Sequoia 15.3 results in significant improvements in read-write speeds of SSDs connection through Thunderbolt 5 docks and hubs. Here are the details and implications for choosing SSDs.
TB3
Early testing of TB5 SSDs show they do deliver much faster speeds that even USB4 models, although not as high as some claim. But their cache size may limit streaming large amounts of data.
TB5 promises twice the data transfer rate of TB3, and three times that when supporting external displays. How close is it to achieving those?
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?
You pay hundreds of $$ for a high-speed Thunderbolt SSD, then connect it to a hub. Will it still deliver the same performance? Maybe not when writing.
Do fast Thunderbolt SSDs slow down when connected via a Thunderbolt hub? How fast are they when reading at the same time? Does connecting a display affect them?
Although little more expensive than good Thunderbolt 3 cables, what are the differences in Thunderbolt 4? When do you need a new TB4 cable?
