16 TB CMR drive for enterprise arrays

This 3.5 inch hard drive uses conventional magnetic recording and a SATA 6.0Gb/s interface to deliver 16 TB of capacity. It spins at 7200 RPM with a 256 MB cache and is sold as a 20 unit factory pack. The helium sealed design reduces power draw and weight for large scale deployments.

Fits standard 3.5 inch bays with SATA power and data

Each drive mounts in a typical enterprise chassis or NAS bay using the common SATA connectors. The sealed helium construction removes the need for internal air management while the digital environmental sensors report operating conditions to the host system. No special mounting hardware or cabling beyond standard SATA is required.

Sustained throughput tuned for hyperscale workloads

The firmware is optimised for continuous large transfers and low latency rather than burst performance. Digital sensors adjust internal parameters during extended operation to maintain consistent throughput. The helium fill reduces turbulence at 7200 RPM, helping the drive sustain its rated speed under heavy multi user loads.

Questions about this item

At what point does the 256 MB cache become the bottleneck during sustained 7200 RPM writes?

The 256 MB cache buffers burst traffic before the 7200 RPM platters must accept the data; once the buffer fills, throughput settles to the sustained media rate of the CMR recording layer.

How does the helium sealed design affect power draw and acoustics in a 20 drive rack running continuously?

Helium reduces internal drag so each 16 TB unit draws less power and runs quieter than an air filled equivalent, lowering aggregate heat and noise in a 20 drive deployment.

What host interface must the server or storage array provide for these 3.5 inch drives?

Each drive connects through a standard SATA 6.0 Gb/s port; the backplane or HBA must supply one SATA data and power connector per drive.
