The Dell 1.2TB 10K RPM SAS 2.5″ HDD is an enterprise-grade internal hard drive engineered for server and storage array environments. With 1.2 TB capacity, a 10,000 RPM spindle speed, and a Serial Attached SCSI (SAS) interface, this HDD delivers low latency, high reliability, and strong throughput optimal for enterprise workloads including virtualization, database storage, mail servers, and RAID configurations. Typical SSHD variants support 12 Gbps SAS for higher bandwidth, while some older or budget options use 6 Gbps SAS interfaces.
These drives are usually hot-pluggable in supported chassis and are compatible with Dell PowerEdge servers that feature 2.5″ SAS backplanes, RAID controllers, and enterprise-class service requirements.
1.2 TB Storage Capacity — moderate capacity for performance-tier storage and server volumes.
10,000 RPM Rotational Speed — lower latency and higher IOPS than 7.2K drives for transactional tasks.
SAS Interface (6 Gbps or 12 Gbps) — enterprise-grade connectivity with robust signalling and throughput.
Dual-port SAS (on many models) — enables multi-path redundancy in SAN environments.
2.5″ Small Form Factor (SFF) — fits dense server/storage arrays.
Hot-Swappable (Hot-Plug) — allows drive replacement without powering down when supported by server backplane.
High MTBF and Endurance — typical enterprise reliability designed for 24×7 operations.
Cache (often 128 MB on 12 Gbps models) — improves throughput.
Compatible with a wide range of Dell PowerEdge servers (e.g., R620, R630, R640, R720, R730, T-series etc.) and Dell PowerVault/EMC arrays with SAS 2.5″ bays.
Works with PERC RAID controllers supporting SAS.
Best suited for enterprise applications like virtualization (VMware/Hyper-V), databases (SQL/Oracle), mail servers, and mixed-workload environments.
