Enterprise 500 GB SATA drive

The Seagate Constellation ES ST3500514NS is a 500 GB 3.5-inch internal hard drive built for server and nearline workloads. It runs at 7200 RPM with a 32 MB cache and a SATA 3.0 Gb/s interface. The design targets Tier 2 environments that need enterprise-class reliability and high data integrity.

Low power draw and vibration tolerance

Enhanced rotational vibration tolerance rated at 12.5 rad/sec from 20 to 1500 Hz protects the drive from chassis and fan vibrations. Seagate PowerChoice technology reduces energy use during idle or slow periods. The drive delivers the lowest power consumption of any nearline 3.5-inch model to cut cooling costs.

Self-encrypting TCG security

TCG-compliant self-encryption secures data at rest without extra software overhead. A 1.2 million hour MTBF and an unrecoverable error rate of 1E10-15 support long-term data integrity. The bare-drive packaging suits system integrators deploying multiple units in storage arrays.

Questions about this item

How do I install this 3.5" SATA drive and what step is often missed?

Mount the drive in a 3.5-inch bay using four screws, connect the SATA data cable to a 3.0Gb/s port and attach a SATA power connector; the step often missed is enabling the drive in BIOS or initialising the disk in the operating system before it becomes visible.

What maintenance or replacement will this enterprise drive need later?

No routine maintenance is required; the drive is rated for a 1.2 million hour MTBF and includes PowerChoice technology for idle power savings, so replacement is only needed if SMART attributes report reallocated sectors or the drive exceeds its rated workload limits.

What limit appears first during sustained write workloads on this 7200 RPM model?

The 3.0Gb/s SATA interface caps sustained throughput at around 300 MB/s, which is reached before the 32MB cache or 7200 RPM platters become the bottleneck during continuous sequential writes.
