4 TB desktop storage drive

This 3.5 inch internal hard drive provides four terabytes of capacity for desktop computers. It spins at 7200 RPM to deliver consistent read and write performance for everyday workloads. The drive is supplied new in retail or OEM packaging depending on stock. It suits users who need large, affordable bulk storage inside a standard tower.

Suits bulk storage, not speed-critical tasks

The drive fits builders adding mass capacity for media libraries, backups or archival files where cost per terabyte matters most. It is not suited for buyers who need low latency for operating system boots or application launches. Systems limited to 2.5 inch bays cannot accommodate the 3.5 inch form factor. Workloads demanding sustained high throughput should consider faster storage technologies.

7200 RPM spindle speed

The 7200 RPM rotation rate determines the drive's baseline sequential throughput and access latency. This single figure lets you judge whether the device meets the performance envelope of your intended workload. No other specification in the data sheet overrides this characteristic for mechanical drives. Match the spindle speed to your performance expectations before purchasing.

Questions about this item

Does the 7200 RPM spindle speed hit a thermal limit during sustained writes?

The drive runs at 7200 RPM with a 4 TB capacity; sustained workloads will be constrained by the mechanical speed and heat dissipation of a 3.5 inch desktop drive.

How much noise and heat does the 7200 RPM mechanism produce when running all day?

A 3.5 inch 7200 RPM hard drive generates audible seek noise and measurable heat during continuous operation; ensure your case has adequate airflow for a desktop drive.

What drive bay and mounting hardware must my desktop already have for this 3.5 inch drive?

Your system needs a free 3.5 inch internal bay and standard mounting screws to secure the Lenovo 00MM730 inside the chassis.
