SD Association, a non-profit organization responsible for implementing SD card standards, maximized the theoretical limit of SD cards at 128 TB with a data transfer rate of 985 Mbps. The current SD card standard allows for a maximum storage capacity of 2TB, which was highlighted in 2009. However, no SD manufacturer has managed to offer 2TB storage yet. Back in 2016, SanDisk took the envelopes of a prototype 1TB SD card, which happens to be the largest until the date. So, it is highly unlikely that 128TB SD cards will arrive in stores right away.
What could prevent SD card manufacturers from reaching a theoretical limit in trading?
profitable. SanDisk is currently selling its 512 GB SD cards on Amazon at a "reduced" price of Rs 29,585. Thus, SD card manufacturers must also consider the cost factor before making any move, which is perhaps the biggest hurdle to overcome.
Secondly, there is a limited number of smartphones currently on the market. surpbades the maximum expandability of storage beyond 256 GB. In addition, a flash storage available on many laptops starts at 128 GB. Therefore, limited use cases could be another reason for prevent SD card manufacturers from taking bold action.
128 TB SD cards: What is the future?
As reported by the SD Association in their white paper, 128TB memory cards introduce a new type of category called SD Ultra Capacity (SDUC) also known as SD Express. This new standard will be applicable to all kinds of memory cards. SD cards will be supported by PCI Express and NVMe interfaces to provide high bandwidth and low latency storage. As a result, data transfer speed and storage capacity will be exceptionally higher.
Hiroyuki Sakamoto, President of the SD Association, said, "With SD Express, we are offering a whole new level of memory card with faster protocols. cards in a removable SSD. "
