Product Information to Seagate ST9500423AS Hard Disk Drive

Seagate ST9500423AS is a 2.5-inch internal hard disk drive designed for use in laptops and other portable devices. The hard drive has a storage capacity of 500 gigabytes (GB), a spindle speed of 7200 revolutions per minute (RPM), and a cache size of 16 megabytes (MB). The interface used by the hard drive is Serial Advanced Technology Attachment (SATA)-II, which provides a high-speed data transfer rate of up to 3 gigabits per second (Gbps).

Storage Capacity

The Seagate ST9500423AS hard drive has a storage capacity of 500 gigabytes (GB). This means it can store up to 500 billion bytes of data, which is equivalent to approximately 100,000 songs, 150 high-definition movies, or 250,000 high-resolution photos. This makes the hard drive suitable for use in laptops and other portable devices that require high-capacity storage.

Spindle Speed

The spindle speed of the Seagate ST9500423AS hard drive is 7200 revolutions per minute (RPM). This refers to the speed at which the hard drive's platters spin around their axis. A faster spindle speed means that the hard drive can read and write data more quickly, resulting in faster access times and improved overall performance. A spindle speed of 7200 RPM is considered to be fast and suitable for high-performance computing tasks such as gaming, video editing, and 3D rendering.

Cache Size

The cache size of the Seagate ST9500423AS hard drive is 16 megabytes (MB). This refers to the amount of fast-access memory that the hard drive uses to temporarily store frequently accessed data. A larger cache size can improve overall performance by reducing the time it takes for the hard drive to retrieve data from the platters. A cache size of 16 MB is considered to be adequate for most computing tasks.


The Seagate ST9500423AS hard drive uses the Serial Advanced Technology Attachment (SATA)-II interface. SATA is a standard interface used to connect storage devices such as hard drives and solid-state drives to a computer's motherboard. SATA-II provides a data transfer rate of up to 3 gigabits per second (Gbps), which is faster than the previous SATA-I standard. The faster data transfer rate of SATA-II allows for faster data access times and improved overall performance.

Form Factor

The Seagate ST9500423AS hard drive has a form factor of 2.5 inches. This refers to the physical size of the hard drive, which is suitable for use in laptops and other portable devices. A 2.5-inch hard drive is smaller and more compact than a 3.5-inch hard drive, which is typically used in desktop computers.

Internal vs. External Hard Drives

Internal hard drives, like the Seagate ST9500423AS, are designed to be installed inside a computer or other device. They are typically used as the primary storage device for the operating system, applications, and data files. Internal hard drives are usually faster and more reliable than external hard drives because they are not subject to the wear and tear of being moved around or bumped.

External hard drives, on the other hand, are designed to be portable and are often used for backup and storage purposes. They are typically connected to a computer or other device via a USB or Thunderbolt port. External hard drives can be either HDD (hard disk drive) or SSD (solid-state drive) and have a wide range of storage capacities.
