"what's the read/write time?" It depends upon the amount of parallelism. I did a calculation back in the early 1970's that showed the copy data rate when human DNA is replicated to be very respectable. Serial DNA replication rate is somewhere between 33 and 1000 nucleotides/sec. However, at 50 nucleotides/sec, it would take about *two years* for a human cell to divide, so there is some considerable parallelism. Normal mitosis takes 30-90 minutes, or O(10^6) parallel threads.

Sandia researchers explore a biologically inspired information storage system
George Bachand, a Sandia National Laboratories bioengineer at the Center for Integrated Nanotechnologies, is exploring a better, more permanent method for ***encrypting*** and storing sensitive data: DNA. Compared to digital and analog information storage, DNA is more compact and durable and never becomes obsolete. Readable DNA was extracted from the 600,000-year-old remains of a horse found in the Yukon. ...
