Drive Overview

The Seagate ST31000528AS Barracuda is a hard disk drive (HDD) that offers a storage capacity of 1 terabyte (TB). It is designed to operate at 7200 revolutions per minute (RPM) and comes equipped with a 32MB buffer, a Serial Advanced Technology Attachment (SATA) interface, and Native Command Queuing (NCQ) support. In this article, we will take a closer look at each of these features and what they mean for the performance and functionality of the Seagate ST31000528AS Barracuda.

Storage Capacity

The Seagate ST31000528AS Barracuda offers a storage capacity of 1 terabyte (TB). This means that it can store up to 1 trillion bytes of data, which is equivalent to approximately 200,000 songs or 500 hours of high-definition video. With such a large storage capacity, the Seagate ST31000528AS Barracuda is an ideal choice for users who need to store a large amount of data, such as multimedia files, documents, and software applications.

Rotational Speed

The Seagate ST31000528AS Barracuda is designed to operate at 7200 revolutions per minute (RPM). The rotational speed of a hard disk drive refers to the number of times the disk inside the drive spins around per minute. The faster the rotational speed, the faster the drive can read and write data. A 7200 RPM drive is considered to be a standard rotational speed for desktop hard drives and provides a good balance between performance and cost.

Buffer Size

The Seagate ST31000528AS Barracuda comes equipped with a 32MB buffer. The buffer is a small amount of memory that is built into the hard disk drive and is used to temporarily store data that the drive is reading or writing. The larger the buffer size, the more data the drive can store in memory, which can result in faster read and write speeds. A 32MB buffer is considered to be a standard buffer size for desktop hard drives.


The Seagate ST31000528AS Barracuda uses a Serial Advanced Technology Attachment (SATA) interface to connect to a computer. The SATA interface is a popular interface used in modern hard disk drives and provides high-speed data transfer rates. SATA is also hot-swappable, which means that the drive can be removed or inserted into a computer while it is still running.

Low Profile

The Seagate ST31000528AS Barracuda has a low profile, which means that it is thinner than a standard desktop hard disk drive. Specifically, it has a height of 1.0 inch (2.54 cm), whereas a standard desktop hard disk drive has a height of 1.63 inches (4.14 cm). This makes the Seagate ST31000528AS Barracuda ideal for use in slim desktop computers or other systems where space is limited.

Native Command Queuing (NCQ)

The Seagate ST31000528AS Barracuda supports Native Command Queuing (NCQ), which is a feature that can improve the performance of the hard disk drive. NCQ is a technology that allows the hard disk drive to optimize the order in which it reads and writes data to the disk. By doing so, NCQ can reduce the number of seek operations that the hard disk drive needs to perform, which can result in faster read and write speeds.
