HDD info for 2010 Dell Inspiron N5110

The Inspiron N5110 supports standard 2.5" SATA drives.  Go to Device Manager and expand Disk drives.  That should list the make and model of the hard drive in your system.

If you are planning to replace/upgrade, take note that it will be more than a simple drive replacement as it will require many components removal to access the motherboard.

Well, finding the specific make of an HDD depends on what was originally shipped with your laptop and what is available in the market for upgrades/replacements.

To check the original make of the HDD, you can either check the service manual, user guide or whatever that came with your device, or if you're comfortable opening up your laptop, you can check the HDD directly. The HDD usually has a label with the manufacturer's name and other details printed on it.

Once you get your HDD details, you can find compatible replacement HDDs (not necessarily the original make) on websites like Etechbuy.

P.S:
Before opening your laptop, ensure you have the necessary tools and a static-safe workspace to prevent damage.
Consider backing up your data before making any hardware modifications.

I hope this helps.
