD enclosures and in the first month of use.) FEATURES The enclosure is aluminum and seems solid. The no-tool installation was super fast and easy. ACASIS includes plastic spacers so SSD sizes shorter than 2280 are supported, plus there are couple thickness of thermal stickers ready to apply that help dissipate heat between drive and enclosure. The installation could not have been easier, plus it’s easy to pop open if needed. The kit also comes with a USB4 compatible wire that’s less than 12” long. That’s short but I’ve read this length is best for highest transfer speeds in USB4 so doesn’t seem a shortcoming of ACASIS. BASIC SETUP So far it’s been fast and reliable. My setup is 3-partitions on a 4TB drive connected to Thunderbolt/USB4 MacBook for Time Machine backups in one partition, SuperDuper! app weekly backups in another partition, and manual archive in a third. SPEEDY All seems fast, reliable, and compatible with USB flavors from 2.0-4. My SSD supports 3500MB/s transfer with actual rates in practice at around 2750. This is apparently expected performance via Thunderbolt/USB4. Regardless, it’s a helluva lot faster than my old USB3 SSD and platter setups with speeds of just 50-70! WARM The enclosure does stay fairly warm, with added heat during backups. It’s not uncomfortably hot as I can easily tough the enclosure, but it is significant. I don’t have experience here so I can’t say if too hot or fine. Hopefully this won’t bite me later. TO FAN OR NOT TO FAN I was close to choosing an enclosure with a fan because I read lots of reviews about heat issues. I chose against it because there are even more complaints about whining noise and broken fans over time. I figured the fan would be tiny and prone to breaking with replacements hard to find. Then, I’d end up with an enclosure without a fan anyway. I’ll have to see if the heat is a problem over time. SATISFIED All told, this setup seems solid, fast, easy to re/use, and is recommended. Biggest issue maybe heat though it may not because it’s actually normal temp. ## Features - 【No Noise SSD Enclosure 】2026 Upgraded NVMe ssd enclosure adopts aerospace-grade aluminum alloy material and is used with a silicone thermal pad with high thermal conductivity, ensuring your M.2 NVMe SSD maintains peak performance and stability during heavy workloads and Ensures quiet operation without fan noise - 【New-generation Intelligent Chip----JHL7440 】 Thunderbolt 4 & M.2 ssd enclosure​Featuring the Intel-certified JHL7440 chip, This external hard drive ensures dual-chip reliability and stability.

(with "E") the box states the included cable is Thunderbolt 3. it drops the false claim printed on the earlier TBU401 box of "USB 4.0". -----( newer TBU401E )----- https://m.media-amazon.com/images/I/41n8r+Qr+4L.jpg https://m.media-amazon.com/images/I/41vqV5YTrjL.jpg https://m.media-amazon.com/images/I/61iyaANm7qL.jpg https://m.media-amazon.com/images/I/61TKeFrG5NL.jpg -----( original TBU401 )----- https://m.media-amazon.com/images/I/81-0pILAsAL.jpg it seems like all brand enclosures boasting "40Gbps Thunderbolt4 / USB4" are JHL7440 chipset based. the JHL7440 is actually Thunderbolt3, (not TB4 or USB4), which actually produces only 22Gbps data transfer. (per Intel, 18Gbps of 40Gbps is reserved for Displayport video). they also do not support USB Gen 2x2 20Gbps mandatory with USB4. only USB 3.1 10Gbps. there's no telling which exact model ACASIS (or anybody else) is shipping at this very moment. none can possibly transfer 40Gbps - that's 5000 MB/s. they all get approx half that. none are USB4 - their USB interface is only USB 3.1. that's all there is to it. the ads are all consistently deceptive and untruthful. and most Answerers in the Q&A only help compound the fraud. . **Q: Does this enclosure support nvme 4.0 or only 3.0? will using a 4.0 capable drive provide speed improvements with this enclosure?** A: No, you most likely will see no difference as others answered partially but not directly. You are bottlenecked by 1- Thunderbolt 3, which theoretically can handle 40Gbs/5,000MBps, but in the real world in my experience tops at 3,500~ish. 2- Various other parameters such as cable quality, NVME drive technologies, SLC, TLC, QLC, VNAND, etc. My suggestion: Buy the BEST NVME 3.0 you can, with the largest DRAM or SLC cache, AND make sure that below that cache it has VNAND instead of regular NAND. Keep an eye on too high densities as well. SLC is faster than TLC which is faster than QLC… Best. R. **Q: Hi, does this drive run a 10gb if i hook it up to a regular usb 3.2 gen 2 port? thanks!** A: USB 3.2 Gen 2 max speed is 10 Gbps. The USB port cannot get faster speed, just because a faster devices was connected to that port. **Q: What is the difference between tbu401 and tbu401e?** A: review photos show the models are marked differently on their aluminum bodies.

Biggest issue maybe heat though it may not because it’s actually normal temp. ### ⭐⭐⭐⭐⭐ Fast, solid, good heat dissipation *by R***G on October 9, 2022* For a few weeks now, I been using a few Acasis NVMe M.2 enclosures for multiple Mac computer systems connected to Thunderbolt 4 ports. Especially the TB405 and the TB401 (for this specific review). The drives I have tested them with are the Samsung 980 Pro 2 TB and the Seagate FireCuda 530 4 TB. So far, the enclosure has been very reliable and fast (I mean fast …). For the Samsung 980 Pro 2 TB: - Blackmagic V3.4.2: o Write 2,817.2 MB/s o Read 2,708.6 MB/s - AmorphousDiskMark V4.0: o Read: 3,101.55 MB/s o Write: 2,937.15 MB/s For the Seagate FireCuda 530 4 TB - Blackmagic V3.4.2: o Write 2,612.9 MB/s o Read 2,625.3 MB/s - AmorphousDiskMark V4.0: o Read: 3,116.61 MB/s o Write: 2,722.06 MB/s The Samsung a little ahead for the Seagate FireCuda. The Aluminum casing sitting on top of my metal monitor stand does a great job dissipating the heat. We have used as well external SSD’s (Samsung T5 and T7). Both of those got constantly real hot and very uncomfortable to touch. Not so the NVMe with the Acasis enclosure. During video rendering the temperate does increase, but never to the level of the external SSD’s. Cost: This enclosure together with the fast Samsung 980 Pro 2 TB is less than $400, while the Samsung X5 is still at $900. Especially the TB401 is very easy to install, and the little extra work compared to an off the shelf solution, gets you great speed for less than half of the cost. Summary: This is a fantastic enclosure which works well with the Samsung 980 Pro and Seagate FireCuda 530. It provides excellent reliable speed with good heat dissipation. Just make sure to use the Thermal Pads to make contact between the drive and the enclosure (probably use both which are provided). Overall this enclosure is a solid winner. Personally between the two versions TB401 and TB405, I prefer the TB405. It seems to dissipate heat even a little better with the corrugated surface. However, the TB401 is easier and faster to install. Both are great! ## Frequently Bought Together - ACASIS 40Gbps M.2 NVMe SSD Enclosure, Tool Free Installation, TBU 401 for M1 M2 Pro/Max,Compatible with thunderbolt3/4/5,USB4/3.2/3.1/3.0/2.0, Support SSD Size 2280/2260/2242/2230 B+M M-Key (TBU401) - Samsung 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
