About Hardware Hitachi HTS722016K9SA00
The Hitachi HTS722016K9SA00 is a thick design 2.5-inch hard disk with a capacity of 160GB, designed for laptops and other portable devices. Unlike most laptop HDDs that use a rotation speed of 5400 RPM, this model offers a speed of 7200 RPM, providing a significant improvement in read/write performance, especially in computing tasks that require fast data access.
Equipped with 16MB of buffer cache, this HDD is capable of handling heavier workloads, such as multitasking, application installation, or activities with high I/O intensity. This speed gives it an edge over regular HDDs in terms of response time and efficiency when running an operating system or opening large files. Although its capacity is relatively small when compared to today's storage standards, the HTS722016K9SA00 is still very suitable for use as additional storage or to revive older systems that still rely on 2.5” SATA storage.
The test was conducted using an HP 1000 1b05AU laptop with the following configuration: AMD E1-1200 CPU, 4GB DDR3 RAM (2x2GB in single-channel mode due to CPU limitations), and Windows 7 64-bit operating system. The HDD was installed via an HDD Caddy in place of an optical drive, demonstrating the flexibility of using it as a second storage in a system with an additional SATA slot.
During testing, the drive's performance showed fast response when booting the operating system, opening heavy applications, and performing large file transfers. Despite its limited capacity, the 7200 RPM speed and larger cache compared to 5400 RPM HDDs make it an ideal choice for users who prioritize access speed over large capacity.
The Hitachi HTS722016K9SA00 is still an attractive option for users who want fast yet affordable storage, especially in legacy system configurations or as a secondary drive for modern systems with specific needs.
Tested on:
Device: HP 1000 1b05au (using HDD Enclosure)
Specs:
CPU: AMD E1-1200
OS: Windows 7
RAM: 2x2GB (Does not support dual channel due to limitations of the CPU, currently running single channel mode)
* For CrystalDiskMark the hard drive is directly run on the main sata port, and the hard drive is used as the operating system.
