What is the current state of using DNA and other biological matter as a data storage mechanism?

DNA, and other biological matter shows alot of promise when it comes to data storage, allowing us to basically put all the worlds data in the space of a fucking sugar cube<br><br>What is the current state of this tech<br><br>As well as the state of the following tech related to data storage. Specifically long term, high volume data storage<br><br>Quantum storage<br>Yottabyte hard drives (drives using phase change technology)<br>Holographic data storage<br>Graphene memory storage<br>Memristor data storage<br>Topological quibit computing<br>Any other tech related to this<br><br>Known problems with dna data storage is speed, the cost of writing data and the cost of reading data. What is the current state of solving these problems?
