#54 – Are we at All-flash and HDD Array Price Parity?

Chris EvansGarbage Collection

This week, Chris and Martin discuss the subject of price parity between all-flash and hybrid or HDD-based storage arrays.  From Martin’s perspective, he is starting to see vendor pricing getting close to parity and it making more sense to buy all-flash than a spinning media device.  However, what are the issues?  TCO is one – it’s not all about array pricing.  Also, flash offers more opportunity to be Opex focused, as it’s easier to increment flash in an array than adding many disks to maintain performance.

So what about hybrid?  Does it have a position, if the marketing is going all-flash for traditional workloads and all-HDD for archive and unstructured data?  The conversation closes on questioning whether vendors offering rental rather than buy makes sense and whether the industry can afford not to go all-flash.

During the podcast, we mention Chris Mellor’s article on flash revenue.  You can find it here.  We also talk about the Micron 5120 QLC SSD.  You can find some thoughts on that product here.  Finally, we talk about the 40-year anniversary Intel x86 processor.  You can find more details here.
