Firstly, SSD prices will not match spinning disk prices. Disk drives will retain a greater than 6:1 $/TB advantage over SSDs through to 2027. However, we can immediately recognize a contrasting viewpoint – that, although the acquisition cost of SSDs can be higher than HDDs, the total cost of ownership, which takes electricity usage and datacenter space into consideration, would favor SSDs, as in Solidigm’s report above.

SSDs dominating in performance, power efficiency, even data centre management complexity is nothing new. The 6:1 price per TB ratio is really is going to keep HDDs in play both in the data centre and for home data archives.

The I in RAID once again stands for Inexpensive. (Formally Independant)

eventually the BOM for the parts is going to sink spinning disks - they're simply more expensive to source because of the wide variety of extremely complex parts, motors, controllers, etc.

just a matter of time imho

In the longer-term, agreed. Don't see HDDs going away in the next 5 years (but we might see the beginning of what is essentially a permanent decline).

yeah it's not going to be a fast transition, it'll probably trickle on for at least 5 if not 10. but eventually solid state utopia :D

Until something like Optane makes a comeback to challenge NAND SSD. Something new will 100% come up, maybe not in the next 10 years, but it will.
