UPDATE:technology like this is wonderful: fast beyond measure and totally silent. See the blazingly-fast performance of the OWC Accelsior 4M2 PCIe SSD.
A dream of mine is now fully realized: no more noisy 'spinners' (hard drives) except for backup!
With the 16TB OWC Accelsior 4M2 PCIe SSD as main storage along with the 8TB internal Apple SSD (24TB SSD internal total), I now can store all the data and images I’ve ever created in my life, on internal SSD storage, with room to spare for ~2 years to come.
And with dual 8TB OWC Thunderblade external SSDs, I have another 16TB of SSD storage, which is ample for several more years of 100MP and 150MP cameras. For now I can use them for clone backups and travel storage.
Over the next few days, I’ll be reporting on performance (outrageously fast) and how I’m utilizing the OWC Accelsior 4M2 PCIe SSD in my 2019 Mac Pro as main storage. The OWC Accelsior 4M2 is an awesome choice for video use too, ditto for the OWC Thunderblade.
Regarding the 2019 Mac Pro for professionals, it is by far the best Mac out there for outstanding flexibility and my recommendation for professionals is to apply risk mitigation by avoiding ARM-based Macs and required macOS Big Sur until they are well established.
