Seagate
A 6 TB enterprise hard drive with 7200 RPM, 256 MB cache and 12 Gb/s SAS interface for 24×7 bulk-data workloads
The Seagate ST6000NM0105 is a 6 TB 3.5-inch internal hard drive built for enterprise capacity tiers. It spins at 7 200 RPM with a 256 MB cache and uses conventional magnetic recording technology. The drive connects through a 12 Gb/s SAS interface that also supports SATA 6 Gb/s operation. It is engineered for continuous 24x7 workloads in replicated and RAID multi-drive storage servers.
Before ordering, verify that your host bus adapter or RAID controller presents a 12 Gb/s SAS port and can address 4Kn logical sectors. The drive requires a SAS backplane or cabling that carries the dual-port SAS protocol; a SATA-only backplane will not negotiate the link. Confirm the server chassis accepts a 26.10 mm high 3.5-inch form factor and that firmware supports the advanced write caching algorithms.
The drive is rated for a 550 TB per year workload, ten times typical desktop ratings, and uses dual processors with a top-cover-attached motor to maintain consistent throughput in dense arrays. A humidity sensor and ramp-load technology protect the heads during vibration and temperature shifts. Average latency is 4.16 ms. Power draw varies with seek activity but remains within standard enterprise 3.5-inch limits for the given form factor.

Versi lain model ini
Keluarga yang sama, memori, penyejuk atau kelajuan jam yang berbeza — bandingkan sebelum membuat keputusan.
The drive ships as a bare 3.5-inch unit only; rails, cables and any carrier trays are not included and must be sourced separately.
Select this 4Kn SAS variant when the controller and RAID firmware require native 4Kn sector addressing; a 512e model would present emulated 512-byte sectors instead.
The 12 Gb/s SAS link provides full-duplex bandwidth to the backplane, supporting the 7200 RPM mechanism and 256 MB cache for sustained enterprise workloads.
