Dell and HP 3 TB 7.2K RPM SAS Hard Drives are enterprise near‑line SAS (NL‑SAS) hard disk drives designed for servers, storage arrays, and SAN/NAS environments where high capacity and enterprise‑class reliability are important, while performance demands remain moderate. These drives combine a 3 TB storage capacity, 7,200 RPM rotational speed, and a Serial Attached SCSI (SAS) interface to deliver superior reliability, error correction, and multi‑path connectivity compared with standard SATA drives, making them well‑suited for bulk data storage, backups, and scalable storage tiers.
SAS drives from Dell (often used in PowerEdge and PowerVault platforms) and HP (used in ProLiant, Apollo, and storage systems) are typically 3.5″ Large Form Factor (LFF) and hot‑swappable in compatible server backplanes, allowing drive replacement without powering down the system.
3 TB Storage Capacity – large space for bulk or less active datasets.
7,200 RPM Rotational Speed – balances throughput and power efficiency for near‑line workloads.
Enterprise SAS Interface – SAS (typically SAS‑2 at 6 Gb/s or SAS‑3 at 12 Gb/s), with enhanced error correction and multi‑path redundancy vs SATA.
Improved Reliability – SAS drives typically offer higher MTBF and duty‑cycle ratings than SATA; good for 24×7 environments.
Hot‑Swap Support – lets data center admins replace drives without downtime.
3.5″ Large Form Factor (LFF) – fits standard server and storage array bays.
Cache Buffer – most models include a cache (often 64 MB or greater) for buffering read/write workflows.
Supports RAID – integrates with enterprise RAID controllers for RAID 0/1/5/6/10 configurations.
Dual‑Port SAS Optional – many HP SAS drives support dual‑port connectivity for redundancy and multipath I/O.
