Manufacturer description

The Sony XQD G Series 64GB card (QDG64E/J) is built for photographers whose cameras stall before their cards do. Sony rates it at a maximum 440MB/s read and 400MB/s write, the headroom that keeps a DSLR buffer clearing during continuous burst sequences and 4K video writing without dropped frames. Because it supports both PCI Express Gen2 and USB 3.0, offloading a full card to a PC through a compatible reader takes a fraction of the time an SD workflow needs. Durability is where the G Series earns its professional label. The pins sit recessed inside the shell, shielding contacts from dust…

SpecPicks Verdict

SpecPicks scored Sony Professional XQD G Series 64GB Memory Card using a rating × review-volume × price-fit model applied to published specs and reviews across the PC & gaming hardware category. Sony's PC & gaming hardware lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for PC & gaming hardware of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

How fast is the Sony XQD G Series 64GB card?

Sony rates it at up to 440MB/s read and 400MB/s write. Those maximums require an XQD-compatible camera and a PCI Express Gen2 or USB 3.0 host. Note the product title lists 400MB/s read and 350MB/s write, so treat 440/400 as the peak manufacturer spec rather than a guaranteed sustained rate.

Will this card work in my camera?

Only if the camera has an XQD slot. The card does not fit SD, microSD, or CompactFlash slots. Check your camera manual for XQD support and any firmware requirement before ordering.

Do I need a special reader to transfer files?

Yes, an XQD-compatible reader. The card supports PCI Express Gen2 and USB 3.0 for high-speed transfers to a PC, but a standard SD card reader will not recognize it.

Is 64GB enough for 4K video and burst shooting?

That depends on your camera's bitrate and frame rate. Sony positions this card specifically for 4K video and high-speed continuous burst shooting with DSLRs, but for full shoot days most photographers rotate several cards rather than rely on a single 64GB card.

How reliable is it, and what happens if files get corrupted?

The shell is reinforced with recessed pins for contact protection, Sony's File Rescue software is available to recover lost or damaged photos and videos, and the card carries a five-year limited warranty. Check the product listing for current warranty terms in your region.
