Note: Switching from IDE/RAID to AHCI may prevent Windows from booting unless registry/driver settings are adjusted before changing BIOS. Use Microsoft’s documented procedure (enable storahci start override or install Intel driver first).
Acer rarely updates N20C5-specific drivers after 12–18 months. However, you can safely upgrade to newer Intel RST drivers from Intel’s website (version 19.x and 20.x have been tested on N20C5 boards without issues).
Recommended update schedule:
The Acer N20C5 (also sold under similar model names) uses storage controllers common to Intel-based notebooks from the mid-2010s. Installing the correct storage driver ensures maximum performance and stability for SATA/AHCI or NVMe devices. This guide covers how to identify the controller, choose the right driver, and install or troubleshoot it. acer n20c5 storage driver
The N20C5 requires kernel parameter modprobe.blacklist=ideapad_laptop or nvme_core.default_ps_max_latency_us=0. For Ubuntu/Debian, install the intel-vmd driver:
sudo apt update && sudo apt install vmd
sudo update-initramfs -u
Before jumping into downloads, let’s clarify the terminology. A “storage driver” in the context of the Acer N20C5 motherboard refers to software that allows your operating system (Windows 10, Windows 11, or Linux) to communicate with your computer’s storage controller.
The N20C5 board typically uses one of two modern storage interfaces: Reboot
Without the correct driver, Windows may not detect your SSD or HDD during installation, or the system may crash on boot. The N20C5-specific driver is often bundled within chipset drivers but is also distributed separately as an F6 driver (for pre-installation environment).
Even with the correct Acer N20C5 storage driver, problems can arise. Here are solutions to the most frequent issues:
The Acer N20C5 does not have a unique "secret" driver; it uses the standard Intel RST VMD 18.x or 19.x series driver. Note: Switching from IDE/RAID to AHCI may prevent
Pro Tip: If you are building a deployment USB for multiple Acer devices, use a tool like Rufus to create your Windows USB. Rufus has an option to "Disable BitLocker auto-device encryption" and "Disable VMD," which bypasses this issue entirely.
Don't throw your laptop away because the SSD "disappeared." You just needed the right chipset driver. Install that F6 driver, and your N20C5 will roar back to life.

As a last resort (if Acer is slow to update), you can use Intel’s generic IRST driver. Download from Intel’s Download Center and look for “Intel Rapid Storage Technology (IRST) Driver for Windows 10/11”. However, the Acer-tuned version is always preferable because it includes custom power management settings for your specific N20C5 hardware.
