HGST
A 600 GB enterprise hard drive spinning at 15,000 RPM with a SAS interface and 64 MB cache
The HGST Ultrastar 15K600 HUS156060VLS600 is a 600GB 3.5-inch internal hard drive built for enterprise workloads. It spins at 15000 RPM and connects through a SAS 6Gb/s interface with 64MB cache. This drive suits servers and storage arrays that demand high transaction rates and low latency. It is not for buyers who need larger capacities or solid-state speeds.
The 15000 RPM spindle delivers an average seek time of 3.4ms and average latency of 2ms for consistent random I/O performance. The 33% capacity increase over the previous generation allows more data per spindle without sacrificing rotational speed. The SAS interface maintains 6Gb/s transfer rates during extended operations. Thermal output and power draw rise under continuous load, so adequate airflow is required.
The bare drive measures 25.8mm height, 101.6mm width and 146.2mm length for standard 3.5-inch bays. SAS backplanes or controllers must support 6Gb/s speeds to avoid link negotiation failures. Missing tray brackets often delay deployment in hot-swap chassis. Firmware mismatches between drive and controller can cause detection errors on first boot.

| Features | The Ultrastar 15K600 combines ultimate performance with high capacity in a single drive, storing up to 600GB of data while spinning at 15,000 RPM. That amounts to a capacity growth of 33% over its predecessor to keep pace with digital data growth and improve space efficiency in today’s data centers. At the same time, sequential performance increased by 23% compared to prior generation to keep data moving faster. The 64MB cache buffer is the largest in the industry in its class. The 6Gb/s Serial Attached SCSI (SAS) and 4Gb/s Fibre Channel Arbitrated Loop (FCAL) interfaces support the |
