| M2 Air (512GB) | ~3,500 | ~2,500 |
The benchmark results consistently show that the M2 Air with 512GB SSD outperforms the M1 Air in both sequential read and write speeds. The M2 Air achieves a significant leap in sequential read speed, surpassing the M1 Air by about 700 MB/s. This advantage is particularly noticeable when transferring large files, like video editing projects or game installations. The M2 Air also exhibits a substantial improvement in sequential write speeds, exceeding the M1 Air by approximately 500 MB/s. This translates to faster file saving and overall smoother workflow in demanding applications.
Random Read & Write Speeds:
| Model | Random Read (MB/s) | Random Write (MB/s) |
|---|---|---|
| M1 Air (512GB) | ~2,000 | ~1,500 |
| M2 Air (512GB) | ~2,500 | ~2,000 |
In terms of random read and write speeds, which are critical for multitasking and accessing smaller files, the M2 Air again emerges as the victor. The M2 Air's random read speed surpasses the M1 Air by approximately 500 MB/s, while its random write speed shows a notable 500 MB/s improvement. These gains translate to faster application loading times and quicker file access, ultimately enhancing your overall productivity and user experience.
