ST3250820AS Seagate Barracuda 250GB 7.2K RPM 8MB Buffer Form Factor SATA300 Hard Drive | Refurbished

The Seagate ST3250820AV is a hard disk drive designed for use in personal computers and other electronic devices. It has a capacity of 250GB, which means it can store a large amount of data, including operating systems, software, and media files. In this article, we will take a closer look at the features and specifications of this hard drive.

Capacity and Speed

As mentioned earlier, the Seagate ST3250820AV has a storage capacity of 250GB. This means it can store up to 250 billion bytes of data. To put this into perspective, a standard DVD can hold up to 4.7GB of data, which means this hard drive can store the equivalent of 53 DVDs.

In terms of speed, the Seagate ST3250820AV has a rotation speed of 7,200 revolutions per minute (RPM). This means that the disk inside the hard drive spins at a rate of 7,200 times per minute. The faster the disk spins, the faster the hard drive can access data, which results in quicker read and write times.

Buffer Size

The Seagate ST3250820AV has a buffer size of 8MB. The buffer, also known as cache, is a small amount of memory located on the hard drive itself. This memory is used to temporarily store data that is frequently accessed, allowing for faster access times. The larger the buffer size, the more data that can be stored, and the faster the hard drive can access frequently used data.

ATA Interface

The Seagate ST3250820AV uses an ATA interface, which stands for Advanced Technology Attachment. This interface is used to connect the hard drive to the motherboard of a computer or other electronic device. The ATA interface has been around since the early days of personal computers, and it is still used in many devices today.

The ATA interface used by the Seagate ST3250820AV is the Parallel ATA (PATA) interface. This interface uses a 40-pin connector to connect to the motherboard. It also uses a ribbon cable to connect to the motherboard, which can limit the airflow in a computer case, potentially causing overheating. However, this interface is still used today in some devices due to its simplicity and compatibility with older systems.

Ultra ATA

The Seagate ST3250820AV also supports Ultra ATA, also known as Ultra DMA. This is a technology that was introduced in the mid-1990s to increase the data transfer rate of hard drives. Ultra ATA supports data transfer rates of up to 133 megabytes per second (MB/s), which is significantly faster than the original ATA interface.

Compatibility

The Seagate ST3250820AV is compatible with a wide range of operating systems, including Windows, Mac, and Linux. It is also compatible with a variety of personal computers and electronic devices. However, it is important to ensure that the device you plan to use this hard drive in has an ATA interface and supports a 250GB hard drive.

In summary, the Seagate ST3250820AV is a hard disk drive designed for use in personal computers and other electronic devices. It has a storage capacity of 250GB, a rotation speed of 7,200 RPM, and a buffer size of 8MB. It uses an ATA interface and supports Ultra ATA technology for faster data transfer rates. It is compatible with a variety of operating systems and devices, making it a versatile choice for those in need of additional storage space.
