Understanding the Seagate Stgx4000400 Hard Drive
The Seagate Stgx4000400 is a specific part number designation for a particular model of Seagate hard drives. Before buying, I made sure to verify the exact specifications and compatibility of this model with my system. It’s important to note that part numbers can sometimes be confusing as they may correspond to OEM or specialized versions of drives.
Key Features I Looked For
- Capacity: The model number suggests a 400GB capacity, which was suitable for my storage needs without being excessive. I recommend assessing your storage requirements before choosing this drive.
- Form Factor: I confirmed that it is a 3.5-inch drive, which fits desktop PCs and certain NAS devices. If you need a laptop or portable drive, this might not be the right choice.
- Interface: This hard drive uses the SATA interface, offering good compatibility with most modern motherboards. I made sure my system supported SATA connections.
- RPM and Performance: While the exact RPM may vary, many Seagate drives with this part number run at 7200 RPM, providing a good balance of speed and reliability for everyday computing tasks.
Compatibility Considerations
One of the first things I checked was whether the Seagate Stgx4000400 would work with my existing hardware. Since it’s a SATA drive, it’s compatible with most desktops and many NAS devices. However, if you have a system that requires SAS or PCIe drives, this won’t be suitable. Also, ensure your BIOS and operating system support the drive capacity.
Reliability and Warranty

I recommend verifying the warranty length with the seller. Additionally, checking user reviews and failure rates can give you peace of mind about the drive’s durability.
Price and Value
When I compared prices, this model was competitively priced for a 400GB SATA drive. However, depending on your budget and storage needs, you might want to consider newer models with higher capacity or SSDs for faster performance. I balanced cost against my performance needs and decided this drive was a good fit.
Installation Tips from My Experience
Installing the Seagate Stgx4000400 was straightforward. Here are a few tips based on what I learned:
- Handle the drive carefully to avoid static damage.
- Use the correct screws and mount it securely in your PC case or NAS bay.

- Format the drive properly in your operating system before use.
