What is IDE (UDMA mode 2)?

IDE (UDMA mode 2), also known as ATA/33, is a Parallel ATA transfer mode that offers a theoretical maximum data transfer rate around 33.3 megabytes per second for synchronous host-drive communications.

Why convert IDE (UDMA mode 2) to MB/s?

Converting to MB/s standardizes legacy transfer rates, making it easier to understand and compare with modern storage device speeds and benchmarks.

Can this conversion be used for modern storage devices?

No, this conversion is primarily applicable to legacy PATA/IDE interfaces and has limited relevance for current storage technologies that use different transfer standards.

Key Terminology

IDE (UDMA mode 2): A Parallel ATA transfer mode also called ATA/33, providing a maximum theoretical speed near 33.3 MB/s for communication between host and drive.
Megabyte per second (MB/s): A unit measuring data transfer rate equal to one megabyte of data transferred each second, where megabyte may be decimal (10^6 bytes) or binary (2^20 bytes).
Legacy PATA/IDE: Older Parallel ATA interface standards used for connecting storage devices before newer technologies became widespread.
