Windows 11 SSD slowdown bug has been hanging around for months – and people are fed up

Hey, Microsoft: SSD stands for solid-state drive, not super-slow drive

Windows 11continues to have a problem for some users whereby their SSD speeds are being seriously slowed down, and it’s still not clear whatMicrosoftmight be doing about this issue.

Windows Latesthighlights the ongoing stream of reports about SSD slowdowns whichfirst began back in March 2023(with update KB5023778).

Since then, after every cumulative update forWindows 11, including the update for June, there have been folks complaining about performance being hampered with even thebest SSDs.

That also includes the June preview (optional) update, which will become the July update a week tomorrow (July 11), and so is very likely to carry the problem.

Windows Latest points to a whole string of complaints on Reddit and Microsoft’s Feedback Hub for Windows 11 (as well as the tech site’s own forums).

Here’s one example of an affected user onReddit: “Yes, I only encountered this issue after I installed the Moment 2 update [March update] before Moment 2 everything was fast and responsive. To this day none of the patches fixed the bug for me. Microsoft should really fix game-breaking bugs before working on releasing new features.”

With the latest preview update for June (that’ll become July’s update, as mentioned), another complaint runs likethis: “Oh, so there actually is a storage bug going on? My NVME SSD has around 1200 MB/s sequential write speed right now, it should be up to 4400 MB/S. Read speeds are normal.”

Analysis: Let’s have some communication here, Microsoft

We have to agree with the Windows Latest report, as we’ve definitely noticed that with the notes for every patch release on Reddit, there’s an SSD complaint in there somewhere. Either someone new hit by the issue, or people asking if the slowdown gremlin has been fixed for other folks, as it hasn’t for them. Invariably, the answer is no, it hasn’t.

So, what’s Microsoft doing about this? We’ve not seen any official replies on those mentioned threads, and according to Windows Latest, Microsoft has confirmed it has received these bug reports, but hasn’t said anything further. That’s far from ideal, of course, even if this isn’t a hugely widespread problem (we’re not entirely sure of the scale of the numbers of those affected, but there are certainly a fair few folks out there complaining).

Needless to say, those in that particular boat are none too pleased, and are bemoaning Microsoft working on new features – and lauding the likes ofDirectStoragefor speeding upPC gamesand SSD loading speeds – while leaving a flaw like this apparently unaddressed over a period of months now.

Microsoft can surely do better, if not in delivering a fix for what seems to be a pretty clear problem at this point, then at least in letting us all know what’s going on. As of right now we don’t even know if this is on any priority lists for being investigated, let alone resolved.

If we had to guess, the drive slowdown problem may be tied to multiple issues – which is perhaps why new folks seemingly keep finding themselves affected down the line – and this is a messy one for Microsoft to untangle. It’d be nice to get an update on exactly what’s going on to tackle this, though, and hopefully we’ll see that soon enough.

Meanwhile, your only recourse if affected is to uninstall the update that caused the SSD to hit performance issues. But of course, that leaves you without the latest security fixes, which could be an even bigger problem ultimately, if you get unlucky.
