Overview of the Seagate ST3300655SS Internal Hard Drive

The Seagate ST3300655SS Cheetah is a high-performance hard disk drive (HDD) with a capacity of 300GB. It operates at 15000 revolutions per minute (RPM), making it one of the fastest HDDs available in the market. The drive uses Serial Attached SCSI (SAS) technology and has a Gigabits per second (6GBPS) data transfer rate, which means it can quickly transfer large files and data.

Form Factor

The Seagate ST3300655SS Cheetah hard disk drive has a 3.5-inch form factor, which is the standard size for desktop computers. It measures 4 inches in width, 5.75 inches in length, and 1 inch in height. The form factor determines the physical size of the hard drive and the type of computer it can be used with.

Buffer Size

The buffer size of the Seagate ST3300655SS Cheetah is 16MB. The buffer is also known as cache, and it is a small amount of fast memory on the hard disk drive. It is used to temporarily store data that the hard drive frequently accesses, which helps to improve its overall performance. The larger the buffer size, the more data the hard drive can store in cache, and the faster it can access frequently used data.


The Seagate ST3300655SS Cheetah uses Serial Attached SCSI (SAS) technology, which is a high-speed interface used for connecting hard drives and other storage devices to a computer. SAS is a successor to the older parallel SCSI interface and offers faster data transfer rates, greater reliability, and better scalability. The interface also supports longer cable lengths, which makes it ideal for use in large-scale storage systems.


The Seagate ST3300655SS Cheetah hard disk drive has a capacity of 300GB, which is a measure of how much data it can store. The capacity of a hard drive is determined by the number of magnetic platters it has and the density of data that can be written to them. The 300GB capacity of the Seagate ST3300655SS Cheetah makes it suitable for use in high-performance computing environments that require large amounts of data storage.

Rotational Speed

The Seagate ST3300655SS Cheetah has a rotational speed of 15000 revolutions per minute (RPM). This means that the platters inside the hard drive spin at a speed of 15000 RPM, which allows for faster data access and transfer rates. A higher RPM generally means better performance, but it also results in more noise and heat production.

Data Transfer Rate

The Seagate ST3300655SS Cheetah has a Gigabits per second (6GBPS) data transfer rate. This refers to the speed at which data can be transferred between the hard drive and the computer. The 6GBPS transfer rate of the Seagate ST3300655SS Cheetah is one of the fastest available in the market and makes it ideal for use in high-performance computing environments that require quick data access and transfer.


The Seagate ST3300655SS Cheetah hard disk drive is an internal drive, which means it is designed to be installed inside a computer or server. Internal drives are usually faster and more reliable than external drives, which are designed to be portable and can be connected to a computer via USB or other interfaces.
