Removal of USB drive that is "optimized for quick removal"

Posted on 2014-08-29

Using several Windows 7 Pro x64 machines.

I am trying to find out how effective the option for "optimized for quick removal" is.  

Some threads say this disabled write caching and therefore there is no need to use the "safely remove option.

Other insist on continuing the original practice of using safely remove for every USB device.

Would appreciate hearing what the experts have to say on those options.  

It seems like, by default, every USB device plugged into Windows 7 get set to "optimize for quick removal".

    "Life is too short to safely remove USB."

    All joking aside... Yes, Windows 7 by default sets the "Quick Removal" option (see screenshot). If you opt for the better performance option, you need to safely remove the USB or you risk data corruption.

    here is a pretty good article that explains the cost benefits

    However i would consider how you use the usb drive in the first place. If it is a considerable factor that maybe having something you can easilty remove or knock out is not a great method and maybe using something like a card reader may work better

    If a program is accessing the USB stick while you pull it, the file-system on it can still go corrupt, even with quick removal enabled. So you must make sure all programs that would be accessing it aren't running or aren't accessing it. When you hit the safely remove option, you at least get a warning if the stick or disk is still in use.

    Try to buy usb devices with indicators (led lights). Also buy faster devices, do research about the actual real world transfer speeds (don't look at just the speed stated by the manufacturer, as these are theoretical top speeds), preferably from other users who already have the device.
    That's because no matter what settings you are using, if you've copying 1 GB of data, no matter what settings, you are definitely waiting seconds if not minutes before you can safely remove it (either just removing it, or using the safe removal method in Windows). That's where the faster device will come in handy. The blinking light will tell you when it's really done or not).

    Thanks to every one for the quick replies.  MS makes it sound all too easy to just set the quick removal  option and yank it whenever you want... but lots of caveats to that as most of you pointed out.
