4TB 2.5-inch SATA laptop drive
This Seagate ST4000LM016 is a 4TB internal hard drive built for 2.5-inch laptop bays and external enclosures. It spins at 5400 RPM with a 128MB cache and connects over a SATA 6.0Gb/s interface. The 15mm z-height suits ultra-slim desktops and DIY portable storage boxes.
Sustained throughput on sequential workloads
The 5400 RPM spindle and 128MB cache deliver steady sequential transfer rates for large media libraries and backup jobs. Average seek time is 12ms, keeping latency predictable during long copy operations. Lower rotational speed reduces heat and power draw inside confined chassis.
15mm height decides fit
This drive measures 15mm tall, so it only fits bays and enclosures that accept that thickness. Standard 7mm or 9.5mm laptop slots will not accommodate it. Verify your device or external box supports 15mm 2.5-inch drives before purchase.

Questions about this item
How much power does the 5400 RPM mechanism draw during continuous all-day operation?
The 5400 RPM spindle speed and 128MB cache keep power draw low for laptop use, and the 15mm height allows efficient heat dissipation inside a 2.5-inch bay.
My laptop has a SATA 3Gb/s controller; will the SATA 6.0Gb/s interface on this drive work without an adapter?
Yes, the drive is backward compatible with SATA 3Gb/s controllers, so it will operate at the slower link speed without any extra hardware.
Can I install this 15mm high 4TB drive in a bay that currently holds a 9.5mm 2TB laptop drive?
The 15mm height exceeds the 9.5mm bay clearance, so it will not fit in standard thin laptop slots; it is intended for external enclosures or ultra-slim desktop bays.
