Enterprise-Grade SATA Drive

The Seagate BarraCuda ES ST3400620NS is a 400GB 3.5-inch internal hard drive built for desktop and enterprise storage. It spins at 7200 RPM with a 16MB cache and connects via a SATA 3.0Gb/s interface. The bare-drive unit is supplied new and rated for continuous operation in demanding environments.

Suited For RAID And Always-On Arrays

This drive suits system integrators and IT managers who need a reliable SATA drive for RAID arrays, backup servers or high-duty-cycle workstations. It is not for buyers who need a faster interface than 3.0Gb/s, nor for users who require a larger cache than 16MB for sustained random workloads.

SATA 3.0Gb/s Interface Decides Compatibility

The single specification that determines fit is the SATA 3.0Gb/s interface. Your motherboard or controller must support this exact link speed to recognise the drive at full performance. Verify the host connector before purchase.

商品問答

What is the cache size that limits sustained write throughput on the ST3400620NS?

The 16MB cache buffers bursts, but sustained writes are limited by the 7200 RPM platters and SATA 3.0Gb/s interface.

How much heat and noise does the 3.5-inch 7200 RPM drive produce during all-day operation?

Expect typical 3.5-inch enterprise drive acoustics and heat; a standard drive bay with airflow keeps temperatures in spec.

Which SATA host interface must the system provide for this 3.0Gb/s drive to work?

Any SATA 1.5Gb/s or 3.0Gb/s port on a desktop motherboard or RAID controller will run the drive at its rated speed.
