Dell 2TB 7.2K SATA 6Gbps Hot-Plug Server Hard Drive

The Dell SATA hot-plug drive is a 7.2K RPM nearline hard drive for building large-capacity RAID arrays in Dell PowerEdge rack servers, where cost-per-terabyte is the primary driver and sequential throughput is more important than random I/O performance.

Dell SATA hot-plug drive — 7.2K Nearline Rack Server Storage

SATA nearline drives deliver the best cost-per-terabyte in the Dell server hard drive portfolio. At 2TB per drive, they reduce the number of drives needed to build a given storage pool versus 1TB drives, lowering drive bay consumption and array cost. The hot-swap form factor allows drives to be added to an active RAID array or a failed drive replaced without powering down the server. Dell PERC RAID controllers manage hot-spare activation and RAID rebuild automatically. The 7.2K RPM SATA interface provides adequate throughput for backup, file serving and archiving workloads that are predominantly sequential in nature. Find details at the Dell website.

Large RAID Arrays for South African Rack Servers

South African businesses running PowerEdge rack servers for centralised file storage, backup targets and data archiving will find 2TB drives significantly more efficient than 1TB when building large storage pools. An eight-bay rack server with 2TB drives in RAID 6 delivers approximately 12TB of usable, dual-fault-tolerant storage. For backup workloads, this capacity is relevant: a typical South African SME may accumulate 3–5TB of backup data annually across file shares, virtual machine images and databases. On-premises backup storage is particularly important in South African environments where load shedding makes cloud-only backup unreliable during outages.

RAID Configuration Guidance

RAID 6 is recommended for arrays with six or more drives at this capacity. The growing RAID 5 rebuild window on multi-terabyte drives creates meaningful risk of a second drive failure during rebuild. RAID 6 tolerates two simultaneous drive failures. For eight drives in RAID 6, 75% of raw capacity is usable. Dell PERC H355 or H745 controllers are the recommended adapters for arrays of this scale.
