Why Deterministic Storage Performance is Important

In the days of spinning media, I/O performance was anything but consistent.  When mechanical head movement is involved, response time can vary enormously.  Actually, the variation of I/O isn’t just to do with mechanics as we will discuss in a moment.  However, inconsistent I/O response time is a problem for applications and as tolerances reduce,… Read more »

With LTO-8, Tape Capacities Show No Sign of Slowing Down

On 17 October 2017, the LTO consortium announced the availability of LTO-8, the next generation of LTO tape technology.  LTO is run by three technology provider companies (TPCs), namely HPE, IBM, and Quantum.  Since the first products were released in 2000, LTO media has increased from 100GB capacity with LTO-1 to 12TB on LTO-8.  The… Read more »

It’s Time for Hard Drives to Join Tape In The Archive Tier

This week we’ve seen the announcement of 14TB 3.5” hard drives from one vendor and 12TB from another. It’s hard to imagine the concept of 14TB in a single hard drive when ten years ago we were looking at only 1TB devices. However, these devices have a problem. The throughput and latency has remained relatively… Read more »
