250 GB Momentus 7200.4 laptop drive

The Seagate ST9250410ASG is a 2.5-inch internal hard drive built for notebooks that need more capacity and faster access than a standard 5400-RPM unit. It spins at 7200 rpm and carries a 16 MB buffer over a SATA/300 interface. The drive draws only .05 percent more power than a 5400-RPM laptop drive while delivering higher throughput. It suits users upgrading an older laptop or replacing a failed drive in a 2.5-inch bay.

Fits a 2.5-inch SATA bay

This drive slides into any 2.5-inch internal bay with a SATA data and power connection. Its 0.4-inch height matches the standard slim profile used in most notebooks and some compact desktops. The SATA/300 link requires no extra cabling or adapter beyond the laptop’s own connectors. Hot-swap capability is listed, so the drive can be removed in supported bays without powering down the system. It frees the builder from hunting for legacy PATA ribbons or special brackets.

Upgrades from 5400-RPM laptop drives

The jump is worthwhile when the current drive feels sluggish on boot, application launch or large file copies and the system still uses a mechanical 5400-RPM unit. The 7200 rpm spindle and 16 MB buffer cut latency and raise sustained transfer rates without changing the power budget. Buyers who need solid-state speed or capacities above 250 GB will not be served by this model. It also does not fit systems that only accept 1.8-inch or M.2 form factors.
