Hitachi 200GB 7200 RPM 2.5-inch hard drive E7K200 is the industry's only third-generation 7200 RPM 2.5-inch hard drive with enhanced availability. Compared to previous products, Hitachi™ E7K200 has doubled its capacity and improved its performance by 22%. With a capacity of 200GB, it is the best 7200 RPM 2.5-inch hard drive product, and its performance is far ahead in PCMark tests. In addition to its higher rotation speed, E7K200 also has the same low power consumption, low heat generation and quietness as 5400 RPM hard drives, which helps system manufacturers reduce power consumption without sacrificing performance. In addition, Hitachi E7K200 has higher shock resistance, and its design fully meets the requirements of rugged and reliable storage in non-stop running environments.
The Hitachi E7K200 is a 2.5‑inch, 7200 RPM mobile hard disk designed for 24 × 7 operation. It offers capacities of 200 GB, 160 GB or 120 GB, a 16 MB cache, and high data transfer rates up to 876 Mb/s while maintaining low power consumption and noise comparable to 5400 RPM drives.
The datasheet lists detailed mechanical, electrical and environmental specifications, including dimensions (70 × 100 mm, 115 g), operating temperature range (5 °C – 40 °C), shock resistance (350 G operating, 1000 G non‑operating), and power usage for various modes. Support contacts for North America, APAC and EMEA are also provided. This manual is written in Chinese.
