Thanks to the internal data transfer rate of up to 2750 megabytes, the combination of an Acasis TBU-405 enclosure and a Sysor ZD1 PCIe Gen 4 x4 NVMe SSD offers affordable, fast external storage which exceeds that of the built-in M2 Mac mini. The standard M2 Mac Mini provides a maximum of around 1700 megabytes and its 512 Gigabytes version is around 2700 sust. Hence, it is more effective and also a better option cost-wise to use an external hard disk drive.
