What’s Wrong with Tape?

Last week I briefly attended the Tape Summit at IP Expo.  Unfortunately due to other commitments during the day I was only able to join the round-table.  To be fair this was probably the part of the day I most wanted to attend – hearing everyone’s opinion generates much more interest than listening to canned presentations.

Optimising Storage Architectures for SSD

Last week I attended Hitachi’s 2012 Blogger Day.  Aside from catching up with some old friends, we were presented with some NDA stuff which will see the light of day soon.  In the meantime, I want to talk about a press release Hitachi made while I was still on holiday (and clearly missed as I returned, somewhat jetlagged). Previously I’ve ... Read More »
