Once thermal throttling kicks after a few minutes of continuous reading and writing, speeds drop to around 436.8 MB/s Write and 334.2 MB/s Read. Thermal Throttling occurs very quickly, after about a minute, much quicker than the Prograde card. I did test the Prograde card first so this quicker ramp up into the thermal throttling could be from the reader being slightly warmer to start. Delkin is the latest brand to release CFexpress cards and their Power card might just be the best bang for the buck.

Capture high-quality images and seamless RAW 4K video with the Lexar Professional CFexpress Type B card. ProGrade Digital offers an industry-leading, high-speed workflow reader to match-up with our high-speed memory cards. The PG05.5 Dual-Slot CFexpress Type B and SDXC Reader utilize the new USB 3.2, Gen 2 interface with the capability to read CFexpress Type B and SDXC memory cards at speeds up-to 1.25GBytes per second. That type of performance means that you can download content from our CFexpress Type B and SDXC cards at over 1250MB per second. However, all three measurements for read speed (80%), write speed and usability (10% each) are included in the overall rating.

With speeds of up to 4 GB/s, the standard surpasses the old CompactFlash by a factor of 24! Even the S-ATA-based CFast 2.0 with a maximum of 600 MB/s is left behind. After several years of focusing on NVMe solutions, Sabrent has expanded its memory product offerings, starting with UHS-II SDXC solutions we reviewed back in April. In its 2.0 revision, CF Express lives on the PCIe 3.0 specification with controls for the NVMe protocol. This births three types of CFx solutions that include Type-A, B, and C cards, and adding to this, XQD has, for the most part, been swallowed up by these new solutions.

Sweet product!

The better the overall rating, the higher the compatibility across different cfx card cards and the more convenient the operation. The write speed only accounts for 10% of the overall rating, since, as the name suggests, the focus is usually on the read speed of card readers. The Sony CFexpress Type A memory cards come in two sizes, 80GB and 160GB. Each size is rated at the same read and write speeds and the size we benchmarked was the 80GB size. On the Test Bench today we have the brand new release of the Sabrent Rocket CFExpress B 512GB and 1TB cards, along with their newest CFExpress Type B card reader. Sabrent specs speak to 1700MB/s read and 1500MB/s write on a PCIe 3.0 x2 interface with up to a 3W power draw and up to 400MB/s sustained write performance .

  • The article mentioned a firmware upgrade to address compatibility with the Canon EOS R5 camera in late September 2020.
  • Dual PCIe 3.0 lanes to reach speeds of up to 1,800 MB/s for reads and 1,700 MB/s for writes to give you the fastest transfer rates possible.
  • The edge puts storage devices up against severe environmental challenges and unique demands.
  • To test these new CFx solutions, Sabrent sent over their CFx card reader.
  • CFexpress Type-A memory cards are a new format that Sony has been adopting for many of their new full-frame mirrorless cameras.

On 24 October 2019, Canon announced the development of the EOS-1D X Mark III with dual CFexpress slots. The camera was officially released on 6 January 2020, with availability set for February. Needs to review the security of your connection before proceeding.

Memory card readers are also more reliable than transferring files directly from the device. We also found in the test that not every card reader achieves the maximum speed with every memory card. Therefore, we use a total of three CFexpress memory cards (Angelbird AV Pro XT 660 GB, Lexar Professional 1,750 MB/s, SanDisk Extreme Pro 1,700 MB/s) to measure the maximum possible read speed and give the maximum value in the table.

Big Storage in a Tiny Card

The magnetic back is really convenient – it makes it easy to attach to my desktop. This demonstration was performed using a Thunderbolt 3 CFexpress/XQD reader on a MacBook Pro computer. CFexpress is a standard for removable media cards proposed by the CompactFlash Association . The standard uses the NVM Express protocol over an PCIe 3.0 interface with 1 to 4 lanes where 1 GB/s data can be provided per lane. There are multiple form factors that feature different PCIe lane counts.

Can I use SD card in CFexpress slot?

Yes, it may offer the lowest performance of the lot, but these cards can fit into a combi slot that will also take SD cards. The A7S III has two card slots, both of which will accept SD and CFexpress cards.

The Sabrent solutions use a metal chassis with surrounding plastics to soften edges. The quickest of these solutions is the Type-C card, which offers four lanes of PCIe connectivity and a max speed of 4GB/s. The Sabrent Rocket solutions all use Type-B, a two-lane interface with peak speeds of 2GB/s; the Rocket CFx is rated at 1.7GB/s. CFexpress Type A Cards use the NVMe PCIe 3.0 x4 bus with a single lane. The main difference between type A and type B cards other than their size is that Type B cards use a dual-lane system for speeds up to 1700MB/s whereas Type A cards only have a single lane throughput for a GAL max speed of 800MB/s. It seems the Prograde card has a more gradual decline in performance as it thermal throttles, whereas the Sony card dropped quickly to around 300MB/s read and write.

Yet others experienced things such as cfx cards that weren’t recognized, cards that froze during specific video recording…or others that stuttered. Extreme heat was also common with first generation cards, the user learning the hard way while trying to remove cards immediately, cards that might typically be as high as 85°C. It features blazing speeds of up to 1750MB/s read, and up to 1000MB/s write. A memory card reader is the fastest way to transfer data to or from a memory card. Some readers, like our dual-slot CFexpress and SD Card Reader, allow you to insert multiple cards making transfers even faster.

A 1-year warranty will be extended to a 2-, 3-, or 5-year warranty depending on the product type. With the PCI 3.0 interface, CFexpress cards can keep up with bursts of continuous still images and cinematic video recording in 8K. Please note that this CFexpress card is only compatible with devices that support the CFexpress format, as well as XQD devices that have been updated to support CFexpress. Pulling the drives out, it’s worth noting these are Type-B CFx cards; this form factor is identical to XQD and, from what I gather, is interchangeable.

Delkin cards are the newest cards added to the benchmarks and it could just come down to slightly newer flash. CFexpress Type-A cards are slightly smaller, although thicker, and faster than UHS-II memory. For our testing today, we will be relying on the pictured PCIe 3.0 x4 CFExpress reader created for us by Lexar some time ago. As a bit of confirmation, we always test with multiple readers we have on hand and of both the ThunderBolt 3 and the newer USB 3.2 2×2 spec.

Do people still use CF cards?

Small memory cards allow users to add data to a wide variety of computing devices. CF cards today are primarily used as removable memory for higher-end digital photo and video cameras.

Without a doubt, the toughest lesson learned on release of the Canon EOS R5 Mirrorless camera was that of storage and this relatively new thing called sustained write performance. Countless people purchased these cameras, along with first generation CFExpress Type B cards that had not been approved by Canon. They quickly learned that features that should be available within their camera settings just weren’t there, features such as 4/8K video RAW recording.

It features two new card formats (“type A”, one lane, more compact and “type C”, four lanes, bigger and thicker, up to 4 GB/s), with the existing cards designated as “type B”. For the CFx solutions, we once again come away satisfied with the performance, having no issues in our testing. While simple, CDM did show these drives were more than capable of providing the near 1700 MB/s read and 1200 MB/s write, the 1TB drive reaching near 1350 MB/s at peak. The speeds drop to around 317.4MB /s Write, and 285.4MB/s read and the card is fairly painful to touch due to high temperatures. When looking at Reading Speeds, it looks like the Delkin cards are performing the best right now, just ever so slightly faster than the Prograde cards.

On 13 June 2017, Delkin introduced the first CFexpress cards based on the CFexpress 1.0 specification. In February 2018, they released benchmarks, with sample units introduced in the second quarter of 2018, and production scheduled for the third quarter. It can carry up to 15 cards and IDs and also has a spring steel money clip for cash. Tyler joined the TweakTown team in 2013 and has since reviewed 100s of new techy items. Growing up in a small farm town, tech wasn’t around, unless it was in a tractor.

Both Delkin and Prograde are very good brands and their cards always perform well with Sony cameras. The ProGrade 160GB card is slightly faster than the Sony 80GB or Delkin cards. My guess is because I only have a Prograde reader right now and their hardware is probably all in spec with each other.
