16 GB CompactFlash 300X card

This 16 GB CompactFlash card carries a 300X speed rating and delivers read speeds up to 50 MB/s with write speeds up to 12 MB/s. It uses the Type I form factor and ships in a protective plastic case. The card is designed for high-capacity data storage and communication in compatible devices.

Professionals with legacy CompactFlash slots

Photographers and industrial users whose cameras or equipment still accept CompactFlash Type I media can use this card for reliable capture and transfer. It is not suited for devices that require faster sustained write performance or for systems that only support newer card formats such as CFast or SD.

300X speed rating with 50 MB/s read

The 300X rating translates to a maximum read speed of 50 MB/s and a maximum write speed of 12 MB/s. This single specification determines whether the card can keep up with your device's buffer clearing and continuous shooting demands.

Questions about this item

Will this 16GB CompactFlash card fit a standard Type I slot?

Yes, the card is a CompactFlash Type I device, so it fits any standard CF Type I slot without an adapter.

What is the correct way to insert the card and what step do users often miss?

Align the 50-pin connector with the slot, press firmly until seated, then secure the eject lever; the step often missed is fully engaging the lever so the card does not pop out during use.

How long will the 300X-rated memory last before it needs replacement?

With 16GB capacity and 300X speed rating, the card handles typical photo and video workloads for years; replace it if write errors appear or sustained write speed drops below 12MB/s.
