Sunday, May 19th, 2013 How many IOPS can a HDD, HHDD or SSD do?
A common question I run across is how many IOPS (IO Operations Per Second) can a storage device or system do or give.
The answer is or should be it depends.
This is the first of a two-part series looking at storage ...

Thursday, May 3rd, 2012 It is great to see more conversations and coverage around storage metrics that matter beyond simply focusing on cost per GByte or TByte (e.g. space capacity). Likewise, it is also good to see conversations expanding beyond data footprint reduction (DFR) from a space capacity savings or reduction ratio to also ...
