What Can You Store on
2TB gives you meaningful, everyday storage capacity. Here's a practical guide:
- Windows 11 installation (~20GB) + all system updates and apps
- Approx. 512K+ photos (at 4MB average smartphone quality)
- Around 1024 hours of Full HD (1080p) video footage
- Approximately 409600 songs in MP3 format
- 80+ typical PC games alongside your operating system
Why Choose an HDD for Bulk Storage?
For large-capacity secondary storage, HDDs remain the most cost-effective option. While SSDs are faster for your operating system and frequently accessed files, an HDD delivers far more gigabytes per pound for archives, media libraries, and cold storage. The ideal setup for most desktop users is an SSD for Windows, paired with this HDD for bulk files.
Use this drive as a secondary storage drive alongside an SSD as your primary OS drive. Your system will boot fast from the SSD while the HDD handles your large file storage at a much lower cost per GB. See our SSD range for compatible primary drives.
