There’s a big difference between the storage that’s available, and what’s advisable. Whether it’s affordable is another question.

Why should you trim an SSD? How to tell whether an SSD needs trimming, finding out whether it has trim support, and whether it does trim.
Enabling the TRIM command was once thought important to maintain good write performance on SSDs. What has happened to it? Should we still be enabling it?
Traced from recognition of the cable connection, through establishing PCI streams, to mounting the volume with APFS, and the bonus of a good trim at the end.
In the worst case, an expensive TB3 SSD with a regular write speed of 2.2 GB/s could only write at 400 MB/s when connected via a hub and contending with faster SSDs.
Is the performance overhead of using APFS Encrypted volumes to store sensitive data a reason for not doing so?
From choosing cables and hubs to connecting displays, fast SSDs and other devices. Everything you wanted to know about Thunderbolt.
What happens to read and write speeds of three SSDs connected to the same hub, and working at the same time? Can they exceed the maximum of 3 GB/s?
If you have more than a couple of Thunderbolt peripherals, should you be thinking of getting a Thunderbolt 4 hub?
What happens when you connect two fast SSDs to your Mac and they both write or read at the same time? How do they perform when connected through a hub? And how does it pay to be a winner?
