Description
Form Factor
The form factor of the Hitachi Ultrastar DC HC320 8TB hard drive is 3.5 inches. The form factor of a hard drive refers to its physical size and shape. A 3.5-inch form factor means that the hard drive is designed to fit in a standard 3.5-inch drive bay in a computer.
This is the most common form factor for internal hard drives, and is typically used in desktop computers, servers and storage devices.
It should be noted that 3.5 inch hard drives are larger than their 2.5 inch counterparts that are commonly used in laptops and other portable devices, which means they take up more space.
256MB Cache HDD
The 256MB cache on the Hitachi Ultrastar DC HC320 8TB hard drive refers to the amount of memory that is built into the drive to temporarily store frequently accessed data. This cache is used to improve the overall performance of the hard drive by allowing it to quickly access and transfer the most frequently used data without having to constantly access the slower mechanical parts of the drive.
The larger the cache size, the more data the drive can store and access quickly, which can result in faster performance. In the case of the Hitachi Ultrastar DC HC320 8TB, the 256MB cache is a large buffer that can help to improve the drive’s performance when reading and writing large amounts of data.
Data Transfer Speeds
The data transfer speed of the Hitachi Ultrastar DC HC320 8TB hard drive is 12 Gbps SAS. SAS (Serial Attached SCSI) is a high-speed data transfer interface that provides faster data transfer rates than traditional SATA interfaces.
SAS 12 Gbps is the latest and fastest version of the SAS interface, which can transfer data at speeds of up to 12 Gbps. This means that data can be read from and written to the drive at very high speeds, making it suitable for use in high-performance applications such as data centers, enterprise storage systems, and other demanding environments where fast data access and transfer is critical.
Additionally, the drive also spins at 7.2K RPM (Rotation Per Minute) which is the speed of the mechanical part of the drive that stores the data, spinning the platter at 7200 revolutions per minute, allowing faster access to the data stored in it.
