New SD cards with 8.0 Specs to support Transfer speed up to 4GB/sec


New Specification SD Cards 8.0 to support Transfer speed of up to 4GB per second

Secure Digital, officially abbreviated as SD, is a proprietary non-volatile memory card format developed by the SD Card Association (SDA) for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita Electric), and Toshiba as an improvement over MultiMediaCards (MMC), and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products.

SD Association has now launched a new specification for SD cards version 8.0. The New SD 8.0 Specification cards support four times more speed capacity than the previous 7.0. The new SD cards have a capacity 4GB/sec (3,940MB/sec) which is more than the SD Express memory cards.

They have achieved an increase in speed as they applied the PCI Express (PCIe) 4.0 specification. You are able to get this speed only when you use a card reader/device that also supports the 8.0 spec. In case you have purchased the new SD card and you have using an old device it will still work once you upgrade your device. You will also have more storage and excellent performance.

That’s a significant jump from the maximum transfer speeds of 985 megabytes per second you’d find in cards built to the SD 7.0 and SD7.1 specs, which utilized the slower PCIe 3.1 interface. The new specification will be available on SDHC, SDXC, and SDUC memory cards say the SD Association, which means it could theoretically be used on a 128TB SDUC card, which is currently the highest amount of memory supported by an SD card.

The New SD card is not yet officially launched for buying, the companies will soon make an official statement to it, stay tuned on Android Rookies for the future updates on the New SD card.
