ProGrade Digital CFexpress cards are coming with speeds up to a crazy 1.6GB/sec

ProGrade Digital has officially announced the launch of their new CFexpress cards. But the range has expanded since they teased us with the 1TB CFexpress card last year at NAB. It’s also gotten a bit of a speed boost, too! Along with a new CFexpress card reader, two lines of CFexpress cards are coming in Gold and Cobalt flavours offering read speeds of up to 1.6GB/sec and write speeds up to 1.4GB/sec.

CFexpress is a straight up drop-in replacement for the XQD cards we’ve seen used in Nikon, Panasonic and Phase One stills cameras. The only thing they need to support CFexpress is a firmware update.

Nikon has announced that a new firmware is coming for the Z6, Z7, and several of their DSLRs, already, but there’s been no confirmation yet from Phase One. And Panasonic’s S1 and S1R mirrorless cameras aren’t even shipping yet, so there’s no indication as to when they might support the fast new format. Whether or not the S1 and S1R will receive CFexpress in the final production version of the firmware is unknown.

Both ProGrade Gold and Cobalt cards share some features in common, with the primary differences between them being the capacities available and the maximum write speeds.

  • Fully compliant with CompactFlash™ Association 1.0 specification
  • NVMe host interface with PCIe Gen3 X2 interconnect
  • Extended battery life and low standby power through NVMe PS0 – PS4 support
  • XQD host interoperable with firmware support
  • Metal enclosure for improved durability and heat dissipation
  • Thermal throttling protects card from overheating
  • Optimized controllers specifically designed for use in professional-grade motion and still capture cameras
  • Unique serialized tracking of every card enabling identification of key components and manufacturing data for the highest quality control
  • Rigorous 100% full card testing down to individual memory chips for optimal quality
  • X-ray proof, shock-proof
  • Temperature ranges: operating 14 to 158°F/ -10 to 70°C; storage -4 to 185°F/ -20 to 85°C
  • Dimensions: 29.6mm x 38.5mm x 3.8mm
  • 3-year warranty

ProGrade Digital CFexpress Cobalt

These are ProGrade’s premium line of CFexpress cards with maximum read and write speeds of up to 1.6GB/sec and 1.4GB/sec respectively. Designed for the highest speed demands, leveraging PCIe, Gen 3 interconnect with a NVMe host controller interface.

  • Maximum read speed 1600MB/s
  • Burst write speed 1400MB/s
  • Minimum sustained write speed 1300MB/s
  • Capacities: 325GB, 650GB

ProGrade Digital CFexpress Gold

The ProGrade Gold spec of CFexpress cards are the closest to the original 1TB announcement, although they’ve also seen a slight speed boost. The maximum read speed has been bumped from 1.4GB/sec to 1.6GB/sec, although the max burst write speed of 1GB/sec remains the same. These come in a wider range of capacities from 120GB up to a whole 1TB.

  • Maximum read speed 1600MB/s
  • Burst write speed 1400MB/s
  • Minimum sustained write speed 1300MB/s
  • Capacities: 325GB, 650GB

ProGrade Digital CFexpress Card Reader

The new ProGrade Digital CFexpress reader is a USB 3.1 Gen 2 (although, apparently not for long) card reader supporting only CFexpress. It’s not dual slot with anything else like the rest of ProGrade’s card readers.

On availability for the cards and the new reader, ProGrade Digital only has this to say…

ProGrade Digital [CFexpress] cards and readers will be available for purchase by the general public as soon as firmware for existing compatible cameras is updated or when new devices are introduced into the market

There has been no word on prices yet, but I would expect the reader to have the same price as ProGrade’s other four card readers (which is around $70). What the cards will cost, though, is anybody’s guess.
