Purpose-built nearline drive
The Seagate Constellation ST9500530NS is a 2.5-inch enterprise-class hard drive with 500GB capacity, 7200 RPM spindle speed and a 32MB cache. It connects over a SATA 3.0Gb/s interface and is sold as a bare drive in new condition.
Suited for nearline tiers, not primary boot
This drive suits system builders who need cost-effective, low-power nearline storage in a 2.5-inch chassis for tiered environments or direct-attach arrays. It is not for buyers who require a current manufacturer warranty, larger capacities or the higher throughput of modern solid-state storage.
The SATA 3.0Gb/s interface decides fit
The drive uses the SATA 3.0Gb/s interface, so the host system must provide a compatible SATA port and power connection. Average latency is 4.16ms at 7200 RPM. Verify that your chassis, backplane or caddy accepts a standard 2.5-inch SATA drive before purchase.

Questions about this item
How does the 7200 RPM spindle speed affect sustained throughput limits?
The 7200 RPM rotation provides consistent mechanical throughput for nearline workloads, with a 4.16 ms average latency that defines the drive's sustained random-access ceiling.
What are the heat and noise characteristics when the drive runs continuously in a 2.5" bay?
Designed for low power usage in 2.5" chassis, the Constellation drive maintains manageable heat and acoustic levels during all-day direct-attach or tiered storage operation.
Which host interface must my laptop or enclosure provide for this ST9500530NS to work?
The drive requires a SATA 3.0Gb/s port; it connects via the standard SATA data and power connectors found on compatible 2.5" laptop bays or drive enclosures.
