Capacity and Interface
The Seagate Barracuda 7200.11 is a 3.5 inch internal hard drive with a 1.5TB capacity and a SATA 3.0Gb/s interface. It spins at 7200 RPM and includes a 32MB cache for daily computing tasks. The bare drive uses Perpendicular Magnetic Recording technology and supports Native Command Queuing.
Suitability and Limits
This drive suits desktop PCs that need a 1.5TB SATA storage volume for general file storage and operating system use. It is not for systems that require a faster interface than SATA 3.0Gb/s, nor for builds limited to 2.5 inch drive bays. Buyers who need more than 1.5TB of capacity on a single drive should look at larger models.
Deciding Specification
The SATA 3.0Gb/s interface is the single specification that decides compatibility. Your motherboard or controller must provide a standard SATA port operating at 3.0Gb/s to use this drive. Without that port the drive cannot be connected or recognised by the system.

Questions about this item
Does this drive need a SATA 3.0Gb/s port and a standard 3.5-inch bay with power and data cables?
Yes — it connects through a 7-pin SATA 3.0Gb/s interface and fits a 3.5" bay, so you need a matching motherboard port, a SATA data cable and a SATA power lead from the PSU.
Will the 32MB cache and NCQ on this 7200.11 drive work with an older SATA 1.5Gb/s controller?
The drive is backward-compatible with SATA 1.5Gb/s controllers; NCQ and the 32MB cache remain active, though sustained transfer will be limited to the older bus speed.
How can I verify the 1.5TB Barracuda is running at its rated 7200 RPM and 120 MB/s after installation?
Check the SMART data for a spindle speed of 7200 RPM and run a sequential read benchmark; sustained throughput near 120 MB/s confirms the PMR media and 32MB cache are performing as specified.
