Nearline 250 GB drive

The Seagate NL35 ST3250623NS is a 3.5 inch internal hard drive built for continuous operation in servers or workstations. It offers 250 GB of storage on a SATA 1.5Gb/s interface with a 7200 RPM spindle and 16 MB cache.

Sustained 24x7 workload handling

Workload Management monitors temperature and activity to protect the drive during extended nearline duties. Error Recovery Control streamlines recovery in server environments, while Write Same executes large writes without host overhead for smoother sustained throughput.

Upgrade from desktop-class SATA

This nearline model replaces standard desktop drives where lower failure rates under constant load are required. The jump is worth it for 24x7 arrays or multi-drive deployments that need One-Step Microcode Download for simpler field upgrades.

Questions about this item

How much heat and noise should I expect from the ST3250623NS when it runs 24 hours a day?

The NL35 series includes Workload Management that monitors temperature and activity to protect the drive during continuous operation, and it is built to meet 24x7 storage application requirements.

What must my system already have to install this bare ST3250623NS drive?

You need a free 3.5-inch drive bay, a SATA 1.5Gb/s data cable and a matching SATA power connector from your power supply.

Will the ST3250623NS work reliably alongside older SATA drives in the same machine?

Yes, its SATA 1.5Gb/s interface is backward compatible with earlier SATA revisions, and Error Recovery Control helps maintain uptime in mixed-drive server environments.
