Toshiba X300 Performance 3.5" Internal Hard Drive

Extreme Performance. Massive Capacity.

The Toshiba X300 Performance Internal Hard Drive is designed to deliver high performance and capacity that gamers and creative professionals demand. The X300 offers 7200 RPM and large cache size to keep your gaming experience going in real-time.

The X300 provides massive storage capacity up to 14TB to grow with your gaming libraries and HD content. Plus, this drive comes with data protection technologies to help keep your data safe. It’s all backed by over 45 years of storage expertise and exceptional quality of Toshiba, the name you can trust.

Designed for Gamers & Content Creators

Whether you’re a PC gamer, video editor, photographer, or graphic designer, the X300 offers the capacity and performance that the pro demands.

The X300 provides up to 14TB of capacity to store all your growing game libraries and HD content – so you can keep all your creations and game achievements without worrying about running out of space.

Powerful Performance

Since the last thing gamers and production artists want is lag, the X300 delivers 7200 RPM and up to 256 MB cache size for a responsive experience when loading games or large multimedia files. Plus, Toshiba’s cache technology helps optimize cache allocation during read/write cycles to provide high performance in real time.

Data Protection

The X300’s internal shock sensor and ramp-loading technology help protect your drive and data from harm, while drive stabilization technology helps mitigate vibrations and improve tracking accuracy - so you can play, edit, animate and create as much as you like, without worrying about the safety of your content.

Helium-Sealed Design

The 12TB and 14TB models utilize a Helium-Sealed design to deliver increased storage density and lower operating power profile*. This helps maximize the storage capacity and improve the power efficiency of your gaming system*.

The helium-filled X300 models run more efficiently than a standard air-filled model, delivering a smoother drive performance for a responsive game play. The helium models reduce acoustic output (in idle mode) by up to 40%* and operating power consumption by up to 30%*.

* compared to the X300 10TB model.
