2016 MacBook Pro: IntegrityChecker Verify

Mac wish list all 2016 MacBook pro models at B&H Photoall 15" Apple MacBook Pro 2016 models • all 13" Apple MacBook Pro 2016 models. MPG gets credit if you buy through those links.

MPG tested a fully-loaded 2016 MacBook Pro with 2TB SSD.

DiglloydTools IntegrityChecker runs SHA1 hashes on files to maintain data integrity checks.

Its verify command utilizes all CPU cores as efficiently as any application ever can, using sophisticated I/O algorithms to feed data to the CPU as fast as the OS can go. Performance will thus be gated by I/O speed unless all CPU cores are fed data fast enough to be fully utilized.

Results

The results reflect the hyper-fast SSD of the 2015 iMac 5K and the 2016 MacBook Pro. But with only 4 cores, the fastest CPUs win, since both machines supply data faster than 4 CPUs can process it. Thus the iMac 5K is the fastest, even though the 2016 MacBook Pro has a faster SSD.

Te 2016 MacBook Pro laptop is within 17% of the 2015 iMac 5K desktop — impressive.

Both the late 2015 iMac 5K and 2016 MacBook Pro trounce the aging 2013 Mac Pro, whose SSD dodders along at around 1100MB/sec (versus 3X and 2X that speed for the MBP and iMac). This just kills the performance for the Mac Pro.

The 2013 MacBook Pro has the slowest SSD of the bunch (about 750 MB/sec), but that it equals the Mac Pro performance speaks volumes about how out of date the Mac Pro hardware is.

* Models of the 2013 Mac Pro built in 2015 or so or later may might have somewhat faster SSDs. The 3.3 GHz 8-core Mac Pro used for this test is faste than any model that can be purcahsed at Apple.

IntegrityChecker verify 139.25GB data in 207098 files

Test machine notes

All systems are/were the fastest available in their category. All running macOS Sierra 10.12.1.
