Outlook. With the limits of siliconbased storage devices already in sight, attention has focused on alternative approaches to information storage. As we have described in this Review, DNAbased storage may become an interesting alternative for the current technologies, particularly in terms of storage density. Much progress has been made with regard to error protection mechanisms without much detriment to storage density. A major disad vantage of DNA compared with silicon is the much lower reading speed, which is especially problematic for use in randomaccess memory applications when only a small part of the data is desired. This means that for now, DNA is only applicable for archiving and longterm data storage purposes. A major problem still to be overcome is the current cost of DNA synthesis compared with the costs of siliconbased storage facil ities. However, if we assume a decline in costs similar to that seen for siliconbased storage media (at least partly attributable to improvements in DNA tech nology), it seems likely that it will not be long before DNAbased storage is the standard for longterm data ▇▇▇▇▇▇▇▇▇,172,173. This is certainly the case when the costs of maintenance and storage are taken into account, which are far smaller for DNAbased storage systems than for the siliconbased systems in current data cen tres. Further cost reductions might already be achieved quite rapidly by using quicker but less reliable synthe sis protocols that require less time and reagents. Lower reliability would result in less valid DNA strands, but as the DNA fountain code has already shown, this can be compensated for by using robust and highly flexible coding strategies34. the nottoodistant future.
