Enterprise bulk-data drive
The Seagate Exos 7E8 ST3000NM0025 is a 3TB 3.5-inch internal hard drive built for enterprise storage servers and arrays. It spins at 7200 RPM with a 128MB cache and connects through a SAS 12Gb/s interface using 512n sector formatting. The drive is engineered for continuous 24x7 operation with a 550TB per year workload rating and conventional magnetic recording technology.
Suited for RAID and replicated storage
This drive fits administrators deploying high-capacity nearline storage in multi-drive chassis where consistent performance and dual-processor reliability matter. Advanced write caching and a humidity sensor support dense environments. It is not suited for desktop PCs lacking SAS infrastructure or for systems requiring SATA-only connectivity. The bare-drive packaging also assumes the buyer provides mounting hardware.
Deciding specification: SAS 12Gb/s interface
The single specification that decides compatibility is the SAS 12Gb/s interface. The host controller, backplane and cabling must support this protocol; a SATA-only motherboard or HBA cannot communicate with the drive. Verify the storage server or RAID controller accepts 12Gb/s SAS devices before purchase.
