The ST4000NM001A is a 4TB hard disk drive manufactured by Seagate, designed for enterprise use. It is a part of the Exos 7E8 series of hard drives and comes with a 7.2K RPM rotational speed, 4KN sector size, and a SATA 6Gbps interface. In this article, we will explore the technical specifications of the ST4000NM001A Seagate Exos 7E8 4TB 7.2K RPM SATA 6GBPS 4KN 3.5inch Hard Drive and explain them in simple terms.
Storage CapacityThe Seagate Exos 7E8 hard drive has a storage capacity of 4 terabytes, which is equivalent to 4,000 gigabytes or 4,000,000 megabytes. This amount of storage makes it ideal for storage-intensive applications, including video files, high-resolution images, and databases.
Rotational SpeedThe ST4000NM001A hard drive has a rotational speed of 7,200 RPM, which means that the disk platters inside the drive rotate 7,200 times per minute. The higher the rotational speed of a hard drive, the faster it can read and write data. A higher RPM also means that the drive can access data stored on different parts of the disk more quickly.
SATA InterfaceThe Seagate Exos 7E8 hard drive uses the SATA (Serial Advanced Technology Attachment) interface to connect to a computer's motherboard. SATA is the most common type of interface used in modern hard drives, and it provides a high-speed connection between the hard drive and the motherboard. The Seagate Exos 7E8 hard drive supports SATA 6Gbps, which means that it can transfer data at a maximum rate of 6 gigabits per second.
4KN Sector SizeThe ST4000NM001A hard drive uses a 4KN sector size, which means that each sector on the drive contains 4,096 bytes of data. This is the new standard sector size for hard drives, replacing the older 512-byte sector size. The 4KN sector size allows for more efficient use of disk space and reduces the overhead associated with managing large numbers of small files.
Form FactorThe Seagate Exos 7E8 hard drive has a form factor of 3.5 inches, which is the standard size for desktop computer hard drives. The 3.5-inch form factor is larger than the 2.5-inch form factor used in laptop hard drives, which means that the Seagate Exos 7E8 hard drive cannot be used in laptops or other portable devices.
ReliabilityThe Seagate Exos 7E8 hard drive is designed for use in enterprise environments, which means that it is built to be highly reliable. It has a mean time between failures (MTBF) rating of 2.5 million hours, which means that it is expected to operate reliably for a long period of time. The hard drive also features Seagate's PowerBalance and PowerChoice technologies, which help to reduce power consumption and extend the life of the drive.
Data Transfer SpeedThe ST4000NM001A hard drive has a maximum data transfer rate of 600 MB/s. This speed is achieved through the SATA 6Gbps interface, which provides a high-speed connection between the hard drive and the motherboard.
CacheThe Seagate Exos 7E8 hard drive has a cache size of 128MB. The cache is a small amount of high-speed memory located on the hard drive that stores frequently accessed data. By storing this data in the cache, the hard drive can access it more quickly, which improves overall performance.
