Major I/O write bytes on the Spotify Desktop app. It will kill SSD drives in record time (fixed)

EDIT: According to Spotify this issue has been fixed in the 1.0.42 version so the case has been closed. Personally I have no more issues with this anymore on any computer. Thanks everyone for making this happen !!!


original post:
Major disk write activity detected on the Windows/Mac app. Does not behave like that when using the browser player.

Please look into this thread, more details there:


Attached readouts from a Win7/64 PC during one hour and ten minutes. No offline playlist syncs and zero songs were played during that hour, only the spotify app tray active in background!

No disk drive, SSD or standard HDD can take that rate for a long period of time.




Thank you for bringing this issue to our attention. As some of you have noted, the prior version of the Spotify desktop client may sometimes have caused unnecessary data to be written to storage devices. This issue has been fixed in the current version of the desktop client (1.0.42), released November 11th, and rolled out to all our users. If you try to run an older version, you will see it automatically restart and update to the new version shortly after you log in.
If for some reason you should encounter problems with the auto update, just follow these steps to perform a full reinstall.

If you're running a deprecated OS (Windows XP, Vista; OS X 10.7, 10.8), don't worry. A fix has automatically been rolled out to you too. To ensure you're running this version, just close/reopen the desktop app twice.

Again, we greatly appreciate your help here, and hope that you will continue to flag issues for us when they arise.

I recently noticed that something was writing a lot of data to my SSD so I started looking trough what could be causing it, and Spotify ended up being the culprit, it was writing close to 10GB an hour to my drive at one point.


I checked the I/O write data with the S.M.A.R.T data on my drive and it wrote 28.305.469.806 Bytes of data in about 2 and a half hours, I've also noticed that it only writes the data when playing music, still completely unacceptable.  


I just reinstalled and tested again, and got it to use 1GB in 17 minutes. (and according to S.M.A.R.T that was indeed written to my SSD)

and another one using 320MB in 4-5 minutes.

While this is a heavier usecase than I would typically present to Spotify.


The issue at hand seems to be that it tries to cache every song you play as when I went back to a song that I played at the start of the tests it wouldn't go up, but that still doesn't explain that one time it used 28GB (or about 26GiB) while listening to a song on auto replay.


I didnt have this problem a couple of months ago, but started noticing it around may.


I'm very dissapointed with this issue because it makes me have to avoid software I used to love.

Isn't installing Spotify in a regular HDD an option?


The issue with that is that I have a laptop atm so I can only have one drive


Ok, I see.

It's normal for any application to write files to the disk like caches and other stuff.

Now, around 30 gigabytes of data is a lot. I tested in my PC and Spotify doesn't use that amount of data, not nearly close.
Are you sure it wasn't syncing offline tracks in the back without you noticing?


I mean it could've been doing that, but 30GB is a bit much, I definitely don't have that many songs as available offline (spotify has 1GB or so stored on my SSD)


I'm seeing this same thing. Spotify is writing over 100GB per day to my SSD....yes, 100GB! That will kill my SSD in under a year and it would severly strain a mechanical drive too.


There's no reason whatsoever for this kind of behavior and I see multiple people mentioning this on these forums without any resolution.


Yes, streaming music is going to use some disk IO but this is totally unacceptable. How can streaming a few hundred MB of music use hundreds of GB in disk writes?


There's something really really wrong here.


I left Spotify open last night, just idling, not streaming anything and it wrote 50GB to my drive.




Same issue here, I listened to like 30 different songs during the day and it wrote 50 GB worth of data.


For now I'll be forced to use the Web Player until they fix this.


Something is definitely wrong with the Win app at the moment. If this wont be fixed soon I will cancel my account and switch to another service. It will be way cheaper than to replace (and re-install) all computers at home & work. SSD's cant take this write rate.

And the weird thing is its doing it even on idle. Someone dropped the ball at Spotify and this needs an explanation for sure. I just clocked 3,4Gb in 50 minutes. And I was in a meeting during that, no stream no offline syncs. During that same time Firefox wrote 290Mb with 7 tabs open so **bleep**..?!
