Moreover, the lack of widespread support for the SDUC standard could slow down the adoption of these cards.
The Gist
SanDisk, under the Western Digital (WD) brand, has announced the forthcoming release of groundbreaking 8TB SD and 4TB microSD cards, which are set to become the highest-capacity storage cards available in the market. These new products were unveiled at the Future Memory Storage 2024 conference, marking a significant advancement in storage technology. The cards are designed to cater to a wide range of devices, including smartphones, gaming consoles, drones, cameras, and laptops. They adhere to the SD Ultra Capacity (SDUC) standard, which theoretically supports storage capacities of up to 128TB. However, these cards will offer a more immediate solution for those needing to store large volumes of data directly on their devices.
Despite their impressive storage capacities, these cards come with a few caveats. They are built on the UHS-I standard, which offers maximum transfer speeds of 104MB/s. While adequate for many tasks, this speed may not suffice for more demanding applications, such as high-resolution video recording or professional photography. Additionally, concerns have been raised about potential heat generation and the likely high cost of these cards, which may limit their accessibility. Compatibility with existing devices is also uncertain, as not all devices may support the SDUC standard.
The Take
Western Digital (WD), a leading name in the data storage industry, has once again pushed the boundaries of what’s possible with its announcement of the first-ever 8TB SD and 4TB microSD cards. These groundbreaking storage solutions, which will be marketed under WD’s SanDisk brand, represent a significant leap in storage capacity, catering to the increasing demand for more space on our digital devices. This announcement was made at the Future Memory Storage 2024 conference, an event that showcased the latest advancements in storage technology.
The new 4TB microSD and 8TB SD cards are designed to meet the needs of tomorrow’s technology. They are described as SDUC UHS-I cards, built specifically for a variety of devices, including smartphones, gaming consoles, drones, cameras, and laptops. These cards are expected to offer theoretical transfer speeds of up to 104MB/s. While these speeds are not the fastest available—other standards like UHS-II and SD Express offer significantly higher transfer rates—they are considered sufficient for most consumer applications, particularly in scenarios where large amounts of data need to be stored, such as in high-resolution photography or videography.
What makes these cards particularly noteworthy is their unprecedented storage capacity. The current market offers SD and microSD cards with a maximum capacity of around 1.5TB, making the jump to 4TB and 8TB a significant development. The SD Ultra Capacity (SDUC) standard, which these new cards adhere to, has been around since 2018 and theoretically allows for storage capacities of up to 128TB. However, it is expected to be some time before we see cards that reach anywhere near this maximum capacity. In the meantime, the new 4TB and 8TB cards are likely to be the go-to choice for those who require large amounts of storage on their devices.
However, these advancements do not come without challenges and potential drawbacks. One of the primary concerns is the speed of these cards. With a maximum transfer speed of 104MB/s, these UHS-I cards may not be ideal for certain high-performance tasks. For instance, professional photographers who engage in continuous shooting or videographers recording in 4K or 8K might find these speeds limiting. In such cases, faster cards such as those using the UHS-II standard, which can achieve speeds of up to 312MB/s, or SD Express cards, which can reach even higher speeds, might be more suitable. The lower speed of these new high-capacity cards could therefore limit their appeal to power users who need both capacity and speed.
Another significant concern is the potential for overheating. As the storage capacity of microSD cards increases, so does the amount of data being processed and transferred, which can generate substantial heat. This is particularly concerning for use in compact devices like smartphones and drones, where heat dissipation is already a challenge. Overheating could not only lead to data corruption but could also damage the card and the device it is used in, posing a risk to the user’s data and hardware.
Cost is another factor that could limit the accessibility of these new high-capacity cards. Historically, the price of storage solutions has been directly proportional to their capacity. Given that existing 1.5TB SD cards are already priced at a premium, it is likely that the 4TB and 8TB cards will be even more expensive, potentially putting them out of reach for many consumers. This could restrict their use to professionals and enthusiasts who are willing to invest in cutting-edge technology, rather than becoming a mainstream solution.
Compatibility is also an issue that potential buyers will need to consider. Not all devices currently on the market support the SDUC standard, meaning that these high-capacity cards might not be usable in older or less advanced devices. This could lead to frustration for consumers who purchase these cards only to find that they cannot use them with their existing equipment. The lack of widespread support for the SDUC standard could slow down the adoption of these cards, limiting their impact on the market.
Despite these concerns, the introduction of 8TB SD and 4TB microSD cards represents a significant milestone in storage technology. These cards will undoubtedly be of great interest to those who need to store large amounts of data on portable devices, and they showcase the ongoing innovation in the storage industry. As technology continues to evolve, it is likely that we will see even greater capacities and faster speeds in the future, further expanding the possibilities for data storage and management.
