It’s hard to believe that over three years ago I asked a question on where hybrid drive technology had reached.  I was thinking of the Enterprise market at the time and as far as I am aware, at this stage, no Enterprise storage array manufacturers have yet integrated these devices into their products.  At the consumer level, of course there are products out there, most well known being Seagate’s Momentus XT drive.  But there is another approach to speeding up the hard drive and that’s to use SSD as a cache but in a slightly different manner.  A good example of this is the OCZ Synapse SSD drive which uses software to provide the cache intelligence. Imagine a typical hybrid drive.  Data written to and from the drive will be in blocks matching the solid state component, let’s say 4K blocks.  There aren’t many alternatives to cache management other than to use Least Re...

Amazon Delivers Cloud Archive Storage with Glacier

At the end of August 2012, Amazon Web Services released their latest service offering – a long-term archive service called Glacier.  As a complement to their existing active data access service S3, Glacier provides long term storage for “cold” data – information that has to be retained for a long time but doesn’t require frequent access. What Exactly is Glacier? Many organisations need to retain data in archive format for extended periods of time.  This is for regulatory or compliance purposes or may simply be part of their normal business process.  Good examples are medical, h...
