What does XQD stand for?
Table of Contents
XQD is a media card format that was designed to be a successor to the CompactFlash card. XQD has been adopted by Nikon and was first incorporated into the D4 and D4S and subsequently into the D5, D500 and D850 DSLRs and Z 7 and Z 6 full-frame mirrorless cameras.
Is XQD the same as SD?
XQD cards differ physically from the other card formats in the current market. Compared to a Compact Flash card, the XQD is slightly smaller. With the contact end of the card pointing down, an XQD card has a vertical rectangle shape, similar in proportions to an SD card, but significantly larger.
Are XQD and CFexpress the same size?

One of the main reasons for this is that CFexpress Type B cards are physically the same size as, and pin-for-pin identical to, another card type – XQD cards. So if a camera has an XQD slot, then usually all it needs to become CFexpress compatible is a firmware update.
What is Sony XQD?

Now, you might be thinking this looks familiar, and you’d be right. CFexpress Type B and XQD use the same exact form factor and connectors. Because of this, many cameras, such as Nikon Z Series and Panasonic S Series, which originally had XQD card support, have been able to enable CFexpress via firmware updates.
What is CFexpress XQD?
CFexpress uses the PCIe 3.0 interface and can offer 1 to 4 lanes of 1 GB/s transfer. It will also work with NVMe for faster performance. Based on these numbers, you can have a card that transfers data at a rate of 4 GB/s. That is amazing. XQD can only reach target speeds of up to 0.5 GB/s.
