No heating issue observed so far. Using WD SN770 2TB with my mac studio m1 max. Giving expected read and write speeds. Value for money product. ### ⭐⭐⭐⭐⭐ Fantastic SSD enclosure! *by on Reviewed in the United States 26 August 2025* I am blown away by the speeds that this SSD enclosure can deliver. I've got mine paired with a Samsung 990 PRO 4TB SSD and plugged into the Thunderbolt port of my Mac Studio. I'm seeing read/write speeds in the 2700 MB/s and 2600 MB/s range, which is so much faster than my previous 10 Gbps enclosure (which was achieving roughly 600-700 MB/s speeds). And this is with the SSD about 45% full. I use my system for video editing 4K content, and the scrubbing speed on my timeline has become instantaneous. I can quickly scrub through the timeline or jump to different parts of the video with ease... no lag anymore!Installation was super easy... just open the fully aluminum case, insert the SSD and rubber mounting plug, then push the SSD into the enclosure (no screws or screwdrivers needed). Close the cover and you're done. My Mac recognized the drive immediately. The enclosure can get warm (to slightly hot) when I'm rendering a long duration video, but that's expected of any SSD or hard drive. To keep the enclosure (and SSD) cooler, I keep the enclosure on top of my Mac Studio (which has an aluminum shell)..... this helps to dissipate heat a little better than if I were to place it on my wood desk surface.The enclosure looks great; it's sleek and minimalistic with cleanly milled heat-sink grooves. And the all-aluminum design is very-nicely machined and matches the design language of my Mac, awesome! I don't have a PC, but this is fully compatible on my Mac Studio running the latest MacOS. ### ⭐⭐⭐⭐⭐ Best product and achieved results as per product description *by on Reviewed in India 21 June 2026* Easy install and plug and play product ,with samsung 980 NVMe M2 i was able to achieve 2754 MB/s Read & 2802 MB/s write speed perfect for 4k video editing directly from external ssd instead of copying to my local.Best product and very much satisfied. ## Frequently Bought Together - ACASIS 40Gbps M.2 NVMe SSD Enclosure, Only Compatible with Thunderbolt 4/3 USB4,TBU405 Air for M1 M2 Pro/Max, Tool Free Installation, Support M-Key Interface B+M 2280/2260/2242/2230 SSD Size - Samsung 990 EVO Plus SSD 2TB, PCIe Gen 4x4, Gen 5x2 M.2 2280, Speeds Up-to 7,250 MB/s, Upgrade Storage for PC/Laptops, HMB Technology and Intelligent Turbowrite 2.0, (MZ-V9S2T0B/AM) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/684853778-acasis-40gbps-m-2-nvme-ssd-enclosure-tbu-405air-m1](https://www.desertcart.jp/products/684853778-acasis-40gbps-m-2-nvme-ssd-enclosure-tbu-405air-m1) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-21*
