Performance Hard Drive

Responds in an instant

The X300’s dual-stage actuator design improves positional accuracy, negating the effects on head-track alignment that vibrations can cause. This design makes for more precise, faster read and write speeds for instant access to your data.

Accurate tracking

Vibration is one big enemy of reliable HDD operation. Toshiba’s innovative Stable Platter Technology minimizes vibrations by stabilizing the motor shaft at both ends. And that means improved tracking accuracy and maximum performance during read and write operations.

Keep data secure

The X300’s design includes an internal shock sensor, ensuring no data is lost. In addition, ramp loading technology means that when the hard drive or desktop PC are being transported, the drive slider does not make contact with the disk, minimising the risk of wear or data loss.

Reduced noise and energy costs

The 12 TB and 14 TB X300 Performance Hard Drives use a helium-sealed design, achieving low power consumption while increasing storage density. Toshiba Group’s laser welding technology ensures that the helium remains securely sealed inside the drive enclosure. With the environment in mind, the helium-filled X300 models minimize acoustic output to just 20db (typical) in idle mode. The devices are ideal for large scale server systems allowing for rich scalability of up to 8 drives.

Built to deliver, designed to last

Toshiba is renowned the world over for 50 years of leading innovation – and the power behind its range of hard drives is no exception. Designed for high capacity and excellent performance, you can be sure that Toshiba’s wealth of experience in hard drives is at work in your storage system.
