16TB enterprise SATA hard drive

The Seagate Exos X16 is a 3.5-inch internal hard drive built for continuous operation in servers, storage arrays and business NAS systems. It spins at 7200 RPM over a SATA 6 Gbps interface and provides 16TB of capacity in a helium-sealed design. A 256 MB cache and a 2.5 million hour MTBF rating support heavy write workloads.

Suited for bulk storage arrays.

This drive targets administrators who need high-capacity, 24x7 storage for cloud archives, surveillance footage or large-scale backups. The PowerBalance feature optimises watts per terabyte and the helium fill reduces turbulence for denser platters. Buyers who need solid-state latency or a drive for a laptop should look elsewhere.

261 MB/s maximum sustained transfer rate

The headline throughput figure of 261 MB/s determines whether the drive can feed your RAID controller or backup window fast enough. The SATA 6 Gbps link, 7200 RPM spindle and 256 MB cache combine to deliver that rate across the full 16TB. Power-disable support lets the host manage drive power states.

Questions about this item

What host interface must my system provide for the 16TB Exos X16 to operate?

The drive requires a SATA 6 Gbps host interface to operate at its maximum sustained transfer rate of 261 MB/s.

Can the 7200 RPM helium-sealed Exos X16 operate in a NAS with older SATA drives?

Yes, it uses the standard SATA interface so it will work alongside older SATA drives in the same NAS enclosure.

How can I verify the 16TB Exos X16 is performing at its rated 261 MB/s sustained transfer rate after installation?

Run a sequential read or write benchmark such as CrystalDiskMark or ATTO and confirm the results approach 261 MB/s.
