2015 Apple MacBook: IntegrityChecker Verify Hashes

12-inch MacBook (2015, gold)

Get Apple MacBook> and Save on AppleCare at B&H Photo.

B&H Photo loaned MPG the latest top-end MacBook with 1.3 GHz processor, 8GB memory, 512GB PCIe flash drive along with a USB-C to USB adapter (even better: Apple USB-C Digital AV Multiport Adapter and most users will want both).

√ Get the OWC USB-C Dock for MacBook.

This is a real world test influenced by both CPU cores and SSD/flash drive speed; IntegrityChecker has few peers in its optimal use of CPU cores, but the 2015 MacBook has only two cores and a slower SSD versus 4 cores for the 2015 MacBook Pro Retina.

The MacBook does relatively well here considering its turtle-slow CPU clock speed of 1.3 GHz: it takes 2.8X as long as the MacBook Pro Retina. Its CPU cores are fully utilized, as are those of the MBPR, but the SSD speed differential gap is not as high since there are so many files to read; this adds some file system latency to the process. Hence 2.8X instead of 4X or so that should be seen with large files (more efficient I/O).

Real-world task: verify file integrity using IntegrityChecker verify on 158K files totaling about 76GB
