Enable Write cache on SATA hard drive


There are many ways to optimise your hard drive: defragment regularly, deep clean or set the different hard drives by activating the write cache. In the end, you will get better performance and this, with just a few clicks of mouse! Good reading!

Start by opening the start Menu then enter Device Manager. You can also access it via the Control Panel.

Once opened, unfold Disk drives. This is where you should recognise the name of your hard drive. In this example, it is a Hitachi.

Double-click on it and open the tab Strategies.

All you have to do is tick Enable Writing Cache on Disk.

If you want to go further, you can also check Enable advanced performance.

However, this means that you have a backup power supply (battery for a laptop or an inverter for a PC) in case a power outage occurs and which would result in data loss.

It may also be unavailable in case of material limitation. Indeed, such an option can cause system instabilities like BSOD (Blue Screen Of the Death) that I have personally seen. That said, an isolated case should not be generalised. I invite you to try it and disable it in case of problems.

In short, a 2-level tip: one without known risks and the second to be used with caution.

Anyway, the performance will be at the rendezvous after activation of the write cache!

    Thanks for combining it, but Surprise! When I executed for the cache in writing, the latter was already done.

    Wouldn't it be by default in Vista? (between us I have to recognise that my version of Vista Ultimate SP1 is not the most Catholic... if you see what I mean)

  • @Lion77: yes, a lot of original configurations have this option enabled by default. However, the second option is generally disabled although it deserves to be known. But, it can actually come from your Vista...

    Lol, ptite question purely informative (and therefore not Protestant therefore no problem of secularism...) for what is the concrete purpose of these two options? What are the effects on SD?

  • Milous

    Yeah, but technically what’s going on? What’s it like to activate the cache? Does that increase the transfer frequency? I don't know.

  • The disk cache is a space of the RAM that interposes between the system and the hard disk to speed up the reading and writing of the data.

    Disk cache is a way to reduce the time to access a file on the disk. If you open a file, the file will be saved in the disk cache, so it will be uploaded faster if you open it another time.

  • Yeah, that’s something like that. What’s funny is that you can also increase your RAM with virtual memory, which basically consists of using your hard drive to simulate RAM, so if you pair the two systems you have disk memory simulated by even simulated RAM not disk memory
    Microsoft has its reasons that sometimes (often) the reason ignores;-p

  • @Wolforg : thank you for replying to Milous !

    @Milous : I did not understand the question from that point of fact. But thanks to the growing community spirit on this blog, a loyal reader has given you an answer.

    As one who speaks English and is viewing this page as translated by Google, I am utterly baffeled over the inclusion of concepts such as “secular”,“Catholic” & “Buddhist” in a computer help column. Maybe a bilingual person could explain where religion and Windows intersect? But is just stupidity on the part of Google?

    I tried this setting... in vain...
    Under the check mark is indicated: This driver cannot change its write cache setting.
    Test of the driver’s MAJ, without further success...
    Disc HITACHI SATA HTS542525K9SA00
    BIOS checked and SATA in AHCI.

  • @Domduple : if this setting is not allowed, it is simply that your hard drive does not support it. So you should not try to override security or damage your equipment.

    Good morning, Maigret,
    after continuing to browse this excellent blog, I think I found the answer...
    The driver is inhibited by the Intel Matrix Storage concept that takes control. The interface — rather spartiate — confirms the SATA management as activated.
    Thank you again.

    Good morning,
    The Western Digital 1.0 TB internal hard drive device no longer allows the change of its write cache parameter.
    How can I change the cache settings in writing?
    This disk was the main system disk of the computer with its logs.
    He became “unknown”!. More accesses, more software, including my pro Autocad Architecture software, under windows pro.
    I don't even even initialise it.
