SMART’s numerical error code system provides more information about the drive’s specific calamity, but the broad headline delivered by macOS is enough for guessing how soon a drive will fail. “Failing” means the drive has an error that will soon become “Fatal,” which means the drive has failed. “Verified” means the drive has no reported problems. The SMART status appears at the bottom of the info pane. Select the drive you want to examine in the list across the top of the screen.Ħ. Click “Storage” in the list on the left of sections.ĥ. Click the Apple icon in the upper left.Ĥ. macOS keeps track of all your drive’s SMART status by default, and there are several tools that read this status with varying levels of detail. S.M.A.R.T (Self-Monitoring, Analysis and Reporting Technology) is an automated self-test system for SSDs and more traditional spinning HDDs. So it pays to keep an eye on the health of a drive that might suddenly and irreversibly fail without warning.īoth failure types can be predicted and planned for in advance based on certain characteristic failure patterns. When they fail, they fail completely: no data recovery is possible. They still have the same high rates of early failure like all electronic devices there’s a risk of mis-assembly and component failure.īut uniquely, the flash memory uses in SSDs can only survive a certain number of write cycles. SSDs, on the other hand, show a different failure curve. There’s a high chance of failure at the beginning and end of the service life (the walls of the bathtub), but a relatively low rate of failure in the middle (the base of the bathtub). If the drive spins up properly, then it will likely last for years before suffering a failure based on wear.
Spinning HDD drives have a failure curve sometimes described as a “bathtub.” When you first get an HDD, there’s a high chance of failure thanks to DOA units. To keep ahead of the game, macOS offers tools that can check the disk health of your SSD and other attached disks. That’s one reason backups are so important. Storage media of all kinds, SSDs included, is consumable.
