High-capacity 2.5-inch drive
The Seagate BarraCuda 4TB 2.5-inch 15mm drive brings 4000GB of mechanical storage to laptops, all-in-one PCs and external enclosures. Its 128MB cache and SATA 6Gb/s interface keep data moving for everyday workloads. The 15mm z-height fits devices designed for thicker 2.5-inch bays.
15mm form factor and SATA connectivity
The 15mm thickness means the drive slides into compatible laptop bays and 2.5-inch enclosures without adapters. A standard SATA data and power connector provides a direct link to the host system. Multi-tier caching technology helps deliver responsive performance while keeping power draw low.
Thermals noise and power draw
Mechanical operation produces audible seek noise and modest heat typical of spinning disks. Multi-tier caching reduces the frequency of heavy platter activity, which helps limit temperature rise and acoustic output during normal use. Power consumption stays low thanks to the caching architecture and SATA interface efficiency.

Questions about this item
What does the SATA 6Gb/s interface cap in practice?
The SATA 6Gb/s link caps burst throughput at the interface limit; sustained speeds depend on the mechanical drive and system workload.
What physical space does the 2.5-inch 15mm drive need to fit?
The drive is 2.5 inches wide and 15mm thick, so it requires a bay or caddy that accepts 15mm height.
How is the drive installed and what step is often missed?
Connect the SATA data and power cables, secure the drive with screws in a 15mm bay, then initialise and format the volume in the operating system.
