Dean Ambrose™ Posted September 16, 2024 Posted September 16, 2024 With Lexar's latest announcement, we're looking at one of those hard-to-believe situations where a product is so good on paper that it seems like a lie, and then it turns out to be a pufo of epic proportions. But let's start from the beginning: this is all about Lexar's new SD 8.0 card, which promises speeds of up to 1,700 MB/s read and 1,000 MB/s write, the fastest on the market... The fact is that it seems that this memory card is, at the very least, ahead of its time, since it is not fully compatible with any device on the market that uses this standard, especially video cameras, and at best, it works as if it had the UHS-I standard. An SD card so fast it's ahead of its time? Lexar recently announced a new shipment of SD storage cards, including some that we told you about last week that were made of stainless steel, also compatible with the UHS-II standard. But of course the one that takes the cake for its latest releases is the one that carries the SD 8.0 standard, which uses PCIe 4.0 lanes to achieve the speeds it promises (this standard theoretically reaches 2 GB/s). All of this means that only devices that comply with the SD 8.0 standard can take advantage of the speed of this memory card… and currently there are none. Keep in mind that the SD 8.0 standard was finalized just a month ago, and apparently, while Lexar has rushed to launch its first compatible memory card, the manufacturers of compatible devices in which it can be used They are taking things slowly. The SD 8.0 standard was designed to use several PCI-Express interfaces: PCIe 4.0 x1, PCIe 3.0 x2, and PCIe 4.0 x2. Although this memory card is fortunately backward compatible with previous standards, performance is reduced to a minimum in these cases: it will work like a UHS-I SD card that provides just 30 MB/s speed... look at the difference, From the promised 1,700 MB/s it drops to 30 MB/s, about 56 times less. This fast SD card from Lexar was designed to perform similarly to its CFexpress 3.0 counterpart, part of the Lexar Professional series, to have read and write speeds similar to those used by PCIe 4.0. But that's as far as the similarities are concerned, since as we have explained there is no device in which you can use it, and what's worse, its backwards compatibility turns this professional grade SD into a cheap memory card like the one you can buy up to in a Chinese Of course, even though the manufacturer sent a press release mentioning its launch, they still do not have it listed even on their website, and in the same way it is not yet in stores and cannot be purchased. We assume that now, knowing the problem it has at the moment, Lexar will want to wait until the first devices compatible with the SD 8.0 standard are available on the market to start shipping it to stores... https://hardzone.es/noticias/perifericos/lexar-tarjeta-sd-rapida/
