Multiple erases On MBP : Is it harmful

I was resetting my MacBook Pro frequently so that maybe I erased it more than 10 times some using settings and other using disk utility, how to check if the ssd would fail because of that and naturally would that make ssd fail?

MacBook Pro 16″, macOS 12.2

Erasing the ssd multiple times is not necessarily damaging to the drive. SSDs are designed to provide many years of service, and whether that service is as a startup drive or an external drive, the service may include multiple erasures over the life of the drive. These erasure should not cause a relatively new drive to fail anytime soon.


My big question is: Why are you so frequently resetting the computer?

That shouldn't be necessary under normal circumstances. If you are having some problem, then maybe the best course of action is to figure out what is causing it and eliminate the problem.

Some previous calculations on typical lifetimes of SSD devices suggest you may have drastically reduced the expected lifetime of your SSD drive, BUT (wait for it)...




...from 60 years of typical use to about 59 1/2 years of typical use.


As D.I. Johnston stated, Readers are eager to understand why so many erase cycles were necessary, and ready to help with the underlying problems that drove you there.

Using Disk Utility in macOS to erase your SSD only modifies the structure of the partition & only writes a minimal amount of data to the drive. So there is no huge wear & tear on the SSD with the Disk Utility erase....the real wear comes from installing macOS which writes 20GBs of data during the install....more when restoring your data from a backup.


Trying to securely erasing an SSD by writing zeroes to the entire SSD is what causes the excess wear for no reason at all since it is impossible to access all of the SSD's storage cells due to how SSDs work (Disk Utility hasn't allowed a secure erase of SSDs for years). Many SSDs have a built-in hardware secure erase/sanitize feature, but that requires the use of the vendor's proprietary software to access it or a Linux system.


When you encounter issues with your Mac, you may want to run the third party app EtreCheck and post the complete report here so forum contributors can provide an analysis of the report to attempt to figure out the cause of any issues.
