Performance That Meets Demands Toshiba’s 3.5-inch P300 Desktop PC Hard Drive delivers a high performance for professionals. With its dual-stage actuator, you can count on smooth, responsive computing. What’s more, your data and media is secured with a ramp loading design, as well as a shock sensor. Performance Alongside Reliability The P300’s dual-stage actuator, available in the 2 TB to 6 TB models, 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, and instant access to your data. Enhanced Access Performance The data read/write access sequence performance is further enhanced through innovative techniques to minimize head movement and disk revolutions. Optimized data access sequence helps improve performance and minimize mechanical workload from the drive. Keep Data Secure The P300’s design includes an internal shock sensor, ensuring no data is lost. In addition, ramp loading technology means that when your hard drive or desktop PC are being transported, the drive slider does not make contact with the disk and risk wearing or data loss.
