Introduction to the Seagate ST3750640NS Hard Drive

In today's digital era, data storage is a crucial aspect of any technological setup. Be it a personal computer, a server, or a data center, hard disk drives (HDD) have become an essential component in storing and accessing data. Seagate Technology is one of the most prominent manufacturers of HDDs, and in this article, we will take a detailed look at the Seagate ST3750640NS Barracuda HDD, which has a capacity of 750GB, 7200 revolutions per minute (RPM), and uses the Serial Advanced Technology Attachment (SATA) interface.

Capacity of 750GB Hard Disk Drive

The Seagate ST3750640NS Barracuda HDD has a capacity of 750GB or 750 gigabytes, which means it can store up to 750 billion bytes of data. This capacity is suitable for storing large amounts of data, such as documents, photos, videos, and audio files. In terms of video, this capacity is capable of storing up to 187,500 minutes of standard definition video, or 25,000 minutes of high-definition video, assuming an average file size of 4GB.

Speed of ATA 16MB Hard Drive

The HDD's speed is measured in revolutions per minute (RPM), and the Seagate ST3750640NS Barracuda HDD has a speed of 7200 RPM. This means that the hard drive platters spin 7200 times per minute, allowing for faster read and write speeds compared to slower RPM drives. This speed is particularly important for accessing and transferring large files and data-intensive applications, as it allows for quick and seamless performance.

Interface & Buffer

The Seagate ST3750640NS Barracuda HDD uses the Serial Advanced Technology Attachment (SATA) interface, which is a popular interface used in modern hard drives. SATA interfaces come in different speeds, and the version used in this HDD is SATA II, which has a data transfer rate of up to 3 Gbps (gigabits per second). This interface allows for quick and reliable data transfer between the HDD and the computer's motherboard, providing faster read and write speeds compared to older interfaces like Parallel ATA (PATA)

The HDD's buffer, also known as the cache, is a temporary storage area for data that the hard drive is currently accessing. The Seagate ST3750640NS Barracuda HDD has a buffer size of 16MB, which means it can temporarily store up to 16 megabytes of data. A larger buffer size allows for smoother performance when accessing frequently used data, as the hard drive can retrieve the data from the cache instead of having to search for it on the physical disk. This improves the overall performance of the HDD.

Form Factor

The Seagate ST3750640NS Barracuda HDD has a form factor of 3.5 inches, which is a standard size for desktop computer hard drives. This form factor makes it easy to install the HDD in a desktop computer, as it is compatible with most computer cases and drive bays. Additionally, the 3.5-inch form factor allows for larger storage capacities compared to smaller form factors like 2.5 inches, making it an ideal choice for those who need a high-capacity storage solution.


Reliability is an important factor to consider when choosing a hard drive, and the Seagate ST3750640NS Barracuda HDD is known for its reliability. It has a Mean Time Between Failures (MTBF) of 1.2 million hours, which means that it is expected to last for a long time under normal usage conditions. Additionally, it comes with Seagate's SeaTools diagnostic software, which can help diagnose and troubleshoot any issues with the hard drive.
