<![CDATA[Opera writes a lot on HDD]]>Opera (latest version) writes huge amount of bytes on HDD, several days of using (laptop hybernated over the night) made about 80 Gb written to HDD. With SSD it is a noticeable problem because of a limited resource. Anyway, I cannot understand, what is that browser needs to write on HDD of such size??
And, how to fix this?

I remember a topic with a local storage issue. A particular site was the culprit.

This is exactly the issue I have with one of the large Swedish news sites. If I go to www.dn.se, Opera (28.0.1750.48 atm.) keeps writing to local storage over and over and over. I cannot see any similar behavior in Firefox.

I like Opera 12. You can disable CACHE there and no problem with briking your SSD. I think you should go with firefox now - I think you can there disable cache on disk without aany of magic voodoo recipes like it now by chromium, newest opera etc...or go to old Operea 12...but i would go with firefox with disabled disk cache or even with chromium with run string --disk-cache-dir="nothing"...or stay with old good op12 - for me its enough advanced and works everything what I need. Bye.

  • You downloaded 300, but it's written 8G. How come?

Years ago they were an independent project but over time the utils became so good that MSFT hired the author, made him one of their top TechNet technical evangelists, and bought the code.

    Between ProcessMonitor, DiskMon, and ProcessExplorer, you should be able to track down what is doing your read/write activity.

    Also see and check out the utilities from NirSoft.

Perhaps you can use it to see if one of your processes has an abnormally large impact for some reason.

    Also, did you try closing tabs one by one to see if that effected anything?

    Anyway, according to Windows Task manager the Opera itself produces the disk activity.

I currently have 3 windows up with about 25 tabs spread across them and the read/write state of my SSD is flat at zero. Thats my OS and Application drive and it is where Opera is installed and its cache is located. So, whatever you are experiencing is not normal Opera behavior.

    I'd try closing tabs and checking your system to see if it goes away when a specific website is closed. Either that or go into Opera menu > Developer > Task manager and add the different chase types to the display and see if anything funky is going on.

I believe I have installed only Adobe Flash, but I cannot see it there.

    I just have Opera always opened at the background. There are a lot of opened pages, I believed they automatically reload
    ofter but I have only 300 MB downloaded in 11 days, according to wifi info. I have restarted Opera with the newwest update, just about half an hour ago and it has already written 1GB and keeps writing about 30-50 Kb. each second.
