Twin Pack for Continuous Shooting

This kit supplies two 32GB CompactFlash cards built for cameras that write long bursts of raw files or high-bitrate video. Each card uses the Parallel ATA interface with a 50-pin connector, matching legacy professional bodies and industrial recorders that still require CF media.

Sustained Write Behaviour

The Parallel ATA bus tops out at 125MB/s, so extended captures are limited by that ceiling rather than by the flash itself. Commercial-grade flash helps maintain steady throughput during long takes, but the interface prevents the sustained rates that modern UDMA 7 or CFast cards can deliver.

Parallel ATA Bus Limits

The 50-pin PATA connection dates from 1994 and caps theoretical throughput at 125MB/s, well below current CFast or XQD speeds. Cards larger than 512GB are not defined for this interface, so capacity growth stops at that boundary. Adapters can bridge CF to IDE or PCMCIA slots, but they inherit the same bandwidth ceiling.

Questions about this item

Does the 50-pin PATA interface generate noticeable heat or draw extra power during all-day shooting?

The cards use the Parallel ATA bus with a 50-pin connector; flash memory has no moving parts so heat and power draw stay minimal even during continuous write cycles.

What host device or adapter must I already own for these CF cards to work?

You need a camera, card reader or adapter with a native CompactFlash Type I slot that accepts the 50-pin PATA interface.

Will these 32 GB cards work reliably in a 1994-era CF slot that only supports smaller capacities?

The 50-pin PATA interface is backward compatible, but very early hosts may have firmware limits below 32 GB; check the host’s maximum supported capacity before use.
