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.

The Serial Attached SCSI (SAS) hard drives have become increasingly popular for their increasing use in high-end workstations and servers. These drives are employed in consumer desktops and modern servers for their speed and reliability. Enterprises have made the SAS hard drives their de-facto standard. Now, the 12Gbps speed throws the usefulness of these drives up a notch.
Most professional hosting providers now use SAS 12Gbps hard drives for data production. These drives have proven useful in high input/output operations and critical website functions. Users trust these drives because there is no risk of data loss, corruption, or downtime.
SAS 12Gbps drives read, write, and process data within split seconds. The latest 12Gbps disks use the latest RAID hardware technology to offer faster data transfer and recovery rates. They are perfect for sequential data, high workloads, and random IOPS alike.
This function allows them to be best suited for servers that have 100 percent duty cycles. They do not only work with desktops and PCs, but they can read/write data 24/7.
SAS 12Gbps HDDs have received the utmost attention in the market as a result of their high performance. These performance benefits allow it to be useful for a wide variety of applications. For instance, a SAS 12Gbps connection can support up to four wide lanes per connection.
Connecting JBOD with these SAS drives can support up to 1200MB/s. These high-performance drives do not only help handle large workloads; they also offer cost-effective expansion to an already robust system.
Also, each 12Gbps high-performance SAS drive can offer users a rotational speed of up to 15000 rpm.
They provide a great bandwidth enough to perform efficiently. The robust performance of SAS 12Gbps drives clearly a worthy investment for improved performance of servers and desktops. They provide very large amounts of storage options and are a cost-effective choice for users.
Flexibility is one of the best benefits of SAS 12Gbps drives. These drives have configured flexibility, which allows them to work perfectly with several devices without modification or changes. Many of them feature a Universal Serial controller for seamless system support.
SAS 12Gbps hard drives can also be partitioned into a storage pool and assigned to servers for work-intensive applications. They are a perfect fit for server systems, including reservation systems, medical imaging, and more!
Only this range of SAS hard drives can provide users with the best worlds of flexibility. This way, allows them to support use with other drives.
12Gbps SAS-based storage systems have the benefit of dual-port capability. This allows them to provide a redundant path to the drives in case of controller failover. These drives also operate on separate point-to-point connections. That way, it is rare for drive connection loss to affect them.SAS 12Gbps HDDs are built to handle the rigours of heavy workloads and enterprise use. They also safeguard data integrity, thanks to their ability to comprehensively verify data and correct errors.
