Questions about this item

How much heat or noise does the 72 RPM 2.5" SATA drive generate when running all day?

The 72 RPM spindle speed and SATA 6 Gbps interface are rated for workloads of 40% or less, keeping heat and acoustic output low in entry server or external storage use.

What must my laptop already have for this 2.5" SATA drive to work?

A free 2.5-inch drive bay and a SATA data and power connection are required for the 1 TB HP 655710-B21 to install and operate.

Will this SATA drive work alongside an older 3.5-inch HP Midline drive in the same system?

Yes, both use the same SATA interface and 6 Gbps maximum transfer rate, so the 2.5" 1 TB drive can share a controller with legacy 3.5-inch HP Midline drives.
