How come my MacBook Pro 16″ has internal SSD speeds of 2800 MB/s Read/Write while my external Samsung T5 SSD only goes up to about 500 MB/s?

Question

How come the difference is so huge? And are there any faster alternatives?

Answer 1

Due to the connection type you can achieve huge differences. Most external SSD use SATA, like HDDs, and only achieve around 500-600 MB/s. However, with M.2 drivers NVM can get a lot faster, as high as 3200 MB/s, like most premium computers nowadays, for instance your MacBook pro and dell xps.
