ACASIS vs ANYOYO Enclosure Specs
Active cooling
The ACASIS enclosure features an active cooling system with a built-in silent fan. You can press a switch to activate this function, which works alongside an aerospace-grade aluminum alloy body and a high-conductivity silicone thermal pad. This triple heat dissipation system aims to maintain optimal performance during high-intensity workloads. In contrast, the ANYOYO enclosure relies solely on passive cooling. It uses an aluminum alloy shell and a silicone thermal pad to absorb and disperse heat. This design ensures quiet operation with no noise, but it lacks the forced air movement provided by the ACASIS fan. If you prefer silent operation, the passive approach may suit you better.
Physical dimensions
Both enclosures share the same width of 2.24 inches, but their other dimensions differ. The ACASIS model measures 4.65 inches in length and 0.71 inches in height. It weighs 4.83 ounces. The ANYOYO enclosure is shorter at 3.94 inches in length and thinner at 0.55 inches in height. However, it is slightly heavier at 5.29 ounces. The ACASIS unit is longer and taller but lighter. The ANYOYO unit is more compact in length and height but denser. You should choose the ACASIS if you need more length for cable management or airflow. Choose the ANYOYO if you prefer a smaller footprint that fits more easily into tight spaces or pockets.
Controller chips
Both enclosures utilize the Intel JHL7440 controller chip, which supports Thunderbolt 5, Thunderbolt 4, Thunderbolt 3, USB4, and USB 3.2. This ensures dual-chip reliability and stability for high-speed data transfers. The ACASIS product description highlights this single chip as the core of its reliability. The ANYOYO enclosure also uses the JHL7440 but adds the RTL9210 chip for additional control. This dual-chip configuration in the ANYOYO unit is designed to ensure seamless compatibility and flawless transfers across Windows, macOS, and Linux. Both provide robust connectivity, but the ANYOYO lists an extra controller for broader management.
Transfer speeds
Both products advertise a maximum transfer rate of 40Gbps. The ACASIS enclosure cites tested read and write speeds of up to 2805 MB/s and 2734 MB/s, respectively, using a Samsung 980 Pro on a MacBook. The ANYOYO enclosure states read and write speeds can reach up to 2700 MB/s, also referencing testing with a Samsung 980 Pro through a MacBook Pro. While both claim similar peak bandwidth, the ACASIS lists slightly higher specific throughput numbers in its marketing data. The ANYOYO emphasizes transferring 2.5 GB files in seconds. Actual speeds will depend on your host device and SSD capabilities.
Installation style
The ANYOYO enclosure explicitly advertises a tool-free installation style. This feature allows you to insert your M.2 NVMe drive without needing additional hardware or screws, simplifying the setup process. The ACASIS product data does not mention a tool-free mechanism or specific installation hardware. It describes the enclosure as compact and portable but omits details about how the drive is secured inside. If you value quick swaps and easy access to your drive without searching for tools, the ANYOYO provides a clear advantage. The ACASIS may require a different method to secure the drive, which is not specified in the available data.
Drive compatibility
Both enclosures support M.2 NVMe drives in 2230, 2242, 2260, and 2280 form factors. The ANYOYO enclosure explicitly states support for both M-Key and B+M Key NVMe drives and confirms it does not support SATA NGFF or mSATA drives. It also supports capacities up to 8TB. The ACASIS data confirms support for the same form factors but does not explicitly mention B+M Key compatibility or a maximum capacity limit. Both are compatible with Mac, Windows, and Linux systems. The ANYOYO provides more specific details regarding key types and capacity limits, offering clearer guidance for drive selection.
