Seagate BarraCuda ES 320GB SATA drive
The Seagate BarraCuda ES ST3320620NS is a 320GB 3.5-inch internal hard drive built for desktop systems. It spins at 7200 RPM with a 16MB cache and connects through a SATA 3.0Gb/s interface. Perpendicular recording technology and native command queuing support reliable data handling in everyday workloads.
Suited for always-on desktop storage
This drive carries the highest reliability rating for 24 x 7 operation and includes multidrive firmware that maximises system availability. Its best-in-class rotational vibration tolerance helps maintain performance when installed alongside other drives. Buyers who need larger capacities or faster solid-state speeds should consider other options.
Sustained load behaviour
Under continuous use the 7200 RPM spindle and 4.16ms average latency deliver steady throughput for long-running tasks. The 16MB cache absorbs burst requests while NCQ optimises command order to reduce mechanical seek delays. Rotational vibration tolerance keeps performance consistent in multi-drive enclosures during extended sessions.

คำถามเกี่ยวกับสินค้านี้
Does this drive need a SATA 3.0Gb/s port and a 3.5" drive bay to work?
Yes, it connects via a SATA 3.0Gb/s interface and fits a standard 3.5" internal bay.
Will the 16MB cache and NCQ work with a motherboard that only supports SATA 1.5Gb/s?
The drive is backward compatible with SATA 1.5Gb/s controllers, though throughput will be limited to that speed.
How can I verify the 7200 RPM spindle and 4.16ms latency are performing correctly after installation?
Use a SMART monitoring tool to confirm the spindle speed and run a benchmark to check reported latency figures.
