About Hardware Seagate Momentus ST950032-5AS
The Seagate ST9500325AS is a 500GB hard disk drive (HDD) with a 2.5-inch form factor, designed specifically for laptops, notebooks and portable devices. Utilizing a SATA II interface (3.0 Gbps) and a rotation speed of 5400 RPM, this hard drive offers a combination of low power consumption and sufficient performance for everyday computing needs, such as document storage, media, and light operating system installations.
Equipped with 8MB of buffer cache, the Seagate ST9500325AS is capable of handling basic read/write activities steadily, though not as fast as modern solid-state drives (SSDs). Nevertheless, it remains a popular choice for budget-conscious systems, secondary data storage, or upgrading storage capacity without high costs. Compared to 7200 RPM HDDs, 5400 RPM models like these also generate less heat and noise, making them suitable for laptops that prioritize comfort and power efficiency.
Technically, this HDD has an average seek time of about 12ms and is designed to support daily workloads with a high level of reliability. In our data transfer speed benchmark tests, the Seagate ST9500325AS performed as follows:
- Read Speed (Sequential Read): ~58 MB/s
- Write Speed (Sequential Write): ~62 MB/s
While its performance is far below that of SSDs, it is still relevant for basic use, especially on older systems or when large capacity is more important than speed. The Seagate ST9500325AS is also commonly found as built-in storage on previous generation laptops, and is still widely used for backups, large media file storage, and as a portable storage solution with external enclosures.
