Adata has exposed This is claimed by the first card in the industry in accordance with SD Express 8.0, which offers the read speed and recording, respectively 1.6 Gb/SI 1.2 Gb/s. These numbers are up to twelve times faster than existing UHS-1 solutions, four times larger than UHS-II, and even overcome several basic SSDs at the basic level. Prime Minister Extreme SD 8.0 Express Memory Card will debut with one 512 GB memory option, but we will probably see higher capacity offers when technology and market mature.
SD Express technology was introduced in 2018 with the SD 7.0 standard. However, we can now see that these super -food cards are now becoming a reality, in 2025, mainly due to Nintendo Switch 2. SD Express cards work very much as SSDS in your PC/PS5/Xbox, using PCIe belts and NVME protocol. Even the basic SD Express cards are evaluated for the theoretical maximum bus speed 985 Mb/s (PCIe 3.1 x1). This number is becoming higher and higher, with cards based on PCIe 4.0 x2 capable of reaching 4 GB/SW SD 8.0 standard.
The Extreme Adata Prime Minister is extended with the SD Express 8.0 option, containing the PCIe 3.0 X2 interface, advertised at the read speed and recording of 1.6 Gb/SI 1.2 Gb/s. Despite the impressive claims, remember that the U3 and V30 grades guarantee only a minimum eternal recording speed of only 30 Mb/s. Thanks to its capacity of 512 GB, Adata Premier Extreme SD Express offers built -in LPDC ECC technology and support for simultaneous access to many devices.
SD Express card ratings
SD Express cards have their own speed assessment indicated by “E” and the number. For example, the E150 on the SD Express card means that you have a guarantee of a lasting speed of 150 Mb/s. Most SD Express cards currently available on the market have not been specified with these ratings, returning to the conventional U3/V30 speed class.
Unfortunately, these cards cannot be used too much except Switch 2 and professional video equipment, because almost all smartphone manufacturers abandoned the concept of memory expansion. The implementation of SD Express in phones would mean adding a unique connector and dedication of several PCIe belts with SOC. So we will probably get stuck for now internal unauthorized UFS and NVME (iPhones).
Similarly, MicroSD Express cards are not budget-friendly, they cost up to 25 cents for GB, compared to retail disks, which you can have for 5-6 cents for GB. Considering that both are based on the same NAND mass storage technology, the cost of memory cards based on SD Express will probably fall over time. Adata did not specify the price or window of issuing this memory card, but we expect to hear more at Computex next month.
