Built for high-end workstations and multi-media systems, the X300 Pro can support high intensity workloads up to 300TB/yr with increased reliability of up to MTTF 1.0 million hours and room up to 18TB of storage capacity. Optimized to handle high-end graphics and videos, the X300 Pro hard drive delivers a fast 7200 RPM rotational speed and large cache size to help shorten response time. Toshiba’s cache technology helps optimize cache allocation during read/write cycles to help provide high drive performance in real time. Plus, the X300 Pro’s innovative actuator designs help optimize positioning accuracy and read/write performance for quick access to data. [Note]: (1) One Terabyte (1TB) means 10{12] = 1,000,000,000,000 bytes using powers of 10. Actual formatted storage capacity may vary. For details, please visit Toshiba's Consumer HDD website. (2) Compatibility may vary depending on user’s hardware configuration & operating system. (3) Product specifications, colors, configurations and components are subject to change without notice. (4) "2.5-inch" & "3.5-inch" mean the form factor of HDDs. They do not indicate drive's physical size. (5) For "Drive Bays Supported", please contact your Solutions Provider as compatibility with host device will vary based on the system. (6) Workload is a measure of the data throughput of the year, and it is defined as the amount of data written, read or verified by commands from the host system. (7) MTTF (Mean Time to Failure) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may be different from the MTTF. (8) Read and write speed may vary depending on the host device, read and write conditions, and file size. (9) Drive life may vary depending on usage and workload. (10) Standard limited warranty terms apply. The warranty brochure can be viewed at Toshiba's Consumer HDD website.
