Purpose and Audience

The Toshiba HDD2193 is a 40GB 2.5-inch internal hard drive built for laptops that use the IDE Ultra ATA100 interface. It suits owners of older notebooks needing a direct replacement drive with a 44-pin connector.

Who It Suits and Who Should Look Elsewhere

This drive fits machines designed for parallel ATA storage and a 5400 RPM spindle speed. Buyers whose systems require Serial ATA or a larger capacity should look elsewhere.

Deciding Specification

The IDE Ultra ATA100 interface is the single specification that determines compatibility; the drive will only work in bays and controllers that support this parallel ATA standard.

Questions about this item

Should I pick this 40GB model or look for a larger capacity?

This drive is a single 40GB capacity; choose it when a legacy notebook specifically requires a 2.5" IDE Ultra ATA100 drive of this exact size.

What does the 5400 RPM figure mean once the drive is installed in a laptop?

5400 RPM spins the platters at that speed, giving a 12ms average seek time and 5.55ms average latency for typical office and web workloads.

The interface is IDE Ultra ATA100 / ATA-6 — what transfer ceiling does that impose in practice?

The IDE Ultra ATA100 / ATA-6 interface caps the burst transfer rate at 100 MB/s, so sustained throughput will stay below that limit.
