This OWC ATLAS S PRO SDXC is a UHS-II V90 ultra-speed SD card. OWC are an American memory and related technology company based in Illinois that I've used for Mac memory, internal SSDs and other computer goodies for decades.
OWC (Other World Computing) are obsessive about high-speed, reliable data and real-world operability for those of us not just in photography, but also motion-picture and audio and music recording industries. They're new to cards, but seasoned in pro digital memory and storage, which explains why this card has the fastest write speeds I've ever measured in an SD card: 258 MB/s read and 215 MB/s write. I use the BlackMagic test via the Thunderbolt 3 port of my MacBook Pro with this Lexar reader.
While cards always rate themselves faster using weasel words like "up to" (which also means "slower than"), I only measured 177 MB/s writing to my next fastest Sony G 299 MB/s (rated) card in the same test. This OWC card consistently measures very close to its "up to" rating, which is excellent.
It's quality made, complete with individual serial numbers, in TAIWAN, where manufacturing costs I'm told are triple compared to dumping it to China like most card makers.
These are pro cards not sold at retail for all I know, so they are in easy-open envelopes that pop right open. When you go through as many cards as I do, my fingers really appreciate not being cut-off trying to slice open a package with a knife to get to my new cards:

Call me a stickler for details, but I really appreciate that inside these envelopes the cards are in classic translucent polypropylene snap-closed protectors. It irks me when other card makers have cheaped-out by just including naked cards locked in impossible-to-open retail packaging.
OWC tells us they use pSLC technology to provide consistent leading-edge performance, endurance, and reliability and are impact, bend, shock, ESD, UV ray, and x-ray resistant.
OWC claims their pSLC technology gives these cards up to 10 times more write life than common TLC-based SD cards. This means you can completely fill your ATLAS S PRO cards reliably over 29,000 times. Whew! No worries about wearing these out.
These work great in old cameras as well, to the limit of that camera's abilities.
