Sustained write disk performance is not advertised with most CFexpress Type B cards today and, in fact, it is not common whatsoever in the flash industry. As much as it is not spoken of, consumer SSDs, SD cards, compact flash cards, and even the latest CFexpress cards, are marketed and sold according to their ‘peak' read and write data transfer speed…or throughput. ‘Sustained writes' are remotely similar to something called ‘steady state' performance where a storage device is pushed to the point that one can identify the speed it will perform at after a period of constant reads and writes to the product. Peak performance is ‘fresh out of the box' speed and sustained performance is lower and occurs with steady reads and writes to a storage product.
Sustained write performance has not been considered whatsoever, at least until the release of the Canon EOS R5 camera, as it never affected the operation of cameras before this. The R5 changed that, in that, 8K, and the highest quality 4K video will not record without a CFexpress card with a sustained write speed of roughly 325MB/s, give or take a few MB/s. It is important to be aware of, however, that typical performance testing does not identify sustained write speed whatsoever. One cannot tell the difference between a card with a 300MB/s sustained write speed or a card with a 1300MB/s sustained write speed, without specific tests to identify these speeds. That's our job.
A big thank you to ProGrade Digital as, on our Test Bench today is the ProGrade Digital 1700 Gold CFexpress 1TB Memory Card, the 1700 Cobalt CFExpress 2.0 325GB Memory Card, and their Thunderbolt 3 CFexpress/XQD Card reader. We can tell you right off that both of these cards differ significantly with respect to sustained write speeds, although both perform just fine in the R5, the 1700 Gold 1TB card making up in capacity where it is just a bit lower in sustained write speeds.
Just as a bit of an overview, both the ProGrade Gold and Cobalt CFexpress memory cards we are testing today have the 1700 designation as that is their ‘peak' data transfer speed. Both come with a limited three year warranty, and as well, the ProGrade Thunderbolt 3 CFexpress/XQD Card Reader comes with a limited two year warranty. Check ProGrade Digital product pricing at the ProGrade website, or at Amazon.
Bethesda the elder scrolls v skyrim. There is no comparison as the ProGrade reader can do the same job as the USB 3.2 Gen 2 almost 2x faster. At then end of the day, ProGrade markets a number of absolutely great storage products but we have to give our Editor's Choice Award to the ProGrade Digital 325GB 1700 Cobalt CFexpress Card as it is the runaway top card in all tested to date. Dozens of 2.5-inch drive enclosures can be found online for between $10-$25 (£15-25) that will let you drop in an old drive easily, and turn it into an external hard drive or SSD.
