Capacity and interface
The Seagate ST3250620NS is a 250GB 3.5-inch desktop internal hard drive with a SATA 3.0Gb/s interface. It spins at 7200 RPM and includes a 16MB cache for general storage tasks. The drive uses perpendicular recording technology and native command queuing for reliable operation. It is supplied as a bare drive in new condition.
Enterprise reliability focus
This drive suits users needing a drive rated for 24 x 7 operation with high rotational vibration tolerance. It is not intended for buyers who want larger storage capacities or higher transfer rates than 3.0Gb/s. Systems requiring a smaller form factor or a different interface will need an alternative drive.
SATA 3.0Gb/s interface
The drive connects via a SATA 3.0Gb/s interface, which determines compatibility with the host controller. Average seek time is 8.5ms, average write time is 10ms and average latency is 4.16ms. Verify that your system supports this interface and the 3.5-inch form factor before purchase.

Questions about this item
What SATA host interface must my system provide for the ST3250620NS to operate at its rated 3.0Gb/s transfer rate?
The drive connects via a standard SATA 3.0Gb/s port; any motherboard or controller with a SATA 3.0Gb/s (SATA II) connector will allow it to run at full speed.
Can the 7200 RPM BarraCuda ES share a SATA controller with older, slower drives without limiting their operation?
Each SATA device negotiates its own link speed independently, so the ST3250620NS running at 3.0Gb/s will not force older drives to run faster than they support.
How can I verify the drive is healthy and performing at its specified 8.5ms average seek time after installation?
Run the manufacturer's SeaTools diagnostic or any SMART-capable utility; a passing short self-test and SMART attributes showing no reallocated sectors confirm the drive is working as intended.
