Top 10 storage technologies over the last decade

Posted on December 30, 2010 by Ray

Some of these technologies were in development prior to 2000, some were available in other domains but not in storage, and some were in a few subsystems but had yet to become popular as they are today.  In no particular … Continue reading →

The future of data storage is MRAM

Posted on November 30, 2010 by Ray

We have been discussing NAND technology for quite awhile now but this month I ran across an article in IEEE Spectrum titled “a SPIN to REMEMBER – Spintronic memories to revolutionize data storage“. The article discussed a form of magneto-resistive … Continue reading →

Save the planet – buy fatter disks and flash

Posted on April 22, 2010 by Ray

Well maybe that overstates the case but there is no denying that both fatter (higher capacity) drives and flash memory (used as cache or in SSDs) saves energy in today’s data center.  The interesting thing is that the trend to … Continue reading →

7 grand challenges for the next storage century

Posted on November 19, 2009 by Ray

I saw a recent IEEE Spectrum article on engineering’s grand challenges for the next century and thought something similar should be done for data storage. So this is a start: Replace magnetic storage – most predictions show that magnetic disk … Continue reading →

Protecting the Yottabyte archive

Posted on November 11, 2009 by Ray

In a previous post I discussed what it would take to store 1YB of data in 2015 for the National Security Agency (NSA). Due to length, that post did not discuss many other aspects of the 1YB archive such as … Continue reading →

Yottabytes by 2015!?

Posted on November 3, 2009 by Ray

Well, maybe an Exabyte a day was way too small for 2009. NSA is now reporting that they may be storing yottabytes (YB, 10**24) of data by 2015 somewhere in Utah. Later reports have NSA reducing this down to something … Continue reading →

Repositioning of tape

Posted on October 30, 2009 by Ray

In my past life, I worked for a dominant tape vendor. Over the years, we had heard a number of times that tape was dead. But it never happened. BTW, it’s also not happening today. Just a couple of weeks … Continue reading →
