Some M1 Mac users report excessive SSD wear and tear. Here's what you need to know and how to check the health of your drive.
Apple uses the M1 chip in most of its computers these days. The company has also largely switched MacBook and iMac models to solid-state drives (SSDs). And while these changes are both great, they aren't without their problems.
Some users reported in February 2021 that their M1 Macs were wearing out their SSDs very quickly. It is possible for these drives to fail within the warranty period.
The following explains how SSDs work, what's wrong with the M1 Macs, and how you can check your Mac's SSD health. That way, you can fix problems before your drive is completely worn out.
How SSDs work
SSDs are a type of flash memory in which data is stored in a cell grid. They have no moving parts and are faster than hard drives.
The cells in an SSD are used and reused as files and data are created, accessed, and deleted from your computer.
However, this writing and rewriting process can only take place so often. An SSD has a limit known as TBW, which stands for "Terabytes Written" or sometimes "Total Bytes Written". When this TBW limit is reached, the SSD slows down and a computer takes longer to access files and data.
As such, SSDs are expected to wear out over time. If not replaced before they are completely worn out, they can even stop working altogether. This means that data stored on them can only be called up if they have been backed up elsewhere.
Problems with the M1 Mac SSD
The problem some M1 Mac users have had is that their SSDs wear out much faster than an SSD.
These computers appear to be consuming 10 to 13 percent of their SSD's TBW limit in less than a year. People on Twitter and MacRumors have reported that they wrote 150TB of data to their SSD after just two months.
Hence, these users could see their SSDs failing incredibly soon. SSDs can be replaced or upgraded, but they are expensive, especially on newer Apple computers that do not allow user upgrades. In the meantime, users might suffer from their computers slowing down fairly quickly despite the speed advantages of the M1 chip.
Here's how to check your Mac's SSD health
This SSD wear issue doesn't seem to affect every M1 Mac computer. However, if you have an M1 Mac, you should probably make sure that your SSD is working normally.
You can check the SSD health of your computer in the system report. To access the system report, click Apple symbol at the top left of your screen. Press and hold the button possibility Key, then click System information to open the report.
Click to view your SSD warehouse under the hardware Header in the left sidebar. You can find the name of your drive under Volume name and can see differently Assembly points for this.
Click on the name of your drive and look for the CLEVER. Status (self-monitoring, analysis and reporting technology) Section at the end of the report.
If the CLEVER. status is VerifiedYour drive has no problems. If the CLEVER. status is to failthe drive has a problem. In case you see one to fail Status, back up your Mac ASAP and prepare to replace the SSD. You should contact Apple Support.
If the CLEVER. status is Fatalthe drive has already failed. In this case, you have probably already lost data. Back up whatever data you can and contact Apple to get a repair straight away.
A rare Mac problem
As mentioned above, not every M1 Mac owner has reported that their SSD wears out quickly. So far it seems to be a relatively rare issue and hopefully it won't plague this generation of Mac models.
Since the consequences of the problem can be severe, it is important to make sure that your M1 Mac's SSD is healthy. Keep an eye on it over time to make sure it doesn't wear out prematurely.
