SSD Health Monitor for Mac

Solid State Drives are the new normal. If you have a Mac made in the last 10 years, it probably has an SSD. If you’re seeking optimal performance and longevity from your solid state drives, Lifespan offers valuable insight into the remaining life of these drives.

Given that flash-based storage devices have a limited operational life, surpassing this lifespan might lead to gradual performance degradation or even complete failure. Understanding the remaining usable life, particularly with intensive usage, is important.

Most SSDs employ non-volatile NAND solid state memory to store data. Each cell within this flash memory has a limited number of programmable and erasable cycles known as program/erase (p/e) cycles. The quantity of these cycles can vary, ranging from under 2,000 to over 10,000, contingent on the type and quality of NAND chip. As an illustration, a mid-range solid state drive offers approximately 250 TB written of effective lifespan, though this can vary significantly. Regardless, every flash-based storage device inevitably reaches a point where it can no longer store data, culminating in device failure.

Lifespan is an innovative macOS Menu Bar application designed to monitor the remaining useful life of flash-based storage devices. Our software conveniently displays the remaining lifespan of your solid state drive (SSD). The Lifespan menu displays the current lifespan of each supported SSD, and will promptly alert you as the remaining life approaches a critical threshold. Armed with this critical information, users can retire their flash-based storage devices preemptively, mitigating the risk of potential data loss. Experience peace of mind with Lifespan.
