The 2019 model HDD interface is SATA III (6.0 Gb/s) so the SSD upgrade would be another SATA III (6.0 Gb/s) drive. The 2013 system has a PCIe 2.0 x2 blade SSD which is a much faster I/O channel than the SATA III.

The 2019 system, can’t support the addition of the PCIe SSD as the connector and support logic is not present on the logic board. In the case of the 2013 model the SATA connector is still present! So you could add a second drive (HDD or SSD).

Here’s the full specs for both systems:

Review this breakdown between the two.

There are enough Pro’s and Con’s for either! It all depends on what you are planing on doing. If you are doing photo or video work you’ll want the 4K display, while the i3 is a low end CPU the performance different is not that much as the year to year improvement over the 2013 is quite large.

The biggest negative is the lack of high speed internal drive support in the 2019 model (no PCIe support) But, it does offer a very high speed USB-C interface so one could setup an external drive which can be even faster than the internal PCIe interface!
