Apple's newly released M5 MacBook Pro may look almost identical to its predecessor on the outside, but it packs a serious punch under the hood with a remarkable surge in solid-state drive (SSD) performance. Technology review firm MaxTech, using the Blackmagic Disk Speed Test tool, discovered that the M5 model's SSD sequential read speed soared to 6323MB/s when compared to the M4 MacBook Pro. This marks a staggering 211.3% increase. Its write speed also jumped to 6068MB/s, up by 84.31%, putting its performance on par with desktop-grade independent PCIe NVMe Gen4 solid-state drives. This performance leap is credited to the use of a new generation of 3D NAND flash memory particles, specially designed controller chips, and an upgrade in unified memory bandwidth. These enhancements significantly boost efficiency for demanding tasks such as video editing and loading virtual machines. However, it's worth noting that performance varies across different capacity versions. Write speeds hover around 5200MB/s for the 1TB and lower capacity models, while only the 2TB and higher versions can achieve the peak performance.
