Benefits of XQD

[James Lemon]

Three things mark the XQD card as significantly different from previous card formats:​

• Storage size limits​
• Read/write speed limits​
• Very reliable prevention from corruptibility and failure​

Seems fabulous, but we need the other Camera MFRs to join the party!

Nikon is now a relatively minor player

It is fabulous makes other formats appear that they are going backwards compared to this. I am reasonably sure others will join the party!

Except that there aren't enough people experiencing the problems XQD is trying to solve to finance a new format. XQD is likely to stay a niche product.

SD is the de-facto standard. The Secure Digital Ultra Capacity (SDUC) format, described in the SD 7.0 specification, and announced in June 2018, supports cards up to 128 TiB and offers speeds up to 985 MB/s, which is comparable to what the XQD format offers (and higher than what the cited article writes). Yet most customers are pleased with previous formats and far smaller cards. XQD is an expensive solution to problems customers do not have.

Jérôme,

I am so pleased to have this update, as I wondered if Fuji users like myself would be “left behind”. With 50MP and 100MP bodies, the Fuji and other MF and Canon Pro bodies need the more advanced cards.

Any idea whether compatibility is likely to be achieved with SD cards to SDUC by a Firmware upgrade?

The Sony CFexpress Type B memory card is said to be around 3 x faster than Sony’s fastest CFast memory card (with 530MB/s read speed). With a write speed of up to 1480MB/s, the new CFexpress Type B card meets future requirement needs for secure industry data-recording and requirements from professionals to capture hi-resolution images or high-bitrate video (think 8K video).

The Sony FS7 (which records to XQD gen 1 cards) has been around for more than 4 years now (started shipping October 2014) and has dominated the mid-tier corporate, commercial and documentary productions, so it isn’t that unlikely that whatever successor 4K (or maybe 6K or 8K) pro camcorder Sony is cooking it surely has to adopt CFexpress.

Likely not.
