Short Description:

This video covers how to modify the Windows 8 hard drive write caching setting. By default, this setting may be enabled or disabled depending on if you are running a desktop or a laptop. The only risk of running hard drive write caching is if you are at risk of losing power to the computer unexpectedly. The data that is left in the cache may be lost as a result. For those who are not concerned about such issues, this tip can improve hard drive performance.

Write caching is a feature built into the windows operating system that allows your system to temporary home temporarily hold data before writing it to the disk as you can imagine if you somehow lose power randomly you can actually lose the data that’s being held in the cash so for those who don’t have power settings that are essential or efficient or let’s say reliable then this probably isn’t the best week for you but it is a great one for a lot of people who are already plugged into the system and aren’t worried about data loss of power outages you just right click on computer and you select manage we can bring up your computer management window on the left hand side we are interested in selecting the device manager on the right-hand side you can see your expansion here for your computer I’m running on a virtual machine and then you want to expand your disk drive section and then obviously your hard drive will be displayed here so you want to right click on the drive that you’re optimizing typically it’s the one that has your operating system installed on then you want to select properties and then we’re gonna go to the volumes tab i’m sorry the policies tab and this is where we’re actually going to configure write caching or not and it does have all your warnings and information here to find out if you’re actually in a good situation to enable it for desktop pcs that are plugged in all the time I think write caching is fine i don’t think there’s any worry about enabling it and it may already be enabled if windows has detected you have a desktop pc laptops and can be more concerning because if you randomly lose power or if your battery just dies you can actually put your data at risk of being corrupted and some people say turn off windows write cache buffer flushing on the device will actually give you suck some advantage to for her performance I haven’t really seen a significant amount that actually balances out the risk because of what it will do the what it doesn’t do is a flush out your buffer regularly and this can actually cause major data loss if you enable it so i actually don’t recommend you enable that one leave that one disabled but we’re going to do is we’re going to like I said check this box to enable the right cashing on device select ok and then go ahead and close out the window and you may be prompted for a restart if you’ve made the change to your system and that is it
