Review on 💾 Lexar Professional 667X 256GB MicroSDXC UHS-I/U3 Card | (LSDMI256BNA667A) | Enhanced SEO by Michael Hawkins

First: The card is confirmed not to be a fake Second: As seen in other reviewers' screenshots and text reviews, in addition to my own testing on multiple systems (all are another A2 card I have that meets the A2 performance spec), the 256GB card at least doesn't come close to the A2 spec. (I got 128GB test too, don't have high hopes) A2 spec for write: 2000 IOPS MinimumActual A2 write on this card: 550-650 IOPSA2 spec read: 4000IOPS MinimumActual A2 read for this card: 1800 -2200 IOPSTested Performance for IOPS is closer to A1. Unfortunately, the VINE browser was completely empty and untested. At the very least, Raw READ/WRITE performance is close to the advertised speeds. Is this something correct? Conclusion: If you are looking for a MicroSD with A2 specification, it is A1 specification, so AVOID LIKE PLAGUE if IOPS tasks are your goal.
