1.2TB SAS enterprise drive

The Dell AL14SEB120NProduct is a 1.2TB 2.5-inch internal hard drive built for enterprise storage systems. It connects through a SAS 12Gb/s interface and spins at 10000 RPM for fast data access. The drive uses SLC NAND flash memory and is supplied as a bare unit without a carrier.

Capacity and 10K spindle headroom

The 1.2TB capacity suits databases, virtualisation hosts and transaction logs that demand low latency. The 10000 RPM spindle keeps average latency tight for random read and write workloads. Sequential throughput will saturate the 12Gb/s link before the mechanical limit is reached. Workloads needing multi-terabyte volumes or archival cold storage will outgrow this single drive.

Hot-swap tray and PowerVault compatibility

The bare drive is designed for hot-swap bays in Dell EMC PowerVault MD32XX and MD36XX series arrays. No mounting brackets, cables or management software are included in the package. Installation relies on the enclosure’s carrier and backplane for power, cooling and SAS connectivity. Buyers using non-Dell chassis must source a compatible 2.5-inch SAS tray separately.
