Questions about this item

Will the 32 MB cache need any maintenance or replacement over time?

The 32 MB cache is built into the drive controller and has no user-serviceable parts; it does not require maintenance or separate replacement.

What limit appears first when the 7200 rpm drive runs continuously?

Sustained operation at 7200 rpm will hit the mechanical throughput ceiling of the platters before any electronic bottleneck.

How much noise, heat or power does the 2.5-inch 1 TB drive produce all day?

The 2.5-inch form factor keeps power draw modest and acoustic output low compared with larger desktop drives during all-day use.
