DELKIN DEVICES PRIME 64GB CFEXPRESS TYPE B CARD
The Delkin Devices Prime 64GB CFexpress Type B card has listed specifications of 1730MB/s read a 1240MB/s write and is one of the first cards to receive Delkin’s newest firmware optimization.
Although not advertised, we tested this card for both sustained write performance and also monitored the temperature during this test. The highest temperature this card reached was 58°C and its sustained right performance was an incredible 1.17GB/s.
Perhaps the only negative to this card is its size as taking an 8K video with the new Canon EOS R5 would fill the card in just a few minutes.
Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.
This Crystal Disk Info score validates that we are running in PCIe 3.0 x2, and much more importantly, shows the typical temperature reached during write operations.
ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 512b to 65mb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
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.
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.
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 is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features. Advanced load bench-marking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.
