Description
More Specification
The 0F27354 Hitachi Ultrastar 10TB 7.2K RPM SAS 12GBPS 256MB Hard Drive is a high-performance, enterprise-grade hard drive that is designed for use in data centers and other mission-critical environments.
This hard drive has a capacity of 10 terabytes (TB), which is a large amount of storage space that can be used to store a large amount of data such as videos, images, and documents. It’s built with SAS interface, which is a type of high-speed data transfer interface that is commonly used in enterprise environments. The SAS interface supports data transfer rates of up to 12 Gbps, which is faster than other hard drive with lower transfer rate.
It also features a 7.2K RPM rotation speed which is considered to be a standard speed for enterprise-grade hard drives and allows for fast data access. The hard drive also has a large 256MB cache, which is designed to store frequently accessed data, which can improve its performance. Additionally, it has a buffer memory to smooth out the data transfer process.
The hard drive is designed to be highly reliable and durable, with features such as Advanced Format (AF) sector technology and a robust mechanical design that is built to withstand the rigors of 24/7 operation.
Cache and Buffer
Cache and buffer refer to the temporary storage space used by a hard drive to improve its performance.
Cache is a small amount of high-speed memory that is used to store recently accessed data. When the hard drive receives a request for data, it first checks the cache to see if the data is already stored there. If it is, the hard drive can quickly retrieve the data from the cache, rather than having to access the slower platters. This can greatly improve the hard drive’s performance, especially for frequently accessed data.
The 0F27354 Hitachi Ultrastar 10TB 7.2K RPM SAS 12GBPS 256MB Hard Drive has a cache of 256MB, which is a relatively large amount of cache for a hard drive. This allows the hard drive to store more frequently accessed data in the cache, which can improve its performance.
A buffer, also known as a buffer memory, is a small amount of memory that is used to store data that is being transferred to or from the hard drive. The buffer acts as a temporary holding area for the data, and can help to smooth out the data transfer process.
The buffer size is usually measured in bytes, for example, 32MB or 64MB. The larger the buffer, the more data can be stored there, and the smoother the data transfer process will be. A larger buffer can also help to improve the hard drive’s performance in cases where the data transfer rate is not consistent.
SAS interface and Data Transfer rate
The SAS (Serial Attached SCSI) interface is a high-speed data transfer interface that is commonly used in enterprise environments. It is a point-to-point interface, which means that each device is connected directly to the host, rather than sharing a common bus. This allows for faster data transfer speeds and improved scalability.
The 0F27354 Hitachi Ultrastar 10TB 7.2K RPM SAS 12GBPS 256MB Hard Drive uses SAS interface, which supports data transfer rates of up to 12 Gbps. This means that the hard drive can transfer data to and from the host at a faster rate than other hard drives with lower transfer rates. This is beneficial for applications that require fast data access and high throughput, such as databases, virtualization, and big data analytics.
The SAS interface also includes features such as improved scalability, longer cable lengths, and greater reliability than other interfaces. This makes it an ideal choice for use in enterprise environments where high performance and reliability are critical.
