DELL 400-ANGI 8TB 3.5" SAS 12Gb/s 7200 RPM internal hard drive

Dell 400-ANGI 8TB Nearline SAS Drive

This Dell 400-ANGI is an 8TB 3.5" internal hard drive built for nearline workloads. It connects through a SAS 12Gb/s interface and spins at 7200 RPM. The bare-drive unit supports hot-swap trays for quick replacement in compatible enclosures. It suits administrators who need reliable bulk storage in Dell or standards-based servers.

Capacity and headroom for nearline duties

Eight terabytes provides substantial room for backups, archives and secondary data sets that are accessed regularly but not continuously. The 7200 RPM spindle delivers steady throughput for sequential reads and writes across the full capacity. Random I/O performance will taper off under heavy concurrent request queues typical of primary database or virtualisation workloads. The drive is not designed for write-intensive, low-latency tiers.

SAS 12Gb/s interface practical limits

The 12Gb/s SAS link caps maximum burst transfer at the bus rate, while sustained throughput is governed by the 7200 RPM mechanics. Dual-port SAS enables multipath redundancy but does not double single-stream bandwidth. Cable length, expander topology and controller queue depth all affect realised performance. The drive cannot saturate the interface with random small-block access patterns.
