Just wondering, can read/write cycles on a Macbook's internal SSD be avoided by downloading files from the internet to an external hard drive?
I'm not sure how macOS handles this so I'm wondering:
- Does downloaded file content go directly to the external drive, or does it pass through a cache or similar buffer on the SSD first?
- Does the method of calling the download matter? For example, initiating download via Safari, via a download manager, via terminal?
- Aside from the problem slower speed of downloading resulting from the slower read/write rate of the external drive, would downloading to the external drive help in the lifecycle of the SSD or is this a pretty useless way of preserving it?
