Capacity and interface

This 72GB 2.5-inch drive uses a SAS 6Gb/s connection and spins at 15000 RPM. It is built for internal server storage where fast, consistent access matters. Hot-plug support allows replacement without shutting down the system.

Server workloads only

The drive suits administrators who need high-speed, low-capacity storage for transactional databases or boot volumes. It is not for desktop users who want large media libraries or quiet operation. Buyers needing terabyte-scale capacity should look elsewhere.

15000 RPM spindle speed

This rotational speed determines the drive's random-access performance and latency profile. Verify that the target server backplane accepts 2.5-inch SAS drives and that the workload benefits from the speed before purchasing.

Questions about this item

How often will the 15000 RPM SAS drive require maintenance or replacement?

The 15000 RPM SAS drive is built for server workloads and includes hot-plug capability so a failed unit can be swapped without powering down the system.

What limit appears first when the 72GB 15000 RPM drive runs under sustained load?

The 72GB capacity fills quickly in write-heavy server tasks, making storage space the first practical constraint during sustained use.

How much noise, heat or power does the 2.5" 15000 RPM SAS drive produce when running all day?

The 2.5" 15000 RPM SAS drive spins at high speed continuously, generating more heat and audible noise than lower-RPM drives in all-day operation.
