Windows 10 update could kill your SSD what you need to know
Microsoft is moving to fix an update that seemingly introduced a bug that could damage the lifespan of solid state drives (SSDs).
Bug-tracking site BleepingComputer reported that the Windows 10 May 2020 Update, aka version 2004, has been causing a suite of problems including one that messes with the ‘Defragment and Optimize Drives’ tool in the operating system. The bug means that Windows 10 version 2004 doesn’t record the last time an SSD was defragmented and optimized correctly.
This means that when the Defragment and Optimize Drives tool is used, it flags to users that the SSD needs optimization. As people tend to forget to do this manually, Windows 10 will carry out such tasks automatically.
But due to the tool not recording the defragmentations, it can end up defragging an SSD every time the drive gets rebooted, effectively defragging an SSD some 30 times more often than it really should be. This could ultimately damage the longevity of an SSD, slowly killing it.
Defragmentation effectively means pulling together fragments of data and packing them closely together with other bits of data they relate to. You could think of it as sweeping a pile of fallen leaves in a yard together — you still have the same amount of leaves in one space but they are now all together and easier to access at once.
There’s some debate as to how often you should defrag an SSD, with some arguing there’s no benefit to defragging an SSD like there is for a traditional spinning disk drive. But excessive defragmentation can affect the lifespan of an SSD. And that's the risk the bug in the Defragment and Optimize Drives tool poses.
A fix is coming
However, the Windows 10 Build 19042.487 (20H2) update, which is currently being rolled out to members of the Windows Insider program, promises to squash the bug.
People using the regular version of Windows 10 will have to wait for the update to pass beta testing, which shouldn't take too long. But in the meantime, it might be worth turning off automatic defragging to prevent running into the bug if it pops up on your Windows 10 machine.
