Intel SSD 520 Series unresponsive in Windows 10

[CLin77]

I recently upgraded my Lenovo ThinkPad T61p (Type 6457-BF5) with an Intel SSD 520 Series (180 GB), and installed Windows 10 Professional 64-bit (Build 16299) on it. The SSD provided great performance improvement, but I also noticed something strange - the system would freeze every a few minutes, with no or light access to the SSD. During the incident, the laptop's HDD indicator was constantly on for up to a minute, and the mouse cursor could sometimes be moved, but clicking on objects was unresponsive.

I searched online and found a relevant article entitled "Task Manager might show 100% disk utilization on Windows 10 devices with Message Signaled Interrupt (MSI) mode enabled" on Microsoft Windows 10 Support (https://support.microsoft.com/en-us/help/3083595/task-manager-might-show-100-disk-utilization-on-win... https://support.microsoft.com/en-us/help/3083595/task-manager-might-show-100-disk-utilization-on-win...). The described symptoms seemed exactly the same as mine, so I followed the instructions to disable the MSI mode in the registry, and rebooted my laptop.

However, the problem persisted. I installed the Intel SSD Toolbox and my SSD is in perfect condition, with the firmware version of LE1i. I guess it might need a more suitable driver than the default one provided by Windows 10, but I did not find it on Intel's website. There might also be some other settings needing tweaking. Could you please advise how to resolve this problem? Many thanks in advance.

My SSD 520's firmware is 400i but I find that it's an oem product through ISN. Which one is wrong？

Hi Snoopy123,

Based on your Firmware version 400i, we would like to inform you that the SSD is a retail version as per https://www.intel.com/content/www/us/en/support/articles/000017245/memory-and-storage.html this article. The reason why the https://supporttickets.intel.com/warrantyinfo Warranty Website shows the OEM information is because your drive was in a box that usually is assigned to OEMs. You can check the information https://ark.intel.com/products/66247/Intel-SSD-520-Series-60GB-2_5in-SATA-6Gbs-25nm-MLC here, you just need to click the "Ordering and Compliance" tab and you will be able to see the information. Please let us know if there is something else we can assist you with. Regards, Junior M.
