If someone could give us some advance about this CFexpress type B card?

[FCC102]

Recently, I got a card brand name is Renice! Is there any specialist who could give us some advance on those cards?
The samples would be borrowed for testing purpose.

320| 650 GB CFexpress type B card CFast2.0 320|512|640 GB
RAW VIDEO support 4K 6K
Operation temperature -10°C - + 70°C
Power consumption < 1.5W[650GB]
Sequential Data Read: 1750MB/1700MB/s

if anyone could give me some feedback that would be great!

Do they claim to support the VPG400 specification? A lot of CFe cards will be fast until their cache runs out and then drop to speeds that make the old CF non-express cards look fast.
The thessdreview.com website tests this by copying a large file to the CFe card and see if the windows copy dialog shows a constant speed all the way. So far all 'cheap' cards without a VPG400 rating perform poorly on that test.

Also, the 'CFast 2.0' in the description is a red flag.

That is the geekiest of sites. The good news for me on it is that it reviewed the Manfrotto 128 CFEexpress card I bought as an el cheapo and I have never seen reviewed elsewhere: "Our testing of the Manfrotto Professional 128GB CFExpress Card was a complete surprise to say the least. When speaking of CFExpress Cards, we envision a triangle comprised of sustained write performance, low temperatures and data transfer speeds. The Manfrotto Professional literally blew all but the Lexar Diamond away with sustained write performance at 1.44GB/s while maintaining a low temperature of 57°C."

Congrats on finding such a good price/performance deal!

Here is the datasheet I got! Would this be good enough?
