What is IDE (UDMA mode 1)?

IDE (UDMA mode 1) is an Ultra DMA transfer mode of the Parallel ATA interface defined for older PATA devices, offering a theoretical maximum rate around 25 MB/s.

How does byte/second [B/s] differ from bits per second?

Byte per second measures data transfer in bytes where one byte equals eight bits, while bits per second quantifies bandwidth at the bit level.

Can this converter be used for modern SATA drives?

No, the IDE (UDMA mode 1) unit and its conversion apply only to legacy PATA devices, not modern SATA or NVMe interfaces.
