Lexar Professional CFexpress Type-B Card Review (256GB) – Much Anticipated Media Storage Speed

CRYSTAL DISK BENCHMARK VER. 7.0.0 x64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

AS SSD BENCHMARK VER 1.9

The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.The AS SSD results aren’t as appealing as we might like to see but do get a first look at read and write IOPS which appear to be in the general ball park of listed specs.

 

 

 

 

 

 

 

 

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

TxBENCH

TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features.  Advanced load benchmarking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.  Simply click on the title for a free copy.

REPORT SUMMARY AND FINAL THOUGHTS

CF Express Type-B is still relatively new and it is great to see Lexar climb aboard and take the reigns with this new flash technology.  We can only hope that companies like Canon, Nikon, and Sony, along with a wealth of others, catch up and start to understand that increased camera storage speeds aren’t simply a nice to have; they are imperative to capturing the perfect shot, video and increasing workflow.

With respect to the Lexar Professional CFexpress Type-B card, its performance is solid and meets manufacturers specifications, Lexar shows you their confidence in their product with a lifetime warranty, and pricing and availability is much as we might expect for this new tech.  I happened to bring up to the wife that I needed a mirrorless camera and the Nikon Z7 would be a great platform to validate this card even further.  That didn’t go over to well.  Great card Lexar!

  1. At the totally excessive prices for CFexpress, this should be at least 3D XPoint SLC memory. Connected to four PCIe V4.0 lanes (64GBit/s). According to the 4K values, this is TLC memory at best. The Sustained Sequential Write Performance at 128KB would interest me very much.

  2. Thanks for this benchmark, seems to become the next standard in photography. Are any additional information available about the adapter(s)? This would be a nice one for dev purposes.
