500GB BarraCuda 20-pack

This pack contains twenty new Seagate BarraCuda desktop hard drives, each offering 500GB capacity on a SATA 6.0Gb/s interface. The 3.5-inch drives spin at 7200 RPM with 16MB cache and arrive as bare units without retail packaging. They are suited for system integrators or labs deploying many identical volumes.

Builders needing bulk 3.5-inch SATA storage

The drives suit anyone installing multiple 500GB mechanical disks in desktop chassis or external enclosures that accept 3.5-inch SATA drives. Buyers who want solid-state speed, larger individual capacities, or a smaller 2.5-inch form factor should consider other storage types. The bare-drive packaging also means no cables or mounting hardware are included.

SATA 6.0Gb/s interface

The single specification that decides fit is the SATA 6.0Gb/s connection; the host must provide a matching SATA data port and power connector for each drive. Without a compatible SATA controller or backplane the drives cannot be used. No other interface or protocol is supported by these units.

Questions about this item

How does the 16 MB cache affect sustained write performance on the 7200 RPM drives?

The 16 MB cache buffers burst writes before data reaches the 7200 RPM platters, so sustained throughput settles at the drive’s native media rate once the cache fills.

What acoustic and thermal output should be expected from the 3.5" bare drives during all-day operation?

Each 3.5" bare drive produces typical desktop-class seek noise and idle heat; a 20-pack installation requires chassis airflow rated for multiple 7200 RPM spindles.

Which host interface and form factor must the system provide for these SATA 6.0Gb/s drives?

The system needs 20 free 3.5" drive bays, 20 SATA data ports supporting 6.0Gb/s, and matching SATA power connectors for the bare drives.
