(It’s odd that the early write performance exceeds the read performance by so much, however. That means you’re getting an improved processor.
MACBOOK PRO 2018 VS 2019 PRO
Considering even the 2019 model is on the keyboard repair bulletin it doesn’t matter which one you go for. The good news is that for the US and Australia, the base model of the MacBook Pro 15-inch (2019) is the same as the 2018 model (2,399/AU3,499).
MACBOOK PRO 2018 VS 2019 MAC
Short of the PCI-based storage in your Mac Pro this appears to be the fastest storage in any Mac to date. If comparing like models, Between 8th and 9th gen CPUs not much of difference/gain, pretty much a rehash, that’s pretty much the main difference between the 20 MacBooks. Of course almost no one would have a task that requires this magnitude of data transfer in the real world, and even then the performance is still quite good, even with a slowdown.

The results for reads here are in excellent agreement with the test above: a bit over 5GB/sec, which is far above the ~3.3GB/sec achievable in prior Macs.

While similar in design, Apple made several improvements like high-fidelity speakers for dramatically improved audio, studio quality microphones, and the inclusion of Intel’s ninth-generation Intel Core i7 and Core i9 processors. Based on invoking the test a 2nd time, it appears that the SSD speed “regenerates” after the first test, so long as there is some time in-between. In late 2019, the new fifth generation MacBook Pro 16-inch officially replaced the previous generation 15-inch model. But when not degraded, the 7GB/sec figure is pretty awesome.įurther research is needed. Turning to thermal throttling as a theory, why the sudden plummet? With thermal throttling, one would expect a steady degradation, not an abrupt change.Įven the degraded write speed is in line with prior internal Mac SSDs (3.2 to 3.3 GB/sec) on iMac 5K, Mac Pro, etc. Which makes no sense for a 2-tier design (1/3 fast flash, 2/3 slower). The Dell Precision 7730 SBR30 (2018), however, while a very good choice at its 2,800 price point, falls just short of being remarkable.
The plummet occurs at file 479 of 1000, equating to 1331 GiB = 1430GB, or about 35% of the 4TB flash drive. The Apple MacBook Pro 16' 2TB, i7, 64GB RAM (late-2019) is one of the very best Traditional Laptops that one can get for around 4,000.
To see an abrupt breakdown in SSD write speed for sustained writes suggests a 2-tier flash drive. Write behavior is unlike anything MPG has ever seen in an Apple internal SSD.
