There is a lot of digital information in the world — about three zettabytes’ worth (that’s 3000 billion billion bytes) — and the constant influx of new digital content poses a real challenge for archivists.
Hard disks are expensive and require a constant supply of electricity, while even the best ‘no-power’ archiving materials such as magnetic tape degrade within a decade. This is a growing problem in the life sciences, where massive volumes of data (including DNA sequences) make up the fabric of the scientific record.
One solution is to use DNA: a compact, robust molecule, as a storage medium. We call this DNA digital data storage or DNA storage.
Lenovo’s new flagship 2 in 1 notebooks pack in the latest tech you would want to find on a Windows notebook that doubles up as a tablet device.
It is incredibly thin, weighs just 1.34kg and has a 4K screen. The design in solid, made with brushed aluminium and very sturdy hinges. Battery life is between 7 and 8 hours. I did find the fan noise a bit loud at times otherwise overall it is a very capable notebook.
This one will set you back around R29 000 but shop around and compare with other 2 in 1 machines.
