128 TB SD cards can replace hard drives and SSDs in future laptops

128 TB SD cards with a transfer speed of 985 Mbps could very soon be a reality

SD Association (SDA), a non-profit organization responsible for the standardization of SD cards, announced the latest SD card version at MWC (Mobile The new SD SD (SD Ultra-Capacity) category, also known as SD Express, adds PCI Express and NVMe interfaces to existing SD cards for high throughput and low latency. It aims to provide an incredible transfer speed of 985 MB / s, three times faster than the best performing SD cards today and 30 times faster than what is needed to record 4K videos. It also comes with a maximum storage size of 128 TB, which is significantly higher than the previous 2 TB limit.

The new SD Express format will initially be found in SDUC (128TB), SDXC (2TB) and SDHC (32 GB) and will be available in SD and microSD sizes. The two new standards will be added to the new SD 7.0 specification and will be backwards compatible with other devices, like all other SD cards.

According to the SD Association, SSD and HDD storage in laptops could one day be effectively replaced with SD Express cards. "With SD Express, we are offering a whole new level of memory card with faster protocols that turn cards into a removable SSD," said Hiroyuki Sakamoto, president of the SDA. "SD 7.0 [the latest specification] offers breakthrough innovations to anticipate the needs of future devices and content-rich, speed-hungry applications."

The use of PCIe and NVMe interfaces to provide faster transfer speeds is a wise choice The protocols are widely used in the industry today and create a compelling choice for devices of all types, "said Mats Larsson, senior market badyst at Futuresource in a statement. "The SD Association has a robust ecosystem with a solid history of integrating SD innovations and has gained the confidence of consumers around the world."

SD Express cards can be used in UHS-I, UHS-II, UHS-III and According to SDA, SD Express host devices, but faster performance, will only be achieved when the card is paired with the 39; host.

As progress towards a 2 TB card is slow, it is difficult to say how long it will take. -High 128TB card to actually hit the market.
