OWC Atlas S Pro 128GB memory card out of the box / SDXC UHS-II V90 rating
OWC Atlas S Pro memory card has 4 kinds of capacity: 32 / 64 / 128 / 256GB, 32GB is SDHC UHS-II V90 in specifications, and 64-256GB is SDXC UHS-II V90, the maximum sequential reading of memory card is 290 MB/ s, write 275 MB/s. The 128GB capacity tested in this test has a total write capacity (TBW) of up to 3660TB, which means that a daily write capacity of 433GB can last for 7 years.
The Atlas S Pro has such good durability mainly because it uses TLC particles and simulates the writing technology of pSLC storage. More suitable for all kinds of cameras, 360 degree, VR and film cameras and other shooting equipment, with strong protection against shock, bending, shock, static electricity, UV and X-rays, and a 5-year peace of mind limited warranty.

In addition to the original 9-pin, the memory card gold finger uses the UHS-II BUS interface to have more gold fingers, so the maximum performance of reading 290 MB/s and writing 275 MB/s can be achieved. It also requires the device to support UHS-II specifications, but fortunately, SD cards have convenient backward compatibility, so even UHS-I devices can use OWC Atlas S Pro memory cards normally.
