SKU CH-A7AC-Z5709

A 2 TB, 7200 RPM SATA desktop drive with 64 MB cache that ships in an interposer caddy

  • 2 TB capacity stores large datasets and media libraries
  • 7200 RPM spindle speed delivers responsive read and write performance
  • SATA 6 Gb/s interface provides high-throughput connectivity to desktop systems
  • 64 MB cache buffers bursts for smoother sustained transfers
  • Includes interposer caddy for direct 3.5-inch bay installation

Dell EqualLogic 2TB SATA HDD

This Dell EqualLogic drive delivers 2TB of storage on a 3.5-inch SATA 6Gb/s interface spinning at 7200RPM. It includes a 64MB buffer and ships with an interposer caddy for direct mounting in compatible Dell EqualLogic arrays or standard 3.5-inch bays. The unit is new and carries firmware KD03.

Thermals noise and power

As a 7200RPM mechanical drive it produces audible seek noise and measurable vibration during normal operation. Heat output is typical for a 3.5-inch SATA disk under sustained read or write loads and requires standard case airflow. Power draw follows conventional 3.5-inch SATA specifications without additional connectors.

Build quality and mounting

The supplied interposer caddy secures the drive in Dell EqualLogic hot-swap trays and aligns the SATA data and power connectors for tool-less insertion. Without the caddy the bare drive fits any standard 3.5-inch bay using four side screws. The 64MB cache and 6Gb/s link support typical bulk storage workloads but the drive lacks SSD-class latency or endurance for heavy random I/O.

Questions about this item

How do I install the included interposer caddy into a Dell EqualLogic array?

Slide the drive into the supplied interposer caddy until the SATA connectors engage, then insert the whole assembly into the hot-swap bay until the latch clicks.

What maintenance will the ST32000644NS need over its service life?

No scheduled maintenance is required; keep the system fans clean so the 7200RPM drive stays within its operating temperature range.

What limit appears first during sustained writes on this 6Gbps SATA drive?

The 64MB cache fills quickly, so sustained throughput settles at the mechanical 7200RPM transfer rate rather than the interface maximum.
