Caching is an extremely intimidating word to anyone who has even looked at a computer before. It sounds like your computer is hanging on to some cash for you, which, as a computer, it doesn’t really make any sense. Caching isn’t a complicated topic though, in the computer world, all it really means is “temporarily storing” data so it can quickly have access to it later if it needs it. We “cache” things when we think they will reloaded often so we don’t have to go through the whole process of loading them over and over again.
In this video, you will learn how to enable write caching on the primary hard drive of your computer. Write caching stores data that needs to be written in your hard drive in a “holding pattern” while your hard drive writes it. This allows your computer to perform other system tasks before something has been “successfully” written to your hard drive. Now this description should make you a bit nervous, because as you know, if the data isn’t stored in your hard drive – isn’t there a risk of losing it? That’s where the inherent risk of write caching comes into play.
You see, if your data is in a “holding pattern” in system memory and it hasn’t been written to the hard drive and there is suddenly a power outage, then the memory is cleared and your data is not properly stored. This is why it is not recommended to enable write caching on the primary hard drive if you believe there may be sudden power outages causing your equipment to lose power. If you are comfortable with this added risk, then enabling write caching on the primary hard drive is a great way to get more disk performance out of your computer.
Enable Write Caching on the Primary Hard Drive
1. Go to your desktop.
2. Right click on ‘computer‘
3. Select ‘properties’
4. Under Control Panel Home, select ‘Device Manager’
5. Select the ‘drop down arrow’ next to the category of ‘disk drives’
6. Right click on the disk drive that is your primary hard drive
7. Select ‘properties’
8. Select ‘policies’
9. Check the box ‘Enable Write Caching on the Device’
10. Also check the box ‘turn off windows write-cache buffer flushing on the device’
11. Select ‘Ok’
That’s it! Now remember, you can’t blame any data loss on me, I did warn you and explain to you what can happen in the instance of a sudden power loss. If you are uncomfortable with this in any way I don’t recommend going through adding this feature. Also, as a side note, do not enable write caching on removable devices such as external flash drives or usb drives, you will risk data corruption if someone bumps the cable or unplugs it too early.
