Seagate ST6000NM0275 6TB 3.5" SATA Enterprise HDD SED 7200RPM

The Seagate 6TB 3.5" SATA Enterprise HDD, SED, ST6000NM0275 is a hard disk drive (HDD) for recorders, servers and storage arrays that run around the clock. This is the Enterprise Capacity v5 model.

What each spec means in use

• 6TB capacity. Room for continuous recording from an NVR (network video recorder) or DVR (digital video recorder) with several high-resolution IP or analogue camera streams.
• 3.5-inch form factor. The full-size drive format, not the smaller 2.5-inch laptop size.
• SATA 6Gb/s. Serial ATA interface with a 6 gigabit-per-second link.
• 7200 RPM. The platters turn 7,200 times a minute (revolutions per minute), which suits both sequential and random workloads.
• SED. A self-encrypting drive encrypts data in the drive's own hardware, which helps with security and compliance.
• Advanced Format (AF) 4K sectors. Data is stored in 4K blocks, which improves storage efficiency and suits modern operating systems and recording platforms.
• 24/7 duty. Designed for enterprise and data centre use, with higher workload ratings than desktop-grade drives.

What else you need

A recorder, server or array with a free 3.5-inch SATA bay. It is commonly used in RAID (redundant array of independent disks) setups and multi-drive systems, where sustained write operations and data integrity matter most.
