CompactFlash Cards Vs Other Options

CompactFlash cards are widely available and are more robust and durable than their cheaper and smaller cousins – SD cards. So much so that even with the launch of the more compact and high storage SDXC cards and the next-gen CF 2.0 cards CompactFlash cards continue to garner interest among professionals wielding pro cameras.

Which are the best CompactFlash cards?

The best CompactFlash cards are the ones which have a minimum consistent write speed of 65 MB/s, are UDMA 7 rated and come with a minimum replacement warranty of 1 year.

How to verify CompactFlash card read and write speeds?

All CompactFlash cards have a speed mentioned on the label. This speed is invariably the read speed. This is the speed at which it is able to transfer information to a computer. While this is useful, the most important factor is the write speed. The speed at which the camera is able to write information on to the card. This speed will determine whether your recordings will be smooth or not. This should be mentioned on the packaging. You can also Google it prior to purchase.

What is a good CompactFlash card write speed for 4K video recording?

Go for cards that offer you a minimum consistent write speed of about 65 MB/s. While 150 MB/s write speed cards are available, they don’t always offer that speed on a consistent basis. Therefore the actual speed is much less. Look for the alphanumeric label VPG-65.

What is a good CompactFlash card write speed for full HD video recording?

Go for cards that offer a minimum consistent write speed of 20MB/s. That should be enough for recording full HD movies as well as shorts bursts of full-resolution RAW frames.

Are CompactFlash and CFast cards the same?

Not really. Though they share identical dimensions, they are not identical in terms of the underlying technology that drives them. CompactFlash cards use the Parallel ATA interface. However CFast cards use the Serial ATA interface. CFast cards are considered to be the next-gen products in the CompactFlash segment.

What is ‘X’ as labeled on some CompactFlash cards?

X stands for 150KB/s. That is the original write speed that has come down from the heydays of optical media storage devices like compact discs. All modern external recording devices like SD cards and CompactFlash cards bear a reference to the speeds of those legacy devices. If a CF card is labeled as having a speed of 1000x that means the read speed of the card is 150MB/s (150 x 1000 / 1000).
