Spec Comparison: 40Gbps vs 80Gbps
transfer speed
The ACASIS 80Gbps NVMe Enclosure leads in raw throughput. It supports up to 80Gbps via Thunderbolt 5 or USB4 V2.0. This allows read and write speeds reaching 6000 MB/s with PCIe 5.0 drives. The ACASIS 4-Bay 40Gbps SATA and NVMe Enclosure caps at 40Gbps. You get this speed only when using two NVMe SSDs in RAID mode. Both units require compatible host ports. The 80Gbps model offers double the bandwidth ceiling for future-proofing large file transfers.
drive compatibility
These enclosures serve different storage needs. The 80Gbps NVMe Enclosure supports only M.2 NVMe SSDs, including PCIe 5.0 models. It is tool-free and accepts 2230 to 2280 form factors. The 4-Bay unit is a hybrid design. It houses two SATA bays for 2.5-inch and 3.5-inch drives, plus two NVMe bays for 2230 to 2280 SSDs. You can mix high-speed SSDs with high-capacity HDDs. This makes the 4-Bay model more versatile for mixed workloads requiring both speed and mass storage.
host interface
Connectivity options differ significantly between the two. The 80Gbps NVMe Enclosure uses Thunderbolt 5 and USB4 V2.0. It explicitly excludes Thunderbolt 3 compatibility. The 4-Bay SATA and NVMe Enclosure uses USB4 and supports Thunderbolt 3, 4, and 5. If you have older Thunderbolt 3 hardware, the 4-Bay unit works immediately. The 80Gbps unit requires newer ports to achieve its maximum speed. Both offer backward compatibility with USB4 V1.0 and USB 3.2 standards.
power delivery
Power management features vary by use case. The 80Gbps NVMe Enclosure includes 60W Power Delivery. You can charge a compatible laptop while transferring data through a single cable. This is useful for mobile workstations. The 4-Bay SATA and NVMe Enclosure uses a separate 96W power supply. It does not list PD charging for host devices. The dedicated power brick ensures stable operation for multiple drives, but requires an extra outlet rather than bus power.
cooling system
Both units use active cooling to manage heat. The 80Gbps NVMe Enclosure features an intelligent auto cooling fan. It adjusts speed based on SSD temperature automatically. The 4-Bay SATA and NVMe Enclosure also includes an active cooling fan inside an aluminum chassis. Both designs help maintain performance during sustained workloads. The 80Gbps model emphasizes smart adjustment, while the 4-Bay model relies on its aluminum build and fan. Neither requires manual fan control.
