Desktop bulk storage 1TB 20-pack

This pack contains twenty new Seagate BarraCuda ST1000DM003 3.5-inch desktop hard drives, each offering 1TB capacity over a SATA 6.0Gb/s interface. The drives spin at 7200 RPM with 64MB cache and 4.16ms average latency. Bare-drive packaging suits system integrators and IT teams deploying large volumes of mechanical storage.

Suited for capacity-first arrays.

These drives suit NAS expansions, surveillance arrays, backup targets and secondary bulk volumes where cost per terabyte outweighs access speed. They are not for boot drives, database logs or any workload that demands SSD-class latency or sustained throughput beyond mechanical limits.

Single-platter 1TB density decides fit

Each drive uses Seagate's first 1TB-per-disk technology, so one platter delivers the full capacity. That design reduces moving parts and helps the 7200 RPM spindle hit the rated 4.16ms latency. Verify your chassis has twenty 3.5-inch bays and your controller supports SATA 6.0Gb/s before ordering.

Questions about this item

Will these 3.5 inch drives fit in a standard desktop drive bay?

Each drive uses the 3.5 inch form factor and a SATA 6.0Gb/s interface, so it mounts in any standard 3.5 inch bay with four M3 screws and connects to a SATA data cable and power connector.

What is the correct way to initialise these bare drives in Windows, and what step is often missed?

After connecting the SATA data and power cables, open Disk Management, initialise the 1TB disk as GPT, then create and format a new simple volume; the step often missed is assigning a drive letter so the volume appears in File Explorer.

When should I expect to replace a drive from this 20 pack under typical desktop use?

Seagate rates the BarraCuda series for standard desktop workloads; with 7200 RPM operation and 64MB cache, plan to review SMART health after three to five years and replace any drive that shows reallocated sectors or rising seek errors.
