## Customer Reviews

### ⭐⭐⭐⭐⭐ Works like a charm
*by V***I on 13 May 2025*

Works like a charm. 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.

### ⭐⭐⭐⭐⭐ Good product
*by L***L on 4 July 2025*

The product is excellent and works as expected. It’s got a premium feel with the aluminium body and heat distribution.

### ⭐⭐⭐⭐ ⭐️⭐️⭐️⭐️☆ Excellent Thunderbolt 3 SSD Enclosure for Mac Mini — but no cooling fan as claimed
*by R***H on 9 October 2025*

I bought this Thunderbolt 3 SSD enclosure (Model B0DD34LH8R) to upgrade my Mac Mini M4, which came with only 256 GB of storage. I paired it with a 2 TB WD Black M.2 SSD, applied the thermal pad(both side of the ssd) (heat tape), closed the case, and cloned my internal SSD using Carbon Copy Cloner (CCC). After switching the boot drive, my Mac now runs from the external SSD smoothly — effectively turning it into a 2 TB Mac Mini without paying Apple’s huge storage premium. Performance is excellent — I get around 2800 MB/s read and write speeds, which matches the Mac’s internal drive speed since it’s already throttled around that level. Thunderbolt 3’s 40 Gbps bandwidth is fully utilized. However, the product description says it has a cooling fan, but it actually doesn’t. That’s misleading. Fortunately, the aluminum body and heat pad manage temperatures decently, but under heavy transfers it can get warm. ✅ Pros: True Thunderbolt 3 performance (~2800 MB/s) Solid aluminum body and premium build Easy setup and bootable on macOS ⚠️ Cons: No fan despite the claim Gets warm during long transfers Overall, still a great enclosure for Mac users, but the missing fan description needs correction.
