    Intel(R) Matrix Storage Event Monitor Service (IAANTmon.exe, IAAnotif.exe)

    Are these actually needed for a laptop running a single HDD? From what I understand is that this is for RAID setup. And if you look on the web for IAANTmon.exe, most of the information you will find is related to Intel Application Accelerator, but this information is outdated for the newer systems, because they use the Intel Matrix Storage Manager, which also uses this process without the Intel Application Accelerator.

    I'm asking this because if you install the Intel driver provided by Lenovo, you will not get this Intel(R) Matrix Storage Event Monitor service installed. But if you install the drivers directly from Intel, it will add this service(IAANTmon.exe) and startup application(IAAnotif.exe) to your Windows.

    I disabled this service and removed the IAAnotif.exe from startup, there is no difference at all, so what's the point of having this? Back then, the Intel installation package directly from Intel, I remembered there is the option for you to not to install this and only install the driver, but the latest 8.2.0.1001 installer doesn't have this option anymore.

    :)

    You're right, it's for RAID setups. I recently found out it isn't necessary otherwise.

    For information, by removing it I no longer have random hang when copying files to external SATA drives.

    Actually, the Intel Matrix Storage Manager does more then just manage RAID devices.

    There are a lot of benefits to having it on your system, even if you aren't running RAID, and only have a single hard drive.

    Back in the day, one of it's primary tasks was managing RAID devices, but these days it does much more, especially on mobile platforms like laptops.

    Such as:
    • Longer battery life: By lowering excessive power usage on the chipset, and ATA/SATA hard drives via Link Power Management (LPM)
    • Enhanced storage performance: Through the Advanced Host Controller Interface (AHCI) which enables a number of advanced features available on hard drives produced today.
    • Enhanced Storage Performance: With Native Command Queuing (NCQ) which allows multiple commands to be sent to a single hard drive at once, managing, and prioritizing those commands for higher efficiency (via the AHCI).

    So although it probably won't hurt your system to disable these features, if your system supports these enhancements ( If your system shipped with them installed, it probably does support them), it's likely in your best interest to keep them enabled.

    Hope somebody finds this helpful ;)
