Description
More Details
The NFWH2 Dell 12TB 7.2K RPM SAS-12GBPS 256MB is a large capacity, high-performance hard drive. The drive has a capacity of 12 terabytes and runs at 7200 RPM (revolutions per minute). It has a SAS (Serial Attached SCSI) interface with a data transfer rate of 12 Gbps (gigabits per second) and a buffer size of 256MB (megabytes). This drive is likely intended for use in enterprise-level storage systems or data centers.
SAS (Serial Attached SCSI) is a faster, more reliable, and more scalable version of the traditional SCSI interface. SAS is a point-to-point interface that supports multiple devices on a single bus, which allows for faster data transfer rates and more efficient use of bandwidth.
The 12 Gbps SAS interface of this drive allows it to transfer data at rates up to 12 Gbps, which is faster than the 6 Gbps SATA interface. The buffer size of 256MB is a type of memory on the drive that allows the drive to store data temporarily while it is being read or written, which helps to improve performance by reducing the number of times the drive has to access the platters.
This drive is suitable for use in high-availability systems, data centers, and other enterprise-level storage applications that require high-performance and large storage capacity.
High Speed Data Transfer
The NFWH2 Dell 12TB 7.2K RPM SAS-12GBPS 256MB hard drive supports a high-speed data transfer rate of 12 Gbps (gigabits per second) through its SAS (Serial Attached SCSI) interface. This interface is a faster, more reliable, and more scalable version of the traditional SCSI interface. SAS is a point-to-point interface that supports multiple devices on a single bus, which allows for faster data transfer rates and more efficient use of bandwidth.
The 12 Gbps data transfer rate allows for faster data access and transfer speeds, which can be beneficial in high-performance computing environments, such as data centers, where large amounts of data need to be quickly accessed and processed. The high-speed data transfer also allows for faster backups, recovery, and overall improved performance in heavy workloads.
It’s important to note that the actual data transfer rate will depend on various factors, such as the specific storage controller and host bus adapter that the drive is connected to, the RAID level you are using, and the workload. The data transfer rate may be lower than the maximum rate of 12 Gbps if the system is not able to sustain that speed.
Serial Attached SCSI (SAS) HDD
Serial Attached SCSI (SAS) is a computer bus used to connect computer components such as hard drives, and tape drives. It is a point-to-point interface that supports multiple devices on a single bus. SAS is based on the SCSI interface and provides several improvements over it, including faster data transfer rates, better scalability, and improved reliability.
SAS uses a serial signaling method, which allows for faster data transfer rates than the parallel signaling method used by traditional SCSI. SAS also supports multiple devices on a single bus, which allows for better scalability and improved performance.
SAS devices are compatible with SCSI devices, and SAS host bus adapters can connect to SCSI devices using an SCSI-SAS bridge. This allows for an easy upgrade path from SCSI to SAS, as well as the ability to use SAS and SCSI devices together in the same system.
SAS is commonly used in enterprise-level storage systems, data centers, and other high-performance computing environments that require high-performance and high-reliability storage solutions. SAS drives are also hot-swappable, which allows for easy maintenance and upgrades.
