SanDisk Extreme Pro 512GB CFExpress B Card Review – Understanding Sustained Data Transfer, Temperatures and Thermal Throttling

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.

THROUGHPUT

IOPS

Crystal DiskMark pretty much validates specifications once again, however, we can’t explain why our two write sequential results stuck at 796MB/s in the throughput result.  We did the same test on three separate systems separate times with the exact same result.  We might guess that this is simply a compatibility issue with between the card and software.

USB 3.2 – SANDISK EXTREME PRO CFEXPRESS CARD READER

This result demonstrates the performance one might get when using a USB 3.1 Gen 2 (USB 3.2) card reader which has a 10Gbps data transfer rate.

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.

AJA VIDEO SYSTEM DISK TEST

The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.

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.
