I’ve found very good article about storage today in ServerPipeline. It is titled “Long-Term Storage Solutions”.
The author looks at diffrent types of storage – from acid-free paper and microforms through removable hard drive, to optical disk.
“Tape has been going strong for 50 years. Disk vendors keep trying to write the obituary, yet tape capacities continue to increase. In the past few months, vendors have boosted native capacity to 800 GB per tape, and in May, IBM researchers announced that they’ve managed to cram a whopping 6.67 gigabits per square inch on an experimental tape formulation by FujiFilm.” says Howard Marks in his article.
He also says that “optical formats have a history of long-term data stability but don’t have the density of tape”.
Enjoy the article here.
