For instance, it would take several hours to write an average iPhone photo to DNA. Furthermore, reading DNA requires sequencing, which is also a time-intensive task and requires specialized scientific equipment.

Apart from being time-consuming, DNA storage is also expensive. In 2015, a study estimated that storing 83 kilobytes of data on DNA cost £1000 (approximately $1,500 U.S. dollars). Recent estimates suggest that storing one petabyte of data on DNA would cost around $1 trillion, while storing the same amount using cloud storage would cost $6,000 per month. This huge difference in costs highlights the challenges in making DNA storage commercially viable.

Currently, Biomemory's DNA storage cards are priced at €1000 (about $1,080 U.S. dollars) and can hold only one kilobyte of data, equivalent to a short email. As a commercial product, DNA storage has become even more expensive. However, it's important to note that Biomemory's cards are designed to demonstrate the technology rather than being cost-effective storage solutions.

The high costs associated with DNA storage reflect the challenges faced in bringing this technology to market. The theoretical cost per byte is significantly different from the operational cost. Nonetheless, there is hope that as the technology advances, it will become more affordable in the future. Researchers are experimenting with different encoding schemes to improve the efficiency of writing and reading DNA, which could potentially drive costs down.
