The Lexar High-Performance SD 8.0 card promises read and write speeds up to 1,700 MB/s and 1,000 MB/s, respectively. According to PetaPixel, the new SD 8.0 card is ahead of its time since it is not fully compatible with any devices that use this standard, especially cameras, downgrading its performance to the UHS-I standard.
Lexar recently rolled out a series of flash storage-based cards, including the Stainless steel variant in Gold and Silver Pro, which comply with UHS-II standards. But the one that gained the attention was the SD 8.0 standard, which utilized PCIe 4.0 lanes to achieve this speed—similar to its Lexar Professional CFexpress 4.0 card. This was possible because the new standard allowed theoretical transfer speeds up to 2 GB/s.
