HP 649401-001 500 Gb 7200 Rpm 3.5 Inch Sata Hard Drive With Tray

HP 649401-001 500 Gb SATA Drive

This HP 649401-001 is a 3.5 inch internal hard drive with a 500 Gb capacity. It spins at 7200 Rpm and connects through a Serial Ata-300 interface. The unit ships with a tray for server installation. It suits administrators adding midline storage to compatible HP systems.

Upgrade from smaller midline drives

The drive replaces lower-capacity 3.5 inch SATA units in the same midline class. The jump is worth it when current bays are full and the array controller supports the 300 MB/s link speed. It does not serve workloads that demand faster spindle speeds or larger caches.

SATA 300 interface limits

The Serial Ata-300 interface caps sustained throughput at 300 MB/s regardless of spindle rate. Mechanical latency at 7200 Rpm remains the bottleneck for random I/O patterns. The 3.5 inch form factor requires a matching drive bay and backplane power connector. Builders needing higher throughput or smaller modules must choose a different interface standard.
