Purpose & Audience

The Toshiba MK1655GSX is a 160GB 2.5 inch internal hard drive built for laptop upgrades or replacements. It suits users who need basic storage capacity for everyday computing tasks on older SATA-based systems.

Deciding Specification

The drive connects through a SATA 3.0Gb/s interface and spins at 5400 RPM with an 8MB cache. This combination determines whether the drive matches the host laptop’s controller and performance expectations for routine workloads.

Thermals, Noise & Power

At 5400 RPM the mechanism runs cooler and quieter than faster desktop drives during normal operation. The lower rotational speed keeps acoustic output modest and power draw restrained for mobile use.

Questions about this item

What real-world speed can I expect from the 5400 RPM platters once the drive is installed?

The 5400 RPM spindle and 8 MB cache deliver typical laptop sequential throughput; random access averages 5.55 ms latency.

What does the SATA 3.0Gb/s interface mean for everyday transfer rates?

The SATA 3.0Gb/s link sets the bus ceiling; actual throughput depends on the 5400 RPM mechanism and 8 MB cache.

Will this 2.5 inch drive fit my laptop bay without an adapter?

The standard 2.5 inch form factor matches most laptop drive bays and caddies; no adapter is required.
